I'm also thinking of getting one for my A4000 but dopn't use IDE /SATA much with it as only my boot drive is on IDE but all other drives are powered by my CS-MKIII onboard scsi
I keep thinking I would like to grab one, but I also have a CS-MKIII. 68-pin SCSI to SATA adapters are not cheap, especially ones that support hard drives. I have one for IDE for my DVD-RW, but it only supports ATAPI devices.
I could buy the FastIDE and use an IDE-to-SATA adapter (or one of my IDE SSDs,) or I could find a 68-pin SCSI-to-SATA.
Decisions decisions.
