#MICRON SSD HEALTH CHECK SERIES#
Gregory Wong, principal analyst at Forward Insights, pointed out that it is noteworthy for Micron to maintain the performance level of the 5100 Series while migrating the flash to 64-layer 3D NAND. Micron claimed the 5200 SSDs could deliver up to 95,000 IOPS for random reads and 33,000 IOPS for random writes. Shaine said the performance levels are similar between the 51 drives, and Micron made enhancements to improve the performance consistency with the newer model.

The capacity range for the 5100 Series is 240 GB to 7.68 TB, and the older Micron SSDs are available in ECO, PRO and MAX performance/endurance options. Micron's 5200 Series is available only in a 2.5-inch drive form factor, whereas the 5100 Series also includes smaller M.2 SSD models. Endurance options for the new 5200 Series range from 870 TB to 8.4 PB written with the 5200 ECO model and 2.27 PB to 5.95 PB written with the 5200 PRO. IT managers can use Micron's Flex Capacity feature to adjust the drive's endurance, performance and capacity to suit their needs. The 5200 PRO model offers capacity options of 960 GB and 1.92 TB, and the 5200 ECO model ranges from 480 GB to 7.68 TB. The new read-intensive Micron SSDs ship in two models: the 5200 PRO, rated at less than two drive writes per day, and the 5200 ECO, capable of less than one drive write per day. Shaine said the two Micron SSDs use the same controller and component hardware and 90% of the same firmware to ease the transition for OEM and cloud customers. Micron's 51 enterprise SATA SSDs have few differences beyond the NAND flash technology. Same architecture for 5100/5200 Micron SSDs But Shaine said the projected date for price parity has been pushed out several times and Micron is betting on both SATA and NVMe moving forward. Industry analysts predict NVMe-based PCIe SSDs could reach price parity with SATA SSDs later this year, spurring greater adoption of the lower-latency, higher-performing NVMe drives. He said he expects the order to eventually shift to NVMe PCIe, SATA and SAS. Steve Hanna, a senior product marketing manager at Micron, said SSD market data shows the SATA drive interface is the most popular followed by SAS and NVMe PCI Express (PCIe). And we really see that growth is driving our SATA volumes that we're projecting out for the next several years." But there's a tremendous amount of drive growth and, in general, bit growth in the industry.
"This year, next year and for the foreseeable future there's no doubt the industry is making a transition to NVMe-class drives. "We absolutely see a market for SATA SSDs in the enterprise," Shaine said.
The single-port 5200 SATA SSDs target enterprise servers running latency-sensitive, read-intensive virtualized workloads such as online transaction processing, virtual desktop infrastructure, media streaming and business intelligence and data-driven support systems. Higher density 64-layer 3D NAND will enable a reduction in the price per GB, according to Matt Shaine, the product manager for Micron's 51 SSDs. The new 2.5-inch Micron SSDs use the latest 64-layer 3D triple-level cell NAND flash, a shift from the 32-layer technology built into the vendor's year-old 5100 Series. Micron this week launched a 5200 Series of enterprise SATA SSDs.
