The card was installed to make the transition to SSD disks delaying something and not let old space on IDE drives completely unused. To date (approximately 7 months) performs the map (defying the very cheapest type) without any problems their service on Windows 7. The only restriction is that some bootloader (Ubuntu, Acronis Recovery, ...) does not recognize the card, and with these programs no access to the IDE drives is possible. But that is rather on the bootloaders and the PC architecture.
