Agreed, two RAID 6 arrays joined in a storage pool. However, if you put a gun to my head, I'd say RAID 6. Btw, put up a poll. :p

References? :)

Agreed, since the cost of manufacturer is no cheaper. However, since the cost of manufacture is no cheaper, if the profit margin is high enough (obviously lower capacity drives of the same class have to be sold at an appropriate price), then likely they can justify it.

Well first of all, I made a huge n00b error by talking about parity disks in RAID 6 when I KNEW that the parity is woven among all of the disks. But yeah, you are on the right track. Kind of like RAID 6+1, but not, if you know what I mean? :p

Many thanks for the replies. It seems there are at least three factors in play here: 1) Number of drives in the array. The more drives in the array, the more chance of one failing. 2) The size of each drive. The larger capacity each unit is, the longer the rebuild time will be and hence the...

This for all those girls and boys who run large arrays, in terms of number of drives. At what point do you stop making your RAID 6 array any bigger? I know with RAID 5, it's around 7-8 drives, and at that point you start looking at RAID 6. But what about RAID 6? How many drives is a...

Samsung F3s hit 140MB/sec with two 500GB platters. I doubt WD are putting 2x 500GB platters in a 640GB drive, however they could be putting either a) single 667GB platter shortened in firmware to 640GB b) two 320GB platters which have the areal density of the 500GB platters, but are...

:eek: Now that would be nice, but can you imagine how many file systems they'd have to be aware of? NTFS, ext4, UFS, HFS and its variants, JFS, XFS, btrfs...

@OP Before you clone it, try running SpinRite 6.0 over it. It's pretty good at stabilising a dying disk drive. I can personally attest to it.

That's guy's a bit of a scaremonger to be honest. He may have a point with consumer drives, but the article is sensationalised to a certain degree. However, there are still a few outfits that won't go past 500GB/drive in an array (even with enterprise drives), simply to reduce the failure...

To add to this, a full blown hardware RAID card will have local ECC memory, and a battery backup unit to guard against data corruption in the event of a power failure. A system such as the one you describe will use ECC memory (I'm guessing the CPU is a Xeon) and you can achieve redundant power...

Going by what you have said so far, this looks like it will be your own personal server. With that in mind, there is no real need to invest in RAID Edition or "enterprise class" hard drives. Your server is not mission critical. Another thing to watch is that Western Digital RAID Edition drives...

Thermaltake Toughpower 850W. Got it back in 2007, and unless something goes badly wrong, it'll power a few builds to come.

Easily the 700MHz Pentium IIIs. They overclocked well, you could pair them up without paying through the nose, and the ABIT VP6 was the all-time best board to stick them on. Best processor(s) I ever owned. Quick edit: those 700MHz PIII were monsters, I took them up to 1001MHz on Golden Orbs.

hmmm... Pentium II @ 450Mhz in a Gateway pre-built. Dual Pentium III @ 1GHz on an ABIT VP6 Dual Pentium IV Xeons @ 3.06GHz on an ASUS PC-DL Deluxe Core i3 530 @ 2.93GHz on a Gigabyte GA-H55M-d2H
