NVM Express^® (NVMe^® is a specification defining how host software communicates with non-volatile memory across a PCI Express® (PCIe®) bus. It is the industry standard for PCIe solid state drives (SSDs) in all form factors (U.2, M.2, AIC, EDSFF). NVM Express is the non-profit consortium of tech industry leaders defining, managing and marketing NVMe technology. In addition to the NVMe base specification, the organization hosts other specifications: NVMe over Fabrics (NVMe-oF™) for using NVMe commands over a networked fabric and NVMe Management Interface (NVMe-MI™) to manage NVMe/PCIe SSDs in servers and storage systems.

The Plextor M5M is a high-performance mSATA 6 Gb/s SSD specifically engineered to give ultrabook, tablet PC, and other JEDEC MO-300 form factor users the speed and low power consumption benefits of the newest generation SSD technology.
Featuring Plextor’s True Speed Technology, exclusive firmware, and server-grade controller chip, the M5S SSD is capable to deliver stable data transfer speeds over the long period. In actual every-day computing environment, it is able to achieve and sustain the like-new performance even after intense activity.

The NVMe specification was designed from the ground up for SSDs. It is a much more efficient interface, providing lower latency, and is more scalable for SSDs than legacy interfaces, like serial ATA (SATA). The first part of the specification is the host control interface. The NVMe architecture brings a new high performance queuing mechanism that supports 65,535 I/O queues each with 65,535 commands (referred to as queue depth, or number of outstanding commands). Queues are mapped to CPU cores delivering scalable performance. Sims original for mac. The NVMe interface significantly reduces the number of memory-mapped input/output commands and accommodates operating system device drivers running in interrupt or polling modes for higher performance and lower latency. The NVMe specification also contains host-to-device protocol for SSD commands used by an operating system for: read, write, flush, TRIM, firmware management, temperature, errors and others.

The Plextor M3S SSD comes in 128GB (510MB/s read, 210MB/s write) and 256GB (510MB/s read, 360MB/s write) flavours, both of which are available now. The flagship M3S 512GB model (525MB/s read.

I researching a new SSD for my computer boot drive.

I was considering the new Plextor M5 Pro Extreme, price isn't bad for the 128GB version. I currently have an older Intel SSD drive installed inside an IcyDock adapter. The Plextor drive comes with a bracket and appears to be thinner- 9.5mm vs 7mm. Would my IcyDock adapter work with the new, thinner drive? Would their bracket fit onto our Mac HD sleds?

I prefer to use the current sleds and not house the drive in an optical bay.
