Since Hitachi took over IBM's Hard Drives, are they better or much the
same.

TIA

Performance is best for 7200rpm HDD.
However beware of a loud whining noise every now and then.

Still great disks. (not counting a certain production batch of 75GXP
IBM disks of course :-))

At the moment the 7K250 is easily the fastest 7200 rpm disk that you
can buy. It also very quiet. (Quite a large difference to my DiamonMax
Plus9 disks)

What kind of sound does it make when moving the heads to prevent heat
buildup? Anything like the 1-2 second sound every 10 minutes for the
180GXP?

In 10 minutes the heads will have lighted up themselfs and that
particular platter area if staying in the same place for that long.

Don't know. I haven't heard that sound on my disk yet. (Installed it
about two weeks ago)

You would have been very much aware of it the first day if the 7K250 was
making the same sound as the 180GXP. Like I said, for the 180GXP it's a
(very audible) 1 or 2 second sound every 10 minutes.

This is good to know. Maybe IBM/Hitachi drives are worth buying again.

I know that 180GXP sound. (I also owned one of those)
It's a good thing I knew the 180GXP makes strange noise before I
bought one, or I would have been very worried when I first heard it
:-)

But my 7K250 hasn't make any noise like that. Maybe it still moves the
heads to prevent heat buildup, but if so, it does it without making
noise now.

The 7K250 is certainly my first choice at the moment.

Of course it does. And they always have been.

I don't get the point of your two posts. Are you saying the 180GXP
sounds isn't to prevent heat build-up? If not, what's the drive doing
for that 1-2 seconds, and why don't other drives need to do it?

He's deliberately cryptic quite a bit of the time.

Its one way of trolling.

You took the bait.
Are you saying the 180GXP sounds isn't to prevent heat build-up?

No, he's saying that specific steps have been taken to
prevent the heads sitting on the one cylinder for long
times, so you dont get local heating, for years now.

He's just saying that while the 180GXP is audible when
it moves the heads around to prevent that, the 7K250 isnt.
If not, what's the drive doing for that 1-2 seconds,

Preventing local heat buildup when
the heads arent doing anything.
and why don't other drives need to do it?

They do. They just dont make that stupid
noise when doing that that the 180GXP does.

The fool that 'designed' the 180GXP to do it so
noisily that the user wonders if its normal should
have been taken out the back and shot.

Maybe he has and thats why the 7K250 does it quietly.

It would be the firmware that's doing it. An upgrade should be able to
'fix' the problem...someday.

The 7K250 is only 2.6 bels for one disk (but I'm so confused - the specs
don't say if that's power or pressure :)) compared to your Samsung's 2.7
bels. It's faster too. Might not be a bad drive to buy.

I've decided I don't want to buy another ATA drive. Maybe by spring
time I've be able to buy a BTX case and MB and all SATA drives,
including a writable SATA DVD/CD drive (strange there aren't any SATA
optical drives on the market yet).

Duh.

They mostly dont bother with that sort of thing.

And even you should have been able to grasp that
that sort of measurement doesnt even register
those sorts of irritating but relatively rare noises.
It's faster too.

Bet you'd never be able to pick it in a proper double
blind trial without being allowed to use a benchmark.

You'd certainly be able to pick that terminal
stupidity with the deliberate head activity tho.
Might not be a bad drive to buy.

Dont care for Hitachi's warranty policys myself.

And when they've never had the balls to fess up to
what the problem was with the infamous GXP drives,
they can take their drives and shove them where
the sun dont shine as far as I am concerned.

I'll buy drives manufacturered by operations with a clue myself.
I've decided I don't want to buy another ATA drive.

The main problem currently is that there are few
native SATA drives buyable. Most are bridged drives.
Maybe by spring time I've be able to buy a BTX case and MB
and all SATA drives, including a writable SATA DVD/CD drive
(strange there aren't any SATA optical drives on the market yet).

Nothing strange about that.

Nothing strange about it--most of the SATA host adapters currently on
the market don't support ATAPI devices, nor do most of the bridge chips,
and the ones that do are only guaranteed to work with the same brand
host adapter chip. There's no real benefit to SATA for opticals
anyway--their bandwidth doesn't come close to filling a parallel ATA
pipe and the drives don't generally get hot-swapped so the only gain
would be the longer cable.

True.
I got that 7K250 drive as a replacement for a 60GXP that broke down.
In the benchmarks the 7K250 is a lot faster, but I can't say I really
notice the difference between those drives.

BTW I got a 60GB version of the 7K250. But officially there is no 60GB
version of this drive.
(guess they don't want people to destroy their 60GB disks so that they
get a bigger and faster drive in return :-))

stupidity with the deliberate head activity tho.

No doubt about that :-)

What's wrong with it?
Seems just as good or better than the competition.

IBM hasn't been the only company which has had a bad model once.
(Problem with the 75GXP is that it also happened to be an extremely
popular model)

native SATA drives buyable. Most are bridged drives.

Why would you care if a drive is native SATA?

I see bridged drives which are faster in every way then native drives.
So I couldn't care less about native SATA drives.
The actual performance is what I find interesting. Not how it is
designed internally.
Nothing strange about that.

Why not?
The advantages for SATA optical drives are the same as for harddisks.
I think there would be a market for it by now?

Philips demoed one over a year ago saying "We are very proud to be at
the leading edge of the Serial ATA transition, and helping demonstrate
the interface’s outstanding functionality, reliability and performance
with our latest DVD+RW drive." So much for leading edge - we're still
waiting for a Philips SATA DVD drive.
There's no real benefit to SATA for opticals
anyway--their bandwidth doesn't come close to filling a parallel ATA
pipe and the drives don't generally get hot-swapped so the only gain
would be the longer cable.

SATA is the *replacement* for ATA. That's reason enough. Mice and
keyboards don't need the bandwidth of USB either.

And Phillips is probably waiting for everybody to start using the host
adapter chip that is compatible with the bridge chip they used in their
demo.

When it replaces ATA then it will be the replacement for ATA. That's
not going to happen until somebody starts producing southbridge chips
with built in SATA and no PATA. And I suspect that that won't happen
until there is serial ATAPI standard agreed upon.

Yes.

If not, what's the drive doing for that 1-2 seconds,

No one seems to know exactly but the most probable
is running S.M.A.R.T. tests for internal logging.
and why don't other drives need to do it?

That depends on what you call "need".

Yeah, that sort of deliberate short stroking has been
around for quite a while now from some manufacturers.

While I can see that thats likely why they do it, to
stop people deliberately killing their drives to get a
bigger replacement, I think it would be a better policy
to not short stroke the drive as a sort of bonus for
those who have been ****ed around by a drive failure.
No doubt about that :-)
What's wrong with it?

They dont cross ship the replacement.

Thats much more convenient for the user who
isnt then without a drive for any time at all, and
if the drive isnt completely dead they may be
able to copy stuff from the original drive too.

And can use the shipping container the replacement
showed up in to send the failed drive back in.
Seems just as good or better than the competition.

Fraid not. They can be surprisingly
slow to send out the replacement too.
That was IBM :-)

Its only the OWNERSHIP that changed. The same monkeys
are largely involved in the design and manufacture of the drives.
IBM hasn't been the only company which has had a bad model once.

Sure, but thats not the problem. The problem was that IBM
kept denying that there ever was a problem with those drives.

Let alone actually fessing up to what the problem actually was.

I find it VERY hard to believe that IBM never did manage to work
out what the problem was, and if they didnt, I wont be touching
any of the drives made by an operation that incompetant.
(Problem with the 75GXP is that it also
happened to be an extremely popular model)

The problem was that IBM never did admit
that there was any problem with that model.

And kept shipping the suckers another 75GXP
when the first one was RMAed, which went on
to fail itself quite a bit of the time. Utterly obscene.
Why would you care if a drive is native SATA?

Basically just a cleaner design. And thats got to be visible
in the price once the volume gets up to pata shipping levels.
I see bridged drives which are faster
in every way then native drives.

Bullshit. Drives are still doing what the physics allows.
The interface is irrelevant on speed with current drives.
So I couldn't care less about native SATA drives.
The actual performance is what I find interesting.

You dont get any better performance with mechanically
identical drives which only differ in the interface used.

One advantage with sata drives is the cleaner cabling.

One risk currently is that the technology isnt as mature.
Not how it is designed internally.

Thats what matters performance wise with hard drives.
Particuarly the basics physics of rpm, platter sizes,
numbers of platters etc for a particular capacity.

Optical drives dont even get within a bulls roar
of exploiting what the pata interface can do.

The only real advantage is a cleaner cabling system.
That can be handy with bigger cases and optical drives.

And the main downside is that there are few motherboards
with that many sata ports currently, not enough to be
able to handle the 4 drives of any type many want to have.
The advantages for SATA optical
drives are the same as for harddisks.

Nope, they dont get anywhere near wringing out the pata interfaces now.
I think there would be a market for it by now?

Nope, because there arent many motherboard with JUST sata ports.
