for the transcend 8GB 266x cf card I got: 30.3MB/s block write on a 4GB file 37.5MB/s block read on a 4GB file (iozone) 6.9MB/s rewrite this is on a system with 2.6 linux kernel ext3fs and 512MB of ram. > Unfortunately it was the Apacer that broke down, so I wasn't encouraged > to buy more of those.
