Bestoss GM528 2 TB NVMe SSD

The Bestoss GM528 is a 2 TB internal solid-state drive built for desktops and laptops. It uses an M.2 2280 form factor and connects through a PCIe 4.0 x4 interface with the NVMe protocol. The drive targets everyday computing, creative workloads and mainstream gaming.

PCIe 4.0 x4 interface with NVMe

The single specification that decides fit is the PCIe 4.0 x4 interface paired with NVMe. Your motherboard or laptop must provide an M.2 slot wired for PCIe 4.0 to reach the advertised throughput; a PCIe 3.0 slot will work but caps the transfer rate.

2 TB capacity with 5000 MBps read

The 2 TB capacity holds operating systems, applications and large media libraries with room to spare. Sequential reads reach up to 5000 MBps and writes up to 4000 MBps, so game loads and video scrubbing stay fast. Sustained heavy writes will eventually hit the dynamic SLC cache limit and slow to the native TLC NAND speed.

Questions about this item

Will this drive fit in a standard M.2 2280 slot on my laptop or desktop?

Yes, the GM528 uses the M.2 2280 form factor, which matches the most common slot length for both laptops and desktops.

Does it need a separate heatsink or does the built-in cooling handle heavy workloads?

It includes a graphene-copper cooling solution designed to sustain near-peak read speeds during extended gaming or creative sessions without an extra heatsink.

What speeds should I expect if my motherboard only supports PCIe 3.0?

The drive is backward compatible with PCIe 3.0, but maximum sequential read and write speeds of 5000 and 4000 MB/s require a PCIe 4.0 x4 connection.
