GM528 1TB NVMe internal SSD

The GM528 is a 1 TB NVMe drive built on PCIe 4.0 x4 and 3D NAND. It targets office users, students, gamers and video editors who need fast boot times and responsive multitasking. The drive uses HMB instead of a DRAM cache.

Fits M.2 2280 slots in desktops.

The M.2 2280 form factor slides into any compatible slot. It works with PCIe 3.0 and 4.0 hosts, so older platforms still function at reduced speed. No DRAM cache means lower power draw and simpler thermal management. The graphene-copper layer spreads heat without extra bulk.

Sustains up to 5000 MB/s read

Sequential speeds of 5000 MB/s read and 4000 MB/s write are available when the host provides PCIe 4.0 x4. Dynamic SLC caching helps maintain throughput during heavy writes. On PCIe 3.0 the drive still operates but cannot reach the peak figures. The cooling solution keeps temperatures steady during extended gaming or 8 K streaming sessions.

Questions about this item

Will the GM528 throttle during long 5000 MB/s reads?

The graphene-copper cooler is built to keep temperatures low so the drive can sustain near-peak read speeds through extended sessions.

How hot or loud does the drive get under all-day workloads?

The passive graphene-copper heatspreader adds no noise and is designed to dissipate heat without active cooling.

What motherboard slot do I need for this M.2 2280 NVMe SSD?

A PCIe 4.0 x4 M.2 slot delivers the rated 5000 MB/s; a PCIe 3.0 slot works but limits throughput.
