AS5404T: specifications and dated store comparison →Diskless 4-bay N5105 NAS, 4GB/16GB, four M.2, dual 2.5GbE
AS5404T; 4GB (1 x 4GB); diskless; 4 SATA bays
The AS5404T is the 4-bay N5105 Nimbustor: 4GB/16GB, four M.2, dual 2.5GbE. IT Pro / Simon Handby (PC Pro) measured ATTO 2MB 281/256 MB/s and a 283 MB/s large-file read on 4×1TB HDD RAID 5 plus NVMe RAID 1, single 2.5GbE. TechRadar is the same original test, not a second lab. See the review evidence ↓
4 SATA bays set the main capacity and redundancy choices. RAID 5/6 can trade usable capacity for one/two-drive failure tolerance when enough drives are installed. Use the model compatibility list before buying drives.[1]
Fast network ports and SSD slots add value only when the client, switch and workload can use them.[1]
2 x 2.5 Gigabit Ethernet (2.5G/1G/100M); confirm the rest of the network and drive layout.[1]
Follow any specification for its full conditions and sources.

2 x 2.5 Gigabit Ethernet (2.5G/1G/100M). A port rate is a link rating; protocol overhead, client storage and the array reduce file-transfer rates. Combining ports requires suitable network/client configuration.[1]
Large files were much faster than the small-file workload. SSDs gave little benefit for this single-user file-copy case.[5]

ITPro reported smooth HD playback while Handbrake transcoding in Docker used almost all CPU capacity and a large file copied. No codecs or transcode speed were disclosed, so this supports a qualitative multitasking observation rather than a guaranteed number of streams.[5]
The review found little copy-speed change on a separate SSD volume, a two-HDD 12TB mirror or with SSD cache. It also notes that one SSD cache cannot accelerate multiple disk volumes. Benefits for repeated database or multi-user access were not measured.[5]
Our buying advice combines official specifications with the original reviews below. We have not tested this product ourselves. Expand a review for its setup, measurements and limitations.

Tested: Four 1TB HDDs in RAID 5 and two 1TB NVMe SSDs in separate RAID 1, synchronized before testing; storage loaned by Western Digital, exact drive models not disclosed. Single 2.5GbE link; Windows 11 laptop for copies. Also tested a two-HDD 12TB RAID 1 array and SSD caching.
Applies to: Exact enclosure model; conclusions apply to the stated tested storage and network setup.

No. This page covers the factory-memory diskless enclosure with 4 SATA bays. Check the exact configuration in each seller listing.[3]
16GB (2 x 8GB) Support mixed capacity. Follow the supported module configuration; third-party RAM compatibility is not guaranteed by a matching capacity alone.[1]
Large files were much faster than the small-file workload. SSDs gave little benefit for this single-user file-copy case.[5]
No. Btrfs snapshots help recover earlier file states on the NAS; keep another copy on separate storage and test restoration.[1]
