I'm not saying SATA is faster than anything, just that from experience I have seen that a Generic machine with a 2.3+ Celeron, Athalon or p4 with SATA drives is much faster that an older Compaq with all the good drives etc. An example of this is that we had a quad 800mhz Xeon ML570, 2gig RAM with a whole swag of scsi drives running RHEL 2.1 and Oracle. This machine ran Oracle queries at 1/2 the speed of my test server that was a 2.4 Celeron with a single 120 SATA and 1G RAM. The Dell 1750 (dual 3.2 Xeon, 4G RAM, 3 x u320 146 in raid 5) that I replaced the ML570 with runs Oracle transactions around 10 times faster.
I personally run my own email on a dual 733 DL380g1 and it run's fine. But the point is, if you need any real processing power you might be better of buying one of the new generation of low end servers like the PE750.

I run Centos on Compaq dl380g1/2/3's and Dell servers. While the Compaqs are strong hardware they are old and frankly the performance compared to modern (cheap or otherwise) hardware is not really that impressive. A dual 1 gig P3 dl380 and ultra 3 scsi drives get significantly out performed by a generic celeron with software raid SATA drives.
Whoa!
Who said U160 SCSI was faster than SATA? That's a common farce! In fact, it's the whole reason why SAS (Serial Attached SCSI) is coming about. SAS can even use SATA drives.
