Digital Cameras Photo Reviews of Transcend 16 GB Class 6 SDHC Flash Memory Card TS16GSDHC6ECustomer Review: Works very well with my Sanyo HD1000 camcorder Summary: 5 Stars
Since I'm using this card with a camcorder, this review centers around how well it fares with regard to video-making.
At 13Mpbs bitrate (MPEG-4 H.264/AVC), this card can hold 1 hour 24 minutes video. It's much more expensive than a MiniDV tape, but it transfers to a computer faster than real-time. According to SDHC Class 6 spec (6MBytes/s), that is approximately 3.6x. Using SanDisk MobileMate SD+ reader, I could get 20MBytes/s for reading, which is about 12x real-time.
Unfortunately, since the camcorder uses FAT32 filesystem to store data on the memory card, it can only record up to 4GB per video, so continuous shooting can only run up to 42 minutes.
Unlike MiniDV, memory cards like this one have no magnetic or mechanical problems, and it's pretty reliable. Since there is no mechanical parts, it's possible to operate camera in complete silence. The memory card's non-linear access capability also makes it easy to sort and browse through video footage.
I have two of these cards: one of which I've used since November 2007, with the other one I bought a month later. I've been using both of them without a problem.
Customer Review: So far a brilliant memory card, but get a new SDHC card reader Summary: 5 Stars
http://www.amazon.com/gp/product/B000P9ZBFA/ref=cm_cr_rev_prod_title
This memory card was definitely the right one for me to buy. But do not get one unless you also get a new (or have a) compatible SDHC USB card reader.
I very often use both film and picture mode when I use my new camera, a Panasonic Lumix DMC-TZ5A: (http://www.amazon.com/gp/product/B0011Z6D9U/ref=cm_cr_rev_prod_title).
Recording film fills up a lot of space on the memory card, and buying an 8GB card allows me to use both modes frequently. I filled this card in 3 busy weeks of vacation! Only about 400 pictures, the rest was film.
Using the camera to transfer pictures to the computer took hours! Using a new SDHC-compatible card reader made the transfer to an even older computer many times faster! it took less than half an hour compared to over three h by the cable that came with the camera.
Without timing the seconds and minutes exact, I guess the difference is between 6-10 times using a proper card-reader to any older built in USB access. Go for the card, but get a proper card-reader and good luck.
Customer Review: Memory chip disappointment Summary: 1 Stars
I bought this memory chip when I purchased my camera. The second time I used the camera I experienced problems. The camera would shut down when I tired to delete a picture or view a picture just taken. Thinking it was the camera I spent a couple of months going back and forth with Nikon because when Nikon would test the camera the problems did not occur. I had not shipped the memory chip with the camera as instructed by Nikon. Eventually while talking with Nikon via phone I swapped the memory chip from my camera to a friends exact same camera and the reverse (this person's chip to my camera). With the other chip in my camera I did not have any problems. My chip in their camera, the camera experienced the exact same problems I experienced when that chip was in my camera. So I contacted Transcend and they did immediately replaced the memory chip. Unfortunately, what they sent me doesn't work any better than the initial chip I had so I plan to buy another chip brand.
The positive experience was that Transcend was great about replacing the chip. Unfortunately the 2nd chip isn't any better than the first.
Customer Review: They're mistaken about the Class Rating on Transcend Class 6 cards Summary: 1 Stars
58 seconds into your ski run, 58 seconds into your parachute jump, 58 seconds into your dive with the great whites, or 58 seconds into your little ones first time ever...... Transcend media fails in a GoProHD. The Class designation provided by Transcend is FALSE.
Class ratings on SD cards - how fast they record data. The Transcend SDHC Card FAILS at real world speed tests with some cameras.
The card is overwhelmed with data after approximately 58 seconds of 720/60f HD data from a GoPro HD camera and stops recording.
On less consumer oriented cameras, the buffer in the camera is big enough to deal with the slow write speed up until about 5 minutes, and then the Transcend SD Class 6 card chokes and stops recording.
I've sent multiple contact requests to the US office of Transcend to try and get support, and nothing.
In still cameras - no problem, but if you're shooting video, or thinking about shooting video, this is the wrong card for you. Cheaper cards that are listed as Class 4 work better in the GoPro.
Customer Review: Unrecoverable Data Summary: 1 Stars
The card worked wonderfully for about 60-70 uses (a few hundred photos/videos) over the span of about 4 months, the card was doing its job and I was happy with it. Then unfortunately when we were on vacation with a full days worth of photos, videos and memories collected the card died ( the card was still in the camera and the camera was never opened). After trying everything that could be done in software I contacted Transcend and they offered to try and salvage the data by physically opening the card but whatever happened to the card made any data unrecoverable.
Luckily I always download photos off the card when returning back to the hotel so the data lost was cut to just that one day. Makes me sort of wish cameras had 2 card slots, one of which could be used for data redundancy. In the 10+ years i've been using digital cameras this has happened twice now. That actually seems like a very low failure rate to me but when you only have one opportunity to get a shot any failure is a big deal. Canon / Nikon are you listening? Make that happen please : )
