How Big will be the Market for PCI / PCIe SSDs?
This is a new emerging market so it's impossible to be precise.

But search volume based data reveals some useful comparisons.

In the 6 months leading up to November 1, 2008 - the most popular SSD form factors viewed by readers on storagesearch.com were in order:- 2.5", 3.5", 1.8" and PCIe.

Approximately 10% of all SSD readers in that period viewed this PCIe SSD page.

Another clue is that 2 of the top 10 SSD oems (based on reader volume in Q3 2008) only marketed PCIe connected SSDs (in that quarter).

There's little doubt that the availability of PCIe SSDs will bring new customers into the server acceleration SSD market.

The PCIe SSD approach suits a Google architecture - in which the applications infrastructure consists of large numbers of democratically equal powered servers.

The traditional FC-SAN SSD approach fits in better with a heirerarchical applications infrastructure - with a lean top and fat bottom. However, the servers at the bottom can also get speedup benefits from a DAS style SATA SSD implementation .

I think both SAN and PCIe SSDs will exist side by side for many years serving different types of application - even within the same enterprise.

PCI Express SSDs Technical Pros and Cons

The great attraction of PCIe for SSD oems
is that it can support a wide range of performance options with throughput upto 16GB/s, and much lower attachment costs than the alternatives.

The older busses like PCI and cPCI also provide performance which is adequate for many applications.

Bus connected SSDs have been around since the earliest days of the SSD market.

The advantage of this approach is high throughput and low latency compared to SSDs connected via traditional hard disk style interfaces like SAS, SATA, fibre-channel or InfiniBand.

But there are disadvantages too which include:-

1 - Bus style interfaces reduce the available market for the SSD oem. Because older servers may not have the interface, or perhaps the interface (for example Sun's SBus) is proprietary and is only available in a small range of models.

2 - Bus interfaces tend to have shorter permissable cable lengths - which restrict how such SSDs can be connected.

3 - Bus interfaces usually don't include intrinsic end to end error detection and correction. If the physical arrangement of the SSD pushes the speed and cable lengths too far - then errors can arise in the bus connect - which have to be dealt with in the associated driver.

PCIe, PCI etc Extracts from SSD History
January 2009

StorageSearch.com disclosed that in the 1st 3 weeks of January pageviews for PCIe SSDs had overtaken 1.8" SSDs, and 3.5" SSDs too, placing them at #2 in search destination popularity behind 2.5" SSDs.


December 2008

StorageSearch.com disclosed that PCIe SSDs had risen into the top 10 subjects viewed by readers in November.


November 2008

Violin Memory announced availability of a new 1010 Memory Appliance - a fast 4TB SLC flash SSD in a 2U rackmount. Its patent pending non blocking architecture delivers over 200K random Read IOPS and 100K random Write IOPS (4K block). Interface options include:- PCIe, Fibre Channel and Ethernet.

Micron Technology demonstrated prototypes of fast PCIe flash SSDs with 800MB/s throughput, and hinted that it might demonstrate 1GB/s SSDs soon.


October 2008

Virtium Technology entered the SSD market with its LeanSTOR - an AMC form factor SSD module for the AdvancedTCA market.

Other AMC/ PMC SSD oems include:- Aitech Defense Systems, Asine, BiTMICRO Networks, Curtiss-Wright, INTELLIAM, Micro Memory and Vanguard Rugged Storage.


September 2008

Fusion-io unveiled the ioSAN - a 10GbE or Infiniband attached flash SSD on PCIe form factor which will ship in 2009.


August 2008

Violin Memory said it had delivered 1 million IOPS on a single interface port (a world record) using the latest version of its Violin 1010 memory appliance. - Violin also said that its new technology would deliver 100K write IOPS on a flash SSD version of their product (which hasn't been announced yet.)

Fusion-io added RAID protection to the flash memory array in its Fusion-io PCIe SSD and improved R/W performance.




June 2008
