Samsung has begun mass producing the first PCI-Express (PCIe) solid state drive (SSD) for next-generation ultra-slim notebook PCs.
Samsung started providing the new SSD to major notebook PC makers earlier this quarter. Apple is among these makers, that will use the new PCIe DDC for the MacBook Air.
The XP941 lineup consists of 512, 256 and 128GB SSDs. It delivers a level of performance that surpasses the speed limit of a SATA 6Gb/s interface. The SSD enables a sequential read performance of 1,400MB/s (megabytes per second), which is the highest performance available with a PCIe 2.0 interface.
The XP941 comes in the new M.2 form factor (80mm x 22mm), weighing approximately six grams - about a ninth of the 54 grams of a SATA-based 2.5 inch SSD. Also, the XP941's volume is about a seventh of that of a 2.5 inch SSD, freeing up more space for the notebook?s battery and therein providing the opportunity for increased mobility.
Samsung intends to expand its production volumes of high-performance 10-nanometer class NAND flash memory. Furthermore, Samsung plans to introduce next-generation enterprise Non-Volatile Memory Express (NVMe) SSDs in a timely manner, in an attempt to also take the lead in that high-density SSD market. NVMe is also a PCIe-based interface.
