Samsung 950 PRO 256GB M.2 NVMe SSD

The Samsung 950 PRO MZ-V5P256BW is a 256GB internal solid state drive in the M.2 2280 form factor. It connects via a PCI-Express 3.0 x4 interface using the NVMe protocol. The drive uses Samsung V-NAND technology and a UBX controller with 512MB DRAM cache. It is built for consumer workloads requiring high throughput.

Suits professionals needing sustained NVMe speed

This drive suits professionals running intensive workloads that benefit from sequential reads up to 2200 MBps and writes up to 900 MBps. Random read performance reaches 270,000 IOPS at queue depth 32. Users with lighter workloads or older platforms lacking PCIe 3.0 x4 M.2 slots should consider other options.

PCIe 3.0 x4 NVMe interface decides compatibility

The single specification that decides fit is the PCI-Express 3.0 x4 NVMe interface. Your motherboard must provide an M.2 slot wired for PCIe 3.0 x4 and NVMe support to achieve the rated 2200 MBps read speed. Without this exact interface the drive will not operate at its designed performance level.

Questions about this item

Will the M.2 2280 PCIe 3.0 x4 drive fit in a motherboard with an M.2 slot that supports NVMe?

Yes, the 950 PRO uses the M.2 2280 form factor and a PCIe 3.0 x4 interface with NVMe, so it installs in any motherboard M.2 slot wired for PCIe NVMe operation.

How can I verify the 950 PRO is delivering the rated 2200 MBps sequential read and 900 MBps sequential write after installation?

Run a benchmark such as CrystalDiskMark at queue depth 32; the results should approach 2200 MBps read and 900 MBps write, while Samsung Magician will also report the drive health and firmware status.

Does the retail package include a heatsink or mounting screw, or must they be purchased separately?

The drive ships as the bare M.2 2280 module only; a motherboard standoff screw is typically supplied with the motherboard, and any heatsink is an optional separate purchase.
