pc storage

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

Current storage situation

I store all data to ZFS on Linux since version 0.6.2. Recently ZFS on Linux (0.8.6) was integrated in OpenZFS 2.0 sharing sourcecode with FreeBSD and Illumos the opensource version of Solaris where ZFS was first developed under Sun Microsystems. The previous LVM raid 0 volumes have been moved to ZFS pools with RAIDZ1 or RAIDZ2.
RAIDZ1 is like RAID5 and can withstand 1 disk breaking. RAIDZ2 can withstand 2 disks breaking. But after disk failure recovery is only needed for the data, not the entire disk so it is much quicker than plain RAID5 or RAID6.
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/RAIDZ takes about 5% of the volume size for additional overhead.
Currently the 10x2T are retired and the healthy ones were sold.
I have 12x3T in raidz2, integrated in my linux desktop PC.
In Nas1 there are 14x4T in RAIDZ2 plus another 14x4T in RAIDZ2. So 2 pools with 1 vdev each.
In Nas2 I have 12x8T in RAIDZ2.
The always on XeonD server has 5x 2TB SSD in RAIDZ1. (1TB replaced with 2TB 2025-09)
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 were pending failure. No data was lost.
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 separate 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+. It is managed via IPMI (Supermicro).
The XeonD has 6 sata interfaces. 1x boot plus 5x data. It has onboard 10Gbe RJ45. It also has IPMI (Supermicro) for management.
The Linux desktop PC has 6 sata interfaces, a M2 interface and a Highpoint HBA card with 8x sata (2x SF8087). Currently 1x sata is used to boot the SSD, 4x sata for disks and 8x sata from the HBA Card to connect in total 12x 3TB disks in a RAIDZ2 ZFS pool.
I am planning to replace 12x3T RAIDZ2 with 6x 18TB RAIDZ1 and to replace the sata boot SSD with a M2 variant. Then the HBA card is not needed anymore and a 10Gbe network card can fit in its place.
