Tom
Coughlin, President, has been working for over 20 years in the data storage
field at Ampex, Polaroid, Maxtor, Seagate, 3M and other companies. He has over
40 publications to his credit. Coughlin Associates provides Data Storage
Consulting services.

editor's comments:- Tom Coughlin has organized many storage events -
including the annual Storage Visions
Conference . His market reports used to focus on the HDD market - but in
the past 4 years more of these reports have also been about SSDs.

| Coughlin Associates
cofounds Drive Trust Alliance |
Editor:- August 10, 2015 - if you didn't think
there were already enough ORGs
related to the storage market - then a new one today has been proposed by
Coughlin
Associates and (new to me) Bright
Plaza, Inc.
The Drive
Trust Alliance at http://www.drivetrust.com (which currently redirects
to http://www.brightplaza.com/products/#tdta) is "an alliance of companies,
organizations, and individuals that will benefit from cost efficiencies in
marketing on-going education and the creation and support of open source
software for managing Self-Encrypted Drives".

How
Many IOPS Do You Really Need? - is a new 80 page SSD market report
($5,000) by Objective
Analysis and Coughlin Associates
which dissects the results of a months-long on-line survey of IT managers which
collected their inputs on the IOPS, capacity, and latency needs for a number of
key enterprise applications. | | |

| there was a flash memory
bard |
Editor:- August 24, 2016 - In case you missed it
- there were a LOT of
entries
in the Flash Memory Limerick competition organised by NVMdurance.
The
draw winner - announced
at the Flash Memory Summit -
was Tom
Coughlin, President Coughlin Associates.
You
can read Tom's winning entry and many other fine examples from people in the
SSD industry who have invented many playful ways to link the ideas of
endurance, flash, SSDs and even business development themes in unique ways
that have never before been seen in
SSD history.

software slows new silicon in memory done by SSDs |
Editor:- February 5, 2014 - In a new blog -
New
Vistas For Persistent Memory - Tom Coughlin,
President Coughlin
Associates reminds us that in exteremely fast SSDs - lowering the
hardware latency is just one part of the design solution.
Tom says -
"An important element in using persistent memory in the PCIe and memory
bus of computers is the creation of software programs that take advantage of the
speed and low latency of nonvolatile memory. With the increase in performance
that new interfaces allow, software built around slower storage technologies
becomes a significant issue preventing getting the full performance from a
persistent memory system."
Tom's article includes a graph which
shows the increasing proportion of the read access time taken up by system
software in successively faster hardware interface generations. ...read

Editor's comments:- living with the old
while planning for a new type of SSD-aware computer architecture is
complicated.
Just how complicated that picture can be... you may
glimpse in a classic far reaching paper (about abstracting application
transactional semantics in usefully different ways when viewed from their
interactions with the flash translation layer) - called
Optimizing I/O
Operations via the Flash Translation Layer (pdf) by Gary Orenstein,
Fusion-io (August
2011). | | |
