With 4 drives you can set up a fairly high efficiency array and have a soft failure of any single drive. With some controllers you don't even need to bring the system down to swap out the bad drive. The whole thing is invisible to the OS. SATA hardware itself is hot swap capable. He can't afford to pay his taxes. Do you really think he can afford a $1500 Raid controller? $1500? More like $40 and most SATA controllers support RAID. You may have to pay a little more for RAID 5 but not much My little server is running under RAID. Something called Synology Hybrid RAID (SHR) with data protection of 1 disk fault-tolerance. I'm not sure what the hell that means, actually.  That does sort of look like RAID 5. Is that "backup" drive actually just the conglomerate "wasted" drive in a RAID array? Basically RAID 5 writes "stripes" across all of the drives in the array and the way they are laid out, you have one more drive than the amount of data you can store. When you lose one, the data can be recovered from the stripes on the other drives. You can hot swap out the bad one and the system will restore the array while you work. That sort of sounds like the description I sort of read and sort of understood on the synology site. I think. Oh...the cheapo Seagate drive in my iMac was replaced with an apple-branded drive (shows up as an apple branded drive) that allegedly is a twice the price Hitachi Ultrastar drive that is "enterprise-rated" for servers. That from a fellow on one of the apple forums who had a similar problem and whose drive was replaced by one with the same apple description and model number. If apple updates the iMac substantially this fall or in 2014, I'll sell this one and get the upgrade, especially if it has a large capacity SSD instead of the combo apple now is using in the latest iMacs. I am not sure all of that "enterprise" stuff really means much but Hitachi is a pretty good drive. I still don't really trust any of them. I am also not convinced SSDs last forever. "Cause nothin' lasts forever Like old fords and a natural stone..." |
