SSD maker OCZ has been on something of a tear recently, introducing three new solid state storage products in three weeks:
- Two weeks ago the company introduced the Z-Drive R4 CloudServ PCIe SSD, designed for the data center, in single-card capacities ranging from 300GB-16TB. This product can transfer data at multiple gigabytes per second rates to deliver over a million IOPS.
- Last week saw the introduction of the OCZ-SANRAD VXL enterprise storage accelerator, after OCZ’s January acquisition of SANRAD. This product is flash cache acceleration software for VMware ESX and Citrix Xen virtualized environments that allows Continue reading “OCZ: Three Solid State Storage Products in Three Weeks”
The SSD Guy has just posted a new white paper to the Objective Analysis home page. It’s about Kaminario‘s approach to solid state storage.
Yes, this is a commissioned white paper, but that doesn’t preclude my taking the same unbiased approach my clients have come to expect. Kaminario has re-thought how SSDs should be used in storage, and that deserves some attention.
It’s only six pages, but even so I will condense the content for this post: Flash is tricky Continue reading “New White Paper: Enterprise Reliability, Solid State Speed”
Today Hitachi announced the company’s second generation Ultrastar SSD400S.B family, which Hitachi claims to be the industry’s first 25nm SLC enterprise-class SSD family.
This comes only two days after Intel announced a 25nm MLC SSD – Intel‘s highest-performance SSD to date.
The new Hitachi SSDs support a SAS 6Gb/s dual port interface. SLC NAND flash was chosen for its high write performance and endurance.
Maximum sequential read speeds of 536MB/s and a sequential write speed of up to 520MB/s with 57K random read IOPS and 25K random write IOPS help to give ultra-fast access to data.

Intel has announced a new SSD for the Enthusiast/Gamer market. Intel’s fastest drive to date, this SSD, formerly known as “Cherryville” but now called the 520, is the first Intel SSD to use a SandForce/LSI controller and is made using Intel’s own 25nm flash.
Intel worked with SandForce for a year and a half to produce an SSD that met Intel’s rigorous standards, and made hundreds of changes to SandForce’s firmware. Users of SandForce controllers can differentiate their SSDs through the addition of features in the SSD controller’s firmware. Intel did this by tapping into its expertise in end-to-end data protection (something the company learned when working with Hitachi to introduce that company’s Intel-based enterprise SSDs) while harnessing Intel’s deep understanding of its own NAND flash and of the I/O needs of the PC.
End-to-end data protection is not a trivial feature: Continue reading “Fast New Intel SSD: The 520”
At The Consumer Electronics Show this week, Swiss army knife maker Victorinox introduced a one-terabyte SSD in a form factor similar to a fat Swiss army knife. Yes, that is right – a terabyte of NAND flash in your pocket. The company tells us that the device’s dimensions, including the connector, are a scant 52x18x10mm.
Some of the other features include the use of an eSATA connector (to allow the product to be plugged into either a SATA port or a USB socket), AES256 encryption (any army would like this), and a bi-stable LCD to tell how much free space remains on the device.
But let’s look at the difficulty of building a 1TB flash SSD in such a small space:

Last night (1/5/12) at a DEMO Enterprise event in San Francisco Fusion-io unveiled a one billion IOPS (I/Os per second) storage system. A billion IOPS!
The machine was built using 64 Fusion-io ioDrive2 Duos connected to eight HP ProLiant DL370 servers.
This came sooner than we anticipated. It was only in July 2008 that the million-IOPS barrier was broken by IBM using 41 Fusion-io devices.

At Oracle’s October OpenWorld conference in San Francisco more exhibit hall space was dedicated to SSDs this year than ever before. That’s because Oracle runs faster on systems with SSDs than on systems without.
Even Oracle ships SSDs in its popular Exadata system, and the company recently announced that it had shipped over 1,000 installations since its introduction in 2009. Continue reading “SSD Presence Growing at Oracle OpenWorld”
On Tuesday, November 1, Seagate announced improvements to its flagship Barracuda line of 3.5″ HDDs for the desktop.
- The 5,900 RPM Barracuda Green will be discontinued in February
- The 7,200 RPM Barracuda XT will be re-named the Barracuda (without the XT designation, which indicates a “top of the line” speed)
- A new Barracuda XT line will be introduced at a later date and it will incorporate the hybrid design Seagate pioneered in the popular Momentus XT.
Capacities will range from 250GB-3TB. Continue reading “Seagate’s Barracuda to Add Hybrids”
