SSD Article Pageviews Grow 98%

Editor:- June 1, 2009 - StorageSearch.com disclosed today that page views for the popular SSD Buyers Guide increased 65% in May 2009 compared to the year ago period.

Average page views of the top 5 SSD articles in May 2009 were 98% higher than the top 5 SSD articles a year ago.

The #1 incoming search word to the mouse site was "SSD" which occurred 2.4x as often as a year ago. These metrics indicate continued growth in reader activity related to the SSD market despite the recession.

"Nearly every IT publication now has something to say about SSDs" says StorageSearch.com's editor, Zsolt Kerekes. "The SSD content explosion includes a lot of froth and inaccurate analysis - but also a lot of good stuff too. The best of the these get honorable mentions in the SSD Bookmarks. It's nice to know that despite the intense competition for SSD readers - we're still maintaining nearly triple percentage digit growth. Thanks to all our readers and those who link here for helping to make this happen. There's no shortage of ideas for new original SSD articles. In the past year nearly 1 in 3 new articles got abandoned mid way through editing because something more significant swept them away."


DDRdrive Launches Low Cost PCIe RAM SSD

Editor:- May 4, 2009 - DDRdrive emerged from stealth mode and launched the DDRdrive X1 - a PCIe compatible RAM SSD with onboard flash backup.

Load / restore time is 60S. I/O performance is over 200K IOPS (for 512B blocks). For 4kB blocks IOPS is:- 50k (reads) and 35K (writes). R/W throughput is 215MB/s and 155MB/s respectively. Capacity is 4GB. OS compatibility:- Microsoft Windows (various). Price is $1,495.

Using Microsoft Windows built-in RAID support, DDRdrive X1's can be spanned (capacity), striped (performance), mirrored (redundancy), and RAID-5 configured.

Editor's comments:- the DDRdrive X1 looks competitively priced for accelerating database applications in which the hot files can be squeezed into a capacity range from about 4GB to 12GB. Above that - you get into the region of entry level rackmount SSDs and high performance PCIe flash SSD cards from companies like Fusion-io and Texas Memory Systems.

There's definitely a gap in the market for this scale of product (low entry price, low capacity - high IOPS). For the past year or so DDRdrive shipped an earlier generation of its SSD accelerators exclusively to a large enterprise for secret internal projects.

This is a company whose revenue grew 400% in 2008 and whose customers include Samsung Securities. So you may be surprised what Tomas Havrda has to say on the subject of flash SSDs for enterprise acceleration. He's not convinced it's a good idea.


New Edition of the Top 10 SSD OEMs Signals New Paradigm

Editor:- April 1, 2009 - StorageSearch.com today published a new edition of - the Top 10 SSD OEMs.

In the past 8 quarters this popular feature has tracked the storage searches of more than 2 million SSD readers.

"Search volume based rankings of vendors in fast growing markets has proved to be an important predictor of future market behavior" said editor, Zsolt Kerekes who has been publishing enterprise IT directories online since 1996. "That's because the biggest enterprise buyers research new suppliers and technologies up to several quarters in advance of purchasing new systems. Interpreting the shifting signals from such a large and strategic focus group can provide valuable insights into what will happen in the market a year or more ahead."

There's something significantly different about the new #1 company. ...read the article


SSD Bookmarks from Texas Memory Systems

Editor:- March 16, 2009 - Texas Memory Systems' President, Woody Hutsell - shares his SSD Bookmarks today on the home page of StorageSearch.com.

Those who know the SSD industry well, mostly think of TMS as a company which makes very fast SSDs for accelerating SAN resident applications. But in the many discussions I've had with Woody Hutsell during the past decade - "reliability" has also been a frequent topic in our conversations.

That's because when you manufacture products which pack more memory chips than anyone else has ever put into a single box - all those "10 to the minus something" numbers which relate physics to semiconductor memory effects - add up to design problems which are far from theoretical. TMS has been engineering solid state storage systems for 30 years. So I was not surprised to see an in depth paper about reliability being one of the articles in this list of bookmarks.

DTS Launches Fastest 3.5" SATA SSD

San Jose, CA - February 17, 2009 - DTS, Inc today announced availability of the fastest 3.5" SATA SSD - the Platinum HDD 2009 model.

Internally it has a 1GB RAM SSD which operates as a non volatile RAM cache for an internal flash SSD (320GB to 512GB). Aimed at server acceleration applications performance is 25,000 R/W IOPS, read speed is 250MB/s, and write speed is upto 240MB/s. DTS says the huge nv cache also attenuates writes (the opposite of write amplification) - thereby reducing flash wear by x10 to x400 compared to conventional flash SSDs. ...DTS profile

Editor's comments:-
in my article Predicting Future Flash SSD Performance I noted how having a non volatile RAM cache is a key architectural factor in flash SSD tune ups.

In the rackmount SSD segment the RamSan-500 from Texas Memory Systems (launched September 2007) and in the 2.5" form factor the ESSD from Memoright are other examples of this type of implementation.

DTS's original Platinum drive (launched a year ago) was a hard disk / RAM SSD hybrid. The new 2009 model benefits from the faster IOPS performance which stems from embedding a flash SSD instead of HDD. It also builds on the experience of refining the internal cache which accelerates many types of server app - without any modification to the application software. You just install it like a hard drive. DTS says it's particularly good for VMware and similar multiple client environments. Their website includes comparative benchmarks.


New Directory - SAS SSDs

Editor:- January 26, 2009 - StorageSearch.com today published a new article and directory on the subject of SAS SSDs.

This market has been a long time acoming - and for many years there were only 1 or 2 vendors in the market. The new article chronicles the genesis of SAS SSDs and lists known vendors - which will head into double digits this year.


RamSan SSD Revenue Grew 20% in 2008

Houston, Texas - January 20, 2009 - Texas Memory Systems today announced that revenue from sales of its RamSan line of SSD products grew 20% in 2008.

The company also recorded record 4th quarter sales.

"We feared the global financial crisis and increasing competition would have a bigger impact on our 2008 results," said Woody Hutsell, Executive VP at TMS. "However, our solid state disks are often used in mission-critical applications and, in such applications, customers value Texas Memory Systems' engineering experience and 30-year longevity. Savvy IT managers will always be reluctant to put their critical data on a first generation product, whether it comes from a Fortune 500 company or a venture-funded startup."

"We are cautiously optimistic about 2009," continued Mr. Hutsell. "Solid state disks are an important part of modern telecommunications systems, financial exchanges, national defense systems and 'green IT' initiatives which are likely to benefit from new government investment. Additionally, a solid state disk can cost-effectively extend the life of existing IT infrastructure allowing cash-strapped IT managers to postpone major purchases." ...Texas Memory Systems profile

Editor's comments:-
while 20% annual revenue growth is indeed impressive - it nevertheless represents a slow down for TMS, which in some earlier years had reported growth rates between 45% and 80%.

One factor may be that in the past year the server acceleration market has become very competitive. Nearly 30 oems market rackmount SSDs - and if you add in the SSD speedsters from the 2.5" and PCI Express SSD markets you'll easily tot up more than 40 companies seriously competing in the space where Texas Memory Systems operates. Given those factors - and the recession - 20% revenue growth for TMS indicates a strong brand and product line.

In my article - Is the SSD Market Recession-Proof? (published July 2008) - I said "Overall a recession will be good for vendors of faster server oriented SSDs (both flash and RAM based) - but a recession will be bad for vendors of notebook SSDs." My many recent discussions with SSD vendors (and the press release from TMS today) seem to confirm this.

Solid Access Launches World's Fastest 1U Rackmount SSD

Austin, TX - November 17, 2008 - At SC08 today Solid Access Technologies announced the immediate availability of its new generation of DRAM SSD products, the USSD Series 300.

Solid Access says the 4 new models are aimed at organizations requiring the highest capacity, "no compromises" IOPS and data bandwidth performance in the smallest possible footprint. Interface options within the family include 8Gbps Fibre Channel, 6Gbps SAS and 320MB/s LVD SCSI interfaces. R/W latency is under 10 microseconds and the models support upto 100K IOPS on a single port.
  • Model 310 is a 256GB, 1U rackmount offering for high IOPS needs
  • Model 310T is a 1TB, 4U tower, targeted at high performance databases
  • Model 315 is a combined server and 128GB RAM SSD, 1U device, for custom projects
  • Model 320, a 256GB, 2U product which supports upto 6 ports and 4GB/s sustained aggregated data bandwidth.
Solid Access says it guarantees equivalent or better application I/O acceleration as well as the lowest price of any comparable SSD, and has launched a "test before you buy" program.

"Five years ago when we introduced the first open architecture, ultra-fast DRAM SSD, our goal was to offer the best performance, most flexible interfacing, highest density and best price of any offering in the segment" said Tomas Havrda, Solid Access Managing Director. "The new USSD 300 Series is the capstone to our efforts in a year in which we have enjoyed 500% growth. The recent 28 unit USSD sale to Samsung Securities is further proof that customers of all sizes are taking notice." ...Solid Access Technologies profile

Editor's comments:-
for several years there has been a gap in the market for a really high performance 1U rackmount SSD. My gut feeling is it could become a very popular form factor in Google style (democratic) server architectures - which contain large numbers of identical servers..

As the cost of RAM SSDs easily makes them the most expensive box per rackmount unit in the datacenter - the availability of 1U models reduces the incremental deployment costs for customers who are continuously upgrading their systems. It also lowers the cost of holding immediately deployable spares.

When flash SSDs aren't fast enough!

RAM based SSDs
are the original type of solid state disk and have been around for decades.

They rely on batteries to retain data when power is lost. Most models also include internal hard disk drives to which data is saved under battery power, so that data is not lost when the battery runs down. This hybrid technology means that RAM based SSDs are more bulky than flash counterparts and RAM SSDs are unable to operate in the same range of hostile environments.

RAM based SSDs are mostly used in enterprise server speedup applications. The fastest RAM SSDs are faster than the fastest flash SSDs. But for many server speedup applications F-SSDs are fast enough.

Unlike flash SSDs, RAM based SSDs never had restrictions on the number of write cycles. That made them more popular in enterprise acceleration applications in the past. But write endurance problems may be a thing of the past for flash.

Like hard disks - RAM SSDs have symmetric read/write IOPS. That's another big difference between RAM and flash SSDs.

The fastest flash SSDs available in 2007 had narrowed the gap between R/W IOPS down to 10 to 1 (from over 50 to 1). And in 2008 - a small number flash SSD systems achieved 1 to 1. But random R/W IOPS for RAM SSDs, and latency are still an order of magnitude faster than the best flash SSDs.

There are also some non volatile memory products such as PRAM, FRAM and RRAM which are replacing flash in industrial applications - and which already offer 1 to 1 read/write performance. But their capacity is 2 orders of magnitude too low to be of use in server applications.

RAM SSDs cost about 25x as much as flash SSDs (based on pricing data for 3.5" form factor February 2008.)

The ideal choice of SSD depends on the specific server and application environment and cost / benefit analysis.

For example - a fibre-channel SSD that doubles the performance of a 100 server network may be overkill if your application runs on a single server box which could be speeded up by directly attached SSD storage.

SSD Myths and Legends - "write endurance"
Does the fatal gene of "write endurance" built into flash solid state disks prevent their deployment in intensive server acceleration applications - such as RAID systems?
It was certainly true as little as a few years ago.

What's the risk with today's devices?

This article looks at the current generation of products and calculates how much (or how little) you should be worried.
read the article - SSD Myths and Legends
RAM based SSDs have been used alongside RAID for years - but flash SSDs are physically smaller and have bigger capacity (upto 412G in 2.5", 512G in 3.5") and are lower cost than RAM-SSDs and could actually be configured in standard RAID boxes. F-SSDs aren't as fast as RAM based products but a single flash SSD can deliver 20,000 IOPs - which when scaled up in an array - starts to look interesting. ...read the article, storage reliability solid state disks
