Kingston DC450R Overview

Kingston released a new data center SSD. The Kingston DC450R is a 2.5″ SATA SSD with capacities ranging from 480GB to 3.84TB. Launching a new 3D TLC SATA SSD in 2019 seems a bit strange to me at least. This is the year when there is an enormous transition to NVMe and competitors are moving to QLC NAND, especially for these applications. There was one other feature that caught our eye. e5-4610 v3

Kingston DC450R SATA SSD

The Kingston DC450R SATA SSD is a read optimized drive. That means it is designed for providing low power, vibration resistant performance between that of a hard drive and an NVMe SSD. When we read through the specs (below) this line caught our attention:

  • Power Loss Protection (Power Caps): No

This is extreme read optimization. Power Loss Protection (PLP) is designed to ensure data that is written to drives remains safe. A great example of this is from our What is the ZFS ZIL SLOG and what makes a good one piece.

ZFS ZIL SLOG Writing To Common Options

With an enterprise or data center SSD we expect that data is written to the drive and PLP ensures that during an unsafe power event, the data stays safe. With Kingston billing the DC450R as a data center SSD designed for edge deployments, power events can be more likely.

A 2.5″ SATA SSD with encryption and without PLP is essentially a consumer drive rather than a data center drive. That is not a bad thing. For write once read many style applications like CDNs this is perfectly fine. We would simply caution our readers to not think of this as a database SSD.
