the limericks of flash SSD endurance
this is the true
story of how a serious subject begat a bunch of rhymes and
a mention at
the 2016 Flash Memory Summit (see also:-
SSD market
history) | |
|
There was a young lady called Prudence
Was worried 'bout
flash's endurance
She met an IP
Who said - stick by me
My
software will be your ensurence |
|
| (the above limerick having been
inspired by reading about a company called NVMdurance) |

more about a limerick concerning SSD
endurance?

Last night - while not-quite watching tv - I saw
(via my
linkedin
connections) a note by Stephen Bates
at Microsemi
who commented on a post by Pearse
Coyle, CEO - NVMdurance
who was bringing attention to an article -
Memories
will be made of this (published in
SiliconRepublic)
in which Coyle is interviewed about his own SSD software company which is
in the flash
endurance stretching business.
When I saw that the roots of the company
lay in Limerick I was inspired to write something and I dashed off to the
kitchen to make a cup of tea. And while waiting for the water to boil the
complete verse just sprang out, line by line, just as you see it here above.
I
had intended to write more about NVMdurance's technology at some time although
this rhyme was not precisely the kind of thing I had in mind.
...Later:-
in the week following the above rhyme I spoke at length to NVMdurance's CEO -
Pearse Coyle - about the history of flash characterization and how it relates to
endurance and controller techniques.
I said that one aspect of this
reminded me of something another company had done 4 years earlier.
You
can see more about this conversation in my article -

machine learning to manual tuning |

|
| Once the limerick idea got in my
head. It stuck for a while. I returned to the subject soon after with this
apology |
|
Is it a crime?
That I wrote a rhyme
A diddle dee dee
About #SSD
It didn't take long
To knock out that song
I stirred it while boiling my tea |
|
| Here are some links to serious articles I've
written about SSD endurance |

Limericks at the Flash Memory Summit |
Editor:- May 5, 2016 - NVMdurance today
announced
a Flash
Memory Limerick competition the winner of which will be announced at the
Flash Memory Summit.
Editor's comments:- when I saw the
linkedin
post about this by Aisling
Foley at Aisling Foley Marketing
- I couldn't stop myself thinking...
 Aha!
- now I know more about NVMdurance's technology and the
5 stage life
cycle budget (pdf) it uses to dress the flash in a fashion which is age
appropriate - how can I get that in? |
The sages of flash now agree
That if you fall out of a tree
To increase your chances
Grab hold at five branches
And swing around judiciously |
Editor again - I still can't decide whether "grab
hold of" is better than "grab hold at".
One sounds
more natural while the other sounds forced but more accurately paints
the picture. But I'm not going to agonize over it any longer. And just to be
clear. I myself don't enter competitions. So your field is clear (of
mice anyway). | | |

there was a flash memory
bard
who said it's not really that hard
playing limerick sports
takes
less time than reports
as all the words fit on a card |
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.

have been promising they will soon replace flash. But alternative nvms
weren't the only threats which failed to make an appearance in the "kill
flash wars". |
