| 1232889 | 2011-09-22 20:00:00 | Ok so after all your comments and further reading I've decided RAID 5 doesn't belong in a home desktop enviroment, at least for me. In fact it seems RAID in general is more trouble than it's worth so what I really need is a backup device that can handle approx 4TB of data, any suggestions? the fall back plan is 2 x 2TB external USB 3 drives but I'd prefer something tidier, building a cheap NAS starts to seem like a good option. Thanks Alex those links were informative, and led to another about why Home RAID is a bad idea in general. |

| 1232891 | 2011-09-23 00:10:00 | Actually that link indicates both RAID 0 and RAID 1 is supported, which leads to the question what about RAID 10? which is a combination of the 2 4 x WD green in RAID 10 would = 4TB @ approx $550 (actually less, I would find a way to re-use my existing 2 somehow) 3 x WD RE in RAID 5 = 4TB @ approx $900 granted the RE drives are undoubtedly better but we are not talking about enterprise use with critical data here. Also the RAID10 has more redundancy built in to counter the cheaper drives. Psycik's comments about the motherboard have me rethinking any type of internal RAID array, a NAS, server, or external RAID enclosure seems smarter. Did you read this bit... RAID-specific, time-limited error recovery (TLER) Green are the worst drives for this as they have power management in the firmware to spin down, this is where the TLER comes in......For $50 difference between the drives, I know which I would rather have....but its your data |

| 1232892 | 2011-09-23 00:25:00 | www.computerlounge.co.nz www.computerlounge.co.nz thats $170 difference per drive so a little more than $50. Probably worth it for mission critical enterprise applications but totally unjustified for home use. You could buy 2 drives and use one as offsite backup for less than the price of 1 raid edition drive. If you were referring to the blue or black drives then sure, but they dont support RAID any better than green as far as I can tell. Anyway I've given up on the Idea as not worthwhile in a home enviroment, will now look into ext hard drives or a NAS/Home server and work with regular backups. It didn't take much reading to convince me it's abetter solution than RAID and a hell of a lot cheaper. When you think about it RAID only protects you from a drive failure, whereas a seperate backup drive also protects you from virus/ malware/ data corruption/ theft/etc, etc. I just liked the Idea of a low maintenace permanent solution with increased data security and no need to connect a backup device, but not at the price it turns out it will cost. |

| 1232893 | 2011-09-23 00:31:00 | I stand corrected. One thing with Raid 5, I wouldn't use less than 4 drives......and really in an enterprise environment you would have a hot spare on standby.... Yes, I'll happily second that. We use the RAID5 to export over iSCSI to 3 VMWare boxes. |
