And lol, I don't want to get into any debates about how crappy Win8 is. Yes, out of the box it is downright unusable. But, for just $5 you can instantly purchase and download Stardock's Start8 product that will return the Start Button and Start MENU (as opposed to Win8's Start SCREEN) and you can disable most of the really bothersome corner actions and swipe actions from Start8. Then, Win8 is actually pretty tight! It's fast and has WAY better sleep/resume functionality than Win7. My Win8 computers wake up faster than my Galaxy Note 10.1 tablet! However, with Win8, scrollbar contrast is absolutely horrible in browsers and there is no setting or even RegEdit to remedy this. Stardock's WindowBlinds (essentially custom skins for the User Interface) for $10 MAY remedy this and I will be looking into this shortly... So, use the failure of out-of-the-box Win8 as an awesome opportunity to get really good touchscreen laptop or even desktop hardware at really discounted pricing then spend $5 for Start8 and you're all set! ;)
UPDATE (This update was written prior to my May 31, 2013 Update above): As I now have a Nikon D800E I thought I'd share my results for that particular camera (and presumably the D800 as well) as this card will be a likely choice for D800/E users. As mentioned in my original review below, there appears to be an issue with Nikon files and transfer speed being relatively slow with this card. This problem is worse with the D800E. I shoot either Uncompressed RAW + Large Basic JPEG or Lossless Compressed RAW + Large Basic JPEG and approximately 75% of the time my D800E files transfer at 18-22MB/second. This is no faster than transfers from a Transcend Class 6 card. The other 25% or so of the time I get transfer rates as high as 38MB/second. Better, but pretty poor performance from a claimed 95MB/second card. I have yet to sustain a 45MB/second transfer with my D800E files.
In all fairness, I have not shot with any other cards in my D800E and don't know if slower cards will transfer slower than this card does.
ORIGINAL REVIEW BELOW:
First, let's be clear about transfer speeds. And for the record, all speeds I mention in this review are my ACTUAL MEASURED speeds, not manufacturer-claimed or hypothetical limits. I'm talking my real world experience. I use a Transcend TS-RDF8K USB 3.0 card reader and I transferred to a benchmarked 514MB/s write, 551MB/s read Mushkin Chronos solid state drive. See 3rd to last paragraph for camera frame advance rate information and the last paragraph for USB 2.0, USB 3.0 and FireWire information.
My main concern with memory card speed is for computer uploads after a day or night of shooting... First, let me get the ATTO Disk Benchmark numbers out of the way. Doing the 1GB Total Length test, from 64K to 8192K samples, the read speed is consistently at 85MB/s for reads and 71MB/s to 77MB/s for writes. I never got even 86MB/s or more (aside from the initial data transfer rate spikes) once during my testing and feel SanDisk is lying about the card's ability to hit 95MB/s. It never even hit 86MB/s a single time. So, that's benchmarking. Now on to the real world.
I have some conflicting results with these cards (I have 3 of the SanDisk 16GB "95MB/s" cards; 1 for each of 3 cameras):
When transferring files from my Canon S100 card, I routinely hold 80-81MB/s uploads to my computer. Not bad at all! Especially being that they are real world numbers. However, they're supposed to be 95MB/s cards. The only time I ever see 95MB+/s is the MOMENT they start transferring data. Same as any other card, there is that initial spike and then the numbers drop fast. So, 80MB/s is a nice fast upload even though I paid for 95MB/s. I feel like I'm getting shorted by 16%. :(
When transferring from my Nikon D5100 card, after the initial spike I only sustain, *gulp*, about 40-45MB/s uploads. :( VERY disappointing! That's only 33-50% faster than the 30MB/s cards that cost WAY less and not even double the speed of the Transcend Class 6 or 10 cards (Transcend Class 6 is the same speed as their Class 10) that cost 1/4 what these cards do. I'd like to blame SanDisk for this but in all honesty, I think it is something with the Nikon files. I don't see how this is possible but when I put my Nikon files on the Canon S100's card, I get the same 40-45MB/s transfer speeds. Therefore, it's not an individual card's idiosyncrasy. It's probably something with those Nikon files. Makes no sense to me, but I can't figure any other reason. It's not the card, because they all benchmark within 1% of each other and handle Canon S100 files like the other cards and Nikon files like the other cards. If anyone can help me out with this Nikon slow speed issue, please comment here. Thanks. :)
Uploading Nikon files TO the card (write speed) from my computer, I get about 60MB/s. Strange that this is faster than the read speed...
REGARDING CAMERA FRAME ADVANCE RATE... I've reviewed the SanDisk 30MB/s (real life 30MB/s computer uploads with USB 3.0) card and Transcend Class 10 cards (real life 25MB/s computer uploads with USB 3.0) in the past and I found there to be literally only approximately a 0.1% SanDisk 30MB/s card frame advance rate advantage in both my Nikon D90 and D7000. Such a minuscule "advantage" could easily be attributable to my stopwatch button-pressing. I informally tested the "95MB/s" card in my D7000 in Continuous High advance shooting "Lossless Compressed" RAW files only, not RAW+JPEG. I got 9 frames (buffer capacity) at rated FPS of 6FPS and then jerky buffer-restricted advance at 1.5 frames per second. My Class 6 and 10 cards give me the same 9 frames in 1.5 seconds and then continue after the buffer is exhausted at 0.7FPS. In other words, the "95MB/s" card gets you an extra 0.8FPS after the buffer is exhausted. So, card speed means pretty much nothing when shooting RAW files. I don't know about Class 2 or 4 cards potentially slowing things down, but who cares about such slow cards that nobody has anyway? ;) However, though card speed does nothing for RAW FPS, what it may do is raise the JPEG quality and/or size that a camera can shoot in while maintaining maximum FPS (i.e. hypothetically 6FPS forever in Normal Medium JPEG with the "95MB/s" card vs. Normal Small JPEG with a typical Class 10 card). RAW frame advance rate is ALL about the camera's buffer and data output rate, NOT the memory card. PERIOD. It is a myth that card speed matters for RAW frame advance rate.
So, is it worth it? To me, yes. Even at only 40MB/s, these cards save me a lot of time when uploading several to many GB per transfer. At 80MB/s, fuhgeddaboudit, absolutely! If you get paid for photography, time is money and these cards save a lot of time and frustration waiting therefore are worth the money. If you shoot video, you'll save LOTS of time so these cards are totally worth it. So if I love the cards so much, why only 4 stars? Because if you only transfer 250MB per day, these cards will do nothing for you. They won't help your camera in any way and will only save you literally 6.9 seconds per day (250MB takes 10 seconds with a Transcend Class 6 or 10 card or takes 3.1 seconds with a true 80MB/s card like this SanDisk "95MB/s" card). I'm also upset that I usually only get 40-45MB/s uploads and many people are buying this card thinking it will give their DSLRs crazy fast frame advance rates and that is straight-up mythology since it won't even help at all and for them it will be totally wasted money.
A NOTE ON COMPUTER TRANSFER SPEED... If your computer is NOT FireWire and/or USB 3.0 equipped and/or you are using a USB 2.0 card reader on a USB 3.0/FireWire computer, you're NOT going to get better than a hair over 20MB/s transfer speeds regardless of card speed. Just a limitation of USB 2.0, not the card.
- 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).
