Subject: Re: PATA hard disks, anyone?
Digging around on the pointer from Al to backblaze, I found this, which,
to me is far more meaningful in terms of presentation of data:
Interesting but consistent with my informal observations. My Hitachi enterprise class 4gb
hdd are still going strong after multiple power outages and almost 5 years of 24x7 on
time. Granted not much reading and writing occurs but the fact that they are spinning is
probably the biggest wear and tear on them.
Helium drives? Only if you have the money to replace them yearly and have a RAID 1 set of
a RAID 6 volume....

I took a look at my 1TB drive stash. They're branded as Toshiba,
which,
I believe are really Hitachi. So maybe not so bad.
But on those charts, the 3TB Seagate really shows an astonishing failure
rate...

I recall at one company we used Micropolous ( SP? ) drives. We had almost 100% failure in
less than 6 months. It did our company a lot of damage.

A lot of outfits (e.g. Sun, HP) used Micropolis drives. Generally, they
were good, but expensive.
Maybe you're thinking of Miniscribe.

Micropolis quality dropped way down towards the end - at Dreamworks we used
to refer to it as "Micropolis - for all your data loss needs"

I have a couple of applications where I want the largest THIN 2.5" SATA
drive. Currently, that is the 2TB Seagate/Samsung.
2TB and up SSDs will be here. Eventually.
Comparing "internal"/"external" prices,
it seems to cost about $30 to have the external USB3
case removed and discarded.
I have found those drives to be even more reliable
than an Exatron Stringy Floppy.

Were there ever any *good* JTS PATA drives?

Bill,
I have a 30 year old IBM SCSI drive that still works great. Yes,
every company has had good drives and bad drives. I have had Quantum
drives that have lasted for decades and I have had ones that died in a year.
:)
GOD Bless and Thanks,
rich!
