Kingston DCP1000 Enterprise NVMe SSD Review (1.6TB) – 7GB/s & 1 Mil IOPS in a Single HHHL SSD

8KB RANDOM READ/WRITE

To measure 8KB random read/write performance do the same preconditioning as we did for 4KB performance. The drive is first secure erased to get it in a clean state. Next, the drive is filled by sequentially writing to the RAW NAND capacity twice. We then precondition the drive with 8KB random writes at QD256 until the drive is in a steady state. Finally, we cycle through QD1-256 for 5 minutes each for writes and then reads. All this is scripted to run with no breaks in between. The last hour of preconditioning, the average IOPS, and average latency for each QD is graphed below.

Kingston DCP1000 - 8KP

The 8K write preconditioning results follow similar to that of the 4K results. Here we can see a performance distribution of about 40K IOPS and latency up to 7ms.

Kingston DCP1000 - 8KRIOPS

Just as before, the Kingston DCP1000 just absolutely dominates in read performance. It has the lowest latency and the delivers the highest IOPS out of any of the other drives we have tested. At QD256 it averages a staggering 664K IOPS, over 160K IOPs more than any drive we have tested.

Kingston DCP1000 - 8KRLAT

Latency keeps below 0.20ms up until QD 64. At QD 128 it averages 0.204ms and at QD256 it averages 0.385ms.

Kingston DCP1000 - 8KWI

Again, while the consistency profile on write performance doesn’t look to be so good compared to the rest of the SSDs we have tested, the average write results prove to be very very good.

Kingston DCP1000 - 8KWL

Except for the Micron 9100 MAX, the Kingston DCP1000 delivers the highest performance in 8K writes out of all the SSDs in the comparison and seems to max out at around 100K IOPS.

    wow this one is a true beast

    What raid level did you use for the four logical drives ?

    • RAID 0. Stay tuned as we are doing same to two of these drives soon.
