The catch
ASUSTOR Lockerstor 4 Gen3 AS6804T
Four array disks leave no SATA bay for MyArchive. Plan the separate backup route before filling the enclosure.
Side by side
ASUSTOR AS6804T vs AS6806T: Six bays mean more archive room, with no change to the memory ceiling
Quick verdict
Go with the AS6806T when your main archive needs more than four SATA disks, or when four array disks have to leave a bay free for a removable MyArchive copy. The AS6804T works if four disks are enough and the backup is stored elsewhere. It is 63 mm narrower, and it has the same Ryzen V3C14, 16GB ECC, 64GB memory ceiling and native dual 10GbE.
Before you buy
Why, and what it costs you
A spare bay can keep the off-site copy in the weekly routine
If Sunday backup means taking a finished copy to another location, AS6806T can keep four disks in the main RAID 6 array and use a fifth for MyArchive. AS6804T needs a different layout or an external backup route. The extra position is useful only if you reserve it and then complete, eject and store that copy.
Where this comes from
Six physical SATA bays minus four array members leaves two available positions. Four minus four leaves none. MyArchive requires an available bay and an independently configured disk with sufficient backup capacity.
The catch
ASUSTOR Lockerstor 6 Gen3 AS6806T
The larger box does not add CPU cores, supplied RAM, NVMe positions or a higher RAM ceiling over AS6804T.
ASUSTOR Lockerstor 4 Gen3 AS6804T
- Why pick it
- The archive fits on four SATA drives, and your independent backup goes to external or remote storage.
- You want the Gen3 networking and memory platform, packed into the narrower 170 mm body.
- The catch
- Four array disks leave no SATA bay for MyArchive. Plan the separate backup route before filling the enclosure.
ASUSTOR Lockerstor 6 Gen3 AS6806T
- Why pick it
- A removable MyArchive disk has to sit alongside four SATA array disks.
- Your online archive needs five or six SATA disks, and you want to avoid replacing the enclosure.
- The catch
- The larger box does not add CPU cores, supplied RAM, NVMe positions or a higher RAM ceiling over AS6804T.

What this page compares
Four-bay and six-bay Lockerstor Gen3 models, weighed for growing photo archives, removable backups and shared workspaces. Find out what the bigger enclosure really gives you.
Both Gen3 models offer the same processor, supplied memory and network connections. The credible upgrade is about the drive layout and space it occupies, rather than a blanket faster-NAS claim.

Differences you will notice

AS6804T needs a different layout or an external backup route. The extra position is useful only if you reserve it and then complete, eject and store that copy.
How we worked this out
Six physical SATA bays minus four array members leaves two available positions. Four minus four leaves none. MyArchive requires an available bay and an independently configured disk with sufficient backup capacity.
More hard-drive room does not fix a crowded application budget
A household running shared files, photo indexing and personal server applications gets the same 16GB supplied RAM and 64GB supported maximum from either model. If application memory is the problem, choose the narrower AS6804T and budget the appropriate RAM rather than buying two unused SATA bays. CPU load and software support still need separate checks.
How we worked this out
Both use V3C14, 16GB ECC supplied and 64GB maximum. This identifies unchanged hardware limits. It does not show identical measured app performance. The required compatible memory is an additional purchase.
The wider box earns its space only if the disks do
For a home office that doubles as a guest room, AS6804T leaves 63 mm more shelf width while retaining four NVMe positions and dual 10GbE. AS6806T becomes worthwhile when extra SATA capacity is the actual requirement. With equal 8TB drives, six-drive RAID 6 gives 32TB before overhead versus 16TB from four drives, but it also fills all six bays.
How we worked this out
Width delta 233 minus 170 = 63 mm, about 2.5 inches. Nominal RAID 6 calculation (N minus 2) x 8TB. Required ventilation, cables, system overhead and separate backup space remain outside these figures.

Trade-offs
What each pick costs you
With ASUSTOR Lockerstor 4 Gen3 AS6804T
- Both are sold diskless. Before ordering, confirm the exact model suffix, the RAM supplied, the seller, the return terms and whether the unit qualifies for US warranty. Drives, optional cards and memory upgrades all cost extra.
With ASUSTOR Lockerstor 6 Gen3 AS6806T
- The extra bays ship empty. Extra array disks, removable backup disks and compatible ECC memory are separate purchases.
Change of plan
When the answer changes
A four-drive array and removable internal backup must coexist
Go with ASUSTOR Lockerstor 6 Gen3 AS6806T. Two additional SATA positions make the layout possible.
Four drives cover capacity and backup is already external
Go with ASUSTOR Lockerstor 4 Gen3 AS6804T. Keep the same core platform in the narrower body.
The purchase is meant to raise the supported RAM ceiling above 64GB
Neither model fits. Neither model changes that limit.
Decision guide
Before you buy
You need space to keep family originals and work projects without the sole backup bay being converted into more live storage.
What this page can’t tell you
- These MyArchive scenarios rely on a planned SATA array and a separately set-up spare bay. Never take a drive out of a running array to use it as a removable archive.
- RAID, snapshots and ECC are not backups. Hold a tested copy somewhere other than the NAS, shielded from the same accident or account compromise.
- Ethernet figures here describe link rates and say nothing measured about file-transfer speed. Client adapters, switches, cabling, disks, file sizes and simultaneous work can each become the bottleneck.
- The page gives neither model a measured edge in noise, power or reliability.
