wutang01 Posted January 11, 2008 Share Posted January 11, 2008 Hey guys. I tried searching on the forum to see if someone covered this topic before, but I didn't find any results. Anyway here goes: We all know USB2 uses 480 megabit/sec and eSATA transfers at 3 gigabit/sec. Technically speaking, 3 gigabit/sec is equivalent to 375 megabytes/sec am I right? Well, my Western Digital My Book 1 TB Home Edition (connected via eSATA) is only transferring at approx 30 megabytes/sec. It once peaked at 50 megabytes/sec but promptly dropped back down to 30. I'm wondering how we can maximise the speeds? Maximising it to 375 would be a dream come true :D Any help is appreciated! Thanks, ~ wutang01 Link to comment https://www.neowin.net/forum/topic/612742-maximising-esata-speeds/ Share on other sites More sharing options...
RAID 0 Posted January 11, 2008 Share Posted January 11, 2008 It's not really like that. You look at SATA internal drives and you'll be lucky to get 70 megs transfer off one drive. It's an external drive, so I'd say the speed is about right.

omganinja Posted January 11, 2008 Share Posted January 11, 2008 SATAII speeds arent actually possible at the moment, 3gbit/s is just the maximum possible speed the hdd can do. transfer files from 1 sataII drive to another and you'll get the same speed as with your mybook Link to comment https://www.neowin.net/forum/topic/612742-maximising-esata-speeds/#findComment-589127436 Share on other sites More sharing options...
wutang01 Posted January 11, 2008 Author Share Posted January 11, 2008 Yea ... I'm getting about 55MB/s to 59MB/s at the moment. Transferring from an internal SATA2 HDD to my My Book via eSATA.

omganinja Posted January 11, 2008 Share Posted January 11, 2008 Do it back the other way, what speeds do you get? Link to comment https://www.neowin.net/forum/topic/612742-maximising-esata-speeds/#findComment-589127445 Share on other sites More sharing options...
1Frothy Posted January 11, 2008 Share Posted January 11, 2008 I can't even get eSATA to work here, wait. Maybe I should try again with Vista SP1 Refresh.

jamend Posted January 11, 2008 Share Posted January 11, 2008 There is no performance difference between internal SATA and eSATA. eSATA just has different plugs and cables that use more shielding.

Chosen One Posted January 11, 2008 Share Posted January 11, 2008 No, as long as you chipset drivers are all uptodate that is all you can really do. Link to comment https://www.neowin.net/forum/topic/612742-maximising-esata-speeds/#findComment-589127482 Share on other sites More sharing options...

I had the same problem, and was stumped. My My Book could work through USB2, but it wouldn't appear in My Computer when connected via eSATA. Until I refreshed the page in Device Manager. Try it. It worked for me :) Link to comment https://www.neowin.net/forum/topic/612742-maximising-esata-speeds/#findComment-589127503 Share on other sites More sharing options...

If you have two RAID controllers on your MB, make sure they're both enabled in the BIOS. Sometimes the eSATA port is on a different controller than the rest Link to comment https://www.neowin.net/forum/topic/612742-maximising-esata-speeds/#findComment-589127519 Share on other sites More sharing options...

Of course that didn't work, thats like saying refresh the desktop if your CPU isnt running at full speed. Try changing the sata options IDE/AHCI/Auto, it might need to be on AHCI for it to work.

Try changing the sata options IDE/AHCI/Auto, it might need to be on AHCI for it to work. Enabled AHCI. Turned off PC. Turned on PC. Windows Vista loads fine. Turned off PC again, turned on eSATA device, Turned on PC and now the Hard Disk light on my main PC is on and the "loading Windows" screen is up, but that's all that ever happens, except for the odd eSATA device light flicker. But if I turn off the eSATA device while "loading Windows" is "stuck", then it resumes loading Windows without any problem. It's like it's having trouble recognizing the eSATA device at Windows load. Edit: Added screen shot of Device Manager. No eSATA drive found.

omganinja Posted January 11, 2008 Share Posted January 11, 2008 You may need drivers for your Sata controller to get AHCI to work correctly, find the chipset that controls it and google drivers for it.

It worked!!! (Y) Thanks omganinja After enabling AHCI I had to reinstall the Intel 'inf' chipset drivers. Now the Controller is no longer 'Generic SATA AHCI' it's now listed as 'Intel® ICH9 6 Port SATA AHCI Controller - 2922' and my external eSATA drive is working!

wutang01 Posted January 12, 2008 Author Share Posted January 12, 2008 Is it normal if transferring files from My Book (eSATA) to my SATA RAID HDDs ... is about 16MB/s?

Haha, they should be the same, either the read times on the SATA drive is bad or the write speed on the My Book is bad, try it from another drive to the My Book and see what happens.

+LogicalApex MVC Posted January 12, 2008 MVC Share Posted January 12, 2008 You won't be able to max out the theoretical limit of the eSATA interface because HDs simply can't transfer at that speed. You would need either a RAID configuration or something that can transfer all of its data from a RAM cache.

omganinja Posted January 12, 2008 Share Posted January 12, 2008 Umm HDDs can trasnfer that fast, thats the point of SATAII, its the other hardware that cant keep up.
