This case-less SSD features sequential read speeds of up to 540 MB/s and sequential write speeds of up to 500 MB/s allowing for the rapid transfer of large files. By utilizing SATA III technologies, this drive is able to deliver data performance to your system as well as ensuring compatibility as a boot drive. This Samsung SSD even comes with 512MB of low power DDR3 SDRAM used as cache memory to enhance processing speeds.With a M.2 form factor, this solid state drive is designed to be used in a variety of notebook, ultrabook, and desktop computers. The SSD's reduced size is achieved through the use of Samsung's 3D V-NAND flash memory as each of the 32 cell layers are stacked vertically rather than horizontally. Samsung also implements their own TurboWrite technology to deliver enhanced sequential read and write speeds while Rapid Mode software utilizes the integrated cache (DRAM) memory to improve processing speeds. Insert this drive into a notebook with an M.2 slot, and it will benefit from improved battery life with the MGX controller allowing the drive to sleep at an efficient 2 mW.
