Welcome to IWETHEY!

New Thank you, everyone!
Really appreciate the input. One other question: what level of RAID protection is best if my goal is to split the drive space for backup purposes? RAID 0,1,5? Still researching....

My thanks,
New RAID is always a compromise.
RAID is always a compromise among cost, redundancy, and speed.

[link|http://www.acnc.com/04_01_00.html|RAID 0] is striping. No redundancy, but higher performance than a single drive.

[link|http://www.acnc.com/04_01_01.html|RAID 1] is mirroring and duplexing. 100% redundancy, but 50% of disks are effectively lost.

[link|http://www.acnc.com/04_01_05.html|RAID 5] is a good compromise of performance and reliability. It has the most complex controller, and requires at least 3 drives to implement.

If you're doing on-line live backups, RAID 1 is a simple choice. You don't have to think about it.

There's a lot more at ACNC.

HTH a bit. Good luck!

New Good info...
My thanks... Seems like RAID 1 is what I need for now. Use RAID 5 at work. Will just buy a bit more storage to compensate. Useful info on the ACNC site. Appreciated!


New Yup, RAID1 is simplest
SATA Disks are so fast and cheap a pair in an enclosure seems to be what you are looking for.


You haven't said the actual amount of space you need though.

New Probably
1TB x 2 (RAID1), if possible... otherwise, can survive with 500GB x 2 (RAID 1) and do multiple configs. My $0.02.

New Oops - thinking of RAID-5
Yes, with RAID-1 you lose half, RAID-5 you lose 1/3.

New Assuming 3 disks
Yup, you lose 1 disk out of however many disks you have in the raid set. As you add disks, you gain speed because you have more spindles, and both streaming reads / writes get faster. But rewrites get dramatically slower as you add disks.

So it really depends on your usage pattern of whether more disks are better or worse for you.

Of course, there are many other variables to think about if you were really pushing for performance.

             Agree...firewire is better than usb2 but both work -NT - (bepatient)
