Should you buy the Asustor Lockerstor 4 Gen2?
Fill all 4 bays in RAID 5 and you keep 75% of the raw space, losing one drive's worth to parity. It's an Intel Celeron N5105 in there, for the record.
No 10GbE out of the box, but the PCIe slot will take a card later. The four M.2 slots take NVMe drives for a cache or a small fast pool, and you can grow it to 12 bays with Asustor's expansion units.
Usable space with 4 matching drives
These are decimal TB, the way drive boxes count them, and Windows will show roughly 9% less. Got a mix of sizes? Put your own drives in the calculator and it'll work out the layers.
