Is there 950 Evo coming?

[cst1992]

Benchmarks of Samsung's new 950 Pro M.2 drive indicate that the drive tops out at 2000/1500MB/s read/write speeds, and has room for expansion with PCI-E 3.0x4, which has a theoretical capacity of 3940 MB/s.

Does anyone know if a 950 Evo drive is coming? It should be able to replace the 850 Evo M.2 if it is.

No, I haven't heard anything about an Evo 950.

The 512GB Samsung 950 Pro reaches around 2500 MB/s sequential reads at QD2 (and up), not just 2000 MB/s. This is already fast enough to require PCIe 3.0 x4 to not be bottlenecked - either PCIe 2.0 x4 or PCIe 3.0 x2 would limit it to a theoretical maximum of ~2000 MB/s, and realistically around 1800-1900.

There's currently little competition for the 950 Pro, so I wouldn't expect a 950 Evo right around the corner. Once more players come up with high-performance NVMe SSDs, I'm sure Samsung will strike back, and the NVMe price wars will begin.

But isn't 3.0x4 double that - at 4000 MB/s? So how is it bottlenecked?

The only options are 2000 MB/s with PCIe 2.0 x4 / PCIe 3.0 x2 or 4000 MB/s with PCIe 3.0 x4. An SSD capable of 2500 MB/s will be bottlenecked on the interface that's only capable of 2000 MB/s, it needs PCIe 3.0 x4 to achieve its full performance.
