<>A long absence of power to affect refreshes of solid state storage
can still render solid state storage unusable, while true disks don't
need refreshing to maintain the content.
There are some shops, in the Greater Toronto Area, using them in production.
----------------------------------<unsnip>--------------------------------------
I was once in a shop that used them in production as well. As LOCAL page
devices. The level of trust just wasn't there to allow any other usage.
------------------------------------<snip>----------------------------------<>
Also, power surges and vagaries in supply voltage and/or current levels are
less likely to affect a hard drive, even though the cirtuitry to avoid these
vagaries is becoming more and more prevalent today.
UPS and power conditioning come to mind.
Who powers their data centre straight from the grid, these days?
-----------------------------------<unsnip>---------------------------------
I thinkk you'll find a significant, though maybe not large, number of
shops running straight from the grid today. For those shops, the cost of
an outage may be lower than the cost of power conditioning and/or UPS
equipment. Let's face it, not all "business decisions" make good sense,
in spite of what we'd all like to think.

<>Can we all remember the STC "Solid State Disk"? And manufacturing
vagaries can still have severe and detrimental effects on solid-state
memory, whereas the manufacture of magnetic disks is fairly well
solidified today, except for incremental changes that affect capacity.
Then stop using Cache and CPU memory.
It's the same chipsets, in most cases.
----------------------------------------<unsnip>--------------------------------
The chip design may be the same, but are the manufacturing facilities up
to the same quality control standards? More and more "makers" doesn't
always mean equal quality across the board. The the firm of "Dewey
Cheatem & How" have the same standards as, for example, INTEL? To
survive, the prices have to be competitive and so does the quality. And
how many managerial-types will look at a lower price and make their
decisions based entirely on price? Every business has its share of
airheads and IT is certainly no exception.
-----------------------------------------<snip>-------------------------------------<>
I predict that magnetic disk technology will bbe with us for the foreseeable
future.
No more than two or three mainframes will ever be sold.
Nobody will ever need more than 640K of memory.
-----------------------------------------<unsnip>----------------------------------
Yeah, we've all heard those predictions and seen just how incredibly
wrong they were. I might be just as wrong. Only time will tell. :-)

Too busy driving to stop for gas!
--------------------------------------<unsnip>-------------------------------------
You've been saying that for as long as I can remember. Eat lots of beans
and you don't need to stop for gas! :-))
