Editor's intro:- The 2.5 inch form factor is the hottest part of the solid state disk market - with new oems entering the market every month during the past year. At stake are multibillion dollar market segments for 3 of the 4 primary applications described in detail in our SSD Market Adoption Model. These will add up to a $10 billion / year SSD market within a few years.

The 2.5" form factor is the only size which straddles the wide range of SSD application slots.

The technical characteristics of the ideal 2.5" SSD product varies considerably from design slot to design slot (sometimes raw speed, othertimes capacity, reliability, TCO, initial price or power consumption). These are often conflicting parameters and cannot be met by any single product. However, the overlap of capability and technology between some high volume applications and the sheer number of oems guarantees a very competitive market - a from which users will benefit much sooner than predicted by out of date graph theory projections proposed by classical storage analysts.

As with all the tables on STORAGEsearch.com the data in this reference article is updated in real-time to reflect changes in the market.

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", 832G 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
