HP L18845-001 256GB M.2 2280 PCIe 3.0 x4 Internal

This HP L18845-001 is a 256GB internal solid state drive built for laptops and desktops with an M.2 2280 slot. It uses a Western Digital PC SN520 controller to deliver solid-state speed for everyday workloads. The drive installs directly into the motherboard without cables. It suits system builders and upgraders who need reliable capacity in a compact form factor.

PCIe 3.0 x4 interface limits

The drive connects through a PCI Express 3.0 x4 interface, so its maximum throughput is bounded by that generation's lane bandwidth. If the host platform only provides PCIe 2.0 or a x2 electrical link, the SSD will operate at the slower link speed. The M.2 2280 form factor fits the standard keyed slot, but the slot must support PCIe signalling rather than SATA only. NVMe is the protocol used over this PCIe link.

Capacity decides fit

The single specification that determines whether this is the right part is the 256GB capacity. That figure fixes the total addressable space for the operating system, applications and user data. Choose this drive only when 256GB matches the storage budget for the target build. The model identifier SDAPNUW-256G-1006 confirms the capacity and controller pairing.
