August 15, 20241 yr Hey Folks! I'm configuring a QNAP TVS-h874 + TL-D800S for a total of 16 18TB drives. The 800S expansion unit connects to the 874 using a 2-port SATA 6Gb/s pcie card. Each port controls 4 of the disk drives on 800S. I intend to create an array using all 16 disk (2 of them for parity). My question is - where should I place the parity drives to optimize performance? I've numbered the bays in the image below.
