I just got a Nook Color and rooted it with Autonooter 3.0
Everything works great. I'm thinking of trying Froyo or Honeycomb on a SD card.
I want to ask which SD card would work best.
Reading through the forums, I have found there are some conflicting information.
On the one hand people recommend Class 6 or higher cards.
On the other hand a number of posters have reported using a class 2 Sandisk card and got good performance.
Since the classification of SD cards only refers to the writing speed, a lower class card may have higher reading speeds than a higher class card. I 'm wondering which is most important for running Froyo/HC on Nook Color, a higher reading speed or a higher writing speed?
For reference here are some benchmarks I found on Amazon.
It appears this Sandisk class 2 card have reading speeds of up to 18MB/s, and writing speeds of up to 6MB/s
[SanDisk 16 GB microSDHC Flash Memory Card SDSDQ-016G (Bulk Packaging)]
This class 6 Transcend card have reading speeds of up to 15MB/s, and writing speeds of up to 11 MB/s.
[Transcend 8 GB microSDHC Class 6 Flash Memory Card TS8GUSDHC6E]

I have an 8 gig class 6 transcend in my fascinate, and a 16 gig class 6 transcend in my NC running CM7. I have a season of an anime I'm watching with Rockplayer on my morning metro ride. Both transcend cards have been great. I have two 16gb Sandisk class 2 cards. One is my "fast one" that's at least as fast as the transcend cards. One is my "slow one" that is unbearably slow for things like transferring a season of anime for watching later with rockplayer. I also have a 16gb samsung class 2 that has performance that mirrors the "slow" sandisk class 2. If I had to get another card right now, I'd probably get another transcend class 6. I've also heard great things about patriot brand, but I can neither confirm or deny those things from personal experience.
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
Patriot Signature 8 GB Class 10 MicroSDHC
Did anybody have any experience with this card?

Are you running a rom (e.g CM7) off the card? Did you ever run a speed test?

Not at this time. What speed test would you like if I loaded one up on the card and booted from it?

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.
I have been searching all over the place for a list of "supported" SD micro flash memory for installing and booting for example CyanogenMods CM7. I have found where people recommend not getting slower than a class 6 but not which brand works best. I am using a Patriot 4GB LX Class 10 and it seems to be doing ok but wanted to know what others were using and what kind of luck they are having.
I'm having good luck with a 4G Sandisk class 4.
Lots of discussion here: http://forum.xda-developers.com/showthread.php?t=1005633
I will add that none of my Patriot SD cards regardless of the class worked consistently or smoothly. After having a ton of weird lock ups and delays (with FC's) I bought a 2GB Sandisk Class 4 and the same exact builds worked fast and like a dream. I then bought a Sandisk 16GB and it too worked perfectly.
Half of my problems were fighting SD card performance issues. There are likely others that are good but it appears the Sandisk Class 4 are a solid starting point.
Agree with Awats
After having problems with Patriot and Kingston I have had rock solid results with SanDisk 2, 4, 8, and 16 GB all class 4. I've tried a couple of off-brand 32 GB class 10 with uniformlly lousy results. Of course YMMV.

I have had zero issue running Phiremod 6.2 off my 16GB Sandisk Class 4 sd (with Dalingren's 4/24 kernel, set at 1200). It has been fast and stable for more than a week. I can't wait for the new kernel that fixed the sleep/battery drain issue.
I bought a Sandisk 16gb Class 2 that works flawlessly with Honeycomb. Only $24.99 at Radioshack right now...if you hurry!
I am using a Transcend 8 gig TS8GUSD C6 with no problems . I think its almost snappier than off of the stock eMMC

How does that Sandisk test out? I have an 8G Sandisk class 2 that tests out as better than class 10 in SD card tools. Not sure if SD card tools is actually testing right. I'd be interested to see how yours tests out.
Just some real world observations that my sandisk cards perform much better than rated, about a class higher I think. I've got an adata and a patriot (class 6 16GB) that haven't given me any issues so far, but I'll never buy another kingston (poor performance, bad cards)

Radio Shack has ALL of the SanDisk cards on sale until 5/14.
I'm running a Transcend Class 6 8GB MicroSD in mine and so far it's been running great. Noticeable difference over the class 4 sandisk I had in there before.

If you're running CM7 off that Transcend, I'd be interested to know if Pulse works without FCs or other issues on yours. I ditched the Transcend Class 6 8G for a Sandisk Class 4 8G.
http://www.appbrain.com/app/pulse-news/com.alphonso.pulse
Which app are you using to test the speed?
Sandisk, 8 GB, class 4 here. The Sandisk class 4 is the way to go, IMHO.
I am using a Transcend Class 6 8GB, running fine. Will buy a Sandisk 16GB to try out.

this.
i've tested many cards with zone bench on the mac. class 4 sandisk outperforms all the others on random read/write of small files. it also coincides with how well my sd card installs run. some cards would run ok but now and again i'd have problems, especially multiple downloads running at the same time from market. I don't have this problem with the class 4 sandisks
for honeycomb: A-Data 4GB class 6 (writes at 6MB/s, reads at about 10MB/s, got it for ~$14, cheapest 4gig class 6 around these parts)
Quite noticeably better than my previous class 2 8gb samsung I got off eBay, which I now use for storage of videos/books & cwm flashing.
I couldn't find a real answer to this anywhere, but I plan on installing CM7 to an SD Card - and boot/run from the card.
Which class of SD card should I be shooting for - and why? Are there any certain brands that work well/don't work well? The same for sizes - is 16GB going to be faster than 32GB ?
Thanks. I'm shooting for a 16 GB internal which should be more than enough space.
Sandisk class 2 or 4

Search this forum and you will find that the Sandisk class 4 disks are great. The best part is they are available at most retail stores, if your impatient. I've been using a 16gb card for a while and it runs stable and smooth.

SanDisk class 4, 16GB
see the other topics here about sd cards, there are some good known resellers on Amazon who have real SanDisk cards, not the fakes that you can finds for cheaper some places online.
Are there known issues with other brands or faster (eg; class 6 / 10) SD cards on the NC, or is it just when booting the likes of CM7 from them?

Some other cards do have known issues or possibly don't live up to their speed class rating. You might get lucky and get a decent one out of a bunch, but its very hit or miss. Other cards have also been known to die after using them for a bit.
If you're looking for something that is reliable and is consistent, then stick with SanDisk class 4.

I tried A-data 4GB and 8GB class 6, they both run great, tried a generic 16GB class 4, horrible slow. Haven't try any SanDisk yet.
sandisk 8gb class 4 seems to work ok for me
if i went anything larger than 8gb i would want above class 4 speeds i think
Read first post here:
http://forum.xda-developers.com/showthread.php?t=1005633
sandisk CL4, 8GB and 16GB seem to be the best bet. faster cards appear to be optimized for speed and large file transfers, but the CL4 and slower cards have better small file read/write speeds.
runnnig CM7 off the card, you want the better small file read/write speeds from the CL4 and slower cards.

Anyone tested any Sandisk Class 6 cards?
Amazon Basics class 10 sdcards work pretty good for me...but i have never run a rom from the actually sd card.
But for $28 (16gb) it actually is class 10-i have all my music and videos and they all perform well. I used to get force closes on my music player back when i had music on internal memory but now that its on external sd i have no force closes
In conclusion the 16gb class 10 amazon basics for $28 has improved my phone satisfaction

This does not hold if you are running off the card. I have a 16GB class 6 Kingston and it runs terribly slow. My class 4 sandisk 16GB runs great.

What monkeymike said.
Pretty much if you get anything but a class 2 or 4 Sandisk(i'd say class 4 for best of both worlds), you run a risk of an unstable system. The benchmark tests seem to put them many orders of magnitude above the higher class cards of other brands.
Plus they seem to be on special just about anywhere i've asked for them. Try radioshack if you are in the US.
I think you'll find that extensive benchmarking of a heap of cards has shown that the ones which are slow to boot are the same ones which have very low 4k random write speeds (as per monkeymike's post reference). The Sandisk 16GB Class 6 cards appear to have decent speeds for 4k random writes, ergo they will be fine to boot from. Other class 6 cards don't perform nearly as well as the Sandisk ones.
I've seen numerous benchmarks around the web showing that the Sandisk class 4's consistently match or beat the class 10's from other manufacturers and I've had great results with them in both my NC and my phones.
That said, its not going to run as well from an SD card (any sd card) as it will when properly installed as the main OS. I know this from experience. I was running CM7 from a generic class 2 for a while and it sucked. Then I got a Sandisk 16gb class 4 and that made a huge difference in usability. But over the weekend I finally took the plunge and actually installed CM7 directly on the NC-and that is a huge improvement over even the best SD card. Still, the Sandisk class 4 is a good way to test the waters.
I have been using Sandisk 16GB Class 4 for a while now, and I need to increase my storage (32GB)
I am confused between these two cards:
Samsung 32GB Class 10 for 1599 INR (29.43 USD)
Sandisk 32GB Class 4 for 1216 INR (22.38 USD)
Which one should I go for ?
If your not looking for fast write speeds or using as a "swapped" internal memory, just go for the class 4, never pay more than you need for memory cards, they date to fast.
I thought greater speed (class10) would be nice,
I was just wondering if samsung is good against sandisk or not ?
Also does samsung cards work with WP7 ?
i am using samsung class 6
16gb
and it works flawlessly for wp7 and native sd (android)

Why not go for the 64GB cards that are available now? They are selling for around $50 (for a SanDisk class 10 even) and they work great in an HD2. See my posts about this here http://forum.xda-developers.com/showpost.php?p=33028241&postcount=9 Basically the same post here as well, but I added a bit more info http://forum.xda-developers.com/showthread.php?p=33102891#post33102891 You can never have too much storage space.
Be careful with class 10 cards as for phone memory use they are not the best.
Good quality class 4 or 6 is best all round card with better sequential speeds that are more in line with phone usage thus better performers & cheaper/easier sourced plus less prone to issues/compatibility ...
i use sandisk
I bought the Samsung 32GB Class 10. It is really fast. I'm using Android via NAND and you can improve your smartphon experience by upgrading your system with this card a lot.
I use a 16GB class 10 Sandisk micro sd
I use SanDisk Ultra microSDHC UHS-1 8GB card.
Worked very well with JellyTime NativeSD ROM and now with WP7 ROM 8858. So cheap and lightning fast. I recommend it for everyone, great memory card!
I use 32 GB Class10 Transcend Extrem Speed (Ultimate), this card has a very well performance with WP7 and NativeSD.

Second place in random speed (4k R/W)!
Which is important for WP7, NativeSD or Nandroid with A2SD, DataOnExt, ect.
