256GB PCIe Gen3 x2 NVMe 1.3 SSD
The Western Digital PC SN520 SDAPMUW-256G is a 256GB internal solid-state drive built on 64-layer 3D NAND. It uses an M.2 2242 form factor and a PCIe Gen3 x2 interface with NVMe 1.3 protocol. Sequential speeds reach up to 1700 MBps read and 1300 MBps write.
Suits thin laptops and compact PCs with a 2242 slot
This drive fits systems that accept the shorter 2242 length. It is not compatible with bays that only support longer modules. Low idle power of 25 mW and sleep power of 2.5 mW help battery life in mobile devices.
PCIe Gen3 x2 lane configuration
The x2 link caps sequential throughput below what a four-lane drive can deliver. Check that your platform can boot from NVMe and that the M.2 key matches before purchasing.

Pytania dotyczące tego produktu
Will my motherboard need an M.2 2242 slot with PCIe Gen3 x2 NVMe 1.3 support for this drive to work?
Yes, the drive requires an M.2 2242 key-M slot that provides a PCIe Gen3 x2 NVMe 1.3 interface; without that exact slot the SSD cannot be installed or detected.
Can I keep my older PCIe Gen3 x4 NVMe drive installed alongside this PCIe Gen3 x2 model?
Yes, both drives use the same NVMe protocol on PCIe Gen3; the x2 drive simply negotiates two lanes while the x4 drive uses four, so they coexist without conflict on separate M.2 slots.
How can I confirm the 1700 MBps sequential read and 1300 MBps sequential write speeds after installation?
Run a standard NVMe benchmark tool such as CrystalDiskMark using a 1 GiB test file on an empty partition; the reported sequential read and write results should approach the stated up to 1700 MBps and up to 1300 MBps figures.
