NVME or Non-volatile Memory Express has been one of the breakthroughs that enterprise, business server solutions and extreme enthusiasts have been looking forward to in storage devices. While a direct impact of NVME is in reduction of latency in all areas, one side effect has been the promotion of PCI-E based SSDs. Tweaktown [1] has a wonderful article about this that we encourage everyone to read.
On the note of PCI-E SSDs, it is but one of several means towards breaking the SATA bottleneck. Anandtech [2] describes the possibly intermediate steps of Sata-Express and the aptly named SFF-8639 connectors, the latter being employed by Samsung for its XS1715 NVME 2.5″ SSD coming in with 400 GB, 800 GB and 1.6 TB of storage options [3]. The source link, again courtesy Tweaktown, has tests and further analysis done on the drive which again is a great read. A closer look inside courtesy the same source shows the connector:
One thing that strikes us immediately was the 4k random r/w tests where the XS1715 averaged in at over a whopping 750,000 IOPS (input/output operations per second) beating out even the Intel DC P3700 NVME SSD at just over 465,000 IOPS. While this by itself isn’t fully indicative of performance to the enthusiast, several other factors listed in the source make this something to keep an eye out for- even if the price hasn’t been announced yet. As a reference, the high end Intel DC P3700 [4, 5] comes in at a whopping $4828 already. Suddenly M.2 based solutions don’t seem all that bad- especially given the lack of bulky connectors!
[…] rage lately in storage has been breaking the SATA barrier with M.2, SFF-8639 [1] and PCI-E slot based devices. G.Skill has joined in the fray by announcing the Phoenix Blade PCI-E […]
