Worth Buying: TERRAMASTER D4-320 4-Bay Enclosure — Put Your Loose Drives Back to Work, 10Gbps USB 3.2! $249.99 CAD

Amazon.ca has the TERRAMASTER D4-320 4-bay enclosure (diskless) for $249.99 CAD. Prime members ship free; otherwise free shipping on orders over $35.

This is a DAS, not a NAS — plug in one USB cable and it behaves as external drives for your computer. No network setup, no OS to install, no accounts to manage. The four bays stay independent with no RAID: four separate drive letters, and no reformatting when you move between machines or operating systems.

Speed is the selling point. USB 3.2 Gen2 gives a 10Gbps link; TerraMaster rates combined read/write at up to 1,016 MB/s with four 8TB SATA drives, and 510 MB/s read from a single SATA SSD. Each bay takes up to 22TB for 88TB total, and it accepts 3.5" hard drives, 2.5" hard drives and 2.5" SSDs. The USB-C port also works over Thunderbolt 3/4.

The trays are tool-free — slide a drive in, press and the push-lock holds it so it can't drop out. Drives are hot-swappable, so swaps don't need a shutdown. Cooling is a temperature-controlled fan with sound-absorbing panels and vibration damping; standby noise is under 21 dB(A), about half the previous generation, which matters if the unit sits on your desk.

One reviewer pulled the SATA drives out of an old HP home server, dropped them in and they were recognised without initialising — exactly the use case for anyone with a drawer full of loose drives. There's also a one-star report of IO errors and drives dropping off after 18 months. At this price point, keep backups and don't trust any single enclosure.

Two-year warranty. At $249.99 without drives it undercuts a comparable NAS by a wide margin, and it suits people who already own drives and don't want to run network storage.
