32gb class 2 vs class 4

Hey guys,
I'm interested in getting a 32gb card. I will be watching movies off it and just basically reading books. Is there a huge diff between the two? I googled and I found the diff write and read speeds but my question is how relevant is it to the user? Like will the movies be choppier or books open slower? etc

Sadly, to throw a wrench in your question, there is authority behind the class markings. Basically, there is nothing stoping makers for marking a card Class 10, even when it can barely do 1MB/s writes. So, how does that answer your question?
It comes down to brand. Sandisk by far makes the best microSD cards, which almost always outperform their rating. I have an 8Gb Class 2, that constantly benches at 5MB/s sustained write, and 12MB/s sustained read. I also have an 8GB Kingston clas4, that can barely hold 2MB/s write, if it is lucky. The other issue few talk about is random reads, where again, the Sandisk is much faster (and random reads are not part of the class specifications)..
So, if you get a decent brand (again, Sandisk), a class 2 should be suitable for all music, and most movies. If you can afford it, class 4 will give you wiggle room.

How about adata? Have you had any experience with them?

personal experience no, but i haven't heard alot bad (actually, better than Kingston in many cases). I know they have decent prices on their cards.
With what i was saying before, it is fair to mention that while slow, my Kingston does still work. But saving things to it was painful, and so i avoid its use. Even if you don't get the fastest card, i think the biggest pain will be filling it once.. after that, using it should be ok..

I see. What about the performance? Saving stuff to it isnt much of an issue to me I think. Im more concerned on the performance. Like running movies off it and launching programs etc the sandisk sounds awesome but the price is much higher

For the use you are planning(movies) the big factor will be sequential read speeds. The class system is too easy for the manufacturers to game. Check the specs for the card you are looking at...if they don't tell you, it's likely because they suck. Sandisk class 2 cards are, as stated, usually better than the class 2 they are rated.

so you guys would recommend a class 2 32gb sandisk over a class 4 adata card of the same size yeah?

Can't really say one way or the other. From reading reviews at Newegg...seems like Adata tech support might be a bit iffy...then again those reviews are usually posted by those who have issues or feel like they have to defend their purchase(ie...fanboi's).
One thing I can see for myself...Adata is the only manufacturer on Newegg to actually list their full specs. Even on the manufacturers pages...only Adata has manned up and posted specs. otherwise they all just fall back on the SDHC specifications for class...which as stated can be gamed a bit.
At the end of it all..it's your cash...spend it the way you feel like...do some research for yourself first.

I have a scandisk class 4 32GB and it is way slower then a smaller class 6 that I have. For me, I don't think I could stomach anything slower then the class 4 for large files.

Sandisk is great. I was originally running Nookie Froyo from a class 2 Sandisk. It was actually pretty solid. I moved up to a Transcend class 6 and it's been good too. Both seem to perform well over their class specification when I'm transferring files and have been very stable.
On the other hand, my friend has a Kingston class 10 which seems pretty buggy. A lot of force close errors, looping boots, etc. Though these could just be a coincidence. Haven't seen him transfer any files though, so I can't judge the speed.

SD Cards..
You should be aware that Sandisk, Adata and others do not actually manufacture flash memory chips, they mostly package and test it - the big boys in the game are Intel, Samsung, Toshiba and Hynix. Depending on where or from whom Sandisk buys the basic chip the specs may be different.

Actually there is a requirement if you're in the SD Association. But in reality anyone can stamp a C10 on a card, especially no-name brands.

Absolutely. AData are junk in my experience.
Kingston and SanDisc are the only ones that are reliable for all devices that I've owned. Others are hit and miss, PARTICULARLY Patriot. I've had 3 Patriot cards that were JUNK in most devices. I had two Patriot SD cards for a camera that were fine but couldn't work right in anything else, and I (stupidly) purchased an 8G uSD card a few years ago for a phone and it was junk there, and I've periodically tried it in new devices for giggles and it's been junk in every single one.
I'll bet a SanDisc C4 out classes any other brand C10 in device like a phone or tablet.
Side note: All 3 Patriot's work just fine on my computer. I did tests particuarlly on the 8G uSD over and over and over and it was fast and reliable in my card reader. Every device locks up or goes slow as hell if it's in 'em. My guess is that they didn't follow specs closely.

So a Sandisk Class 4, 8GB would be a good pick?

I recently bought this on and have found it to be an excellent performer. Loading/watching mp4 movies. The 30 day return window is pretty generous.

SD cards are a complicated topic... not to throw another wrench into the system but you also want to be careful WHERE you buy your card. SanDisk counterfeiting is RAMPANT since a vendor can take a blank card, less than a pennies worth of ink and then charge you some percentage of the SanDisk price while still reaping a huge profit. As unfortunate as it is, real SanDisk cards always seem to just work while the other cheaper cards can be hit or miss. Honestly though the only real problem with off brand cards and the NC I have had is that they don't always boot so good. So I use my SanDisk 8GB C2 (bought from Costco) to boot and my Patriot 16GB C10 to watch movies and store stuff. Buying from Retail, Newegg, or Amazon (Amazon itself, not a sold through vendor on Amazon) should help make sure whatever you buy is the real thing. Good Luck!

[Q] I'm buying a Nook, what else do i need?

I'm buying a nook color as a quick entry into the world of tablets. I plan on using it for reading on the bus etc. But I'm also interested in rooting so I can customize it as well. So I'm planning to dual boot CM7 from the SD card but leave it stock otherwise. With that in mind, what do I need to purchase as a first time Nook buyer interested in modding?
Here's my list:
- Nook Color (of course)
- Aegis Series Enclosure System
- rooCASE (would the nook fit in cases like these with the body armor on?)
- Transcend 8 GB microSDHC Class 6 (read that the class is important when modifying)
- Kingston Flash Memory Reader (to read/write to the SD card)

if your flashing to the emmc class isnt as important, ive been using a plain old class 2 from wallyworld for about a month with no issues.

I have a Sandisk 8GB class 2 form walmart which works fine since I installed the ROM on EMMC.

The speed of the memory card can be a factor with things like video playback, transferring data too and from, etc. Honestly, I would recommend just getting a class 10. The price difference is so nominal that you may as well get something with a little speed. Also, a 16gb isn't much more than an 8gb. So my recommendation...16gb class 10. Something I'm picking up today myself to replace my 8gb class 6 card.
16GB Class 10 for $27.99
16GB Class 6 for $29.99
8GB Class 10 for $19.75
8GB Class 6 for $15.50

I thought about that, but the reviews for larger cards weren't that good so I suck with the 8GB.
The bigger issue is, should I buy it now or wait for B&N announcement later this month?

1) The announcement from B&N about a new Nook on the 24th didn't mention if it was color or not; personally, I'm betting on an update to the original, since the color's only been out for 6 months.
2) Please please *PLEASE* heed my advice on this - if you're planning on running off the μSD card, do NOT buy a class 6 or class 10 card unless you've seen small-block write speed benchmarks. Card Class refers to large-block, sequential R/W speeds, which is good when you're transferring big files on and off of the card, but doesn't factor in quick access or small R/W like you need when you're running an OS from it. I bought a Kingston 8GB class 6 the same day as my NC, 10 days ago, and I almost got to the point of wanting to return the device because of how disappointed I was in it. Then I found this thread -
http://forum.xda-developers.com/showthread.php?t=1005633
and learned about the various card speed tests. I switched to a Sandisk 16GB class 4, and it was like a whole new device. I couldn't be happier with it now.
So, yeah, this is seriously important - read through that thread. And if you live near a RadioShack, they're running a 50% off sale on the good Sandisk cards for the rest of the week.

Strongly agree with this. I got the Transcend C6/8Gb, and had a huge amount of problems (forced closes, and erratic launcher behavior) when running cm7 off of the SD that have completely disappeared since switching to the Sandisk C4/8GB on sale at the Shack. Some radioshacks seem to carry the C2 cards, and some the C4 cards. They are the same price, so it might be worth checking out a few stores if there are several in your area.
If you are just using this as a normal SD card and will be running CM7, froyo, nooter, whatever off of the emmc, then the Transcend is perfectly fine.

Also strongly agree about SD cards. I just bought NC, used a PNY 4gb class 4 to boot off CM7 and it worked but not well, just like hoteladriano - forced closes, erratic behavoir. Will try again with the recommended Sandisks.

I've been using a Patriot 8GB class 10 for a month or so without any problems. Must have gotten lucky. Bought mine at Newegg after being told that a lot of the SD cards at Amazon are fakes, for whatever that's worth.

I"m using a 16 gig class 2 with no issues

I'm using a C6 8 GB Transcend. Saw lots of people rave about them. I'm running the Phiremod/Honeycomb dualboot and see pretty good success with it. Certain apps don't work right and cause force closes (Android Comic Viewer, Pulse) and once those crash I need to reboot to get everything work again. Other than that, its worked fine for me.
That being said, I would agree with everyone here that the Sandisk is your best bet. I may run out to radioshack tomorrow to grab myself another card, just to see how improved my experience would be!

After reading what you suggested and hearing from others I think I'll take your advice. Question is, is it the lower the class the better the performance when running an OS? I'm look at a SanDisk 16 GB Class 2. What do you think?

If I recall, from everything I've read a class 2 Sandisk should be okay, but a class 4 Sandisk would be ideal. If you try radioshack, look through the cards to find a class 4 one. They're not very careful, so they mix the class 2 and class 4 together.

This.
I have a 16gb Sansisk uSD class 2 and everything is good. No FC with apps installed on uSD. I don't store movies on it because I can stream it with CifsManagers and MoboPlayer. I recommend 16gb over 8gb. A lot of games required extra downloads which can range up to 100MB+. Backups can take up space as well.

That ends up really generally being true, because the small-block write speed is precisely what's sacrificed to get better large-block speed, but things can vary so much that I'd stick with either something that's been tested or something from a store with a good return policy.
Without extra details or benchmarks, I would buy a class 2 before I bought a 6 or 10.

I'll love to hear your experience with the new card once you test it.

Yeah, this thread schooled me. I bought a Patriot class 10 card 16gb and OMFG the speed was dismal. It's going back and I think I'm going to order a cheaper Sandisk class 2 for close to half the cost.

Read the linked thread and you'll learn all you need to know. It's the small-block random writes that are important for running an OS, and while it's generally poor in higher-class cards, it varies considerably between models at the class 2/4 level. Also, be sure you're not buying from Joe Blow in Beijing--there are a lot of counterfeit cards out there.

I have the Aegis case for Nook Color, and it's awesome. I've never taken mine off as you have access to all ports including the SD slot, and I've heard that repeatedly taking it off and putting it on again stretches it out and results in a poorer fit. Unfortunately, I bought an Aalto case from B&N thinking it would fit with the Aegis still on, and it doesn't. I don't know about the rooCases, but I've been told that the Rocketfish "Case for Most eReaders" will fit the NC inside the Aegis case, and have ordered one from ebay for $6.99 after shipping.
It's been well covered in general, and you should read the SD card thread everyone's mentioning, but in particular, if you're booting from SD, buy a SanDisk card with a good general rep for fast random small-block writes, then benchmark it yourself with CrystalDiskMark before using it.

What SD card do you recommend?

I am still using the stock 2 gb card that came with my Incredible. I'm looking to get a bigger SD card preferably an 8 or a 16 gb card. What class, size, brand, etc do you guys recommend? Thanks in advance..

They're all pretty much the same. Never heard of a 'bad SD card' company.
I don't think our phones can take advantages of anything above a class 4, so it'd be a waste of money really to spend it on a higher class aka faster card.
This would be my first choice:
http://www.amazon.com/SanDisk-micro...H0SC/ref=sr_1_2?ie=UTF8&qid=1316312237&sr=8-2
It's actually the card I've been using for a year. Works great, quick and still a lot of room left on it.

I'm not sure I ever actually understood the whole speed thing. Is it how fast stuff is read off the card by our phone, or how fast things transfer from my computer into the card?
Sent from my ADR6300 using XDA App

speed ratings are how fast data is WRITTEN to the card.

The Incredible only came with a 2GB card? I'm still using the 8GB card that came with my Eris. Unfortunately nandroid backups take up so much room on this phone, I usually can only store 1. I'm not sure I want to invest in one since most phones seem to be coming with 16GB ones now.

Yeah.
I guess to break it down a little more, our phone only uses
- MicroSD
- Class 4 (classes are just speed ratings for the card and I do not believe our phone supports higher than 4 - not to mention there's nothing practical that you would need to go that quick on a phone anyway)
- Up to 32 (HTC says 32) // Verizon says 16.
I don't know of anyone who has used a 32, again I don't think it's very practical unless maybe you have your entire music library of 20,000 songs on your phone.

I have tried 3 different cards, PNY, Kingston, and San-disk. I have had issues with, PNY and Kingston, but never with any issues with San-disk.

I'm using a 32 GB SanDisk with no problems. I just didn't want to go through the hassle of buying a 16 GB only to replace it with a 32 GB later. I'm only using 12 GB and most of that is nandroid backups that I could probably get rid of.
The sweet spot price wise is probably the $15 16 GB instead of the $60+ 32 GB. But if you want/need 32 GB, it does work.

i have a 32gig scan disk and have had no problems with it.

Be careful when purchasing SD cards on eBay or 3rd party retailers on Amazon because there are a TON of counterfeit cards out there.

I would get the largest size card you can afford...then you can keep as many apps on it, music, pics, etc on it, and save the internal space for cache and not have the phone go crazy if you forget to clear it in awhile.

I personally have an 8GB and I'm considering getting a 16 or above, but 8 is a great size if you have a DECENT music and video collection along with games otherwise I would get a 12GB-32GB if you have tons of media. Click thanks if this helped!

I actually read up on what sd cards perform well as they have benchmark scores on the Toms Hardware site. The Kingston 8gb class 10 is really good. I got around 16 mb/s write speed and 19 mb/s read speed. Not too shaby for $9 on Amazon, and they have the 16gb for $16. Also, if I remember correctly the 16gb performed a little better than the 8gb, but both are perform well.

This right here. While physical stores can also get hit with fake cards, the big dumping ground for cheap chinese knock-offs is ebay and third-party Amazon sellers. Buy one, and you're likely to get a much slower card, the wrong capacity, or just a lump of SD-shaped plastic. you're better off going to wally-world, beastbuys, or a reputable e-tailer like new-egg.
That all said, SD cards are pretty much a commodity item, meaning they're more or less all the same. The Dinc itself I believe can only read around Class 4 speeds, but that's no reason not to go ahead and get a nice fast Class 10 card. Sooner or later you'll probably want to use it in another device or in your PC and it's nice to have the breathing room. I usually buy Sandisk when I buy them, but they're essentially indistinguishable.
And on a tangentially related topic. I see that the Galaxynote 2 is going to be one of the first devices to use SDXC cards... who else is ready to dump 2 terabyte SD cards into their phones to keep their whole lives on? :highfive:

Well I am running a 64Gb SD card in my DINC and it seems to be working fine with Carbon rom. Have not tried the CM 10 yet.. was thinking of trying it tonight..

[Q] Minimum micro SD class for the galaxy note

Hi guys, I am about to purchase my galaxy note next week and I was wondering if anyone could shed some light into the matter..
Which class of micro sd card should I buy? (minimum) I was hoping to get a 64gb but if that would underperform, there would not be much of a sense to it.
The maximum reading/writing I will be doing in the note is probably playing 1080p playback + mirroring it to the tv. maybe some hi definition video recording as well straight to the memory card.. but most often than not, I would play a 720p mkv movie.
Would a class 4 suffice? Any suggestions on which brands I should look at / stay away from?

Class 4 of any decent brand should suffice.
Class 2 cards from Sandisk will also suffice (their read/write speeds are enough for 1080p encoding and decoding). May be a hassle if you regularly transfer a lot of data to and from the card since thats the time when the slower R/W speeds will come into play.

Why get anything less than class 10? If you can afford a Note, you should be able to spare another $20 for a fast sdcard...

class 10 cards can cost upwards of $80 for an 8gig card.

i picked up my class 10 a-ram 32gb microsd for $49.95AU + shipping.
it really depends on what you plan to use your note for. if youre filming 1080p video at the default 17mbps, thats about 2mb/s that you'd want minimum for just filming. so any speed should be fine as long as its above class 2. i just prefer faster cards since theyre getting cheaper.

Where did you get it from? Does it even have a brand?

Why get anything less than class 10? If you can afford a Note, you should be able to spare another $20 for a fast sdcard...

I've read class 10 doesn't always mean fastest read speed or something to that effect. Not always beneficial to get a class 10 since it writes faster but doesn't always means it reads faster. Someone else can probably elaborate for me.

A-RAM is the brand. i bench'd it. write speeds are 11mb/s, read speeds are 14mb/s.
it was one of the random daily specials they had at www.shoppingsquare.com.au a week or so ago.
right now, the next best deal they have is http://www.shoppingsquare.com.au/p_276323_Kingston_32GB_Class_10_Micro_SDHC_Memory_Card

normally read speeds of class 10 are still higher than write speeds. but the read speeds dont really vary much between classes. my kingston class 10 reads at 12mb/s, my a-ram class 10 reads at 14mb/s, my sandisk class 2 reads at 10mb/s. so if all you need is read speed, then any card will do.

even class 2 or 4 on Sandisk it will work fine. i believe just buy a good make one ( not a fake from China ) , but i bought mine Lexar class 10 and work great , i couldnt be happier.

It doesn't necessarily write faster either!
All the class indicates is the minimum sustained write speed under optimal (i.e. unfragmented) conditions. It says nothing about the read speed, which is what is generally important in mobile devices since they are usually used for content consumption rather than creation.
As NZtechfreak has already mentioned, Sandisk Class 2 cards almost always well exceed the class minimums - I've been using 16gb Sandisk Class 2 cards in my phones for a long time now, and I've yet to get one that had a write speed less than the Class 6 minimum of 6MB/s, and the read speed has always been 20MB/s or above.

A good read why Class 4 cards are the best ones to use for your smartphone: http://forum.xda-developers.com/showpost.php?p=14456360&postcount=42

I started out with a Kingston Class 2 32GB I had laying around, and then switched to a Class 10 32GB made by PNY that I got from Microcenter for $59.95.
There was a very noticeable difference in photo taking lag and the media scanner, plus app access on the card. Now there is almost no photo lag, from snap to saving. Haven't messed with the video much yet...

I've Samsung class 10 32 gb. It's really good, but my device started rebooting because of it. "System Process has stopped working."
What I found out is that after removing my micro sd my device is a hell FASTER than before!!!
Maybe a faulty micro sd, no since it works fine in my pc and other devices.
I want to check does any of you have the same problem???

Best Micro SD Card/Class for ICS?

I'm looking at installing one of the ICS ROMs on my N1 pretty soon, but my current Micro SD card is a bit small and I want one that is fast and with a lot of storage.
My question is mainly in regards to Class. I know most people recommend Class 10 for everything, but I read something recently that was suggesting that Class 10 is best only for sequential file reads, and that if you wanted better Random Access time you'd want a lower Class card.
What Class works best for running ICS and apps from the SD card in general?

I have a class 10 Lexar 32 GB myself, got it on Amazon during a sale. I run DK's BCM CM9. Everything is running nice and smooth for me.
After reading many threads I believe that Class 6 might be the sweet spot. Also be careful which brand. Shortlist a few cards and research them. Sandisk are probably one of the best. Personally I'm a fan of Kingston. There's also a good Amazon budget class 10 32GB that is said to work very well.

Thanks, I checked out some benchmarks and the Lexar 32gb does seem to score consistently high on nearly everything (never top, but near the top more often than anything else). If I can't get some more definite answers it's likely what I'll go with if I can find it at a good price.

Brand name is important, but some have to watch price. I had an A-Data class 6 that did fairly well, but not always 6mb. I now have an Amazon Basic 16gb/class 10. No name, but good reviews and is working fine. Have gotten up to 13mb on occassion. Good price.

The info and benchmarks there appear to be saying that the Sandisk 32gb Class 4 is the best for running apps off the SD card, as it has the highest random access time. Class 10 is better for people doing larger file transfers. That said, the feedback I've seen seems to indicate that in reality there isn't that huge of a difference. I think I'll end up going with the Sandisk Class 4; if there is lag I would prefer it to be during large transfers than day-to-day operation.

I use Samsung 32gb class 10 and it works perfect
