2023年12月13日 · Determine the usable capacity and other metrics of a ZFS storage pool and compare layouts including stripe, mirror, RAIDZ1, RAIDZ2, RAIDZ3, and dRAID. Total Disks in Pool: Add Disk (TB):

2023年12月21日 · The largest number of drives for my NAS rig as currently planned is a total of 5 disks and I would like the protection of raidz2. This is the limit for two reasons: The case I want badly can only support 5 disks without modding, and …

2011年6月7日 · So RAIDZ2 gives you an additional level of protection by having another safety net of 2 drive failure. With such large capacity drives, there is a larger chance of more bits going bad quicker and the pain in restoring large amounts of data and the relative cheap price of 2tb storage I would strongly urge RAIDZ2.

2019年9月11日 · Option 1 - RAIDZ2 2 Vdevs of 10 x 4TB drives each - assumed con : - to increase space i mite need 10 more drives to add another vdev Option 2 - RAIDZ1 4 vdevs of 5 drives each: - in this i can expand storage with another vdev of 5 drives Both options will have 4 parity drives so i guess reliability should be same

2016年6月12日 · Yes, RaidZ2 can withstand two drives being lost (but then you are at the "edge of a cliff" if you don't get that addressed). So say you setup 3-way mirrors, in that sense you have the similar redundancy as RaidZ2; however you are using 2 of the drives for redundancy and only getting one drives worth of usable space...

2022年1月21日 · I currently have a RAIDZ2 volume with 4x 6TB drives. My setup serves principally as our Plex server with movies, pictures, home videos, and music. We do also use it as a backup machine for some of the other computers in the home. However, most of its workload is devoted to streaming Blu-Rays (which only demands at most 4 MBs per second).

2021年12月4日 · It talks about RaidZ1 + Spare vs RaidZ2 but the reality is the same when comparing RaidZ2 + Spare vs RaidZ-3. The more drives you have in a vDev, the less flexibility you have. The more vDev you have, the more performance you get. As such, to put too many drives in a single vDev will not be as beneficial as having more vDevs with fewer disks each.

2021年6月5日 · RaidZ2 otoh provides more resilience (any 2 disks can break) and in the case of 6 disks, 67% space efficiency (vs 50%). Performance should also be more than enough for nextcloud and plex. There are very strong cases for pools …

2018年10月2日 · RAIDZ2 and Z3 add two and three sectors per stripe, and can recover from two and three drive failures per vdev, respectively. For RAIDZ performance, the terms parity disks and data disks refer to the parity level (1 for Z1, 2 for Z2, and 3 for Z3; we’ll call the parity level p ) and vdev width (the number of disks in the vdev, which we’ll ...
