Bytestor 100X HI-Speed Compact Flash 4096 MB

Advantages: Price, Capacity
Disadvantages: Reliability, Speed

...besides simple storage; how fast the files can be stored. This has seen the creation of various grades of CF where the speed of access is indicated by a multiple of 150Kb, so an 8x card has an access speed of 8 x 150Kb or 1.2Mb/sec. Regular speed cards are somewhere between 8x and 10x, High Speed is 20x (3Mb/sec) and ultra-High Speed are 40x (6Mb/sec). That's the basics of CF out of the way, so on to the ByteStor card in question... Advertised as a High-speed card with a 20x (3Mb/sec) access time with 1Gb capacity and coming in at only £65 from Amazon (and probably less after Christmas!) it was too good a bargain to miss. Equivalent cards from named brands sell for 3 times as much and surely there can't be that much of a difference? Arriving in minimal packaging but with a typical snap-closed plastic case, it's a pretty standard Type... Read review

So the higher the write or X-speed the better the performance of the memory card. The X-speed for the Kingston HI Speed Elite PRO Compact Flash 4096 MB card is 133x. One x-speed is equivalent to 150 kb's of data transfer... Read review

Advantages: Fast, big on storage
Disadvantages: Price but shop around

...I bought one of these about 2 months ago to use with my new Canon 30D. I took it out on a shoot for the first time and after installing it, the camera flashed up "card error". I tried inserting it a couple of times with no luck. I put my old CF card back in which worked fine so I knew the camera was ok. I then tried this card one last time and it worked. It's been fine ever since but it did shake my confidence in it a little. It does write very fast with no delays worth mentioning. The transfer rate to my PC is good but is far quicker if you use a card reader as apposed to connecting the camera to the PC via USB.... Read review
