Greetings,
I currently have the following set up with UnRaid 6.10.3;
Parity WDC_WD121KFBX-68EF5N0_5QK0K9KB - 12 TB (sdi)
Disk 1 TOSHIBA_HDWG11A_Z1L0A021FBDG - 10 TB (sdl)
Disk 2 WDC_WD102KFBX-68M95N0_VCKR49BP - 10 TB (sdj)
Disk 3 WDC_WD102KFBX-68M95N0_VCKW15MP - 10 TB (sdk)
During parity checks or certain other operations, the read/write values average around 230mb/s. Parity checks take around 18 hours to complete with an average of 180mb/s according to the history.
I purchased two 12tb drives. (Western Digital 12TB WD Red Plus NAS Internal Hard Drive HDD - 7200 RPM, SATA 6 GB/s, CMR, 512 MB Cache, 3.5" - WD120EFBX)
I pre-cleared one and added it to the raid. The other I use as to backup data. Once added the parity check took 30+ hours with an average of 114mb/s.
So my question would be does it take longer the more drives you add? Is this type of performance change expected?
I appreciate any feedback anybody has.
Thanks.
