Kingston's DC450R is part of the company's extensive Enterprise SSD range and has been designed for handling read-centric workloads in data centres. We review the 3.84TB model, priced around the £440 mark for UK buyers.
The DC450R is available in five capacities at the time of writing: 480GB, 960GB, 1.92TB, 3.84TB (the drive we are looking at here) and the massive 7.68TB flagship drive. At the heart of the drive is a Phison PS3112-S12DC controller which looks after 3D TLC NAND.
Sequential read performance is quoted as up to 560MB/s across the range. Sequential write performance varies with capacity. The entry-level 480GB is up to 510MB/s, the 960GB and 1.92TB models are up to 530MB/s, the 3.84TB drive up to 525MB/s with the 7.68TB model the slowest in the line-up at up to 504MB/s.
When it comes to 4K random read performance all the range bar one are rated as up to 99,000 IOPS, the exception being the 960GB model which is rated at up to 98,000 IOPS. Random writes are a bit of a mix. The 1.92TB drive has the fastest random write rating at up to 28,000 IOPS, while the slowest is the 480GB model at 17,000 IOPS. The 960GB and 3.84TB drives are both rated as up to 26,000 IOPS with the 7.68TB flagship rated at up to 19,000 IOPS.
Power consumption for the 3.84TB is stated as 1.48W for Max/Avr reads, 3.93W for average writes and 5.5W for maximum writes with an idle figure of 1.3W.
Endurance for the 3.84TB drive is quoted as 2,823TB which works out at 0.4 DWPD over the length of the 5-year warranty Kingston back the drive with.
