[Irrelevant] 500GB SATA-II (300Gb/s) Harddrive

[L.C.]

Why is my SATA harddrive transfering at speeds from 64MB/s to 70MB/s rather than from 150MB/s to 300MB/s? Properly installed and connected to my motherboard with a 300Gb/s cable.

you mean 3gb/s not 300gb/s.

 

Does your motherboard support 1.5gb/s Sata or 3gb/s Sata II?

 

if the 1st, you need to jumper it to make it run properly at 1.5gb/s.

if the 2nd, than what are you transfering from and to? Could also be causing the issues.

[L.C.]

I know that my motherboard atleast supports 1.5Gb/s SATA. Harddrive has jumpers, but I got it OEM with Warranty from NewEgg.

 

Motherboard: ePox 8RDA3+ Pro

Harddrive: 500GB Seagate Barracuda 7200.1 SATA 3Gb/s

 

If my motherboard suports 3Gb/s SATA-II, then I'll pretty much say everything. Very much like a regular IDE harddrive. Fraps is one of them. I measure speeds with Diskeeper and Nero.

 

 

 

After looking at the links...

+SATA 3Gb/s interface

+78 MB/s maximum sustained data transfer rate

Could someone really explain this to me? I was really hoping for a major boost in DTR performance.

According to the manual I have to remove the pin-connecter to enable 3Gb/s SATA-II. So I'll do that for the sake of maximizing performance, whether it does anything significant or not. Could someone still explain to me the "78MB/s" and "3Gb/s" confusion I am having?

[🜲 PoLiX]

that mobo is too old to support sata 3Gb/s (300MB/s). Leave the Pin in, or you'll get all sorts of errors.

 

1.5Gigabits/second = 150Megabytes/second

 

78Megabytes/second = the maximum sustained, or constant transfer. If I remember right, the 150MB/s = the speed data is passed between the memory and hard drive, and 78MB/s = the transfer from 1 hard drive to another, or cd-rom to hard drive.

SATA-SATA-SATA would offer best performance for Fraps recording, in this example...then? At the moment I can only do IDE-SATA-SATA. Sometime I gotta reinstall XP onto my SATA. My copy of Windows XP is installed on an old 40GB Maxtor with a DTR of 32MB/s. My newer 200GB Maxtor has a 64MB/s transfer, whilst my 500GB Seagate (SATA) has a 70MB/s transfer. Worth going all SATA?

1.5Gb/s = 187.5MB/s = the maximum speed a SATA1 connection can handle.

0.7Gb/s = 70-80MB/s = the maximum reading/writing speed of todays SATA harddrives.

 

SATA2 is 3.0Gb/s. See how the max speed of drives is way lower than that. So it's basically all just a selling trick. SATA1 will do fine. Only if you put a SATA splitter in one of your SATA ports on your motherboard it would of any use, since then 2 or more drives will have to share 1 SATA connection.

 

That old Maxtor of your might even have a slower RPM (5400 or something if its pretty old) so upgrading it to a new drive will translate to faster loading and faster booting.

 

A couple of months ago I upgraded from a 7200rpm pata drive to a 10000rpm sata raptor. Before I could go to the toilet and still my PC would be booting up after I'd come back. Now I can't even blink (mildly exaggerated). So its seriously worth considering.

[L.C.]

Eh, my Maxtor is 7200RPM, but this baby is just getting old. I've had it atleast since 2000 and bought it at Fry's for a ripoff $120 with new cables.

 

Hey, thanks for the information about SATA/IDE/RPM. :] I learned something.
