Samsung SM951 128GB AHCI M.2 PCIe 3.0 x4 80mm (2280) Internal SSD - OEM
Key Specifications

  • Form Factor: M.2 2280 Internal SSD
  • Capacity: 128GB
  • Read Speed: 2000 MB/sec
  • Write Speed: 600 MB/sec
  • Warranty: 2 Yrs
  • Condition: New

"At this time, Samsung's SM951 is the fastest M.2 product you can buy. Not only is it quicker than existing PCIe-based M.2 drives, but it also delivers performance that compares to all-in-one RAID products like OCZ's RevoDrive and G.Skill's Phoenix Blade."

"Despite the lack of NVMe, there's no arguing about the fact that the SM951 is the fastest client SSD and by a very healthy margin."


Please Note We don't recommend secure erasing the SM951, and doing so may void your warranty. Although some have reported being able to successfully secure erase, there has been at least one case reported to us of the drive being rendered useless after several secure erases with Parted Magic.


The Samsung SM951 128GB AHCI M.2 PCIe 3.0 x4 80mm (2280) Internal SSD - OEM is the current world champion of M.2 SSD's, offering incredible performance in a tiny form factor. It provides up to a blistering 2150MB/s read and 1500MB/s write sequential data transfer rates (512GB capacity).

The Samsung SM951 128GB AHCI M.2 PCIe 3.0 x4 80mm (2280) Internal SSD - OEM is generally compatible in a wide variety of systems with a free M.2 socket, and can also be installed in systems without an M.2 socket using an M.2 to PCIe adapter. Full operating system boot support is available in both situations, so long as the correct support is built into the system UEFI BIOS code. Since the SM951 does not have it's own option ROM, this is an essential requirement. Below is a general guide but for more specific compatibility information see our monster M.2 compatibility guide, or contact us if you want to check compatibility in your system.

  • Most Z97-based motherboards. Note, some boards have just 2x PCIe lanes on the M.2 socket. Check your system documentation as 4x PCIe lanes are required for maximum performance). In addition, there are a limited number of PCIe lanes available on Z97 systems (maximum 16), so you should consider this when installing a PCIe m.2 SSD, as it will consume some PCIe lanes and limit the number available to your GPU(s).
  • All X99-based motherboards. Check your system documentation for any required M.2 socket switch changes, as 4x PCIe lanes are required for maximum performance
  • All Z170-based motherboards, with some boards even supporting 3 M.2 sockets that can be configured to have multiple M.2 SSD's in RAID. Note, like Z97 systems, there are a limited number of PCIe lanes available on Z170 motherboards. Some references say maximum 16 lanes, other say 20. Some of these lanes are used when M.2 PCIe lanes are installed in the system, which limits the number of PCIe lanes available for a discrete GPU.
  • All 2006-2010 classic model Mac Pro computers (when combined with a standard PCIe adapter)
  • New generation i7 model Intel NUC®
  • Many new generation laptops
  • **NOTE** - the SM951 is not compatible in any Apple MacBook, MacBook Pro, iMac, Mac Mini, or the current 'cylindrical' model Mac Pro.
  • Please refer to our monster M.2 compatibility guide for the latest information!

Key Features

  • Extreme performance - up to 2150/1500 sequential read/write data transfer rates
  • PCIe 3.0 device, backwards compatible with PCIe 2.0
  • Small M.2 form factor plugs straight into your PCIe-based M.2 socket with no additional cables required

What's in the Box

  • Bare SSD, enclosed in an anti-static bag, custom foam padding and custom box especially made for RamCity to package the XP941/SM951


  • 3 year warranty.
  • The Samsung SM951 is an OEM product and the 3-year warranty is not provided to the consumer, rather to us as the systems integrator. For any warranty or support enquiries, please contact RamCity directly.
