<div lang="EN-US" link="blue" vlink="purple"><div></div></div></blockquote><div><br></div><div>Like many others have said already, I also feel that using a RAID array for recordings is not necessary. I do, however, have my OS and Database on my root disk, which is a Raid-1 mirrored 200GB SATA disks.</div>
<div><br></div><div>I use 6 SATA drives for video storage, sdc through sdh, 5 of which are 500GB, and one is 1TB. (All were 500GB initially, but one got replaced with a 1TB drive before it failed completely...)</div><div>
<br></div><div>I had initially setup this system with 6x500GB drives in a software Raid 5 configuration, but after a dual HDD failure and losing *every* recording a year or so ago, I switched to Storage groups. Granted, a dual HDD failure *should* be rare, but at least if two drives were to fail now, I'd only lose 1/3 of my recordings instead of all of them. (This is just TV after all!)</div>
<div><br></div><div>So I'd just Raid the OS and Database disk, and run individual disks for the Video/Recordings disks. </div><div><br></div><div>Anyways, just my 2 cents... </div><div> </div><div>J-e-f-f-A</div></div>
