For SCSI Seagate, Hitachi, Fujitsu & Maxtor.

Most definitely avoid Maxtor and Hitachi - although I don't have much
experience of Maxtor's enterprise drives, so I can't comment.
Nearly all my data recovery work comes in the form of Maxtor, Hitachi,
Western Digital, the old Quantum drives, and a mixture of others -
pretty much in that order.
Six months ago, the positions of the first two in the list were
reversed.

In terms of reliability - it's the one you purchased 10 years ago that's
still running.
In terms of cost - it's the one you buy next year.

Ignore this Seagate shill.

There is no such animal.
The cost can vary a lot with rebates etc, and its impossible to
get a real handle on reliability. No one except the manufacturer
sees enough drives to be able to say much about reliability.

This is the clown that is so stupid it never even noticed
the problem with the IBM 75GXP, even when it was
so unreliable it produced a full class action suit.
He clearly wouldnt have a clue about hard drive reliability.

Doesnt prove much if those that buy particular brands do full
backup more often and so never need to use you when the drive dies.
Its likely that those buying the cheapest drives do the least backup.
The technical term for that is 'pathetically inadequate sample'

In spades with the length of time most keep a drive for |-)

Manufacturers usually publish MTBF or AFR (at certain POH) rate
as a measure of reliability.

Yes, but thats useless as a measure of reliability.
Fraid not. Most obviously with the IBM 75GXP and Fujitsu
MPGs which did turn out to be much less reliable than other
manufacturer's similar drives with identical MTBFs and AFRs.

I think you confuse reliability with dishonest marketing practices
of some companies. It is possible that product manufactured at
later date has lower reliability than originally claimed. It is up to
the manufacturer to disclose that information and recall faulty
product, reimburse unfortunate clients or keep quiet.
Manufacturer has an obligation to check product quality on a
regular basis, to make sure it has required properties.
It is like saying that stress analysis is useless because it has
been an accident where a modern bridge collapsed.

'think' again. I made no comment what so ever about marketing
practices and JUST commented on whether there is any correlation
between MTBFs and AFRs and real experienced poor reliability
of a couple of models compared with their competitor's products
which had the SAME MTBFs and AFRs and MUCH worse reliability.
And the reality is that MTBFs and AFRs have NOTHING
to do with actual failure rates actually achieved.
Separate issue entirely.
What they actually do is observer the field failure rate.
Nope, nothing like. MTBFs and AFRs with hard
drives arent something that is actually measured.
That should be obvious from the FACT that MTBFs and AFRs
dont change over time as the manufacturer observes the field
failure rate actually seen with that particular model.

Seagate currently offers 5 year warranties for almost all their drives
(1 year for external USB). Most other manufacturers have shorter
warranties (1-3 years). Since a longer warranty without corresponding
product longevity is likely to cost Seagate serious money, I am inclined
to think they have high confidence in their product. This is good
enough reason for me to buy Seagate exclusively right now. The cost
differential is minor between brands so I opt for Seagate.
Incidentally, I do not believe they are immune to failure & back up
religiously - In most cases returning a drive under warranty would be
small consolation relative to data loss especially with todays very
large drives.

Nope, the fact is that most current HD models will last 5 years. Each year
a drive is in the field does cost the mfg some money and each year is not a
lot more expensive than the previous year until the drive life knee in the
curve is reached. Seagate began the 5 year warranty suddenly by
proclamation and it covered drives already mfged and in distribution. Those
ATA model had 1 or 3 years warranty at the time but all had a design life of
5 years as do most all HDs models from all mfgs then and today. Warranty
length is a marketing and price point decision and has little to do with
reliability.
The WDC SATA Raptor has a 5 year warranty.
Do you derive income from Seagate or selling its products?

Thanks for your replies.
What is the cheapest (in terms of 1 mb) way to back up?

That is exactly the perception that the Seagate marketing department wants
you to have.
Simple fact--failing in less than five years is unusual for disks of any
brand.

Thanks for your reply.
If I ASSUMEd that my drive was going to fail tomorrow I would use
mirror drives because I want to retain files which I created today.
