Hi,
right now I have the following configuration:
zbackup is occupied by bacula and out of scope here.
zroot contains all sort of filesystems for the base system and the jails.
zusers contains filesystems for my and my wifes personal data.
Each disk of zroot and zusers is 1TB of size.
zroot:
- SAMSUNG Spinpoint F3R (HE103SJ), 1TB, 32MB, SATA-2, 7.1W R/W, 6.2W Idle
- SAMSUNG Spinpoint F2 EcoGreen (HD103SI), 1TB, 32MB, SATA-2, 5.6W R/W, 4.4W Idle (replacement for a failed F3R in May 2018)
zusers:
- WD Caviar Green (WD10EADS), 1TB, 32MB, SATA-2, 5.4W R/W, 2.8W Idle
- WD Caviar Green (WD10EADS), 1TB, 32MB, SATA-2, 5.4W R/W, 2.8W Idle
- WD Caviar Green (WD10EADS), 1TB, 32MB, SATA-2, 5.4W R/W, 2.8W Idle
- WD Caviar Green (WD10EADS), 1TB, 32MB, SATA-2, 5.4W R/W, 2.8W Idle
The zusers disks are now 9 years old (SMART spinup time: 8.5 years).
The zroot disks are 7 years old and one already failed in May.
I'm now considering replacing all the 6 disks by one RAIDZ configuration. I fear more harddisk loses in the future because of the age of the drives.
I'm not sure what configuration I should go for.....
- I don't need much more overall disk capacity, but who knows what comes in the future. Given the time I plan to use the new disks I want at least to double the available cappacity.
- Performance is also not the top priority. All they need to achive is saturating 1Gbit network transfer rates in write and read.
- I'm taking power consumptions under consideration as the system runs 24/7.
My plans:
- RAIDZ1 with 3 disks each 4 TB of size: Western Digital WD Red 4TB, 3.5", SATA 6Gb/s (WD40EFRX) which would give me: 8TB disk capacity at a cost of ~350,-€ and a r/w power consumption of 13,5W
- RAIDZ2 with 5 disks each 3 TB of size: Western Digital WD Red 3TB, 3.5", SATA 6Gb/s (WD30EFRX) which would give me: 9TB disk capacity at a cost of ~460,-€ and a r/w power consumption of 20,5W
- Power consumption difference would mean 15-20€ more to pay each year for the RAIDZ2 configuration
- The RAIDZ2 configuration is 110,-€ more expensive
+ The RAIDZ2 configuration would allow two drive failures at the same time.
Given the fact that in the past 9 years only 1 out of 6 harddisks failed I'm tending to go again for RAIDZ1 and not for RAIDZ2 even if it might be more secure.....
What would you go for? Or would you choose something completly different? Any proposals?
Best Regards,
Oliver
