An OEM-grade replacement drive for HP and other business systems.

The KIOXIA BG4 256GB (KBG40ZNV256G, HP spare L57447-001) is an M.2 2280 PCIe Gen3 x4 NVMe SSD built with 96-layer BiCS FLASH TLC. Used as factory storage in HP business systems, it is a low-power, reliable replacement for laptops and desktops that need a matching 256GB NVMe drive.

Restore Business Systems With a Matching OEM Drive

When a business laptop’s SSD fails, mismatched replacements can complicate imaging and support. IT teams and repair shops prefer drives that match the original specification.

This BG4 module is the same class of drive HP used as factory storage. It restores systems to their original configuration with dependable NVMe performance and low power draw.

Reliable NVMe Performance

PCIe Gen3 x4 NVMe delivers quick boots and responsive business apps compared with SATA SSDs and hard drives.

Efficient OEM Design

The DRAM-less controller with Host Memory Buffer keeps power low, helping laptops achieve their rated battery life.
