Phison shows new enterprise NVMe SSD controller supporting TLC

CES 2015 -Phison is poised to make waves with their new PS5007-E7 controller. This new controller will power enterprise NVMe SSDs in both the M.2 and 2.5" form factors, with the latter sporting the new SFF-8639 connector. The controller will provide plenty of bandwidth with a PCIe 3.0 x4 connection. The new controllers support capacities from 16GB all the way up to 2TB. Sequential reads are rated for 2,800 MB/s, and sequential writes come in at 1,500 MB/s. The controller also features random read/write speeds of 350,000/300,000 IOPS.




The controller supports both AHCI 1.3 and NVMe 1.1 (covered in our Defining NVMe article). Current designs do not include power capacitors, but power loss protection will be included in the final designs. It is also only rational that an NVMe controller with this type of grunt power will eventually make its way to a standard PCIe form factor product, but we did not receive official confirmation of that possibility. The M.2 form factor is starting to pop up in roadmaps of more manufacturers for enterprise applications, so there is definitely an emerging customer base for these products as well.

OCZ Storage Solutions Z-Drive 6000 NVMe SSD on display at CES 2015

CES 2015 -OCZ Storage Solutions displayed the Z-Drive 6000 NVMe SSD in their suite at CES 2015. The Z-Drive 6000 sports speeds of 3,000 MB/s for sequential read and 2,000 MB/s for sequential write workloads. Random reads weigh in at an outstanding 700,000 IOPS, and random writes are equally impressive at 175,000 IOPS. The Z-Drive 6000 will provide 1-3 DWPD, which is becoming the standard for most datacenter SSDs, largely due to increased density. The Z-Drive 6000 utilizes the NVMe interface, covered in detail in our Defining NVMe article.




The Z-Drive 6000 comes in capacities of 800GB, 1.6TB and 3.2TB in the small 2.5" 15mm form factor. The Z-Drive leverages the proven PMC-Sierra Princeton controller running OCZ-proprietary firmware. The Z-Drive 6000 is certified for NVMe specification 1.1b on the UNH-IOL integrator list. The drive also features all the normal enterprise trimmings, such as encryption and internal data redundancy.

Samsung displays cutting-edge TLC 3D V-NAND wafers at CES 2015

CES 2015 -Samsung has the advantage, for the time being, of being the only manufacturer shipping 3D NAND products. V-NAND is 3D NAND that achieves better density, performance, endurance, and power consumption, via vertical stacking of the NAND cells and CTF technology. This runs counter to the established norm of increasing density through NAND shrinks, and with good reason. Shrinks provide more density, but actually reduce endurance.




We have a more detailed analysis of V-NAND in The V-NAND Paradigm Shift article. Samsung has the 10nm class MLC NAND 16Gb and the 32-layer 128Gb TLC 3D V-NAND on display. The TLC (or 3bit) versions of V-NAND boost capacity, and also provide increased endurance in comparison to standard planar TLC NAND. Planar TLC has already made its way into the client and enterprise space despite the lower endurance, and 3D TLC V-NAND is on the way to the datacenter as well.

Seagate displays Kinetic Ethernet-connected HDDs at CES 2015

CES 2015 -HDDs are evolving to address new challenges in the datacenter, and the Seagate Kinetic line offers a radical new way of improving performance and reducing TCO. Hyperscale customers are constantly looking for refined systems to lower operating costs, and new data storage methods to address the massive influx of data.




Kinetic drives interact with an open-source Seagate-developed API that eschews the normal filesystem implementations in favor of the more robust Key/Value Object storage. The Kinetic platform also dramatically reduces host overhead and removes CPU processing from the majority of tasks.

Marvell displays their new, and incredibly small, NVMe SSD controllers

Storage Visions 2015 -Mike Chen from Marvell stopped by the TweakTown booth at Storage Visions 2015 to display the Altaplus controller along with a new SSD that has an integrated controller on the NAND package. NVMe has several performance advantages, but also enables low power operation modes particularly well-suited for mobile applications. Marvell is delivering both PCIe 2.0 and 3.0 SSD controllers that feature robust LDPC error correction technology.





There are multiple lengths in the M.2 standard, and here we can see the difference in size between the different solutions.

NVDIMM SIG representatives discuss the future of NVDIMM technology

Storage Visions 2015 -Arthur Sainio from Smart Modular Technologies and Mario Martinez from Netlist stopped by the TweakTown booth to discuss emerging NVDIMM technologies. SNIA's NVDIMM Special Interest Group (NVDIMM SIG) works hand in hand with JEDEC, who develops the NVDIMM Specification, to promote the new technology.



Flash has revolutionized datacenter storage, but NVDIMM technology takes performance to the next level. NVDIMM's leverage DRAM in conjunction with flash storage and power hold-up technologies to allow RAM to be used as a persistent storage medium. This opens up new opportunities to accelerate application performance.
