Q about sata II (3gbps) and pci controller upgrade

[Lee]

hello people, my first post here, i think its appropriate....

Im will be purchasing a new HDD soon and was wondering (if anyone can help)
about the new serial ATA 2 interface... does anyone know if a PCI (regular
not PCI - X) controller/upgrade card will become available to allow for me
to use the 3Gbps interface? or will it only be available for PCI-X...

Does regular PCI limit transfer rate etc?

I've searched but cant confirm whether SATA2 is available yet or is
something for the future....

my spec (if it helps)

AMD athlonXP 2000
768mb DDR
60GB ATA133
DVD RW
CD RW
Geforce4Ti 4400
Asrock K7VT2 motherboard

Thanks in advance for any reply...

The only two SATA hard drives which can outperform your present hard drive
by a significant degree are the WD Raptors. This is because they spin at
10,000RPM, not because of the SATA150 interface. SATA II bandwidth is
overkill till all hard drives are 10K+ and areal density increases.

mmmm... @ £129 for 74 gig, is it the cash worth the additional performance?
wonder how long til 3gbps is at a resonable price....


thanks for the quick reply BTW

133 MB/sec. and that's much faster than any current HD. Get a WDC Raptor HD
and run it off a PCI card like SIIG SC-SAT212 or get two Raptors and run
RAID 0 off a SIIG SC-SATR12 and fly.

3gbps is an interface spec and NOT the speed of a HD.

A current model 7200RPM parallel ATA or SATA hard drive may sustain transfer
speeds of 66MB/sec. Two things prevent this from being increased:
1-rotational speed 2-areal or bit density of the platters. Until these two
factors can be improved upon, transfer rates will remain below 100MB/sec.
Nothing much has increased speeds in six years.

The SATA150 interface allows for 150MB/sec and the SATA II interface will
eventually allow 3GB/sec.
That's like having a 10" round hose attached to the kitchen faucet, with a
supply pressure of 15PSI.

RAID0 may be the answer under some circumstances.

Nonsense, drives get faster each year because there are more user sectors
per track each year.

Well, 3Gb/sec.

Raptor would be nice just too expensive at the moment, I've decided to go
with one of the below items, basicly I thought ATA133 meant transfer of
133mb per sec and ATA100 would mean 100mb per sec.

Nope, those are interface speeds and not drive speeds.

I'll be installing
Windows XPsp2 on the drive.... which would give me the quickest boot ? The
transfer rate is better on the Segate (internally) what's the difference
between internal/external transfer?

Internal transfer rate is the relevant HD spec.

Buy the Seagate. I've seen far too many Maxtor drives die the the past year
or so, right out of the box.
The Seagate also offers a 5 year warranty.

Windows XP will boot within 20 seconds on most modern hardware.

The above, as is obvious, is for the Seagate and was posted in the middle of
Seagate details. The above is the relevant figure for that drive regarding
throughput and not the other figures.

SATA II will NOT be on the market for at least another 6 months.

Thanks again for helping me make an informed choice everyone...
