Micron Launches 3D NAND Client SSDsby Billy Tallis on May 31, 2016 11:00 AM EST
Today Micron is announcing their first client/OEM SSDs with 3D NAND. First mentioned at an enterprise announcement event in April, the Micron 1100 and 2100 SSDs are part of an aggressive transition strategy that has switched almost all of their flash production capacity over to 3D NAND and left only enough 16nm output to fulfill their obligations for existing product lines.
The Micron 1100 is a mainstream client SATA drive in M.2 and 2.5" form factors. It uses Marvell's 88SS1074 controller and Micron's 384Gb 32-layer TLC NAND and is the replacement for the Micron M600, which used their 16nm MLC. Micron's 3D TLC is unusual in having a capacity (48GB) that is not a power of two, but the 1100 retains the traditional drive capacity points of 256GB, 512GB and 1TB, and extends the line to 2TB. Micron hasn't yet disclosed how many dies and how much overprovisioning each model will have, but the 256GB model will probably include 6 dies giving a raw capacity of 288 GiB.
|Micron 1100 Specifications|

|Form Factors||2.5" 7mm, M.2 2280 single-sided||2.5" 7mm|
|4KB Random Read||55K IOPS||92K IOPS||92K IOPS||92K IOPS|
|4KB Random Write||83K IOPS||83K IOPS||83K IOPS||83K IOPS|
|DevSlp Idle Power||2mW||2mW||4mW||25mW|
The Micron 1100 has slightly reduced performance and endurance specifications relative to the M600, but it retains the full feature set including TCG Opal encryption, partial power loss protection and SLC caching. The Marvell 88SS1074 was designed with TLC NAND in mind and thus also brings LDPC error correction support.
The Micron 2100 M.2 PCIe NVME will be Micron's first client PCIe SSD and their first PCIe SSD with 3D NAND. Micron has not yet finalized the technical specifications for the 2100, but we do know it will be available in capacities up to 1TB as a double-sided M.2 2280 card.
The Micron 1100 will begin mass production in July, followed by the 2100 by the end of summer.
