Tested this with a 233x RiData CF card - Linux hdparm -t showed consistent 45MBps reads - most likely limited by the card itself. Was able to boot Ubuntu off the card etc. Build quality seems quite good. Very happy. This is just the converter card - no bracket to mount in a normal drive bay be in... Tested this with a 233x RiData CF card - Linux hdparm -t showed consistent 45MBps reads - most likely limited by the card itself. Was able to boot Ubuntu off the card etc. Build quality seems quite good. Very happy. This is just the converter card - no bracket to mount in a normal drive bay (should be obvious from photos). Keep that in mind - you obviously wouldn't want this floating around in a metal chassis where it can short. Be careful inserting CF card - easy to misalign and bend the tiny pins. If you want to boot Windows off of this do your research - by default it won't work with most CF cards. There are utilities that may be able to help if you want to boot Windows off this. Works great with Linux without doing anything special. Don't expect high-end-SSD speeds or longevity, but great for a small server where you mostly just use the CF for booting and don't write to it much. I was worried this might not have great throughput (some SATA-to-ATA converters have terrible throughput and thought this might use one of those chips), but it went at full speed (sequential reads) with the fastest CF card I currently have. If you need solid-state storage that you'll mostly read from and want good speeds, this seems like a good choice. Read more
