4-bay network-attached storage compared on official maker specification tables. Every model in this table has four official drive bays, so bay count is not a scored field here. We score official installed system memory, the fastest official onboard Ethernet port, the official CPU core count and the official onboard Ethernet port count. Desktop towers and short-depth rack units share the table; the official form factor is printed on every card. Optional PCIe Ethernet is not scored as onboard speed. A missing scored figure is shown as Not listed and scores at the category minimum.

ASUSTOR LOCKERSTOR 4 Gen3 (AS6804T)
Score 8.4/10 · Check price
Why it wins: 4 official bays, 16 GB official installed memory, 10GbE official onboard Ethernet, 4-core official CPU. Official table lists a 10GbE onboard Ethernet port. Official installed system memory is 16 GB.
"Not listed" means the official manufacturer specification table we used does not publish that figure. Prices show "Check price" until a retailer feed provides a current price.
A NAS is an electrical appliance that holds your files. Use the official power adapter or PSU, keep ventilation clear, and plug it into a surge-protected outlet. RAID is not a backup — keep a separate copy of anything you cannot replace. Change the default administrator password before you put the unit on a network. For rackmount models, use the official rails, get a second person to lift a loaded chassis, and stay inside the rack's load rating. Follow the maker's drive-tray instructions before you remove a disk from an array.

The official specification table also lists TS-432pxu-rp as a related model. Scored hardware figures on the official pages we used are the same; the official difference is a redundant power supply and the published size or weight that goes with it. We keep one product page for this official hardware set so the RP and non-RP listings are not given separate nearly identical pages.

Form factor (official table or official model family)
Installed memory and official expandable memory are different figures
We score the official installed system memory published on the maker's specification table. When the same table lists a higher official maximum capacity, that expandable figure is printed on the product page and labelled as the official maximum. When the official table says the memory is not expandable, we treat that official installed amount as the official maximum and say so. When the official table simply does not list a maximum, we show Not listed rather than assuming the memory is soldered or expandable.
Onboard Ethernet only, not optional PCIe cards
The scored Ethernet speed is the fastest official onboard port on the specification table. If the official table lists a 10GbE or 25GbE port only as an optional PCIe or add-in-card upgrade, that option is not scored as onboard speed. Official port counts likewise include only onboard ports. When we add official port count × official port speed, we label the total computed.
CPU core count is official, not a benchmark
Every 4-bay nas here is scored on the official CPU core count from the maker's table. That figure is consistently published, but a 4-core ARM SoC and a 4-core x86 CPU are not the same product. Read the official CPU model on the card, and do not treat the core count as a lab test or a throughput rating.
Bay count, M.2 slots and safety
SATA or official multi-protocol drive bays are the headline bay count. Official M.2 slots are listed separately unless the official table gives only M.2 slots, in which case we score that official M.2 count and say so. RAID is not a backup. Use the official power adapter, leave ventilation clear, change the default admin password, and follow the maker's drive-tray instructions before you hot-swap a disk.
How this ranking is calculated
Score = weighted average of normalised specs, out of 10. Full method
Installed system memoryOfficial installed system memory published on the maker's specification table. A larger official figure is better for running services alongside file storage. Missing values take the category minimum. Scale: 1 → 16 GB.
28%
Fastest official onboard EthernetFastest official onboard Ethernet port speed on the maker's specification table, in gigabits per second. Optional ports that the official table lists only as PCIe or add-in-card upgrades are not counted. Missing values take the category minimum. Scale: 1 → 10 Gbps.
26%
Official CPU core countOfficial CPU core count published on the maker's specification table. Core count is not a complete performance picture across ARM and x86 designs, but it is a consistently published official figure. Missing values take the category minimum. Scale: 2 → 8.
24%
Official onboard Ethernet portsNumber of official onboard Ethernet ports on the maker's specification table. Missing values take the category minimum. Scale: 1 → 4.
Why are only ASUSTOR, QNAP and Synology models in this 4-bay nas ranking?
These are the official current specification tables we fetched from Synology, QNAP and ASUSTOR for this update. A model that is missing was not on those official pages we used, or it was a related RP or finish variant that we already consolidated onto a listed page. We did not invent specs from retailer listings.
Do you use prices, customer ratings or hands-on tests in the score?
No. The score uses only official published specification fields. We do not publish prices, star ratings or lab tests. Buy buttons say Check price and go to an Amazon search for the official model name.
What happens when an official table leaves a scored field blank?
We show Not listed and score that field at the lowest official value any other product in this category actually published, so an unpublished figure never outranks a published one. We do not fill the blank with an average or with a retailer listing.
Why do some rackmount names mention an RP model on the same page?
When an official specification table lists a redundant-power RP variant with the same scored memory, Ethernet, CPU and bay figures as the non-RP model, we keep one product page and name the official RP record there. If the official scored fields differ, the models stay on separate pages.
Why isn't official expandable memory a scored field here?
Official maximum memory is printed on every card when the maker publishes it. It is not scored in this category because several official tables, especially entry-level Synology records we used, do not list a maximum expandable figure. Installed official memory is published on every product in this set, so that is the memory field we score.
