Micron 9100 MAX 2.4TB Enterprise PCIe NVMe SSD Review

TweakTown Rating: 98%Manufacturer: Micron





The drive ships in a clear plastic clamshell container. Micron includes both a half-height and full mounting bracket.





The top half of the drive's all black PCB is covered by a full-length aluminum heat sink. A grey shroud covers half of the heat sink to help direct and optimize airflow.




The bottom half of the PCB has no shielding; the components are exposed. This half of the PCB houses 16 of the drive's 32 Micron 16nm flash packages and five of the drive's nine Micron DRAM cache packages. Eight DRAM packages are dedicated for block placement and wear leveling data. The ninth DRAM package is dedicated for ECC further guaranteeing data integrity.




From this angle, we can see the opening at the back of shroud covered portion of the heat sink where a minimum of 300LF per minute of airflow is to be funneled, exiting through the drive's perforated mounting bracket. Two electrolytic capacitors provide enough power to flush data in transit to the NAND array in the event of a host power loss.




Removing the heat sink reveals that the drive's controller and major components are fitted with thermal pads to wick heat away. This side of the PCB houses the drive's controller, 16 of its 32 NAND flash packages, four 512MB DRAM cache packages, and dual electrolytic capacitors.




A detailed view of the drive's 16-channel, 16-core Microsemi (formerly PMC) 500MHz ASIC controller.




A detailed view of one of the drive's 128GB (32 in total) Micron 16nm BGA flash packages. Thirty two 128GB flash packages gives the 9100 MAX 2.4TB a raw total of 4096GB of flash. 2.4TB is available the end-user before formatting.




A detailed view of some of the drive's (9 in total) 512MB Micron 1600MHz DDR3 DRAM cache packages. Eight 512MB DRAM packages (4GB) serve as onboard data cache; the ninth 512MB cache package is dedicated for ECC.
