This is one of the first Class 10 SD cards that is actually affordable and doesn't cost much more than Class 6 cards. At regular price it can be a bit expensive, but catch a sale and it's a great deal.
Performance wise the card is great. I have tried it on 3 separate devices, all of which take HD video. The first was a Panasonic Lumix point and shoot camera. Set to take 720p 30fps video, the recording start and stop times were noticeably faster than my previous Class 6 card. When I performed a Delete all content, this card cleared a bit quicker than before. I also used the card in a Canon T1i and there was no lag for shooting both 720p and full HD video. With a previous Class 6 card it worked well, but occasionally there would be a hiccup in recording, especially full HD. The last was a HD pocket camcorder and again, no issues as recording was smooth and starting and stopping was instant.
Download performance is also improved with this card. I would say data downloaded to my computer at the very least 25% faster than with a Class 6 card, which may not seem drastic, but when moving several GBs of data it makes a difference. I also uploaded data from my computer to the card and the same difference was evident.
Overall it is a great memory card. Is it worth updating from a Class 6 to Class 10? If you are using a point and shoot camera and do not take HD video, then probably not. If you are using a quality DSLR camera and/or shoot HD video frequently, the upgrade to Class 10 would be worth it. If you are getting a new camera and will be shooting HD, go for the Class 10. If you will not be shooting HD, a Class 6 will be ok but if you can get the Class 10 for close to the same price, go for the 10.
Overall I can highly recommend this Class 10 PNY SD card. PNY Professional 16 GB Class 10 Hi-Speed SDHC 20MB/s 133x Flash Memory Card P-SDHC16G10-EF (Black)
I bought this card just to give PNY a try since Amazon lowered the price again. I also have the popular Transcend 16GB class 10 so I decided to do a quick test. I did read and write test with a full DVD ripped movie which is about 5.58GB and has combination of large and small files.
Test setup:
- Ripped full DVD 5.58GB
- Intel workstation, dual quadcore Cpus
- External USB card reader.
- Stop watch
- 64bit Windows 7 ultimate
My result
Writing test:
PNY............Transcend
14.2MB/s......17MB/s (Speed reported by windows)
7:00 mins.....5:45 mins (stopwatch)
Reading test:
PNY............Transcend
19MB/s........19.2MB/s (Speed reported by windows)
5:19 mins.....5:18:55 mins (stopwatch)
So far the Transcend beat the PNY in writing test.
I put both cards in my Canon 60D, both started slowing down after 20 frames, frame size is M-Raw. I also noticed the time to clear out the buffer is about the same for both.
Overall, both cards are fast enough for my Canon HD camcorder and Canon 60D video capture.
I bought this card for my Canon HD camcorder so the slow writing is not a problem to me and there is no reason to return for the Transcend.
I would recommend the Transcend if the PNY is more expensive.
Correction:
I had the read test result swapped. In reading, the PNY is bit faster but it's negligible.
Reading test:

Update 5/27/2011
Some reviewers complained that the card doesn't work in FXP and MXP mode. I found that both my PNY and Transcend class 10 don't work with my Canon HF200 which released long time ago, works with class 6. I don't think it's the cards fault but Canon cam doesn't support. If you have newer camcorder then I don't think it's a problem. Otherwise, get Transcend class 6 instead and problem solved.
Not much to say...........compatible with everything I've tried it in including older digicams from Nikon and Canon (works great in my Canon TX1). Love having the 16gb for HD stereo video - up to 4 hours of video goes on the card! It writes fast and so far has performed flawlessly. The best thing is though that it was $29.99 from J&R for the first couple of days it was up on Amazon - I ordered 2 and the price went to $46 quickly.
I have PNY RAM in my computers, so I decided it was worth trying out their SD cards for my camera. The other card I had was a 8GB class 2 card. Stepping up to class ten was a revelation, it is truly a performance increase for my pentax k7. Video recording is much improved (more responsive, faster start and stop) and the stills are almost instantaneous. I'm quite satisfied with my purchase, especially given the price being very competitive for a class 10 card.
Tried the formatted card in my Canon T1i/500d. It took about 14 seconds to refill the buffer of 9 RAW photos (each was 16.3 MB). This leads to about 11MB/sec write speed. I've read that my camera's internal circuitry is capable of at least 17 MB/sec. I also tried writing a file to it using my SD reader on my computer and I get 11.5 maximum sustained write speed. For the price and 16GB capacity the card is good but PNY advertised this sucker as 20MB/sec sequential write speed. Read speed I get 16 MB/sec.
I purchased this product based on the review here. It is not the speed demon I thought it should be as a "class 10." Overall, I think this card is just as good as my Transcend 8GB class 6. I tested these 2 cards on my Canon T1i using continuous shooting in both RAW+jpeg, and Large Jpeg. I then timed how long it took these shots to write to the card before it "recovered" and readied for the next shots. These are the underwhelming results:
The 8GB size is recommended by Canon for my camera. Good enough for 254 of the largest RAW+Jpeg photos. Larger capacity should work fine also.
Transcend 8gb, Class 6:
RAW+Jpeg: 5-6 shots, 10-15 seconds recovery respectively
Large Jpeg: 33 shots, 10-11 seconds recovery
PNY 8gb, Class 10:
RAW+Jpeg: 5-6 shots, 14-20 seconds recovery respectively
Large Jpeg: 38-49 shots, 15-17 seconds recovery respectively
I am not in need of continuous shooting. After 4000 photos on my T1i, this test was only the 2nd time I used continuous shooting. I took 1 star away because of the disappointing speed tests. If I had a "to do over" I would purchase more of the cheaper 8gb class 6 cards or a cheap 16gb class 6. For a Class 10 card that functions as a Class 6 card, this PNY product is OVERPRICED. - Sdhc - 16gb Sdhc Memory Card - Secure Digital - Memory Card'
