Hi people,

I am about to upgrade my Dell PII 400, to a no name Athlon I guess (P4 just not there yet...).

from years of working both on Mac and PC's I know that it doesn't matter what processor you have, it's the HD speed and interface that counts. and I have been using SCSI for that reason.

now I am thinking of the RAID option which seems cheaper and easier to handle.

does anyone know if it's reliable ? where can I get information on this topic ? I will use it for work as a multimedia/ wed designer and I don't want to lose data.

thanks,

Mic
 
Here's a place to get some info on RAID.

RAID is a system of organizing multiple HD's in such a way that either increases data performance, or reliability.

The simplest form of RAID that enhances reliability is RAID-1 ("mirroring&quot😉. This is where two hard disks are written to simultaneously. So if one HD dies, the other contains an exact copy of the lost data.

Read the link for more info on other (more complicated & expensive) forms of RAID which enhance reliability.

The cheapest form of entry-level RAID-1 will require two identical IDE hard disks, and either a hardware or software controller to "mirror" the data to both of the drives.


Some tips:

When possible, try to get a MATCHED SET of hard disks for any RAID use.

When possible, stick with hardware-based (via motherboard or PCI card) RAID, rather than a software-based RAID. Since you mentioned that you are upgrading, all you need to do is look for a motherboard with built-in RAID support.

RAID is now possible with both SCSI and IDE hard drives! I recommend using IDE unless the highest performance is needed, in which case you probably want to go with SCSI.

Good luck!
 
if it's important for you not to lose data, then i recommend sticking with scsi, but im not sure how safe raid is
if you have a problem with one of the drives (raid 0 requires at least 2 drives), you won't have backup (as both drives would lose teh data), but im pretty sure you wouldn't have any more problems than a normal drive.
 
"...raid 0 requires at least 2 drives..."

Raid-0 increases performance , not reliability.

"...I will use it for work as a multimedia/ wed designer and I don't want to lose data..."
 
Look up hardware IDE RAID controllers, like the Escalade. RAID 5 is the only reason to bother with IDE RAID, and it's not much better than a single SCSI disk.
