Linux Driver Support Decoded

Written by Judith Vanderkay on . Posted in Blog

NVM Express has enjoyed Linux kernel support since early 2011. However, it is a complex landscape, and it can be challenging to understand all of the Linux Server OS and kernel choices, including when particular features have been adopted.

Learn all the details for kernel support and the various Linux distributions (Red Hat, Ubuntu, SUSE, and Oracle Linux) in this detailed overview by Frank Ober.

American Megatrends Inc. (AMI) Launches Enclosure Management Solution for NVM Express SSD Subsystems

Written by Judith Vanderkay on . Posted in Blog

The AMI MG9095, a new low-cost, ultra-small, single-chip solution for enclosure management, designed for a new generation of NVMe SSD environments, supports up to eight SSDs per backplane. However, cascaded controllers can support up to 32 drives. More details and specifications for the product can be found on the AMI corporate website at

Crystal Disk Mark’s New Release Measures True Performance of NVMe

Written by Judith Vanderkay on . Posted in Blog

Due to limited support for large queue depths and multiple workers, the full performance of NVMe SSDs could not be seen in Crystal Disk Mark 3.0.4 . For example, the maximum read bandwidth on this build for one NVMe drive was ~ 1.5 GB/s and the maximum IOPs was ~ 150K IOPs.

The developer has completed a new version, revision 4.0.3, that adds deeper queues and multiple worker threads to the benchmark and enables measurement of the true performance of an NVMe SSD. The same NVMe drive now measures over 2 GB/s for bandwidth and ~ 450K IOPs on random I/O. In order to fully saturate the NVMe drives, recommendations are a queue depth of at least 32 and a minimum of 8 worker threads for 4K random testing.  Check it out at

First NVMe All-members meeting, April 30

Written by Judith Vanderkay on . Posted in Blog

The NVM Express annual member meeting was held last week in San Jose, California with over 130 members joining in to get the latest updates.  During the meeting the group heard the latest status on technical working group activities and marketing plans, and discussed roadmaps and planning for this year’s upcoming events.  A networking event took place after the sessions.

As part of the after-hours social event, several companies demoed some of their latest NVMe products including;

  • HGST, Ultrastar SN100 & SN150 NVMe SSDs
  • OCZ, Z-Drive 6000 Dual port NVMe SSD
  • Mangstor & Melonox, NVMe over Fabric
  • Samsung, SM951 M.2 and XS1715 & SM1715 NVMe SSDs
  • Teledyne LeCroy, NVMe test equipment

Thanks again to all those who supported and attended.

Mass production of industry’s first M.2 NVMe PCIe SSDs begins

Written by Judith Vanderkay on . Posted in Blog

Samsung has started mass production of the industry’s first NVMe PCIe solid state drive (SSD), with an M.2 form factor for use in PCs and workstations. The company has also begun shipping NVMe SSDs to OEMs for the PC market.

According to the company, the new NVMe-based SM951 SSD achieves sequential data read and write performance up to 2,260 megabytes per second (MB/s) and 1,600MB/s, respectively, which Samsung states are the industry’s most advanced, with speeds four and three times faster than those of a typical SATA-based M.2 SSD.  Read more in the press release and in SSD Review.

Using NVMe to Modernize Servers, with Big ROI

Written by Judith Vanderkay on . Posted in Blog

Principled Technologies has done a deep analysis of the Lenovo ThinkServer RD650 with NVM Express SSDs. When the server is equipped with four 1.6TB NVM Express SSDs, it delivers the work of four legacy server workloads. Consolidating older servers onto a powerful new server with flexible storage solutions, including NVMe, can be an excellent investment. For all the details, check out the white paper here.

How to Benchmark SSDs with FIO Visualizer

Written by Judith Vanderkay on . Posted in Blog

There are two proven software tools commonly used for IO benchmarks – Iometer ( for Windows and FIO ( for Linux OS. 

What is FIO Visualizer? It’s a GUI for the FIO. It parses console output in real-time, displays visual details for IOPS, bandwidth and latency of each device’s workload. This is a valuable tool for benchmarking NVMe SSDs.

Learn all the details and how to get started here.
