The Kingston DCP1000 NVMe PCIe SSD comes in 800GB, 1.6TB, and 3.2TB though as it is an Enterprise class drive even the smallest size will cost you over $1000. Even with a price beyond the budget of almost all enthusiasts it is interesting to see the performance of this drive, especially as Kitguru's testing showed it to be faster than the Intel D P3608. Kitguru cracked the 1.6TB card open to see how it worked and within found four Kingston 400GB NVMe M.2 SSDs, connected by a PLX PEX8725 24-lane, 10-port PCIe 3.0 switch which then passes the data onto the cards PCIe 3.0 x8 connector. Each of those 400GB SSDs have their own PhisonPS5007-11 eight channel quad-core controller which leads to very impressive performance. They did have some quibbles about the performance consistency of the drive; however it is something they have seen on most drives of this class and not something specific to Kingston's drive.
"Move over Intel DC P3608, we have a new performance king! In today’s testing, it was able to sustain sequential read and write speeds of 7GB/s and 6GB/s, respectively! Not only that, but it is able to deliver over 1.1million IOPS with 4KB random read performance and over 180K for write."

And, if the edge connector
And, if the edge connector had been a full x16?
> read and write speeds of 7GB/s and 6GB/s
7 GB/s is an excellent READ speed
for an x8 edge connector.
Here’s the math:
1 x PCIe 3.0 lane = 8 GHz / 8.125 = 984.6 MB/sec
4 x PCIe 3.0 lanes x 984.6 = 3,938.4 MB/sec
8 x PCIe 3.0 lanes x 984.6 = 7,876.8 MB/sec MAX HEADROOM
Kingston’s specs are here:
800GB – 6,800 / 5,000MB/s
1.6TB – 6,800 / 6,000MB/s
3.2TB – 6,800 / 6,000MB/s
