Finally, we'll be able to buy cheap 10000rpm hard disk drives.

because I imagine a 20k rpm disk using a lot

Depends mainly on the amount of friction, or air resistance in particular. Resistance to air does not scale linearly with speed, otherwise power consumption would scale reasonably linear.

forget 20000rpm

i want a raptor its rpm creates wormhole to travel through space/time.. the internet is boring.. i want to surf the universe/s.. and a on the fly blackhole for absolute data destruction

lol

hopefully enough black/anti-matter prevents data corruption

Lol as Dino say u could shake sth, instead of shaking sth u just put on top of cabinet...

screw having super sonic velocity HD's light speed ones- the information is there before you even start downloading it.

O Rly?

I'm skeptical. VERY skeptical.
20k? When even hi-end server drives are 15k?
Server drives turned to higher speeds faster, so I don't believe that
trend would reverse here - server business is more lucrative, I'm
sure they don't want them to buy sata drives instead of sas & scsi.
The next logical step would be raptors catching up to 15k speeds,
not the 20k jump at once.

correct me if I'm wrong, but WD dont have real server drives, so they dont have anything to lose unlike Seagate/Hitachi

Naah, next year maybe, but this year SSD that aren't more expensive than the rest of your system can't even store Vista itself, much less let you install anything on them.
OTOH, you can't put the VR in a laptop, you can put an SSD.

First thing that popped into my head, the server market has them :shrug: I'd think they would milk us at 15K then move onto 20K to milk us some more :ROTF:

Yes, but if 20k drives were feasible, the server market - where they can pay
hefty sums for faster drives - would already have it. I find it hugely unlikely
that they will manage the jump to 20k and keep it competitive in price.

Unless the 20k drives cant be made to a proper stability/longevity tolerance that is needed for servers. Also may be a very small size, servers using SAS arrays usually use a minimum of 150gb drives.

What this seems more like is trying to attack faster access speed a different way then what servers do. Servers have fast (usually 15k) SAS or Fibre Channel Hard drive raid arrays allowing for large files to be sent and stored very fast, decent servers dont use slow SATA.

This 20k raptor drive is trying to work within the confines of the SATA interface and still increase speeds, so their doing it the only real way they can, by increasing seek time to make up for the slower transfer speed.

HDs should just be for large storage.

I can think of much better ways to sepnd several hundred dollars... Until the technology matures, this will be a good stepping stone.

I was thinking of posting something similar.

Even if manufacturable a 20K RPM drive will be pathetically lacking by the time it's brough to market.

This reports sounds very FU(A)D like to me.

With SSD don't you just love "Moore's Law" . The performance of a computer dervice will double every 18months! So give it 3 years and SSD HD will be in your average Dell/HP!

YEAH RIGHT.. 20K RPM for SATA drives? My arse.

I think WD really means 20K for SAS drives, not SATA. They want to conquer the SAS market, seeing how they enjoyed huge success and popularity with the Raptor drives in the SATA/IDE market. It's a business model, dude--the board of directors are eyeing all of that potential out there.

Suppose that WD is indeed gonna sell a 20K rpm drive, but you think it will be a SATA drive. Then I'd love to make a bet with you that it's a SAS drive. You decide the betting wager!

Its like a Camara company refusing to admit that film is dead.

Yes, it will.

Why do people keep thinking that the SATA II bus won't be sufficient for some time to come (or also that the current SATA I spec isn't good enough for traditional non-raptor/non-ssd drives)?

SATA II runs at 3.0Gb/s, or 375MB/s. Even if this 20krpm drive TRIPPLED current drive speeds, it still couldn't saturate the SATA II bus.

Yeah, I'm quoting you two for the same thing as above. 375MB/s possible on SATA II... even with the fanciful *projections* of SSD manufacturers (and really, we all know we have to reduce the numbers they say they may hit in a year or two, right?) we still won't saturate it until well into 2010.

I agree with shintai. HDD is soon to be for high volume capacity storage, that is all. SSD all the way for OS drive..

i plan to ditch my raptor 150 and replace it with a ssd next year if they are under 250 or so. Raptor 150 has been fine for me as my main drive, plenty fast..

20,000 rpm will be hot no matter what they do, and power draw will be higher..WD needs to get with the program

hehe the ssd wars.

i wonder what more do hhd makers have under their sleeves :D
yet they can't do nothing ! against the overtaking of ssd as an os drive.
to reach high volumes so it will be able to be also a data hd we still need few years for sdd to be as cheap as a hhd
and that will definitely happen, till then the hdd will remain.

but all of those hdd manufactures see that and start to get panic,
wd like seagate will be the first to get hurt. so they start shooting in all directions,
the 20k hdd i guess is one of them. hybrid hdd is another,
small size high volume hdd is also one that i can think of but .... there are not many others.
only if we have 1TB 20k raptor it'll satisfy me, a 300 gb 2kk hdd is no match for a 300 gb ssd.

hdd technology is one of the oldest there is and a new kid came to town :)
those hdd giants need to get of their lazy butt which got abit large in the last decade.

Film is, actually, still much better quality than digital, albeit not as convenient.

They could make it work on both, it's already an all-out drive, might as well provide backwards compatibility to SATA.
