Re: SCSI vs SATA

Tech-Archive recommends: Speed Up your PC by fixing your registry

yep, the 2310 has four internal SATA II connectors, and should allow RAID5
on these ports.
the 2312 has two internal and 2 external, and as long as the two(or at least
one) externals are connected appears to do RAID5 on mixed channels.
the 2314 has only external channels.

Use a 2310 for your RAID5 array (3+hotspare) and use another card for your
backup device.

I'm looking at installing a SATA RAID controller on my server SBS03R2 to
replace the on board SATA controller. I don't want to use software raid.

Controller Specs:
HighPoint RocketRAID 2312
PCI-e x1 (x4, x8 and x16 slot compatible ) interface
2 eSATA II ports at 300 MB/s per port
Up to 2 SATA II or SATA I Hard Drives
Support RAID 0, 1, 5, 10 and JBOD
Support Windows, Linux, FreeBSD and Mac OS X
64bit LBA for RAID arrays greater than 2TB

Also using an external eSATA drive for backup with the 300 MB's transfer
rate verses the USB2 rate.

U320 SCSI vs SATA cost factor.

Anyone have any experience with a SATA Raid controller and have any feed
back or recommendations?

I went through the installation, RAID initialization, formatting, and
OS installation for a mirror array using the RocketRaid 2320. I had
one problem during the course of all of that, but once I finished
installing Windows (Small Business Server 2003 Release 1 in this case)
it worked like a charm. Haven't had any problems yet, and it's been
nearly a year.

Anyways the problem I had was that the supplied driver (the one you
hit F6 for when booting to Windows setup) was not recognized by setup.
I tried the included floppy disk, and later I created a floppy from
the included driver CD. Neither was producing any results. I then
proceeded to download the latest driver from their website, as well as
downloading and installing the latest "BIOS" revision (I would call it
firmware, but Highpoint doesn't). One of those two items solved my
problem and allowed me to proceed. Kind of nerve racking when staring
at the cost of my client's server and the date of delivery I had
agreed to. =/ But it worked.

By the way, I haven't looked at the 2312, but "Up to 2 Hard Drives"
doesn't exactly scream RAID 5 support. =]

Hope that helps!
