4.25/5 (4)

WD issued Blue and Green branded SATA SSDs, which are based on SanDisk technology for the first time.

The Green brand is for secondary storage, being reliable, cool and eco-friendly, whereas Blue ones are built for PC primary storage use. Other WD brand colours include Black for enthusiast products and Red for NAS and SOHO (small office, home office) use.

The Blue and Green SATA SSDs are designed to be used mainly in notebooks, PCs and workstations. The Blue product is optimized for multi-tasking and resource-heavy applications. Still, WD states that the Green SSDs deliver essential-class performance, and are a great option for every-day use.

Is NVMe Really Revolutionary?
Posted by Jon Toigo on August 19, 2016
4/5 (1)

To hear advocates talk about NVMe – a de facto standard created by a group of vendors led by Intel to connect flash memory storage directly to a PCIe bus (that is, without using a SAS/SATA disk controller) – it is the most revolutionary thing that has ever happened in business computing.  While the technology provides a more efficient means to access flash memory, without passing I/O through the buffers, queues and locks associated with a SAS/SATA controller, it can be seen as the latest of a long line of bus extension technologies – and perhaps one that is currently in search of a problem to solve.

I am not against faster I/O processing, of course.  It would be great if the world finally acknowledged that storage has always been the red-headed stepchild of the Von Neumann machine.  Bus speeds and CPU processing speeds have always been capable of driving I/O faster than mechanical storage devices could handle.  That is why engineers used lots of memory – as caches ahead of disk storage or as buffers on disk electronics directly – to help mask or spoof the mismatch of speed.
