Lexar NM610 Overview
The Lexar NM610 is your typical M.2 2280 drive so it is 80mm long. This is the standard M.2 size so you should have no problem getting this drive to fit in an empty M.2 slot on your motherboard.
There is no heatsink or even a small heatspeader on the drive, which likely means the drive will not overheat. There is a sticker on the top of the drive that lets us know we do have the 500GB version of the NM610 as well as the serial number of the drive.
Flipping the drive over to the back we can see that there are no chips. Being 1-sided makes the drive more compatible with thin and light systems, especially laptops.
Removing the sticker on the main side of the drive we can get a better look at the controller, which is the Silicon Motion SM2263XT. This is a 4-channel PCI-Express 3.0 x 4 NVMe controller that features Host Memory Buffer (HMB). That is why there is not a DRAM cache chip on the drive. Instead using HMB it uses the system’s RAM as cache.
There are four NAND chips on the drive. These are marked as “N2TTE1B1FEB1”, which appears to be Intel 64-layer 3D TLC NAND flash chips.
