 Actually, you don't get a new drive.  You get someone else's broken
 drive that's been factory refurbished.  At least from every
 manufacturer I've ever dealt with.



   
So, the insurance companies should give you a refurbished life back?  ;-)

Hi,

While it is always a good thing to have a longer warranty, I wonder what
the perception of warranty is.
Ex. I had drives fail well within the warranty timeframe. And it just
means that you get your drive replaced or your money back. IMHO it does
not necessarily mean that the drive will be more reliable.

Well that's about as cynical a viewpoint as I can imagine.

They are warranting to me that I will have the use of their drive for
5 years for the same money that their competition will only warrant
for 2 or 3 years.

I fully agree that the money/year ratio is far better with longer
warranty coverage.

However my point was that the disks  will not always be more reliable.
At least this is my experience, no cynicism intended.

Warranties give the manufacturer an incentive to make drives that will
outlast the warranty period.  Handling replacements or refunds costs far
more than any profit they might have made.  Warranties are not a
guarantee that no drive will fail in that time.  Only that they'll be
replaced, repaired or refunded.  So, longer warranties simply mean that
most drives will last to the end of the longer warranty period.

 of course not. Having a life insurance don't mean you will live longer...

 this is better only if the street price is the same and if you can be
 sure your dealer will still be here then (I have a lifetime waranty
 ram on my desk nobody want to take back)

Although you can purchase insurance type warranties, you can't really
compare life insurance with a product warranty.  We all know that most
of us will die eventually and insurance only helps with the financial
details, supporting family etc.  A warranty offered by the manufacturer
states that they believe the device has some expected lifetime and with
replace it if it fails sooner.  They have a financial incentive to
ensure too many devices don't fail prematurely, as replacements cost
more than they earned on the sale.  If they cut back on quality, they
can expect the warranty costs to climb.  The only thing comparable in
life insurance, would be premium adjustments, based on life style i.e.
non-smokers etc.

most HDrive will die :-(, the only question is when? same for us. for 
any manufacturer any _long_ term waranty is a bet on the future. They 
bet the additional benefit from additional sells will take over the 
drawback of disk failure.


disk makers are few and we can hope they can survive more than 5 years 
(the maker, not the drive :-), but it's only a bet.


you may be quite sure the _dealer_ you buy the drive from will not be 
alive in 5 years, hope the maker will...


see your insurance dealer, you _can_ take a life insurance _for your 
drive_, may be it will be cheaper than the extra cost from the 
manufacturer


In fact I barely understand why all these usb cheap drives are not 
raid 1, because nobody care is the drive, but cares on the data :-)
