Kingston’s DC1000M drive has been designed for mixed-use workloads in the data centre and enterprise environments. As such, the drive implements Kingston’s QoS (Quality of Service) requirements to ensure predictable random I/O performance and low latencies over a wide range of read and write workloads. The DC1000M range consists of four drives (at the time of writing) from the entry-level 960GB drive through 1.92TB and 3.84TB models to the huge 7.68TB flagship drive.

At the heart of the DC1000M lies a Silicon Motion SM2270 16-channel controller which is combined with Kioxia BiCS3 64-layer 3D TLC NAND. The drive uses a U.2 (PCIe NVMe Gen3 x4 ) interface which is hot-pluggable and compatible with U.2 backplanes of storage systems and enterprise servers.

Kingston quotes Sequential read/write figures for the 1.92TB DC1000M as up to 3,100MB/s and 2,600MB/s respectively. Incidentally, that read figure is the same across the range (write performance for the rest of the range is quoted as 1,330MB/s for the 960GB, 2,700MB/s for the 3.84TB drive and 2,800MB/s for the flagship 7.68TB drive).

We confirmed both official figures with the ATTO benchmark, the review drive producing a read figure of 3,380MB/s and 2,690MB/s for writes. Using our own Sequential tests we saw a peak read score of 3,543.38MB/s (QD256) with writes peaked at 2,966.91MB/s (QD256).

Random 4K performance for the 1.92TB drive is quoted as up to 540,000 IOPS for reads and up to 205,000 IOPS for writes. Using our standard 4-threaded tests, we saw a peak read figure of 521,583 IOPS at a queue depth of 32, not that far away from that maximum figure. When it came to write performance the best we saw from the drive was 435,015 IOPS (QD128) far, far exceeding the official 205,000 IOPS. However switching over to using 8K data, the drive peaked at 240,903 IOPS (QD256) much, much closer to the official figure.

As you might expect the DC1000M comes with a wealth of enterprise-class features including; power loss protection (PLP), telemetry monitoring for increased data centre reliability and end-to-end data path protection. As for the drive's endurance, Kingston rate the 1.92TB drive at 3362TBW which works out at 1 Drive Write Per Day (DWPD) over the 5-year length of the drive's warranty.

Pros

• Overall Performance.
• Endurance.

Cons

• Inconsistent performance in our 4K 70/30 read/write tests at deeper queue depths.
• Pricey.

KitGuru says: Kingston’s DC1000M range offers useful capacity sizes, ending up at a huge 7.68TB model. The drive has the hardware power protection, end to end data protection and enterprise-grade performance stability IT managers demand from an SSD of this class.
