[Q] MicroSD Question - Nook Color General

Just picked up my NC at Best Buy about and hour ago. I have it at home charging and I'm going to go get a couple of MicroSD cards.
Should I go for the Class 10, or is Class 4/6 fast enough?

Unless your running something from the SD card then I'd recomend at least a class 6, you'll get around 11mb/s writing time, otherwise both the ROMs for the nook (Honeycomb & Nookie Froyo) both support installation to the emmc, you can just flash them to your system with Clockwork Recovery.
tldr; if you can find a class 6 or higher for cheap (I got an 8gb class 6 for $12 off amazon) get it, if not you'll be fine with anything truly now.

I am currently using a Class 4 8gb, and have no trouble running apps or even Froyo off the SD card,
Basically if you are just using the SD for apps or holding data, anything should work i would recommend at least class 4 or better, if you are going to be running the a custom rom off the SD while some class4 will work well. I would still recommend class 6 or class 10, Faster is always better.

Posting this from my new NC!
I stopped by Frys Electronics after dinner and picked up two Patriot 8GB Class 10 MicroSD cards. Getting to know the Nook a little before I root and start with the custom ROMs. Gonna load Froyo on one card and Honeycomb on the other so I can try out both flavors and see which one I like better.

[Q] Problem with Class 10 SD Card

I have a Nook Color Rooted with 1.1.
I put Honeycomb v4 on a Sandisk Class 2 8GB card with no problems booting and using.
I got an expensive Patriot Class 10 8GB card and put Honeycomb on it and it freezes at the small "android_" with the cursor flashing after android.
As an experiment, I put Froyo on the Class 10 card and it boots just fine.
Any help would be appreciated.
Patriots tend to have trouble with the whole booting from sdcard thing. To be honest, I think its quite the miracle that you got Froyo running off of it.
Is the problem the Class 10 or Patriot?
Any particular brand and Class you would suggest for optimum performance.
Just biding my time until I decide to put a newer Honeycomb on the internal memory. (Maybe wait for v5?)
I posted this in another thread but my 8gb class 10 Patriot is the only one that has worked well for me. I used a 16gb class 10 Wintec and that worked until v04 HC. I tried a 8gb class 4 Patriot and it was terrible slow.
PSF8GMCSDHC10 is the only card that works well in my NC

Which microSD card is the MOST STABLE and FASTEST for using HoneyComb in SD card?

So I finally got HoneyComb working on my Nook Color (NC), residing in the microSD card using a Kingston 8GB Class 4. However, this card seems to be one of the slowest and using the HC in NC is almost unusable.
Example:
- Screen rotation takes 3-5 seconds
- Opening new app, depending on which app, can take 1-5 seconds
- Browsing certain website can make the screen unresponsive
- etc..etc..
I know that the HC version available in this website is probably still in "preview" or beta stage and some slowdown is expected, but I am not expecting it to be THIS bad. So I think the culprit is the microSD card itself.
However, I have tried many different MicroSD card and none works. I.e. it gives the "decrypt storage" error when booting up the NC. The cards I have tried are:
- Patriot 16GB Class 10
- A-Data 16GB Class 10
- Kingston 8GB Class 6
The ONLY one that works so far is Sandisk. Unfortunately, from SanDisk website, I do NOT SEE ANY card higher than Class 4.
Thus, can you recommend which is the MOST STABLE and FASTEST card? I.e. the ones that did NOT give slowdown per the examples I have given above.
i'm using sandisk 4 GB class 4 HC
nookie froyo, runs fantastic.
Class 10 cards apparently dont do too well. lots of people have had issues with those. class 6 should be OK, class 2 and 4 workk very nice.
Do you have recommendation for a good Class 6 MicroSD card? SanDisk don't sell anything higher than Class 4. I tried Kingston Class 6 and my Nook Color just spit on it...

I am currently running trancend 8gb class 6. Havent had any issues with froyo, HC or Cm7 booting or running.
I'm using a A-Data Class 6 16Gb card with no trouble. I do have 2 Kingston Class 4 32Gb cards and they have the issue with the decrypt garbage when you try to boot up HC from the sdcard. I've also got a Class 10 32Gb Wintec card which I have not had time to test out yet as I just got it the other day.
After a failed Kingston 16gb class 10, I got a SanDisk 8gb Class 4 and it's speedy enough. I notice very minimal slow down on some menus but I don't know if that's just the OS itself (being a preview after all)

That's the exact same card I have, and you did NOT experiences any of the slowness I posted in my 1st thread?
How drastic is the difference between Class 2 and Class 4?
I know that it says that it processes twice as fast, but is it noticeable? Can somebody give an example of when you can actually tell the difference? Playing music, watching movies, booting from microsd?
I have a Sansdisk class 2 8gb card that performs just as well as my class 10 Patriot 8gb (which has booted both HC and currently used as storage for my eMMC CM7 install.)
Sansdisk severely underrates their SD's and many other manufacturers overrate theirs. It is not a perfect rating system.
I would recommend going w/ sansdisk in whatever size you can afford. Class 2/4 will be plenty fast.
Before I switched back to Froyo I was running off the SanDisk 8Gb card from BestBuy - $20 - which I found very responsive. I think it is Class 4, but I could see any label on the card itself or the package.
The SD card speed was not the reason I switched back, it was the lack of other features in HC preview. I can't wait for an AOSP release
8GB Cards
I currently have 2 8GB microsds that I switch between:
-Transcend 8GB Class 6 running Honeycomb from Amazon. Tested it with h2wtest and got 16MB/s write and 14MB/s read. (Not sure if that is a typo on the tool or not and it's supposed to be bits instead of bytes, but that's what it says).
-Sandisk 8GB Class 2 running Nookie Froyo. Tested at 14MB/s write and 18MB/s read.
Both cards run their respective ROMs well, so it seems to jibe with what chisleu said about Sandisk underrating their cards. I could also be limited by the USB adapter I was using, but I had another adapter that was limiting it to 4MB/s both ways.

[Q] Micro SD/SDHC card compatibility for the B&N Nook

Hi everyone:
I have been running 6.8 from my Sandisk 2GB unrated card. Although unrated, the card runs relatively fast with the Nook as measured to my Samsung Captivate or Apple iTouch (2nd Gen).
First Card: I backed up the image from my 2GB to a 8GB A-Data Class 6 card. Now this is where the problem starts. The Nookie boots up but down is acting slow and sluggish. To the point it is unuseable with lot's of FCs. I tried buring a brand new image and it is the same. I also tried the card as a data drive max'ing it out to 8GB and also using it to record video in my digicam, no problems.
Second Card: I then bought a Patriot 8GB class 10 card and copied the image onto it. Even worse. It won't even boot or get stuck in the boot process on the "Customted Froyo" screen. Try other images, and the same things occur. The card also works fine as a data card.
Third Card: Third time's the charm. I got this card from Costco. 8GB, class 4. Copied the image from the 2GB to the Sandisk 8GB, expanded the partition like the others. Worked like a charm and runs even smoother.
My question here is:
1) Is the Nook picky about micro SD cards? Seems like the faster cards are having compatibility issues.
2) For people complaining about performance issues running off of the micro SD card. Could it be caused by compatibilty issues I've experienced?
FYI, I've been running "Customized Nookie Froyo" from my micro SD card for about two weeks now with no problems. This will be my daily driver. I get the best of both worlds, Froyo and the B&N image.
Something to think about
Evidently the NC is picky about cards IF you are going to run from them - which is somewhat more intensive than is intended for an ereader additional storage device.
There are existing threads on the subject, just search TITLES for "card" in this Forum only.
Summary - The Transcend 8gb Class 6 seems to be the favorite. Some Class 10 cards don't work correctly in Nook. A-Data makes great Desktop RAM and crap SD cards. Sandisk is a safe choice when on sale, their Class rating is conservative.
Patriot 8GB class 10
I have the same card and works great. Strange. I don't know why you are having so much problem.
Did you try a new IMg? .3?

I tried .3, 6.8, 6.7, and HC all with boot or performance problems. I have two Sandisk8gb cards now and able to run all images with no problem. Typing in HC right now.

Bad batch? I tried hc .1 .2 .3 no problem. I guess I am lucky.
I have class 4,6, & 10 cards in 8Gb, 16Gb, and even 32 Gb. Mix and match of brands from SanDisk, A-data, Wintec..etc. Only issue I've run into is using any of my 32Gb cards, they just plain do not work right. Whether I use them for just storage or even a ROM running from them they are nothing but trouble. One thing I have noticed tho is DO NOT format the card using Windows before burning an image. You are better off using a3rd party app to format the card, it seems to work much better. Or format them with Linux if you have access to it.
BTW as for the 32Gb cards they don't work well with much of anything. And from reports I've seen on the web it seems to be a known issue where all the mfgs say they can use 32Gb cards but they do not have the software bugs worked out seeing as most people don't own or use them seeing as they are a bit pricey still. At least for a decent one they are
Hey quick question will2live what is the class rating and size on the Wintec card you're using?
I have a kingmax class 10 16 gb card....HC and nookie froyo refuse to boot......well nookie does, but in the next boot, hangs up...
only cm7 runs perfect

Best uSD card to run CM7

I just put one of the CM nightly builds (build38) on a uSD card (sandisk 16gb class 2) and there is a major lag to even enjoy the device. I have been reading about that sometimes class numbers on the cards don't mean too much.
Which card would you recommend to run CM from (Brand/class/where to buy) from your experience?
any class 6 card should be plenty enough (as long as it has enough room for the ROM and stuff) even class 4 should work much better (but still some lag i beleive, idk ive never tried it)
newegg is a pretty good place to shop for them. Heres one such card - newegg.com/Product/Product.aspx?Item=N82E16820211341&cm_re=8gb_micro_sd_card-_-20-211-341-_-Product
There is a long thread about this on here and the class 6 Transcend 8GB card got the most mentions for good perfomance. The probability for issues to arise increases when using cards over 8GB.
I have a class 2 Sandisk 8GB and class 6 Transcend 8GB card. They both work well.
I have been buying the Wintec cards from newegg for a couple months and run them in both my captivate and my nook they work awesome. Class 10 and fast. http://www.newegg.com/Product/Product.aspx?Item=N82E16820161411

I used that card for HC v4 and it was fine.
I've got 4 uSD card: one Dane-Elec 2G no class, one Kingston 2G no-class, one Transend 4GB class 6 and one PNY 8GB class 4. All run CM7 very well, maybe I didn't pay attention but didn't notice much different in performance. In benchmark, the write speed is about 5-7 MB/s.
The higher capactity 16GB card seems to have more problems, other than that every card will do.
You should check into the random read/write performance of small files on these cards. sometimes the class 6 or 10 aren't all they are cracked up to be. Fast transfers of large file yes, but general performance can suck.
sandisk class 2 or 4 cards can have excellent perf. I have a class 10 that is outperformed by class 2/4 and 6 cards.
if you are having problems with crashing, etc. try a basic sandisk and see if perf. is better.
there is a thread about it but i can never find it.

[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.
Midgets... and lots of them

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.

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.
