Enterprise Flash Storage Hits 8 Tbytes

Dec. 15, 2016
Micron Technology’s 5100 enterprise solid state drive (SSD) includes its FlexPro tunable architecture.
1. Micron’s 5100 enterprise family includes SSDs as well as M.2 modules.

TLC (triple level cell) flash storage is pushing its way into the enterprise with the promise of high capacity storage to replace magnetic disks. The challenge is delivering drive lifetimes that meet enterprise requirements while providing the superior performance of flash memory.

Micron Technology’s 5100 enterprise solid state drive (SSD) uses TLC flash to deliver from 240 Gbytes to 8 Tbytes of storage in platforms that include 2.5-in drives and M.2 modules (Fig. 1). The M.2 modules top out at 1,920 Gbytes. Sequential read speed is 549 Mbytes/s. The drives come in three flavors that address different applications:

  • Micron 5100 ECO – It targets cloud services and it is optimized for content sharing, such as video and media streaming. It delivers consistent data throughput and fast information delivery, and can handle 1 driver write/day (DWPD).
  • Micron 5100 PRO – This targets most applications by providing consistent performance for latency-sensitive applications. It supports 1 to 3 DWPD.
  • Micron 5100 MAX – This family is designed for demanding storage applications. It supports up to 5 DWPD.
2. Micron’s FlexPro software allows changes to the overprovisioning of the 5100 drives.

Part of the difference is the percentage of spare, over-capacity storage needed with flash memory. The ECO version has about 15%, while the MAX has 60%. Users can also take advantage of Micron’s FlexPro tuning support that allows this over-provisioning to be changed (Fig. 2). It can deliver up to 74,000 random write IOPS.

3. Overprovisioning affects performance and lifetime. FlexPro allows users to trade off one versus the other.


The three versions of the 5100 essentially have different default overprovisioning settings. These can be changed using the Storage Executive management software, although this is typically done when the drive is used. The tradeoff between long-term performance and capacity is one that users will need to consider, but they now have an option to make the adjustment (Fig. 3). The drives target the enterprise, but they are of interest for embedded applications, as well—especially when the drive performance and longevity can be tuned to the application.

Self-encrypting drive (SEC) support is optional, as is TCG Enterprise and FIPS 140-2 validation. The system uses Marvell’s 88SS1074 flash controller.
