Asustor Lockerstor 6 Gen3 (AS6806T): Specs and Total Build Cost
The Lockerstor 6 Gen3 is Asustor's 6-bay AS6806T, the only model in this cluster with a vendor-documented independent M.2 volume stated without any cache-vs-pool ambiguity. Below is what Asustor's own spec page states, what it costs filled with drives today, and its drive-compatibility position.

Asustor's own spec page carries a distinct "M.2 Volume" section, separate from the main-bay RAID section, with its own supported RAID levels (Single, JBOD, RAID 0/1/5/6/10) - explicit, unambiguous confirmation of an independent M.2 storage volume, not cache-only.
The honest total: chassis + drives, three ways
$1770.99 buys the empty chassis. Filling all 6 bays is the real purchase, priced at three genuinely different tiers below.

The smallest cheque that fills all 6 bays, separately from the value tiers above: 6 x Seagate SkyHawk 6TB ST6000VX001 at $313.00 each = $1878.00.
ECC memory and the Ryzen platform
Asustor's own spec page states 16GB of ECC DDR5-4800 SO-DIMM as shipped, expandable to 64GB - ECC memory is confirmed on this model and on Synology's DS-series machines in this cluster; it is documented as absent on the QNAP and TerraMaster machines, and we found no source either way for UGREEN or UniFi. The AMD Ryzen quad-core platform pairs with dual 10GbE and dual 5GbE ports, four network interfaces total across two speed tiers rather than four ports of the same speed.
Drive compatibility, and a genuine gap
Asustor publishes its hard-drive compatibility list by NAS series, not by individual machine - and the binding from the Lockerstor 6 Gen3 specifically to a named series is not published anywhere we could verify. We do not guess that binding; the compatibility page states this gap directly rather than assigning the AS6806T to a series list on our own inference.
109 SATA HDDs in our own catalogue are fit-verified for this class of bay right now (interface, form factor and CMR-confirmed) - our own check, independent of Asustor's series-level list.

Expansion limits and the M.2 reality
Asustor states "Maximum Drive Bays with Expansion Unit: 18" (6 internal + 12 via expansion, by arithmetic) but does not name a specific expansion-unit model on this page.
The M.2 slots on this model carry the least ambiguity of any machine in this cluster: Asustor's own spec table gives the M.2 Volume its own dedicated section with its own RAID-level list, entirely separate from the main-bay RAID section - a genuinely independent storage volume, stated once, without the cache-versus-pool hedging that appears on the QNAP and UGREEN pages in this cluster.
What else it needs
Power protection: at 250W and six spinning drives, see UPS units for a NAS, priced live with output waveform stated on every row. The Lockerstor 6 Gen3's dual 10GbE ports need a matching switch to be worth anything - see 10GbE for a NAS for live prices.
Frequently asked questions
Frequently asked questions
How many drives does the Lockerstor 6 Gen3 take?
6 x 3.5-inch or 2.5-inch SATA bays, per Asustor's own spec page, plus 4 M.2 2280 NVMe slots - Asustor's spec table carries a distinct "M.2 Volume" section separate from the main-bay RAID section.
What's the maximum capacity of the Lockerstor 6 Gen3?
Asustor publishes no explicit per-drive capacity ceiling for this model - only an example configuration (six 18TB drives for a stated maximum raw total), which is not the same as a stated ceiling.
Can I use third-party drives in the Lockerstor 6 Gen3?
Asustor publishes its hard-drive compatibility list by NAS series, not by individual machine, and the binding from this specific model to its series is not published in a way we could independently verify - see the compatibility page for the full explanation of that gap.
Does the Lockerstor 6 Gen3's M.2 slots form an independent volume?
Yes, explicitly and unambiguously per Asustor's own spec page: the M.2 Volume section lists its own supported RAID levels (Single, JBOD, RAID 0, 1, 5, 6, 10) separate from the main-bay RAID section - a genuine independent storage volume, not cache-only.
What does a complete Lockerstor 6 Gen3 build cost?
$1770.99 for the chassis alone; $2799.24 filled with 6 best-value drives, or as little as $1878.00 for the smallest qualifying set.
Does the Lockerstor 6 Gen3 have ECC memory?
Yes - Asustor's own spec page states 16GB of ECC DDR5-4800 SO-DIMM as shipped, expandable to 64GB.
