Model DS1525+

Should you buy the Synology DS1525+?

Run SHR across the 5 bays and 80% of the raw space is yours to fill. Or go SHR-2 for two-drive protection and still keep 60%, which is where we'd lean once the drives are 16 TB or bigger and a rebuild takes the best part of a day. Inside is an AMD Ryzen V1500B. It's x86, and Docker's happy. RAM goes up to 32 GB (ECC included), which is plenty for a couple of VMs as well as the usual containers.

No 10GbE out of the box, but the PCIe slot will take a card later. The two M.2 slots take NVMe drives for a cache or a small fast pool, and you can grow it to 15 bays with Synology's expansion units.

Usable space with 5 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.
