- Lexar Professional 600x 32GB SDHC UHS-I Flash Memory Card LSD32GCTBNA600
- SanDisk Extreme Pro 32 GB SDHC Class 10 UHS-1 Flash Memory Card 95MB/s SDSDXPA-032G-AFFP
I had two Lexar 32GB Professional 133x SDHC cards before, but being the owner of some SanDisk SSD's and USB Flash Drives, and the SanDisk Extreme Pro being a few bucks cheaper at the time of purchase, I figured they'd hold up against the Lexar Professional 600x.
Since I couldn't decide, I ended up picking one of each. Here are some tests I've decided to share with anyone trying to make the same decision.
Test Setup: I set my Nikon D7100 Image Quality to RAW. Then I put a card into Memory Slot 1, formatted it, set the camera for Continuous high-speed [CH] and Manual mode, Shutter Speed at 8000, F-stop to F3.5, and the lens cap ON.
I took 100 shots on each card. During that time, I also recorded the difference in speed (which you can see in the video review). Keep in mind, these shots in RAW are about 22MB's in size, with a resolution of 6000 x 4000.
After 6 shots, both ended up slowing down quite a bit. However, the SanDisk Extreme Pro was definitely faster.
2. JPEG (fine)
I took 100 shots on each card. After 15 shots, the Lexar Professional 600x started to slow down a bit. The SanDisk Extreme Pro never slowed down for all 100 shots. That is quite a result!
Test Setup: A USB3.0 connection from my computer to my camera. The computer has Windows 7 x64 Operating System, an i7 980x overclocked to 4.2GHz (6 CPU cores, 12 threads), and 24GB's Triple Channel memory at 9-9-9-24-1T timings at 1344MHz speeds. It uses a Crucial M4 256GB SSD (which is faster than the SDHC cards), so there is no bottleneck coming from the test machine.
While this has no bearing on these tests, I just want to brag that the computer also has a Quadro 6000, fully watercooled (along with the CPU), and overclocked to 665MHz Core Clock. It's so quiet that you wouldn't know that it was on and doing work except for the lights and a little warmth emanating from it.
Ahem, anyways, here are 3 real-world Read tests:
1. Time it takes for all files on the SDHC card to appear in the Windows Folder from the camera.
a. Lexar Professional 600x took 19 seconds to load all files.
b. Lexar Professional 133x took 19 seconds to load all files.
c. SanDisk Extreme Pro took 21.5 seconds to load all files.
That's not much of a difference, although most of the performance for this is coming from the computer.
2. Time it takes to transfer all 2.19GB's of 100 photos to a dedicated folder on my SSD.
a. SanDisk Extreme Pro took 80 seconds to transfer all photos.
b. Lexar Professional 600x took 82 seconds to transfer all photos.
c. Lexar Professional 133x took 122 seconds to transfer all photos.
That's around 27MB's per second for Sequential Read for the Lexar 600x and SanDisk Extreme Pro for photos. You'll most likely hit the specified 95MB or 90MB per second Read Transfer speeds for large video files, but you won't see Read Transfer speeds anywhere near that with photos.
Doing some calculations, you could end up with 1400 RAW files on one of these cards. If that happened, it would take about 5 minutes for all the files to appear in your Windows folder, and almost 20 minutes to transfer all those photos to your computer (if your computer wasn't slow). The Lexar Professional 133x would take 28 and-a-half minutes to transfer all those photos to your computer. That's not much of a difference, in my opinion.
3. Time it takes to delete all the files on the SDHC card in the Windows Folder.
a. Lexar Professional 600x took 11 seconds to delete all photos.
b. SanDisk Extreme Pro took 11 seconds to delete all photos.
c. Lexar Professional 133x took 11 seconds to delete all photos.
Nothing exciting here.
Both SDHC cards are supposed to have up to 95MB or 90MB's per second in Read Transfer speeds, but in real-world tests for photo transfers, it's actually more like 27MB's per second. They weren't actually that much faster than some of the older Class 10 cards (like my Lexar Professional 133x). The real difference you will see compared to those older cards is the Write Speed!
If you're going to get one of these cards, it should be for the Write Speed, which performance-wise, the SanDisk Extreme Pro is the faster of the two. You can see the obvious difference in Continuous High-speed captures between the two in the video, and if you want to shoot continuously in JPEG (fine), then definitely get the SanDisk Extreme Pro.
The real question is... can your camera even make use of the write speeds of these SDHC cards? Even my Nikon D7100 hits a wall when shooting RAW in Continuous High-speed mode. Shooting with that Image Quality, I can stick with my Lexar Professional 133x card and it won't make much of a difference. I would only be able to get my 6 quick shots in, and then I'd have to wait for another opportunity.
The only reason to get any of these cards, and especially the SanDisk Extreme Pro, is if you don't mind shooting in JPEG (fine) mode with a capable camera. Not to say these cards aren't good. They are quite good, but the reason to get them is quite limited. If you're not an action photographer with at least an enthusiast-end camera, then stick with the older, cheaper card, and you really won't notice much of a difference except in the pocketbook, where it really matters (so you can save up for getting a better camera body or lens).
Previously, I was able to shoot a handful of photos continuously if I was lucky, then the camera would stop me from shooting to write to the card. Now, I can keep going and going. It does slow down after about 17 shots, but it still continues to shoot and write to the card, rather than stop me from shooting to pause and write to the card like my old one did. That, I consider a really big deal and a major boon for this card.
I haven't noticed a difference in the time it takes to transfer my photos to the computer, but I think that may have more to do with other factors outside of the card. Format time seems slightly faster, but I have not done any specific test to gauge if that's true or just my perception.
Either way that bottom line is that I'm very happy with it and therefore highly recommend this card.
in the field when shooting wildlife photos, specifically when I shoot up to 20 frames and then stop
to check them all out, and sometimes when I use another card with a slower writing speed, it takes
more time to buffer.
The reason I would want to check the photos is to make sure if I got the perfect
shot or not, so I would decide to keep on going or not, and this card plays its role perfectly and
buffers the data in time, because every second counts in the field, and one split second can give you
an entirely different result. Overall, this card is perfect, I would have gotten the 64GB version, but this
will do for the mean time! GREAT job Lexar !
