The Samsung 950 Pro is the new flagship consumer solid state drive and it flips the backwards compatibility plan and the 2.5" SATA form factor of the three previous iterations of the 8xx Pro family in favor of a PCI Express 3.0 x4 connection in the M.2 2280 form factor coupled with the NVMe protocol. Those changes allow for one of the biggest generational performance jumps in the history of the SSD industry and should help the transition of SSDs shedding the last Specifications and limited feature sets of their mechanical hard drive predecessors.
The M.2 2280 form factor has the potential to unify the consumer Solid State Drive market, with a physical size small enough for ultrabooks but a large enough capacity for all users. M.2, depending on the exact implementation used by the OEM, has the ability to provide SATA or high-performance PCIe connectivity, easing the transition. By supporting up to four lanes of PCIe 3.0, M.2 has helped make the two-lane SATA Express standard dead on arrival and ensures that drives won't be starving for bandwidth again for quite some time. In the Desktop form the only downside is its compatibility is really limited to the Z97, Z170, H170 and X99A Chipset from Intel at present. With this put aside the storage gains easily out weighs the compatability with speeds up to 2.5Gb/s on Read and up to 1.5Gb/s on write tasks delivery optimum storage speeds unheard of before.
All of these new PCIe solid state drives come in 512B and 256MB capacities on the PCIe M.2 PCIe solid state drive interface to allow capability with most desktop systems available today. running on the Z170 and X99 chipsets As usual with Samsung solid state hard drives are all featuring tool less installation allowing you to have your system up in a flash with fast PCIe SSD Storage.
