mrSHEiK124's SDHC Card Benchmarks

I've been looking all over the web for some decent roundup of SDHC cards that didn't just revolve around SanDisk's different cards and how they stack up - so I figured I'd try and start my own. (can we get a sticky here?)

I'm using CrystalDiskMark for my benchmarking, with a Sony MRW-EA7 reader. I have CDM set to the smallest possible file size (50 MB), which is smaller than the buffer size of most DSLRs (this is good).

Please format your entries as follows, for ease of navigation

Please include an actual photo of the card in your posession, and if possible, where it was manufactured. Go ahead and include comments if you think they're helpful.

SanDisk has definitely underrated this card. Outperforms that POS Kingston of mine. No problems shooting RAW or 1080p with a T2i.

This card is a total POS. There are Class 4 cards that outperform it (write speed). It doesn't hold up to advertised write speed. I lost an entire day's worth of footage from my T2i to this card and stopped using it.

Oddly a better performer than their Class 10 card. Go figure. Never had any problems with this one.

Made in Japan?! Wow, two Made in Taiwan Kingston cards here, more expensive, and not even as good. I feel ripped off.

Notes: I've had this card "fail" on me once (lost all pics/video). But it could have been just the card reader at the time. It's okay, the real trick is when you're recording video w/ the T2i, is to snap a bunch of pics, see if it overbuffers the memory card. Otherwise, it's a great card to transfer files from PC-PC. I still use it as my main card for the T2i.
 
Seems like all my cards read at 20MB/sec.
My cheap Kingston 8GB card is the winner (barely); it has twice the random 512KB write performance of the other cards.

The reader I used, $7 at Frys

Problem is this is so heavily reader dependent

http://www.robgalbraith.com/bins/multi_page.asp?cid=6007

this shows what happens with various readers. This is the closest to a roundup I could find.

Ouch, might explain the difference in speeds between the two 8 GB Kingston 133x cards (me + CuriousMike).

Looks like this won't be possible/accurate unless everyone has the same reader 🙁

IIRC, hooking the camera up (T2i in this case) via USB is slower than most readers, right?
 
I'm not convinced the readers get in the way.

The Rob Galbraith article shows a typical variance of ~ 100-200KB/sec between readers.

There certainly were instances were 1-2 MB/sec were seen, but that is the exception, not the rule.

Looking at the small sample we have here, and Robs site, cards really seem clumped together in 20, 15 and 10MB/sec ranges.

It's a steal @ $50 vs. ~$100 for Sandisk's 30 MB/s. Good for DSLR HD video.
 
I have a 16GB Class 10 Transcend on the way which got a really nice review for 2 different places in terms of speed. I will have it Friday so will post up then.

Pretty disappointed with these numbers.....

If you look at the list of SDHC cards, just taking the first card, you see it range from 16 - 20 MB/sec.

Now that's SDHC. When it comes to CF? I see my Transcend 600x card ranging from 60 MB/sec => 90 MB/sec. It's pretty big of a difference.
 
Although not SD, thought you guys might be interested in these results 😉

summary: reader makes a difference!
card tested: 512mb microsd

rdrcomparison.png


for fun, i was testing all the microsd cards i had (512mb, 1gb, 2gb, 4gb, 8gb, 16gb, 32gb) on just the sandisk microsdhc reader.

i noticed the 512mb performed remarkably well. so i retested the 512mb card on my kingston microsdhc reader, and a built-in sdcard reader attached to the front panel of the desktop, with an microsd->sd card adapter. results were a little surprising...
so i decided to use that card on other reads
 
Here we go....
