TS-433-4G: specifications and dated store comparison →A four-bay ARM model that prioritizes affordable capacity and routine QTS services.
Exact US MPN TS-433-4G-US; official hardware table TS-433-4G; 4 GB on board (non-expandable) Note: Reserves some RAM for use as shared graphics memory.; 4x 3.5-inch SATA 6Gb/s, 3Gb/s.
Official TS-433-4G: Cortex-A55, 4 GB onboard, HDMI none, QTS 5.2.9 on the hardware table. Benchmark.rs is a 2024 original article with a 165–180 MB/s copy band and unknown configuration. Hagensieker is owner RAID5 experience. Need to Know IT states it used published specs and AU prices — not an independent benchmark; ignore its fixed container/rebuild table. ChooseCompute has not tested the unit. See the review evidence ↓
A four-bay ARM model that prioritizes affordable capacity and routine QTS services.[1]
Plan the array and client path around 2.5GbE: 1 (2.5G/1G/100M); 1GbE: 1.[1]
The exact factory configuration and platform limits do not make this the safest default for that need: you need hardware media transcoding.[1]
Follow any specification for its full conditions and sources.
Living with it
This page covers TS-433-4G-US, mapped to the official TS-433-4G hardware table. CPU: ARM 4-core Cortex-A55 2.0GHz processor. Factory memory: 4 GB on board (non-expandable) Note: Reserves some RAM for use as shared graphics memory..[1]
Storage: 4x 3.5-inch SATA 6Gb/s, 3Gb/s. Connectivity: 2.5GbE: 1 (2.5G/1G/100M); 1GbE: 1. Advertised port speed is not a guarantee for one file transfer; drive count, RAID, protocol, client and switch can each become the limit.[1]
No applicable exact-configuration original test was found. The buying judgment therefore rests on manufacturer specifications and remains unsuitable for measured-performance claims.[1]
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.
John HagensiekerSep 4, 2023
Purchased TS-433-4G-US with four 4TB WD Red in RAID5. Time Machine worked. Disk 4 hot-swap rebuild about 16 hours. No MB/s. RAM is soldered.
Read the original reviewQNAP NAS Review TS-433-4G-US
Tested: Purchased TS-433-4G-US (~$379 then); four 4TB WD Red in RAID 5; file storage and Apple Time Machine; Qsync. Author states this is not a technical bench.
Applies to: Exact US TS-433-4G-US owner experience. Not a benchmark. Official memory is 4 GB onboard non-expandable; the author’s RAM-upgrade buying reason is wrong.
