RE: Good news / bad news - The joys of RAID

I have had far more failures of Maxtor drives than any other.  I have also
had problems with WD drives.  I know someone that had 4-6 IBM disks, most of
which have failed.


I am talking about disks with 3 year warranties!  Based on the spec.  But
OEM disks have none.  You must return them to the PC manufacture.
Most of my failures were within 3 years, but beyond the warranty period of
the system.  So the OEM issue has occurred too often.

I have had good luck with Seagate.

I use RAID, it is a must with the failure rate!
I do backup also, but RAID tends to save me.

Most people have a PC with 1 disk.  I don't understand RAID, and they don't
understand that everything will be lost if the disk breaks!  They think
"Dell will just fix it".  But wrong, Dell will just replace it!  Big
difference.

Today's disks claim a MTBF of about 1,000,000 hours!  That's about 114
years.  So, if I had 10 disks I should expect 1 failure every 11.4 years.
That would be so cool!  But not in the real world.

Can you explain how the disks have a MTBF of 1,000,000 hours?  But fail more
often than that?  Maybe I just don't understand some aspect of MTBF.

> Never buy Maxtor drives again!

you imply that Maxtor drives are somehow inherently flawed.
can you explain why you think millions of people/companies
are naive idiots for continuing to buy Maxtor disks?

this sort of thing is just not plausible: Maxtor competes 
with the other top-tier disk vendors with similar products 
and prices and reliability.  yes, if you buy a 1-year disk,
you can expect it to have been less carefully tested, possibly
be of lower-end design and reliability, and to have been handle
more poorly by the supply chain.  thankfully, you don't have 
to buy 1-year disks any more.

read the specs.  make sure your supply chain knows how to 
handle disks.  make sure your disks are mounted correctly,
both mechanically and with enough airflow.  use raid and 
some form of archiving/backups.  don't get hung up on which 
of the 4-5 top-tier vendors makes your disk.
