AS3304T v2: specifications and dated store comparison →Diskless 4-bay soldered-2GB 2.5GbE NAS
AS3304T v2; 2GB DDR4; diskless; 4 SATA bays
The AS3304T v2 is a 4-bay soldered-2GB 2.5GbE box. Digital Reviews confirms the RAM cannot be upgraded and did not speed-test the unit. TweakTown's 2026-09-10 SSD RAID 5 record (296/200 MB/s) could not be reread this round (HTTP 403). 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]
The 2GB DDR4 memory is fixed; choose its file and backup features before planning application hosting.[1]
1 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.
Living with it
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]
1 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. This model has one Ethernet port.[1]
Reads approached the 2.5GbE link ceiling in the SSD array; writes were slower.[5]
Soldered 2GB DDR4 cannot be upgraded (Digital Reviews, vendor-sent unit, no speed test). A TweakTown SSD RAID 5 sequential record of 296/200 MB/s exists from an earlier read of the same original article; it is not a 2026-09-11 reread. Treat that number as pending verification, not a live confirmation.[5][6]
TweakTown used four Patriot P2201TB SATA SSDs in RAID5. CDM8.0.5 measured296.33/200.84 MB/s sequential read/write at Q8T1. These are SSD-array figures; they do not predict a four-HDD workload.[5]
Digital Reviews used drives from Synology,WD and Seagate after replacing a failed disk. The NAS recognized them, but the author had not tested throughput and used a Gigabit core switch. The vendor supplied the enclosure.[6]
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.

2GB DDR4 is soldered with no upgrade path. Author quotes Asustor Windows sequential 287/293 MB/s but explicitly had not speed-tested the unit yet.
Read the original reviewDigital Reviews: AS3304T v2 setup and RAM limit
Tested: Vendor-sent AS3304Tv2; final drives HAT3300-4T4TB,WD30EFRX3TB,and two ST2000VN0042TB after replacing a failed WD disk. Author used a Gigabit core switch and explicitly did not benchmark speed. Shipped ADM4.3.0.RSB1,updated4.3.3.RH61 then5.0.0.RIN1.
Applies to: Exact model for install/RAM observations only. Do not use the quoted sequential figures as this author's measurements.
