| 1- can SATA and IDE coexist if set up as SATA for C: and IDE for CDROM and
| other hard drives?
Yes, if the mobo supports it. What hardware components do you now have?
| 2- Can 2 SATA drives be set up as RAID0 and will there be a peformance
| increase over a single SATA or IDE drive?
Yes, if you run applications that can benefit from RAID0, like photo- or
video-editing software. Otherwise, using a fast single drive you may not
notice much difference.
I run two 36gb Raptors in RAID0 as C:, a 160gb Maxtor for D:, and rotate six
drives (mostly WD) in mobil racks for cloning with Norton Ghost. If I
didn't do photo editing and had a friend not given me a second Raptor drive
to incorporate into RAID0, I probably would still be running an all
single-drive system.
| 3-Western drives are advertises as regular and Caviar drives. Is there a
| difference with the caviar drives if both have the same specs?
Most EIDE and SATA drives are Caviars, with the exception of the Raptors
(10k rpm Enterprise drives) and a lower-performance Protege series. The
latter run at 5400 rpm but may be as reliable as the faster Caviars, which
operate at 7200 rpm, or perhaps even better.
For best performance outside the Enterprise series (Raptors), look for 7200
rpm drives with 8mb buffers.
| 4-which western digital drives are suggested if not wanting the 10K
drives?
Pick the size you need within the 7200-rpm, 8mb-buffer group for
performance, SATA or IDE. SATA and PATA (IDE) are very close in performance
for most applications and you can pick up some bargains for the latter if
you look around (e.g.
www.dealnews.com). The 5400-rpm drives will not
dazzle you with their speed, but may be quieter and run cooler.
