I love the CableDeconn bunched SATA data cables; they're definitely the only way to fly, assuming lack of SATA backplanes. We end up with 4x 3.5 drives in the bay, 10x 3.5 drives in CaseLabs cages in the PSU side, 3x M.2 devices in the motherboard PCIe 4.0 slots, and 2x M.2 devices in the HyperX card. This leaves room for 2 more M.2s in the card, and 4x 2.5 devices in the smaller bay. The bottom 2 slots in the bottom hard drive cage are blocked by the PSU-side radiator; indeed, I had to take a hacksaw to said cage to get it into the machine. | |||
See my analysis of [[13_drives|how to best make use of 14 drives]]. I went with a striped raid2z for my 14 Exos drives (also known as a RAID60 in the Old English), yielding 180TB usable from 252TB total. I suffer data loss if I lose any combination of 4 drives, and can lose data if I lose certain combinations of 3 drives (any combination where all three lost drives are in the same raid2z), but no rebuild ever involves more than seven drives. | |||
