What's the scoop on these? They cost a bit more than regular WD
drives, but have the fluid bearings and claims of higher reliability.

That is a lie, maybe higher than the worst of the WD drives tho.

I'd like to know why MTBF ratings keep going up, now over a million
hours for some drives, but the expected lifespan remains at five years
(and that may be for only eight hours of use per day).
Because if drives really are better now, shouldn't their
expected lifespans also be higher?
I thought that all new WD drives now use fluid bearings.
I know that the 120GB one I bought this Labor Day does.

of 4) fail. The failed drives lasted about 12-18 months. The survivor is
just under three years old. They weren't overheated - Two were used in a PC
fitted with tripple drive fans and one in a big all metal fan equipped 5.25"
external enclosure that was never transported/moved. All three made strange
mechanical noises - typically at startup - anything from a quiet ticking to
a screech. I've decided to replace the latest failure with a Samsung
Spinpoint drive. I've no idea if they are any better - will let you know how
they do in three years time.
Iago said:I don't remember a claim of high reliability, but that can be just
semantics. Those drives should work better with a RAID controller.
That is why you should have a reliable backup. Any brand hard disk
can fail. Any time. With reliable backup it is just a nuisance to
restore systems after replacing failed hard disks. You have a bit
less of that hassle if your disks are better quality, thats all. You
pay for it.

That's really just the cost of the longer warranty.
They all do now.

1 / <MTBF> = <propapility of failure per hour of operation>

to pay anything for that.
Odd. They do say that their cheap "mainstream" line uses the fluid bearings

But there's no mention of it on the "high performance" EIDE line

They don't explain what would make them more reliable, however...
Actually they do, one click deeper:

electrolyte capacitors that do not live too long but are far cheaper
than, e.g., long-loved ceramics. Semicondictors run cold (e.g. 40C)
have something like 30 years lifetime. It halves every 10C or so,
regardless of whether the device is operating or not.
