I couldn't help but wonder if a 150X CF card is good enough for a hard drive. Since a CF card is perhaps a whole lot more reliable than a hard disk drive, it wouldn't be too worrysome for me to have a striped CF RAID, right?
Ultimately, wouldn't it be worthwhile to stripe 4 or more 4GB 150X CF cards on a CF to IDE adapter? Since there's virtually no seek time, why not get 22MB/s × 4? 88MB/s for a hard drive isn't bad, and with no seek time, no spin-up time, far fewer memory loss occurences, why not use a 16GB CF RAID setup as a main hard drive?
