Bestoss GM328 512GB NVMe SSD
The Bestoss GM328 is a 512GB internal solid-state drive built for consumer laptops and desktops. It uses the M.2 2280 form factor and connects through a PCI-Express 3.0 x4 interface with the NVMe protocol. The drive employs 3D NAND TLC flash memory to deliver sequential reads up to 3200 MBps and writes up to 2500 MBps.
HMB and Dynamic SLC Cache
This model operates without a dedicated DRAM buffer and instead uses Host Memory Buffer technology combined with a Dynamic SLC Cache. The combination is designed to maintain software and hardware synergy for smooth loading and system responsiveness. It supports plug-and-play installation on Windows and Linux systems across laptops, desktops and all-in-one PCs.
512GB capacity for everyday workloads
The 512GB capacity provides space for operating systems, applications, documents, photos, videos and games. TLC NAND flash offers longer write endurance than QLC alternatives, supporting reliable daily work, productivity tasks and gaming. The drive has undergone 88-hour endurance testing to verify stability and shock resistance for continuous operation.

Questions about this item
Will the GM328 512GB need a DRAM cache upgrade later?
The GM328 512GB has no DRAM cache and uses HMB instead; the controller manages mapping through host memory so no separate cache module can be added.
What limits the GM328 512GB during long sustained writes?
The dynamic SLC cache absorbs bursts, but once it fills the drive writes at native TLC speed, which is lower than the 2500 MBps peak.
How hot or loud does the GM328 512GB get when running all day?
The M.2 2280 NVMe drive has no moving parts and draws power only from the PCIe 3.0 x4 slot, so it stays silent and typically runs within normal SSD thermal limits.
