p.1 #1 · p.1 #1 · CF card speed test "updated"


I got a few new cards so I did a new test. My new Transcend cards 400x which are UDMA 7 cards today are a lot faster than the UDMA 6 version of the 400x card. Both Transcend and Sandisk have updated their cards from UDMA 6 to 7 without saying anything. And the new cards that look the same except the 7 or the Video Performance Guarantee (VPG) pic.
It's 30 sec shooting with RAW in my Canon 1D4. All settings are the same of course. But this time I had the lens on MF and also the camera in M settings to get everything exactly the same. I will do the same test with a 1DX when I buy that body.
ISO 100
1/4000 sec
f/5,6
lens EF 24L
Gitzo tripod RRS head

Conclusion: UDMA 7 cards are improved a lot. And there is a huge speed increase when comparing them against the same older card with UDMA 6. Even when the makers have the same speed on the card.

Transcend 128GB UDMA 7 1000x----- 143 shots in the 30 sec burst
Transcend 64GB UDMA 7 600x------ 133
Lexar 128GB UDMA 7 400x ---------- 118
Transcend 64GB UDMA 7 400x ---- 113
Sandisk 32GB Extreme Pro --------- 113
Transcend 32GB UDMA 7 400x----- 112
Transcend 64GB UDMA 6 400x ------ 82
Duracell Pro photo 32GB 600x -----79
Sandisk Extreme III 16GB--------- 75
A-Data 533x --------------------- 60
Transcend 32GB 133x ------------ 52
Transcend 16GB 133x------------- 46

Thanks for the great work Lars.
It's nice to see an alternative to the more expensive Lexar and Sandisk cards.

Dang Lars - if you were in the US, I'd order a Lexar Professional 1000X card for you to test and then send to me...

Lars, thanks for the helpful tests!

I still have an old USB 2.0 card reader. Would you know if the new UDMA 7 cards can be read by USB 2.0?

(I read a review on a Lexar 1000X saying that it needs a USB 3.0 reader?)

I see Lexar 400X (also 1000X but I don't think I need it) on sale and was ready to buy some. It seems from what you said that these are UDMA 7 now, is that correct?

Also, I have Vosonic 8860 viewer that has a built-in card reader slot? Would this continue to work?

Thanks for all your help.

yes they can but they will be read at a lower speed per the xfr capability of the reader itself.

the 1000X needs a USB3 reader to attain maximum xfr performance results. that does not mean it won't work on a USB2 reader unless its manufacturer put artificial limits on it.

The two Transcend 64GB UDMA 7 600x cards that I bought after your first thread are still looking pretty good! They're getting lots of use here in Utah.

Thanks Lars!

I just bought a Lexar SDXC I, 128G, 400X speed.

I popped it in my old PC (4-5 yrs old), and tried on USB2 card reader, neither one would recognized the card.

But when I put it a new laptop Win7, i7, it can read it.

Any idea? Should I need a new card reader for this type of card?

Thanks,

Kevin

What card reader do you have? And do your old PC have Windows 7 ? Maybe your reader is very old. All my 3 different readers work with that card.

I got it working.

There is a notice on Lexar website.
http://www.lexar.com/support/sdxc-faqs

I have Windows XP, there is a patch update from Microsoft. I updated it and now it works fine.

By the way, I have this card reader.

Ok, I belived you owned a Lexar 128GB CF card. Not an SDXC card. I took that for granted because the thread was about CF cards.

Lars how do you like the 64GB Transcend 400x UDMA7 memory card? It's going for $104 and it is a great value.

I recently bought a couple Lexar 1000x 32GB CF cards. My old Lexar Professional USB 2.0 CF/SD reader would fail and/or corrupt image files when trying to read the 1000x cards. Never had a problem with any brand of slower cards. I contacted Lexar and they indicated that there was a compatibility problem. I was able to read the 1000x card on an old cheapie all-in-one USB 2.0 card reader. Since I wanted faster upload speeds, I sprang for the Lexar USB 3.0 read, and it seems to read the new cards fine.

It's probably the best card when considering money vs performance. I own many of those cards.
