KIOXIA Shows Off New EDSFF SSD Form Factor Geared to Servers and Storage

KIOXIA has partnered with a leading server original equipment manufacturer (OEM) to successfully demonstrate an E3.S full-function development vehicle of the new EDSFF (Enterprise and Data Center Form Factor).  This breakthrough new form factor, also called E3, enables maximum system density, simplicity and efficiency.

KIOXIA is an active member of the SNIA SFF-TA-1008 technical workgroup, which has been instrumental in creating the new EDSFF E3. Short (E3.S) and E3.Long (E3.L) solutions, which are expected to be the future of SSD storage for All-Flash Arrays (AFAs) and servers in enterprise data centers and cloud applications.  Utilizing one common connector, this new form factor for PCIe-based devices, including NVMe SSDs, graphics processing units (GPUs) and network interface cards (NICs), provides a complete selection of capacity, power and footprint choices, enabling unprecedented system design flexibility.


These EDSFF E.3x drives go beyond the design limitations of the 2.5″ form factor by supporting better signal integrity and higher power requirements (up to 40W), and maximize the performance capabilities expected with PCIe Gen 5.0 and beyond to enable future generations of storage and server systems.  These future-forward SSD device designs also offer improved thermal characteristics that address the cooling concerns that have historically come with such game-changing performance.

According to Shigenori Yanagi, SSD Technology Executive for KIOXIA, “We are excited to work with the leading server and storage system developers to bring new classes of systems to market that will be able to fully unleash the power of flash memory, NVMe and PCIe.  EDSFF E.3S will power the future generations of servers and storage, making the data center even more efficient.”

The EDSFF full-function development vehicle created by KIOXIA is based on the E.3S thin (7.5mm) form factor and offers increased flash density per drive for optimizing rack consolidation and power efficiency.  These drives feature the same core components as KIOXIA’s recently-announced CM6 Series of PCIe 4.0 NVMe 1.4 SSDs and are configured with x8 PCIe lanes and up to 28W of power.  KIOXIA will also be supporting additional size/width options, such as E3.S thick (16.8mm) and E.3L thin.

SK hynix PE6011 Enterprise SSD Review

We last discussed SK hynix back in August as we looked into the history of the company and overviewed their Enterprise SSD solutions. Today we are reviewing and looking at the performance of the SK hynix Enterprise SSD the PE6011. The PE6011 features a U.2 7mm form factor, 3D TLC NAND, PCIe NVMe interface, and capacities up to 7.68 TB. It is ideal for read-intensive workloads and light write usage. What’s unique about this product is that from conceptualization to manufacturing everything is done in-house by SK hynix. This product is aimed at those looking for an economical PCIe solution for the datacenter environment. Looking at the design and build of this drive, the entirety of the casing is a polished silver. It is a 2.5″ drive with a U.2 connector and a form factor z-height of 7mm. Being 7mm lends a physically smaller footprint and gives this drive the ability to be equipped and fit in a large variety of things for universal appeal. Branding as well as unique identifying informa...

Kingston DC1000B SSD Review

The Kingston DC1000B is a read-focused M.2 NVMe SSD aimed at the market of on-board server boot drives. While the DC1000B is aimed at being a cost effective offering, it doesn’t skimp on features such as power-fail protection that buyers expect from enterprise-grade SSDs. Aside from being used as a boot SSD, the DC1000B is beefy enough and can be leveraged for caching and logging applications as well, with a 0.5 DWPD endurance rating and a 5 year warranty. The DC1000B ships in capacities of 240GB and 480GB. The DC1000B leverages 3D TLC NAND and the PCIe Gen3 x 4 NVMe interface to offer sequential read speeds topping 3.2GB/s. According to Kingston, the drive can hit up to 205K IOPS in 4K steady-state read at an average latency of 161?s. On the write side of performance, things are a bit lower, but this is expected. Top sequential write speed is 565MB/s, top steady-state 4K is 20K IOPS, and latency is only 75?s. In other highlights, the drive supports SED with AES 256-bit encryption. ...

Memblaze PBlaze5 920 Series NVMe SSD Review

We’ve seen numerous enterprise SSDs from Memblaze over the years, they’re often on the leading edge when it comes to both technology and performance. Recently they’ve launched a new set of SSDs in the Memblaze PBlaze5 family, the Memblaze PBlaze5 920 Series. The 916 Series before it, the PBlaze5 920 Series comes in U.2 and Add-in-Card (AIC) form factors. The biggest difference with the 920 Series is that it uses a new set of NAND, moving to 96-layer 3D TLC NAND from 64-layer in the prior model. At the top end, the new Memblaze SSDs are quoted to deliver 5.9GB/s and 970,000 IOPS at the top end of the performance spectrum. Memblaze PBlaze5 920 926 The 920 Series comes in two endurance ratings, either 1 drive write per day (DWPD) or 3 DWPD. This creates four distinct drives, segmented on form factor and endurance. The AIC form factors are designated as C920 and C926, with the C920 being the more read the centric drive and the C926 carrying that 3 DWPD endurance rating. Similarly, the U....
