ASUSTOR AS6804T vs AS6806T: Six bays add archive room, the memory ceiling stays the same
The short answer
Choose AS6806T if the main archive needs more than four SATA disks, or if four array disks must leave a bay for a removable MyArchive copy. Choose AS6804T when four disks suffice and the backup lives elsewhere. It is 63 mm narrower and keeps the same Ryzen V3C14, 16GB ECC, 64GB memory ceiling and native dual 10GbE.
Before you choose
The reasoning and the trade-offs
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 actually complete, eject and store that copy.
What this is based on
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.
Main trade-off
ASUSTOR Lockerstor 4 Gen3 AS6804T
Four array disks leave no SATA bay for MyArchive. Plan the separate backup route before filling the enclosure.
Main trade-off
ASUSTOR Lockerstor 6 Gen3 AS6806T
The larger box does not add CPU cores, supplied RAM, NVMe positions or a higher RAM ceiling over AS6804T.

About this comparison
Compare four- and six-bay Lockerstor Gen3 for growing photo archives, removable backups and shared workspaces. See what the larger enclosure actually adds.
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.
Winner by situation
Start with what you need it to do
Four-drive RAID 6 must leave room for a removable copy
AS6806T has two SATA positions left after four array disks. AS6804T has none.

What matters in practice
The differences that matter
01
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 actually complete, eject and store that copy.
How we reached this conclusion
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.
02
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 reached this conclusion
Both use V3C14, 16GB ECC supplied and 64GB maximum. This identifies unchanged hardware limits, not identical measured app performance. The required compatible memory is an additional purchase.
03
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 reached this conclusion
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.

Why it matters
Spare bays after a four-drive array
ASUSTOR Lockerstor 4 Gen3 AS6804TFour SATA bays. Four-drive RAID 6 fills them. MyArchive requires an available bay rather than removing an active array member.
ASUSTOR Lockerstor 6 Gen3 AS6806TSix SATA bays. Four-drive RAID 6 leaves two free SATA positions, one of which can be reserved for MyArchive.
Why it mattersSix bays let the archive and removable-copy workflow coexist. A six-drive array would consume that spare room.

Why it matters63 mm more width buys the two SATA positions. Depth and height stay the same.
Why it mattersA workload limited by memory or application behavior does not gain a higher ceiling from the larger model.

What you give up
Every choice has a cost
If you choose ASUSTOR Lockerstor 4 Gen3 AS6804T
These are diskless configurations. Check the exact model suffix, supplied RAM, seller, return terms and US warranty eligibility before ordering. Drives, optional cards and memory upgrades are separate purchases.
If you choose ASUSTOR Lockerstor 6 Gen3 AS6806T
The extra bays ship empty. Extra array disks, removable backup disks and compatible ECC memory are separate purchases.
Recommendation switch
The decision flips if...
A four-drive array and removable internal backup must coexist
Choose ASUSTOR Lockerstor 6 Gen3 AS6806T. Two additional SATA positions make the layout possible.
Four drives cover capacity and backup is already external
Choose 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
Choose neither. Neither model changes that limit.
What matters in practice
Before you choose
You want room to preserve family originals and work projects without turning the only backup bay into more live storage.
Check these before buying
These are diskless configurations. Check the exact model suffix, supplied RAM, seller, return terms and US warranty eligibility before ordering. Drives, optional cards and memory upgrades are separate purchases.
Allocate every SATA and NVMe position before choosing the enclosure.
Measure ventilation and access space in addition to the closed body.
What this comparison cannot tell you
MyArchive examples assume a planned SATA array and an independently configured spare bay. Never remove a live array member to make a removable archive.
RAID, snapshots and ECC do not replace a separate backup. Keep a tested copy outside the NAS and protect it from the same accident or account compromise.
Ethernet figures are link rates, not measured file-transfer speeds. Client adapters, switches, cabling, disks, file sizes and concurrent work can be the bottleneck.
No measured noise, power or reliability advantage is assigned.
