On the next page we'll talk a little more about NVMe. This enables NVMe devices to function within the existing operating system I/O stack protocol. To be able to make use of the new NVMe based devices inside your PC you have to have a proper driver installed, Windows 7, 8 and 10 have this NVMe protocol driver embedded. NVMe cuts corners by removing components within the I/O path like that good old fashioned RAID controller. The idea behind NVMe is to improve the storage stack by optimizing the way an application accesses a Flash device. NVMe is also known as Non-Volatile Memory Express or the Non-Volatile Memory Host Controller Interface Specification. With the M.2 form factor SSDs, more consumers with desktops or ultra-thin PCs can benefit from best-in-class performance and reliability of the technology. 64 layer (BICS) actually is going into production this year as well. Current V-NAND stacks have 32 and even 48 cell layers vertically over one another, rather than decreasing cell dimensions to fit onto a fixed horizontal space, resulting in higher density and better performance with a smaller footprint. Also, installed NAND toolsets in the wafer fabs can, for the most part, be reused, thereby extending the useful life of fab equipment. The good news is continued cost reduction, smaller die sizes and more capacity per NAND chip. In V-NAND, NAND layers, not chips, are stacked in a single IC. V-NAND is physical vertical NAND cell stacking not to be confused with chip stacking in a multi-chip package. Given its size, this has to be vertical stacked nand or V-nand. So the sample that have arrived in our test lab is the 512GB M2 version of the drive with that heatsink slash cover. The M8Pe series will come with MLC NAND flash memory from the 15nm Toshiba NAND node. Plextor is to offer four volume size versions of the products initially, the 128GB, 256GB, 512GB and 1 TB models. Combined with the PCIe Gen 3 x4 interface, the M8Pe can provide breakthrough performances with maximum continuous sequential read/write speeds of up to 2500/1400 MB per second, and random read/write speeds of up to 280,000/240,000 IOPS. One with just the bare M2 unit (M8PeGN), another one with the M2 unit + heatsink cover (M8PeG) and then the last series will be the M2 unit mounted into a PCI Express daughter card (M8PeY). With NVMe 1.2 support, the M8Pe significantly reduces access latency to provide faster data transmission speeds. The Microsoft NVMe driver is a balanced catchall that works for both desktops and notebooks, but it doesn't favor one over the other.Plextor will release these puppies all as MS unit, but separated into three lines. Many of the products in the test still use the in-box Microsoft driver that ships with modern versions of Windows. If any company were to kick off the trend, it would be Samsung, largely because the company has the resources to invest in the technology. Companies could release a desktop driver that focuses on high performance, and a notebook driver that focuses on increased efficiency. Over time, we may see NVMe drivers that target different environments. The 960 series is a departure from what we've come to expect from the Samsung SSDs that often dominate the power efficiency chart. The two are often related and work against each other because higher performance usually requires more power. The driver increases system performance, but it comes at the expense of battery life. We learned during the Samsung 960 Pro review that Samsung's new NVMe 2.0 driver reduces notebook battery life in our test with BAPCo's MobileMark 2014.5.
