  • editor's comments:- in May 2010 - PMC-Sierra entered the SSD market by announcing a definitive agreement to acquire Adaptec's channel storage business for approximately $34 million in cash. This deal includes Adaptec's RAID storage product line, its global VAR customer base, board logistics capabilities, and (most significantly) SSD cache performance solutions.

    In my storage market outlook 2010 to 2015 article - published last year - I explained why I thought that the enterprise RAID controller market couldn't stay as it was.

    These companies have to get into offering complete SSD solutions in the long term. In the short term PMC-Sierra may be able to do a better job aggregating a bigger percentage of whatever remains of the untied RAID controller business.

    I expect the RAID business (for hard disks) will eventually become a consumer / SMB market - while the enterprise storage array part of this market will morph through an SSD ASAP phase - while users struggle to redefine new storage architectures for the datacenter.

how fast can your SSD run backwards?
SSDs are complex devices and there's a lot of mysterious behavior which isn't fully revealed by benchmarks and vendor's product datasheets and whitepapers. Underlying all the important aspects of SSD behavior are asymmetries which arise from the intrinsic technologies and architecture inside the SSD.

Which symmetries are most important in an SSD?

That depends on your application. But knowing that these symmetries exist, what they are, and judging how your selected SSD compares will give you new insights into SSD performance, cost and reliability.

There's no such thing as - the perfect SSD - existing in the market today - but the SSD symmetry list helps you to understand where any SSD in any memory technology stands relative to the ideal.
SSD symmetries article And it explains why deviations from the ideal can matter. to read the article
