Introduction and Quick Specs
Recently released data reveals that two-thirds of SSDs utilized in today's datacenters require an endurance rating of 1 drive write per day (DWPD) or less. To address these read-centric workloads, Micron is introducing the M510DC. Micron's M510DC fills the need for a high performance read-centric datacenter storage solution.
Micron's M510DC SATA III Enterprise SSD is a cost effective solution aimed at accelerating the transition from legacy HDDs to high performance all flash-based datacenter storage. Compared to HDDs, SSDs reduce storage bottlenecks by decreasing workload latency and massively increasing data throughput. Micron is marketing the M510DC as the first of its kind SSD with true TCG Enterprise level encryption. Enterprise level encryption is critical for banking, government, and medical industries. We have all witnessed data breaches and the devastating impact they have on these industries.
Micron has a large and diverse portfolio of non-volatile solid-state storage solutions. Micron's SATA portfolio includes the Crucial/Micron BX100 and MX200 for aftermarket client upgrades, the M600 for OEM Client Solutions, and the M510DC and M500DC for Enterprise Cloud/Web 2.0 storage applications. Micron's PCIe portfolio is comprised of the P420m for mission critical storage and the P320h for IO acceleration. In comparison to competing solutions, Micron rates the M510DC as having very good endurance, very good 128K sequential read/write performance, very good 4K random write performance, and an excellent price point. With far more endurance than competing TLC solutions and a lower price point than competing MLC solutions, the M510DC is an attractive option for read-centric datacenter applications with a 1-2 DWPD storage requirement.
We are seeing a transition to solutions that are more economical as SSDs become more prevalent in the datacenter. The M510DC follows this trend with a low price point, while at the same time employing a rich enterprise feature set. Designed for read-centric workloads, the M510DC will find its way into the datacenter, serving roles such as boot drives, VDI applications, content delivery and cloud storage. Micron states the M510DC is in production now and selling directly to datacenter equipment manufacturers through Micron's distribution partners.
The M510DC is a spinoff of the highly successful M500DC, with the only physical difference being the flash node. The M500DC employs higher performance, higher endurance 20nm planar NAND, and the M510DC employs more economical 16nm planar NAND. The M510DC comes in a 2.5" standard form factor. Endurance ratings and performance vary by capacity. Capacities offered include 120, 240, 480, and 960GB models.
Micron M510DC 480GB Internals and Specifications
Micron M510DC 480GB Internals
The drive's enclosure is typical Micron. Formed from both sheet and cast aluminum alloy, the 2.5"x 7mm enclosure is grey in color with an industrial style textured finish.
With the drive disassembled, we see there is a plastic spacer that separates the two halves of the drive's enclosure. We also note a blue thermal pad located on the cast half of the enclosure. The thermal pad contacts the drive's controller and DRAM package.
The M500DC and M510DC both employ the same PCB. The only difference between the two is the flash node. This half of the green PCB houses the drive's 8-channel Marvell 88SS9187 controller, one of the drives two 512MB DRAM packages, one of the drives five flash packages and all thirteen of the drives tantalum capacitors. In contrast to the M500DC, the M510DC employs 128GB less over provisioning with a RAW total capacity of 640GB for the 480GB model.
This half of the PCB houses the second of the drive's two 512MB DDR3 DRAM packages and the remaining four of the drive's five flash packages.
