After I had yet another Western Digital harddrive die making an 8/11 or 72% failure rate over 5 years, I just ordered parts for a new computer including a hardware RAID from Newegg yesterday.
8x SAMSUNG F1 RAID Class HE103UJ
1x 3ware 9650SE-8LPML
1x 3ware BBU-MODULE-04 Battery Backup Unit
For $1,829.90 to make a 7 drive hardware RAID 6 array with 1 hotspare, but it seems I went with a lot higher quality parts than they did. And I included the price of the controller...
After my horrible experiences with consumer Western Digital drives (6x 250GB PATA and 2x 500GB SATA dead in the last 5 years), I wasn't about to touch these new consumer 2TB "Green" drives or the cursed Seagate 1.5TB drives so I went with the more expensive HE103UJ's. I hope they are worth it since this will be my first experience with a RAID. In the past I just used everything as separate drives since they weren't purchased all at once and I've paid greatly for that mistake.
It's not an ULTRA CHEAP RAID but I think it should be a fairly high quality one at least.
