Hey,

I look to change my server from scsi to s-ata

i have the following in my mind:

-Controller: Promise SATA300 TX2plus, 2 Ch. SATA Controller
-Disk: Samsung SP2504C, SpinPoint P120, 7200rpm, 250GB, SATA-II

as you remark, cheap, cheap, cheap :-)

i found some articles online about the promise-controllers SATA150 for
Kernels 2.4.x and 2.6.x but nothing about the SATA300.

Somebody experienced??

Thanks,
Roger


If you are able spend a few more bucks, you might want to get a 3ware raid controller. We just put one in a server and are quite impressed with it. The server has 4 drives, and the we set it up RAID 5 with a spare, the fourth drive stays spun down until you pull one of the other drives, then it spins up and rebuilds the volume.


I have thought about building a RAID box and the issue of hardware over software RAID keeps coming up.

At present I am using the onboard SATA and PCI-SATA card for Software RAID. I saw a low cost SATA-II with NCQ for four drives on one WWW site but I cannot remember where. I was looking at getting two of these for my new box and using Software RAID. Of course I haven't written off a hardware raid solution yet.
