This review is from: Transcend 8 GB 133x CompactFlash Memory Card TS8GCF133 (Personal Computers)
This card is speedy enough for my tastes. Shooting w/ my Nikon D70s in burst mode: I can record 3fps (frames per second) in raw for the first four shots and average 1.5 sec between shots thereafter (by comparison, my extreme IV 2 GB card gets 5 shots off at 3fps and averages 1.0 sec between additional shots). If I shoot with the transcend card in the maximum jpeg setting the results are even better: 3fps for the first 11 shots and 0.9 sec between shots thereafter.
I was able to read 786mb off the card in 48sec (51sec with extreme IV) using my sandisk extreme usb reader. Writing 786mb to the card from my computer (which I never do) was, however, slow: 105sec compared to 57sec with extreme IV.

Not an alternative to SanDisk Extreme III, Jun 27 2008

First, I am not an expert on compact flash cards. However, I use them in my photogrpahic equipment, such as a Nikon D300. I normally use the SanDisk Extreme III CF. I am concerned with two time measurements. The first is how long the CF card takes to record the image after I press the shutter release. The second is how long it takes to download the contents of my CF card to my computer using a card reader.
I bought the Transcend because the record times appear to be very similar to the SanDisk, and I thought I could save some money. The Trascend was less than half of the price.
The Transcend has great recording times. No complaints there. But to download data from the Transcend to my computer using a card reader takes about 8 - 10 x as long as the SanDisk. I don't know why, nor do I really care.
If money is the driving factor in your purchase, and you don't care about download times, then buy the Transcend. If time is money or if you can't wait 45 - 60 minutes to download 4 GB of data from the disk to your computer via a card reader, buy the SanDisk.

This card is actually Class 4, 26x., Mar 25 2010

This card is not 133x (Class 20). It is Class 4 at best. Now I see how they can sell it so cheap.
I suspected something was wrong at first when I was recording paltry 640x480 video on my Canon 5D.. This is a 2MB/s task.. I got the little 'buffer filling' warning on the right hand side of the display, indicating the card was not keeping up with the bit stream! What the heck!? This is ridiculous for x480. A good rule of thumb for compressed video is 2Mb/s for 480P, 4Mb/s for 720P, 8Mb/s for 1080P. Find those numbers any number of places. 133x should give me 20MB/s+
So, sick that I had just wasted my money, I plugged the CF to my PC and ran CrystalDiskMark with a 50MB file size, representative of a RAW+JPEG write. To my shock and horror, the card is a CLASS 4! (26x). Ran it again simulating a video stream, same result. Now I understood why the card could not keep up with my Canon DSLR.
I posted the picture proof in the 'customer images' go check it out. If you have an older camera or only need x480 this card would work; but will you patronize a company that lies to you?
Unfortunately, shipping is more than the cost of the card; I'll keep this as an emergency backup for when I forget my quality card.
