9 or 12 of these

$170 each 1TB with 8GB ssd 64MB cache. layered caching on the drive essentially.

linux

how fast will this be?

is this enough raid for my paranoias of dataloss?

1343075 2013-05-25 01:52:00 will mount them using these
dx.com
and
pricespy.co.nz

i realise raid55 is not a backup so multiple backups are enabled through this

dx.com

cant make the raid too large as a backup will need to be stored on a single drive, they're up to what 3 or 4 TB now?

some rethinking is in order

1343076 2013-05-25 02:04:00 single drive, they're up to what 3 or 4 TB now?

individual 2.5" drives, they're up to what 2TB now?

1343077 2013-05-25 02:11:00 raid 6 would, imo, be a more practical approach for redundancy and space efficiency. inphinity (7274)

i was thinking one of these 2=3 instead of the 3-4 variant

raid55 is more drives of parity, seems more reliable.

would there be any real performance difference between raid 6 and raid55?

is it safe to do this as software raid?

ill be usign several differnt controllers and software seems to be my only option

im building a multi-seat mainframe-like server thing.

this is the main board www.asus.com

1343079 2013-05-25 03:08:00 raid 6 it is then.
8 drives seems most practical

1343080 2013-05-25 03:27:00 seems this idea shall not bear fruit.

SSHD is unsuited to raid

1343081 2013-05-25 03:47:00 is PCI still good enough for raid?

dx.com

1343082 2013-05-25 04:43:00 in the interest of performance, setup and cost i have decided a 3 drive raid5 shall be sufficient.

OS on a 32GB SSD
data on a 2TB raid5 array, backup onto a 3TB removable HDD

intrl.startech.com

this should be sufficient for 4 seats
