Mercury M.2 
250GB M.2 NVMe Solid-state Drive

The Perfect Boot Drive Boost for PC
Get more from your computer
The newest member of OWC's Mercury family of high performance SSDs is an incredible performance, capacity and reliability upgrade for M.2 NVMe equipped computers, especially as a boot drive. Perfect for gaming, the Mercury M.2 SSD delivers quicker boot times, quicker game launch times, and reduced save/load operations - so you can get gaming faster.
Cutting edge flash technology
Not all flash is created equal. The new Mercury M.2 SSD is manufactured with the latest 3D MLC NAND flash, delivering superb dependability and unmatched speed. Up to 80% faster, it's the perfect upgrade for your M.2 equipped system. Plus, with NVMe (Non-Volatile Memory Express) technology, the Mercury M.2 drives utilize four PCIe 3.0 lanes for much faster communication with the computer's processor, reducing latency.
Capacity to spare
Many systems include a small stock SSD that can fill up quickly. The Mercury M.2 SSD is available in multiple capacity options to deliver the storage space boost you need for your system. Upgrading with a Mercury M.2 SSD gives you the freedom to do more with your PC.
The trick to even better boot performance
The Mercury M.2 SSD features SLC Write Emulation technology. This means, the drive initially writes to the first layer of flash, delivering the performance advantage of single layer flash on this initial write. The result: high performance in operations like boot up, game saves and loading.
The quality you depend on
OWC SSDs are proudly designed in Austin, TX, and undergo a rigorous 7-stage testing procedure including 100% burn-in resulting in unwavering dependability. The Mercury M.2 SSDs are backed by an OWC limited warranty and free USA-based lifetime support.
