SATA 2 HDD

[YogurtPot]

My existing IBM 46 Gig hard drive recently took a tumble and the existing bad sectors spread further.

I've recently been looking for a new hard drive and a friend has offered a SATA 2 PCI card.

We have checked up and the card is compatible with the motherboard. I've been running an IDE UDMA 100 drive for ages and was wondering if anyone could recommend on whether the SATA 2 cards are worth while.

I've been told that a SATA 2 drive would only run at 100mbytes/sec on my board. Can anyone confirm this?

SATA storage is new to me so any tips and advice are welcome.

K7T266 Pro (MS-6380)
Athlon XP 2000 (25c idle)
512 MB Ram (PC 2100)
Nvidia FX 5500 AGP

Sata 300 came out after people stopped making Socket A motherboards (99% on that, there may be some odd ones from ASRock or someone) so you're gona be limited to 150 (SATA '1' spec).

I run two SATAII/300 drives on my Socket A system and it works just fine, although you've gotta jumper them down to 150mb/s.

It's still noticeably faster than PATA though.

* That info only applies if you're using an onboard SATA controller, which you're not. SATA2/300 will run full speed if you're using a PCI controller card.

Yes, because it's the future.

Performance wise it's only marginally faster than a fast PATA and will never see 300 or 150 tranfer speeds with current drive technology.

So will the SATA 2 card run at 150 or 300 on my board?

 

[sandmanwn]

the SATAII expansion card will run the drive as SATAII/300. no worries.

As an expansion card it uses its own controller and the PCI bus to run the hard drives and is not limited by the motherboard controller.

compared to that old IBM 46GB HD it should be a night and day difference.

Thanks a lot for the help.

The HDD won't go really faster than 60 Mbytes/sec.. HDD are not fast enough to saturate the interface bandwidth, be it ATA100, sata150 or SATAII, so don't worry

I was hoping to get a speed increase from the SATA2 upgrade. So apart from the Cache and the Rpm would I see any improvement in transfer rates?

I seem to be getting contradicting information everywhere I go.

Well perhaps not the interface will make a difference, but the newer drives have more advanced tech and so any new drive willl be faster, even if it's not from the interface.

I saw a definite speed increase from PATA to SATA-150, so even if the interface wasn't making the difference I can tell you for sure that newer drives will be faster.
