Bestoss GM228 2TB NVMe SSD

The Bestoss GM228 is a 2TB internal solid-state drive built on the M.2 2280 form factor with a PCIe 3.0 x4 interface and NVMe protocol. It uses 3D NAND flash and operates without a dedicated DRAM cache, relying on HMB and dynamic SLC caching for performance. Sequential reads reach up to 2200 MBps and writes up to 1500 MBps.

Suits everyday PC and laptop upgrades

This drive fits users who want a straightforward capacity boost for a desktop, laptop or NAS that has an M.2 slot wired for PCIe 3.0 or 4.0. The package includes a screwdriver and mounting screws for a simple installation. Buyers needing sustained heavy write workloads or the highest random IOPS should consider drives with dedicated DRAM and higher endurance ratings.

PCIe 3.0 x4 interface decides fit

The drive connects through a PCIe 3.0 x4 link, so the host slot must support that interface to deliver the rated 2200 MBps read speed. A PCIe 4.0 slot will run the drive at 3.0 speeds, while a slot wired only for two lanes or an older protocol will limit throughput further. Check the motherboard or laptop specification for M.2 PCIe 3.0 x4 support before purchasing.

Questions about this item

My motherboard only has a PCIe 3.0 M.2 slot — will the GM228 still reach its rated 2200 MB/s read speed?

Yes. The GM228 uses a PCIe 3.0 x4 interface and its maximum sequential read of 2200 MB/s is specified on that generation, so a PCIe 3.0 slot provides the full bandwidth the drive needs.

I have an older desktop with a PCIe 3.0 M.2 slot — will the GM228 work without a firmware update?

The drive follows the standard NVMe protocol over PCIe 3.0 x4 and is described as plug-and-play compatible with desktops, so it should be recognised by the system BIOS without a separate firmware step.

After installing the GM228, how can I verify it is delivering the advertised 2200 MB/s read performance?

Run a benchmark such as CrystalDiskMark on the freshly formatted drive; a sequential read result close to 2200 MB/s confirms the SSD is operating at its specified PCIe 3.0 x4 speed.
