Adaptec SCSI cards

Hi, I have just bought an IBM 18SE hard drive, and I'm now looking for a suitable controller. I'm not after the latest state of the art, and have shortlisted the Adaptec 2940u2w and the 3950uw2, although I haven't been able to find the latter listed on the hardware database on the SuSE site. An internet search seems to suggest it would be ok. Does anyone have any comments on the above cards. This is my first SCSI hard disk, I do currently have a SCSI CDRW but the controller isn't upto handling a hard drive. So I'm busy reading up on everything I can get hold of. Thanks in advance Steve
