8-bay NAS systems
These NAS systems list 8 drive bays. More bays raise raw capacity and RAID options, and also raise power, noise, and rebuild time. Bay count is not a performance grade. Use the filters for listed Ethernet class. Check whether you need 2.5 GbE or 10 GbE, and confirm drive interface and size before filling the chassis.

How Many Drive Bays Do You Need in a NAS?
Choose NAS drive bays by starting with usable capacity—not raw disk capacity—and then allowing for RAID, filesystem overhead, free space, backups, and future growth. This guide compares 2-bay, 4-bay, 6-bay, and larger NAS systems.
Read guideHow Much NAS Storage Do I Need?
Calculate the NAS capacity you actually need by accounting for your files, growth, RAID or parity, filesystem overhead, snapshots, and free-space headroom. A worked example shows why raw drive capacity is not the same as usable storage.

RAID
RAID combines multiple drives to improve capacity, performance, or resilience through striping, mirroring, or parity. It is redundancy, not a backup.
Open termCMR
CMR (conventional magnetic recording) stores hard-drive tracks without the overlapping layout used by SMR. It can be a useful recording-technology label when comparing drives for write-heavy workloads.
Open termSMR
SMR (shingled magnetic recording) overlaps data tracks to increase storage density. This can make some random-write workloads and rebuilds more involved than with conventional magnetic recording.
