Why it fits

  • 2 SATA drive bays and 0 M.2 slots
  • 2.5GbE fastest included network port
  • 4GB supplied RAM, expandable to 16GB

Know the trade-offs

  • Two SATA bays leave no room to add a third data drive to the same chassis.

Why it fits

  • 4 SATA drive bays and 0 M.2 slots
  • 2.5GbE fastest included network port
  • 4GB supplied RAM, expandable to 16GB

Know the trade-offs

  • The single network port tops out at 2.5GbE.

Best fit forTwo hard drives plus a separate SSD workspace

Why it fits

  • 2 SATA drive bays and 3 M.2 slots
  • 5GbE fastest included network port
  • 8GB supplied RAM, expandable to 32GB

Why it fits

  • Eight SATA bays and two M.2 NVMe slots
  • Two native 10GbE RJ45 ports and two Thunderbolt 4 ports
  • 8 GB DDR5 supplied, with 64 GB maximum memory

Know the trade-offs

  • 4 GB DDR4 ECC supplied, with 32 GB maximum memory
  • One 2.5GbE port plus one Gigabit Ethernet port

Know the trade-offs

Best fit forAn eight-drive DSM archive with optional faster networking and separate DX525 expansion units

Why it fits

  • Eight SATA bays and two M.2 NVMe slots
  • 8 GB DDR4 ECC supplied, with 32 GB maximum memory
  • Two native 2.5GbE ports plus a PCIe Gen3 x8 slot with x4 link

Know the trade-offs

ASUSTOR, AS6704T v2

Lockerstor 4 Gen2+ AS6704T v2

Keep a hard-drive archive and a separate SSD workspace in a four-bay body, with native 5GbE for a suitably equipped desk. Decide on the network upgrade before filling the SSD slots because the optional 10GbE card replaces their board.

Best fit forA four-drive home archive and SSD workspace on a 2.5GbE or 5GbE network

Why it fits

  • Four SATA bays and four M.2 2280 NVMe slots, PCIe 3.0 x1 per M.2 slot.
  • Two native 5GbE ports, with 2.5GbE and 1GbE compatibility.
  • Intel Celeron N5105, 4GB DDR4 supplied and 16GB maximum.

Know the trade-offs

  • Installing the optional 10GbE card requires removing the M.2 daughterboard. Four internal NVMe drives and that upgrade cannot coexist.
  • 4GB RAM supplied, 16GB maximum. Storage capacity does not determine how many applications can run comfortably.
Position 30
ASUSTOR Lockerstor 6 Gen2+ AS6706T v2

ASUSTOR, AS6706T v2

Lockerstor 6 Gen2+ AS6706T v2

Leave room beside a four-drive archive for a removable MyArchive backup, or grow the main array beyond four disks. The wider enclosure buys drive positions, while its network ports and processor match the four-bay Gen2+.

Best fit forA growing family or work archive with spare internal drive positions

Why it fits

  • Six SATA bays and four M.2 2280 NVMe slots, PCIe 3.0 x1 per slot.
  • Two native 5GbE ports and Intel Celeron N5105.
  • 8GB DDR4 supplied, 16GB maximum.

Know the trade-offs

  • A six-drive main array fills every SATA bay. Reserve a bay from the start if you want a removable MyArchive disk.
  • The optional 10GbE card requires removing the M.2 daughterboard, so it displaces all four built-in NVMe slots.
Position 31
ASUSTOR Lockerstor 4 Gen3 AS6804T

ASUSTOR, AS6804T

Lockerstor 4 Gen3 AS6804T

Use native 10GbE without giving up the four NVMe positions beside your hard-drive archive. USB4 supports compatible external storage, but it will not turn the NAS into a directly attached USB4 drive for your laptop.

Best fit forA 10GbE editing desk that also needs a separate internal SSD layout

Why it fits

  • Four SATA bays and four M.2 2280 NVMe slots, PCIe 4.0 x1 per slot.
  • Two native 10GbE ports plus two 5GbE ports.
  • AMD Ryzen V3C14, 16GB ECC DDR5 supplied and 64GB maximum.

Know the trade-offs

  • USB4 does not provide a direct host-to-host connection to a Mac or PC. Plan an Ethernet connection.
  • No HDMI output. Verify your intended media application rather than treating the Ryzen processor as a universal media upgrade.
Position 32
ASUSTOR Lockerstor 6 Gen3 AS6806T

ASUSTOR, AS6806T

Lockerstor 6 Gen3 AS6806T

Keep the same native 10GbE and four-NVMe layout as the four-bay Gen3, with two more SATA positions for archive growth or a planned removable backup. Those extra bays do not upgrade the processor or memory ceiling.

Best fit forA six-drive archive or a four-drive array with room for removable backups

Why it fits

  • Six SATA bays and four M.2 2280 NVMe slots, PCIe 4.0 x1 per slot.
  • Two native 10GbE ports plus two 5GbE ports.
  • AMD Ryzen V3C14, 16GB ECC DDR5 supplied and 64GB maximum.

Know the trade-offs

  • 233 mm wide, compared with 170 mm for the four-bay Gen3. Allow ventilation and access beyond the body dimensions.
  • USB4 does not connect directly to a Mac or PC as host-to-host storage. No HDMI output.

The choices that matter

How to choose your next NAS device

Focus on the factors that change which product works best for you.

01

Plan usable space, not raw capacity

Drive protection consumes bays. File-system overhead and snapshots also reduce the space available to files.

02

Choose the drive count before the processor

A processor upgrade cannot add a missing bay. Start with the storage layout and expected growth.

03

Plex changes the processor question

Direct play is easy. Live video conversion can require supported hardware transcoding or a separate media computer.

04

Network speed needs an end-to-end path

A faster NAS port helps only when the switch, cabling and client can use it.

05

Camera recording has its own limits

Count included licenses, supported cameras, retention space and the maker channel ceiling.

06

Keep another copy

A NAS protects availability. It does not replace an offline or off-site backup.

Direct decisions

Compare the choices people actually face

Compare popular choices or start with a need-specific shortlist.
