do 5400 rpm data disks exist?

[Storm]

I like large HDD for lots of movies and mp3 and such........

so i was thinking, are there any 5400 disks around just for storage? these disks wouldnt need the high speeds that "regular" disks need, and running at 5400 rpm would greatly increase the amount of disk space.......

does anyone know of these disks being made now?

I don't see how a slower speed would "greatly increase the amount of disk space".

5400 RPM drives would be very hard to find unless you want a used one.

well as i understood, HDD disk space is the result of a number of factors, including which is disk speed...... the faster a disk runs, the less disk space available due to the fact that more physical space is required to store the data without errors....... which is why eg a raptor has so little space available.......

so i kinda want a reverse raptor........ slower, but more diskspace (not an old 5400 rpm disk)

was just wonderin if anyone knew of a manufacturer that sees this as a viable product.......

I don't think you've got it right.
It's a moot point anyway as no one makes 5400 RPM HDDs these days unless you want to use a laptop drive and then you run into space limitations.

Large, fast desktop drives are readily available...what's wrong with them?

Raptors are relatively small because they started life as SCSI drives, which are normally used on situations where high reliability and very high transfer speeds are required, but not necessarily high data volumes. De facto standards determine the size of SCSI drives.

Advances in technology have resulted in increased speed and increased data densities for desktop drives. Reducing the speed would not increase the data density any further.

I have a 150gb raptor, so the "slower speed/larger disc size" theory is not right. :) Just get a regular new HDD with a lot of space, like the new 500gb drives.

Those "new 500gb drives" are more expensive per GB.

You're better off with something like this:

Or even 2.


Just be sure that your system supports SATA first.

Aha....... then i think its time for me to shut up :P

well id like something bigger than 500 GiB....... i mean like 2x that...... (w/o raid, or using 2 drives)

ow well, i guess ill have to wait another year or 2 (but by that time ill prolly want 5 TiB disks) :)

You can already get 750GB Seagate drives and they're promising TB drives by year's end.

750GB Seagate.

Title says "Seagate Barracuda 7200.10 ST3750640AS 750GB 7200 RPM 16MB Cache SATA 3.0Gb/s (The First Perpendicular Recording) Hard Drive - OEM"
What does the highlighted bit mean?

[clocker]

The data bits stand up rather than lay flat.

Or something like that.
It's the way Seagate increased the data density on the disc.

Greatest thing since sliced bread I hear.

[lynx]

With longitudinal (standard) recording each bit has a north pole followed by a south pole, or a south pole followed by a north pole, depending on whether the bit is a zero or a one.

With perpendicular recording the north pole is on the surface and the south pole is on the lower layer (or the other way round) allowing for much greater densities.
