Designed to replace the DC1000M for mixed-use workloads in data centre environments, Kingston's DC1500M uses a Gen 3.0 x4 NVMe PCIe interface to deliver high throughput with low latency via a U.2 connection.

The DC1500M comes in four capacities to cover most data centre needs; 960GB, 1.92TB, 3.84TB (the drive we are reviewing here) and the flagship 7.68TB model. The drive uses a Silicon Motion SMI 2270 16-channel controller combined with BiCS4 96-Layer 3D TLC NAND.

Kingston quote performance figures for the DC1500M series as up to 3,100MB/s for Sequential reads for the 960GB, 3.84TB and 7,68TB drives with the 1.92TB drive the fastest in the range at 3,300MB/s. Sequential writes are listed as up to 2,700MB/s across the range with the exception of the 960GB drive which is rated at 1,700MB/s.

4K Steady State read performance is listed as up to 440,000 IOPS for the 960GB drive, 510,000 IOPS for the 1.92TB model and up to 480,000 IOPS and 420,000 IOPS for the 3.84TB and 7.68TB models respectively. As for random writes, the 960GB drive is the slowest at 150,000 IOPS, next comes the 7.68TB drive at up to 200,000 IOPS, the 3.84TB drive is rated at up to 210,000 IOPS and the fastest is the 1.92TB drive at up to 220,000 IOPS.

Power consumption for the 3.84TB drive is quoted as 6.80W idle, 6.40W for average reads (6.63W maximum reads) and 14.20W for average writes (16W maximum writes). As you should expect from a drive aimed at data centre usage, it comes with enterprise-class power loss protection in the shape of power capacitors.

The drive has an endurance rating of 1 DWPD (Drive Writes Per Day) over the length of the 5-year warranty Kingston backs the drive with.

Physical Specifications:
Usable Capacities: 3.84TB.
NAND Components: BiCS4 96-Layer 3D TLC NAND.
NAND Controller: Silicon Motion SMI 2270 16-channel.
Cache: DDR4.
Interface: NVMe PCIe Gen 3.0 x4 / U.2.
Form Factor: 2.5″ x 15mm
Dimensions: 100.09 x 69.84 x 14.75mm.
Drive Weight: 155g.

Firmware Version: S67F0103.

The DC1000M is the latest addition to Kingston's data centre SSD portfolio. Designed for dealing with mixed-use workloads, such as high-performance cloud servicing, web hosting, high-resolution media capture and transport and virtualisation, it features a U.2 connector and uses a 16-channel controller combined with 3D TLC NAND.

This SSD is available in four capacities at the time of writing; 960GB, 1.92TB (the drive we are reviewing here), 3.84TB and the huge 7.68TB flagship drive make up the DC1000M range. The DC1000M uses a Silicon Motion SM2270 16-channel controller which looks after Kioxia BiCS3 64-layer 3D TLC NAND.

Sequential read performance is the same for all four drives-up to 3,100MB/s while Sequential writes vary with capacity. The 960GB is rated up to 1,330MB/s, the 1.92TB 2,600MB/s, 3.84TB 2,700MB/s and up to 2,800MB/s for the 7.68TB drive.

Random 4K performance is quoted as up to 400,000 IOPS / 125,000 IOPS for read and writes respectively for the 960GB drive, up to 540,000 IOPS reads and 205,000 IOPS writes for the 1.92TB drive. The 3.84TB and 7.68TB drives share the same 210,000 IOPS write figure with the 3.84TB drive having a faster read speed at 525,000 IOPS over the 485,000 IOPS of the flagship drive.

As far as power consumption is concerned the 1.92TB drive is rated at 5.22W idle, 5.31W average read with a maximum of 5.70W. Average writes are rated at 13.1W with a 13.92W maximum.

Endurance wise, 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.
