Samsung SM951 512GB PCIe SSD




The SM951 comes in a M.2 2280 form factor. That means 22mm wide and 80mm deep. Many Z97 and most X99 chipset motherboards have a dedicated slot for this size. In 2015, several notebooks will also ship with a 2280 form factor slot. Our Lenovo X1 Carbon supports up to 2280, even when you order the system with a SATA SSD. The system will ship with a 2280 M.2 SSD, but with a SATA-based controller.


The part number for the Lenovo model is MZHPV512HDGL-000L1. The L1 portion is for a specific customer, in this case Lenovo.




With the sticker removed we see the Samsung controller, DRAM package and two of the four NAND flash packages.




The other side of the drive holds two more NAND flash packages as well as some surface mount components. It should be noted that Samsung glued two of the surface mount components to the PCB near the M.2 edge connector. These sit on the opposite side of the controller, the main source of heat generated by modern SSDs. We'll measure the controller temperature later in this review.




The UBX controller is a 3-core ARM based unit that runs the AHCI command set. In our initial introduction to the SM951, Samsung stated this controller is capable of both NVMe and AHCI, but this product is currently running AHCI.




The NAND flash is Samsung's 10 nanometer class MLC flash.




The DRAM is also from Samsung.
