the SSD Buyers Guide - by Zsolt Kerekes, editor

I currently track and talk to over 300 SSD companies who design products (from chips to rackmounts) in the enterprise, military, industrial and consumer solid state drive markets - from stealth mode startups (sometimes before the founders incorporate their company) to the world's oldest and most successful SSD makers.

I'm like the Old Woman of the SSD Village who talks to everyone that passes through. No wonder I have a unique perspective. It would be strange if I didn't.

RunCore announced it is shipping a 7mm high, Sandforce-based, 2.5" SATA 3 SSD for the high performance Ultrabook market.

IP-Maker released a data transfer manager core - for use in PCIe SSDs - the 1st design to be compliant with the NVM Express specification.

Micron announced it has acquired the assets of UK based Virtensys which marketed rackmount SSDs stuffed with Micron's PCIe SSDs and supported by a patented multi-server sharing virtualization interface.

OCZ demonstrated new PCIe SSDs - which use SSD controllers jointly developed with Marvell (instead of - as in previous models - controllers from SandForce).

Samsung entered the fast purge SSD market - which currently numbers about 25 companies. The company says that models of its PM810 2.5" SATA SSD family with its Crypto Erase technology deletes targeted data in a couple of seconds regardless of the overall volume of data or the capacity of the SSD. These models have been validated for compliance to NIST FIPS 140-2

pureSilicon launched a 1.6TB usable (2TB raw) 2.5" SATA eMLC SSD. The Nitro N2 has average latency under 100 micro-seconds, R/W speeds upto 540/520 MB/s and upto 130k random IOPS. The N2 uses a proprietary design and is protected against sudden power loss.

Fusion-io exceeded 1 billion IOPS (64 byte data packets) in a configuration which used 8 HP servers each configured with 8x ioDrive2 Duo PCIe SSD - in a historic demo this month showing the capabilities of its latency reducing Auto Commit Memory (ACM) extension.

Huawei Symantec published an SPC Benchmark report (66 pages pdf) for its high availability FC SAN rackmount SSD - the Oceanspace Dorado2100. A 1 terabyte (approx) usable protected (mirrored) SSD system (2.4TB raw) delivered over 100K SPC-1 IOPS at a market price of $0.90/SPC-1 IOPS.

Nimbus announced its entry into the high availability enterprise SSD market with the uveiling of the company's - E-Class systems - which are 2U rackmount SSDs with 10TB eMLC per U of usable capacity and no single point of failure. Interface support includes unified 10GbE, FC, and Infiniband. Pricing starts at $150K approx for a 10TB dual configuration system.
December 2011 - Apple acquires Anobit
Apple acquired Anobit for a sum thought to be in the range $400 to $500 million.

XtremIO secured a 2nd round of funding in December 2011 - from various source including Lightspeed Venture Partners - bringing its total funding upto $25 million.

OCZ reported preliminary revenue for the past quarter (ended November 30) to be in the range $100 and $105 million - an increase of approximately 90% compared to the year ago quarter and a 30% increase compared to the immediately preceding quarter. The company attributed much of this to its growing traction in the enterprise SSD market.

Texas Memory Systems announced imminent availability of the RamSan-720 - a 4 port (FC/IB) 1U rackmount SSD which provides 10TB of usable 2D (FPGA implemented) RAID protected and hot swappable - SLC capacity with 100/25 microseconds R/W latency (with all protections in place) delivering 400K IOPS (4KB), 5GB/s throughput - with no single point of failure (at $20K/TB approx list). And the company also announced that it was looking for a potential acquirer.

the flash SSD story - market survival of the fittest?
The emerging size of the flash SSD market as you see it today was by no means inevitable. It owes a lot to 3 competing storage media competitors which failed to evolve fast enough in the Darwinian jungle of the storage market in the past decade.

One of these 3 contenders is definitely on the road to extinction - but could one of the other 2 still emerge to threaten flash SSDs?

A recently published article - SSD's past phantom demons explores the latent market threats which hovered around the flash SSD market in the past decade. They seemed real and solid enough at the time.

Surviving SSD sudden power loss
Why should you care what happens in an SSD when the power goes down?

This important design feature - which barely rates a mention in most SSD datasheets and press releases - has a strong impact on SSD data integrity and operational reliability.

This article will help you understand why some SSDs which (work perfectly well in one type of application) might fail in others... even when the changes in the operational environment appear to be negligible.
