L.C. Posted July 19, 2007 Report Posted July 19, 2007 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.
PoLiX Posted July 19, 2007 Report Posted July 19, 2007 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. Posted July 20, 2007 Author Report Posted July 20, 2007 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 rateCould someone really explain this to me? I was really hoping for a major boost in DTR performance.
L.C. Posted July 20, 2007 Author Report Posted July 20, 2007 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 Posted July 20, 2007 Report Posted July 20, 2007 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.
L.C. Posted July 20, 2007 Author Report Posted July 20, 2007 -- 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?
Yavaris Posted July 20, 2007 Report Posted July 20, 2007 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. Posted July 20, 2007 Author Report Posted July 20, 2007 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.
