As the title states
I used to have an A-data PD7 8gb, that thing was rude fast dam lost it though . I replaced it with an A-data S805 8gb, was nowhere near as fast but was okay but my girlfriend wanted it, so I gave it to her and bought myself the 16gb version of it. But the 16gb version is even worse than the 8gb version, when near full capacity the drive write performance is shockingly bad and i think the read performance is erratic at best.
So I'm looking for a good 16gb (or even 32gb) fast read/write drive, have had a look at a few reviews but they're no substitute for real world tests, so I want to here about what drives you lot have and if they're any good.
Oh if I could find a 16gb PD7, I'd buy it lol.
I want something that performs like this: (My really old A-data PD7 4gb - the 8gb performed roughly the same)
I am using an USB flash drive of Sandisk and I am satisfied. There are some more in the market like OCZ and Corsair. Both have drives of 16GB capacity though they each look very different. Corsair went with the more standard approach of a normal looking flash drive. OCZ on the other hand went with a tapered credit cards style drive that is intended to fit into your wallet.
kingston are also ok
Anyone got any data to backup their opinions?

Have been looking at Super Talent Luxio but online reviews seem inconsistent though.
Would love to get Buffalo Type R 16gb (http://www.buffalo-technology.com/p...es/ruf2-rs-super-high-speed-usb-flash-type-r/) but they are far too expensive and by all accounts quite a big bulky USB drive.
The new esata/usb (http://www.ritek.com/p2-pro4-eSATASSD.asp) devices look quite good but they are still in their infancy and a little to big to put on my keys
Evening XDA!
So... It's time I upgraded my HD2's capacity. 16GB MicroSD's are now reasonably (ish! @ under £30) priced so that's what I want to go for. Most are Class 2 but I've seen a few Class 6s knocking about too.
Is the speed difference, in reality, a massive issue? Stuff I do that perhaps might require speed:
Watching XviDs in TCPMP
Taking photos
TomTom/iGO
Music
Will I notice much of a difference between the two classes of cards?
Any feedback is much appreciated! Thanks!
u just can compare my
kingston sdhc 8gb class 6
to
sandisk sdhc 16gb class 2
i could figure out a speed advantage of the class 6 about 0.8 mb per sec
my 16gb class 2 got 3.8Mb/sec
my 8 gb class 6 got 4.5Mb/sec
copiing the same file....
if somebody got different rates pls post them there.
i never had any problem with the lower data transfer rate of my 16gb sdhc, smooth vids, instant starting apps, nearly same "short" install time for apps
Ps.: i was copiing a 7xx Mb video file to my HD2 in HDD mode
I have a class 2 16gb in my HD2 - I've had no problems with the speed.
watching AVI files with coreplayer is always smooth, tomtom loads up in about 3-4 seconds.
Remember the read speed is a lot higher than the write speed.
Generally you are going to be OK with a lower class. There are however certain things that a lower class memory card will limit, like HD video playback or a high speed game installed on the card (I think Asphalt is a good example of this).
You have to decide what your going to be using the card for and adjust how much you are expecting to spend accordingly.
Be aware that if you are going for a reputable brand then buy from a reputable site. Buying a Kingston or Sandisk from Ebay for a knock down price may mean you getting a cheap knock off. Tread carefully, and give this article a good read, give you a better idea of how easy it is to buy a knock-off card.

Hope this helps
I have been wondering the same because I have been debating on buying the new Kingston Class 10 16GB MicroSDHC card but if the HD2 can't fully utilize the speed, I will probably splurge for the SanDisk 32GB MicroSDHC card and get rid of a few of my 16GB MicroSDHC cards. It is kinda a hassle to carry around a card full of movies, card full of music, and a card full of pictures so I would love to get a 32GB when the price comes down a little more.
Anyone know any reputable sites??? I'm in Australia... So hard to find one to ship Australia and cheap!
I'm after the Kingston 16GB Class 10 card!!!
Thanks a lot for the tip guys. I'll definitely have to have a think about whether I'll need the extra speed, of the top off my head I don't think so but there's a good chance I'll be slapping a few PSX ISO's on the SD card in the future which I guess might be a factor!
@above - unsure of Aus sites, but stay away from ebay as another poster said. 99% of stuff from China (and a lot of the stuff local too) is cheap, low capacity memory hacked to appear to be 16GB and often enough they even include viruses on the damn things too!
UK buyers - Play.com are doing Class2 16GB's for £28 delivered (+Quidco cashback, www.quidco.com)

the only place in oz i could find a 16gb card for my hd2 was vodafone. it wasn't cheap ($89aud) but i've not had any issues with it. it says it's a class 2. i'm sure i read here on the forum that the class really isn't an issue with the hd2 anyway.

Umart sell the Kingston 16GB Class 2 Micro SD for $55. Unfortunately it's the only one they sell (no class 6 available on the website). Have purchased several times from them with no issues.
I did not even know there was a difference in classes. Glad I read this thread.
Class 10 SD cards
Anything over class 2 (which means it can read at a minimum or 2Mb sec) will be a waste of money on a mobile phone. Class 4 and up to the latest class 10, are designed for the speed needed on high end digital cameras that shoot HD videos.
Save your money, buy a good quality, genuine class 2 card, you will not see any difference on an HD2 with a class 10 card in it.
Some users reported that after changing their bundled class 2 card with class 6, music, album etc are up to 3 times faster in loading.
I just ordered a class 6 card to change it with mine class 2, will report about it.
Class
Im using the 16 gb kingston class 2 and it works like a sharm... if you are really picky you can go with a higher class card but be prepared to add some extra cash for a tiny bit of quicker preformance
Just so you will understand how the cards are built there is not much diference amongst the classes. This cards all have 16 Gb space whitch cover the tiny sd card. the diference is that on the higher class cards, the bytes will be shared out in a much more constructive way so it makes it easyer for the phone to read the data. we talk up to 2 seconds faster from the lowest class card to the highest class card. I belive thats from class 2 to class 6.
Good luck with your choice

This is worth it, take it from someone who was looking for something other than SanDisk 32GB C2 I have been waiting for Kingston's 32GB C4 for long time and when it came out I got it though offical site for $159.
Yeah, I ordered one of these last week from newegg along with an otterbox defender case for $33 w/free shipping for both.... not too bad at all. Should be getting them today. Has anyone used the Kingston class 4 32gb card for running android on the hd2?
Sent from my HTC HD2 using XDA App
Well, far as I know people do claim the R/W IOPs for HD2 when card inside the device won't go beyond class 2 rate but some who did use class 4-6 cards said they did see major improvement in terms of loading OS/Apps from mSD card. Anything beyond class 4 is an overkill on HD2 that I accept unless you are moving around massive amount of data and use HD2 as your mean to transfer it, in that case just buy thumb drive.
"Sent from my PC using THE hand" lol
I was in a Fry's Electronics the other day and I saw a 16gb Class 10 microsd card for $32.00. Don't remember the maker but it was not name brand, that is extremely questionable
wow
my videos which are about 12g play almost instantly now i love this card and the free usb reader, thanks kingston
Ya this card was worth waiting for hell I shot up an storm in this section comparing other vendors. Now I have the SanDisk 16GB C2 card not sure what to do with it, hopefully I can sell that cheap.
same
stuck with the sandisk
I ordered this 32GB class 4 card from Kingston and it is much slower then my old SanDisk card. Booting Android took over 5 minutes and after that the device still is VERY slow.
With its card reader I could copy my files onto it with 3-4MB/s.
Then I installed SKTools under Windows Mobile and used its benchmark tool to compare my SD Cards:
My old SanDisk 8GB card (stock one from the blackstone, afaik class 2): ~6,6MB/s reading and 1,1-1,5MB/s writing
The new class 4 32GB Kingston card: ~2,2MB/s reading and 500-700KB/s writing
So I can't use Android with this crappy SD card.
Ya IDK man same on my end. Took me 25min to traf 320mb files, ATM showing me 116min to traf 4.1gb.
i got kingston 23gb class 4. really disappointed takes forever to transfer. but speed test shows its class 4.
http://forum.xda-developers.com/showthread.php?t=861232
oh yeah i got the one from frys it rocks to bad its not 32gb.
I would stick with SanDisk.
I wanned to try out a faster card so got a class 6 Kingston 8gb.. while it loaded things faster, it caused severe stuttering and lagginess at times.
Upon reserach i found, kingston, and many other cards are not the same quality grade as sandisk, i am told in order to be price competitive they buy crap from others at cheap and stick thier name in it. And sometimes they buy rejects from sandisk, toshiba, samsung etc and brand them.....
Unfortunately i cant remmeber the links i researched....
So i would stick with sandisk, or another proven manufacturer....
UThis is total BS, I started it at like 6PM and now its 10:40PM and still 78min's to go WTF and its just 4.2GB music files avg at like 3-6mb/ea. Now I remember putting the whole dir in SanDisk 16GB Class 2 in less than 40min. So WTF does it take so long? Also as I wrote to Kingston CS ill share it here.
To make the file transfer go faster you have to directly allocate the file in memory thus saving time for R/W IO access. I did test many times but I am not even sure HD2 is following SD 2.0 or is it just this POS card no were close to even the stock SanDisk's.
Test: Dir with 5 files at 5mb/ea so thats 25mb. If you copy each file you reduce the time by 3x but if you copy the dir all the objects inside takes time to allocate for some reason.
PS: I am thinking about now getting SanDisk 32GB Class 2.
***UPDATE***
3.85GB

--------
SanDisk 16GB Class 2 = 26min

I also don't understand this.. I have a 16gb C2 card and wanted to experiment a lot with the various android roms out there, so thought a C4 would be the answer. ordered a 16gb C4 and it is always slower than the C2. a full 30 seconds on booting Android.
This confuses me.....okay okay .. thats not hard to do, but as far as I'm concerned if a card is rated at twice the "constant" speed of the other .. it should be faster...

I think it really depends on the card and not the class. I have a couple of Class4 and Class6 cards with identical builds of android and my class2 16gb continually outperform them in boot times and general speed. Class only designates write speed and there is a lot more to an SD card's performance that is not captured in the class designation.
ATM I am thinking about returning the Kingston 32GB C4 as I spoke to Kingston Tech Support and might go with SanDisk 32GB C2. Alot of people say SanDisk is superior and is faster for some reason and getting close to class 4 rating.

I can only quote my experience and that is that kingston C4 is NOT fast at all.
Good luck to you.. and if you find the San Disk C4 is sooo much faster than the C2 can you report back please .. ?? So I can go get one
I just bought a kingston 32gb class 6 micro sdhc but when ever i put it in my hd2 it just freezes up and as soon as I remove the card it works fine again.At first i thought that it was a fake so I:
1)performed multiple tests,
2)reformated a 1000 times,
3)even putting 20gb of data just to make sure.
Turns out that it is authentic and it works perfectly on my girlfriend's htc BalckStone it also worked when I installed NAND (which i later removed due to insufficient memory).Ive been searching for days, I think its a windows mobile issue, any tips??

LOL you are way to funny man as you said "I just bought a kingston 32gb class 6 micro sdhc" and then on top of that "Turns out that it is authentic".
I am guessing you got this card from eBay? If thats the case then its fake ill tell you why as there is no Kingston 32GB Class 6 card ATM. My best bet is you do extended data testing on it and verify the content to make sure its not corrupted. But if I was you I wouldn't do any of this as ill return that POS, why take chance with your data? Also NEVER buy memory cards via eBay or else you will be pwned with notorious chinese fakes.
But for those who actually thinking about buying the legit Kingston 32GB Class 4 microSD read below and think twice.

It's class 4 but it's very expensive.. too much money for just a SD card
Has anyone been able to find any good deals on a Micro SD Card for our Nooks? I am looking for a 16 or 32 gb. With a high class number 6 would be fine.
I don't know about good deal, but I went with this Kingston 16GB one (Class 10). It looks like it is priced about 45% of list price if that helps.

I use these sites and have pretty good luck. Should be able to get a 16GB CL10 for under $50. Hope it helps.
Meritline Sometimes slow shipping.
Supermediastore
Buy.com Sometimes you need to dig through the menus to find good deals.
just wondering
do you really need a high class sd micro what are the benifits as far as speed for movies music ?
trying to make a choice speed or size i mean is the speed only for running apps from sd card as i will more than likely just use it for movies and music thanks
This is probably the best price you'll find for a Class 6 without waiting around for a sale:
A-DATA 16GB Class 6
I have this one and have been very pleased with transfer speeds. My dad has the one above, and the speed are pretty comparable. The Class 10 writes a little faster (can get Win7 to report above 10 MB/s) but A-DATA is a better known brand than Wintec. By which I mean, Wintec is way cheaper than competitors:
Wintec 16GB Class 10
You're not going to be able to get a fast 32GB microSD without shelling out close to 100 bucks.
At local Target for $17.99, Lexar 8GB Class 4. Perfect for books.
I got a 16GB Class 4, Patriot brand MicroSD card for $27 off NewEgg.com. No Tax or Shipping. Arrived in my mailbox 3 days later. Worked fine out of the box without issue and seems to transfer about 3-4 Mbps when writing data to it. Class 6 or higher should be unnecessary unless you're recording live video to it or simply impatient I'd think.
I went for Class 10 as I plan to put apps on it to save space on the internal storage. I did that a lot with my old Palm.
Sent from the XDA app on my NC (1.0.1 w/A-n 2.12.25)
I just bought any old 16gb. Class 2. It's good enough for what I use it for. Video plays back fine on it. And I don't really see the point of apps2sd on this. I mean you have almost 1gb of space for apps.
no you only get roughly 400 to 500 megs before you can't install anything else on it. I have the same problem with my dInc.
Why is that? Doesn't it have ~5GB of user space?

If you use a different home screen than the standard B&N one I use the mini info widget. Is free and takes up a 2x1 spot. Tells battery life, space left, and SD space left.
The only advangage of getting a high speed sd I see would be if one wanted to run ubuntu or the dev froyo. Nice speed boost.
Sent from my NookColor
Weird. On my HTC Desire I have craploads of apps installed. I haven't gone under 600mb out of 1gb free.. Dunno how you can fill it up considering apps are so small.
FWIW, I now use a Wintec 16GB Class 10 in my MT4G and it has lived up to expectations. I tested it to write at better than 10 MB/s with CrystalDiskMark
The Nook inherited its SanDisk 8GB class 4... which is a solid card.
I'd buy the Wintec again in a heartbeat though... Its super affordable on Newegg.
BTW... USE DROPBOX!!!! if you don't have it... click my link and get an extra 250MB with your free 2GB account. Its soooo handy to have my extra files on the cloud. Especially my Titanium backups.
This will be coming soon if you want to wait. It's one of the first high class (6+) 32GB cards.

Patriot SD cards are not a bad deal just don't expect to be able to use them with Honeycomb. The Honeycomb thread is only too full of other members like myself who found them to be really SLOW regardless of the rated class! Replaced it with a Sandisk and to my surprise, HC woke up from it's laggy slumber and was as snappy as the "preview" version could probably be. I'm using the Patriot card in another android device now and it's fine for far less demanding duties.
I was hunting for a good fast NC card and ended up with this 8GB card:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820208453
It has very good speed ratings for a reasonable price.
I couldn't find a good deal on a 16GB card that REALLY runs at class 6 or better reliably. That's why I ended up with the 8gb for now.
I did, however, get one of these 16GB Patriots for the wife's new Optimus V.
San Disk is the way to go. Using a class 4 and its pretty good for speed, reader on nook is class 6 so close enough.

The Patriot 16GB (that this thread is about) - seq read/write 17.6 / 4.5 !
Good performance for raw storage, prob not great for Roms.
