Bytestor 100X HI-Speed Compact Flash 2048 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

Advantages: Fast write speed, Reliable (estimated to last over 100 years)
Disadvantages: none

...memory cards will function on all Operating systems, including the more popular Microsoft and Apple systems. If you have a different operating system to Microsoft or Apple, then there is no need to worry as it will function on virtually all OS (Operating systems) released shortly before and after the release of Compact Flash Cards. The X-speed on this Compact flash card as well as on all Kingston flash cards determines the writing speed of the card. The writing speed is simply the time taken for a file or files to be copied onto the memory card. The write speed determines the overall performance of the compact flash card. 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: Performance and speed
Disadvantages: Higher cost than lower level models

...Having bought this card to be used in Canon EOS 20D & 40D digital cameras they are extremely rapid and much better than the lower speed Sandisk Compact Flashes or other makes. The cameras have not as yet had to stop shooting to allow the card to catch up to write data during picture taking even in rapid fire sports mode. Have had no failure with data capture and have been used in extreme temperatures, holiday in Australia (39C) and a family wedding in Austria (-10C). The cards didn't seem to lose any performance in the big changes in temperature which can occur with lesser models. I would thoroughly reccomend these cards to anyone prepared to spend that little bit extra the performance justifies the cost. Look out for sale offers on them to make them really good value for money.... Read review
