Slow eSata transfer rate

[jslegers]

Hello,

I'm using a Asus P6T SE mainboard. I have connected an eSata (onboard jmicron controller) harddisk (Akasa enclosure with an Seagate 7200.11 750 Gb HD). Sometimes when I copy files to or from the local harddisk the transfer rate is slow. About 13 mb/s but sometimes it is also fast 90 mb/s. I'm using the latest drivers from jmicron. What could be the problem of the speed differences ?

I try to transfer files and it slows to 13 meg a sec and then just stops and goes idle until I reboot. I think this issue is widespread but I don't believe anyone has yet found a relation as to why for some and not others. I have 6 WD 500gb external so that = 6 usless external drives..

If you have AHCI enabled in the bios W7 installs a driver but you also need the Intel Matrix Storage Manager for correct functionality :

You will find it at the intel site - http://downloadcenter.intel.com/default.aspx
Select chipsets - chipset software - intel(R) matrix storage manager - Select Operating System - select Windows 7 (64bit OR 32 bit) - select drivers - select intel(R) matrix storage manager 8.9.0.1023 - download and install.
(make sure you don't download the floppy configuration utility by mistake) - it will show up if you select utilities.
