What if you buy two, use one for a complete backup and the other for
incrementals or differentials? (I know, more than $200...)
My disastrous experience with the last pair of seagates preclude
exploring that path, ever again. I bought a couple 2T's to replace 2
1T's I had outgrown and had close to 70,000 spining hours on the. They
lasted a bit less than 30 days, dropping off the sata cables connecting
then, never to be found again. Then I find they were shingled tech, and
helium filled so the heads flew lower.
But I have experience with helium in large car load qty's of it and in
30 days I can guarantee those drives no longer had any Helium in them if
there was any positive pressure inside them. This was about a year after
JFK launched his effort to put men on the moon the first time.
A bank of 16 monel bottles, each about a foot in diameter and maybe 12
feet long, pumped up to about 7500 psia for the night at midnight at
Stellardyne labs in Sandy Eggo while testing the atlas stuff that gave
John Glenn his 1st full orbital ride, were down to around 5800 psia at 8
the next morning when the day shift got there. The Helium atom is so
small it creeps between the atoms of tha monel, the best alloy for that.
and heads for outer space never to be seen again.
And that was considered normal, and better thn the 50,000 gallon steel
tank that caught and recyled the test cells output, we had a 6 stage
cardox compress in the back yard that suck from that big tank and put it
back on those monel bottles. With a guvmnt truck bringing in new to
replace it 2x a week. In those days the guv automatically owned any
helium recovered from deep in mines by air reduction techniques. It's a
precious commodity, worth close to $100,000 a truckload in $1.75 min
wage days. When its gone, its gone and we will exhaust the planets
supply by filling party balloons with it. Filling hard drives with it to
make the heads fly lower is idiocy. Regardless of how thick you cast the
alu or pot metal of a drive housing, it will be gone much quicker than
those monel bottles allowed.
They (Seagate) could have gotten a longer term lower head fly by sealing
them up in a vacuum equ to the top of Everest.
Like Albert Eintsein said, the 2 most common things in the universe are
stupidity and hydrogen, in that order.
You may not have arrived yet Karl, but I was there, busy testing the
fuel pressure regulators for Atlas rockets and keeping my wife barefoot
and pregnant, her choice for both.
Take care, stay warm, dry and well Karl.
Cheers, Gene Heskett.
