Computer Storage

I mainly use the harddisks in the PCs I run for storage of Hidef movies and TV series.

I store all data to ZFS on Linux. All previous LVM raid 0 volumes have been moved to ZFS pools with RAIDZ2.
RAIDZ1 is like RAID5 but after disk failure recovery is only needed for the data, not the entire disk so it is much quicker than plain RAID5. ZFS keeps checksums on all data to ensure data integrity at all times. For RAIDZ1 there is the space of 1 spare disk, for RAIDZ2 (like RAID6) the space of 2 spare disks is needed and used for CRC data and other ZFS overhead data. Besides that ZFS takes about 5% of the volume size for as additional overhead.
Currently there are 10x2T as spare disks. In the linux desktop I have 12x3T in raidz2. In nas1 there are 14x4T in RAIDZ2 plus another 14x4T in RAIDZ2. In nas2 I have 12x8T in RAIDZ2. The new always on xeonD server has 5x 1TB SSD in RAIDZ1. I keep separate pools in order to be able to swap them out to different PC's. I have removed the 10x2T because 2 disks were failing and 3 more are pending failure.
The main NAS PC has 8 onboard sata interfaces and 24 extra sata interfaces through a sas card, there are 24 regular bays (2x10 + one 4in3 bay) and I have stacked 1 seperate 4 drive bay inside the case. Currently 28 bays are in use. The free PCI-E 4x slot is now used for a 10Gbe Intel X520-DA1 network card with SFP+.
The second NAS PC has 14 onboard sata interfaces, 1x for boot 12x in use for the data disks, 1x free sata. It has a 10Gbe Intel X520-DA2 network card with SFP+.
The XeonD has 6 sata interfaces. 1x boot plus 5x data. It has onboard 10Gbe RJ45.
