The 2044 controllers are excellent SCSI controllers. As far as RAID goes, quite lacking. :) But you'll be hard-pressed to find another controller that performs as well on a 486 as it does on a dual PP200. The cards are quite intelligent, which is DPT's thing, and which is why they're quite expensive when compared with, say, Adaptec's offerings. The PM2144 is much better as far as RAID0/1 goes, and for RAID5 I wouldn't use less than a PM3334. Not cheap, but then again, CPUs aren't either, so I sure as hell don't want my SCSI card using the CPU time up. :)

[obkernel] The new SmartRAID V cards (Decade/Century/Millennium) look awesome, and both the Century and Millennium have up to three SCSI channels, each with both external and internal connectors, or one U2W SCSI channel and one FC-AL. I don't know what the programming interface is on them yet though. But they do have I2O support, and as soon as mine come (they should be available this week, I'm waiting as patiently as possible) I will be able to start hacking I2O support into Linux, if only to use these cards. :)
As an aside, I use a PM2044UW in my workstation attached to a Cheetah and a CD-ROM, and a PM2044U in the file server for the CD-ROM and tape drives. :)
