What is the fastest SD card you can buy for the Nook?

---

Despite being a Class10, I have been informed by XDA members that the 32GB Lexar SD card (amazon dot com slash Lexar-MicroSDHC-Memory-Reader-LSDMI32GBSBNAR/dp/B004AM610M/ref=cm_cr_pr_product_top) that I purchased for my Nook Tablet is not very fast at reading large PDFs and eBooks which is what I intend on using it for.

The term used to measure performance escapes me right now, but they said it was more important than just the fact it's a Class 10.
I searched the forums and can't seem to find the posts mentioning fast SD cards for the tablet, so I'm asking a direct question:

What are scientifically and objectively the fastest SD cards (at least 32GB) for the Nook Tablet?

I'm tired of waiting 7-15 seconds to turn a single page in a large PDF. I am not exaggerating.

currently i have a 32gb class 4 sandisk and i have some epub format ebooks that i am reading now with aldiko. turning pages are pretty quick. the general rule of thumb is this:

if you care about file transfer speeds as in copying/moving files from a hard drive to your sdcard, the higher the class the better.

if you care about performance as in how the files are read which in your case is what i think you want, class 4 or class 6 is the sweet spot.

Also wasn't there some issues with higher class cards and stye NT clashing? I think general consensus is that the class 4 works best the the NT.

i've used 3 class 10 and 3 class 4's

despite the supposed higher read/write on the class 10, the class 4's all ran faster and were more stable.

I think this is what you're looking for.

I'm just a noob , but I think it also depends on what you're running. I dualboot and run CM9 straight off a SD card. I read sequential read/write is what essentially makes the class 4, 6, etc. But for running a ROM on it, it's all about random write. SanDisk is recommended in this case.

But by all means, check for yourself. Hope that helps.

SanDisk's 64GB card is pretty fast on the NT.

I'm running CM7 internal on a 16GB NT. Not sure about speed, but can report on these two brands/capacity.

I have two 16GB Class 10 Samsung cards (MB-MPAGA) and regularly use them to run backups. Used them last night to update to latest CM7 from Team B. They both work with no problems ever encountered.

The card that is in my NT for daily use is a 32GB Class 10 G.Skill that I got from Newegg. No problems with it either.

Attached are results from benchmarks on the three cards.

SanDisk's 64GB card is great!

From Wikipedia: http://en.wikipedia.org/wiki/Secure_Digital

Class 2 for SD video recording
Class 4 and 6 for HD ~ Full HD video recording,
Class 10 for Full HD video recording and HD still consecutive recording
UHS Speed Class 1 for real-time broadcasts and large-size HD videos

Our beloved Nooks can't do any of that. The general consensus is that these such devices just weren't designed to take advantage of the higher speed cards. The test results in the chart referenced earlier bares that out.

Have you tried accessing the the .pdf files from internal memory? You may notice a significant boost in performance...

I am using 16gb class 6 sandisk, speed is good
