Yep, I posted that it can only support one HDD a couple of times, no matter what some sites say unfortunately. So that would be a definite no - sorry I wish it wasn't so , but at least now you know for sure .

I'm still liking my G51JX - the only thing that is bugging things up a bit is that with Battery Saving/Quiet Office mode some apps will operate extremely slowly and with bugs such as the 'flashing X' and the inability to maximize or minimize the window. That seems to still happen sometimes even with Turbo activated though - and especially with Firefox (possibly the only app I've seen do it) - so it might not be the system per se.

The one thing that has been bugging me though is the keyboard - it keeps eating up some letters consistently, and I have to often retype even though I know I typed it correctly the first time. In that last sentence the 'f' and 'c' each exhibited that behaviour, for example.

Otherwise I like the KB - the places it is a bit spongy don't seem to be affecting things too much, but somehow those keys are just not getting registered - will have to test it out more - wonder if it's just me?

Thank you. I need a couple extra drives so I'm investigating these:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817364026
Koutech IO-EEU230 2.5" Black USB 3.0 External Enclosure
http://www.newegg.com/Product/Product.aspx?Item=N82E16839104025
Koutech IO-ECU230 Dual Channel SuperSpeed USB 3.0 ExpressCard

The specs say they are supposed to support up to 1TB external drives and SSDs. I will get them this week and test performance in my old laptop. Another test is comparing USB 3.0 to eSATA on same drives.

I have heard of keyboard lag issues on some ASUS because of touchpad driver issues. Some resolved by updating drivers or disabling touchpad, but I'm unsure if this might fix anything on G51JX.

Thanks for the definitive answer. Good luck!

No problem, happy to help .

Ya, it would certainly be nice to know if there is a performance difference, but the bottleneck could be the USB3.0 hub itself (rather than the drive) or some other part of the system more so than the drive (or enclosure) - depending on how things are implemented, if there is something else going on, and so on. Just incase - I did some detailed tests awhile back only to realize belatedly that it was the computer itself that was slowing things down rather than the peripheral (there was a system maintenance app silently running and sucking up resources in the background) - but if you see a big increase over the eSata and USB3.0 performance then that's great - of course it won't be as big as it seems on paper, but if you need the speed it can be worth it certainly.

Nice to see the USB3.0 Express Cards are so cheap! Too bad it's sold out, but the fact its like that now, when I do actually get an external drive/enclosure that supports it, then it should be pretty easy to come by and not too expensive . The only thing I'd be careful about is the plastic and metal juncture - I had an old style Wifi Express Card on my G732 and over time it got worn down until after I'd given it to another family member when it finally split along the plastic and then metal seams - they almost lost one of the pieces before I taped it all together with some electrical tape. So I'd just be gentle with it and make sure nothing pushes it either way, and if it looks like it might, then (if you're not currently using it) you might want to take it out rather than leaving it in the slot - that's all really.

Also good to know 2.5" (and smaller) SSDs have such high capacities - too bad the cost is prohibitive, but if the tech is there the price will eventually go down as the demand increases and it becomes more competitive with the magnetic drives - good news .

Thanks for the suggestion about the keyboard lag issue - I remember reading about that vaguely as well. I'm noticing it a fair bit more on my N10J Net/Mini Notebook so there certainly that could be it. I often get popups telling me that the keyboard input is delayed, and I'll be sitting there 30 seconds after I finished a paragraph typing at my normal moderately brisk pace and it'll still only half on the screen.

For the G51JX though it's more like some keys are just being missed - possibly I didn't hit them hard enough - I know I touched them, but possibly not firmly enough to trigger the pressure point. So it could be just me and the keyboard not getting along I suppose - if everyone was having the same issue it could be a defect in design though. Or I could have a bum unit if it's just me and I can ask for a replacement part... - so I guess if anyone out there notices this (or not) if you can let me know that'll help answer my question .

Thanks,

PJPeter

When it comes to the external drives - don't forget that there is SATA socket in our laptops! It wil be definitely faster than any USB.... just a thought...

Great point. If this model had two HD internal, I would have already bought it. If I can not get a couple good performing HD (internals or internal and external) I will choose another model/brand.

I have seen many performance issues with SATA cables so it might be hard to extend that socket somewhere and still get great performance. Interesting idea if anyone has ideas or if ASUS has future plans.

One thing concerning the eSATA slot - it does not provide power on its own if I recall correctly, you must have external power hooked up the drive.

Is our eSata is 3Gbit/s right? The older version is 1.5Gbit/s and the newer one is 6Gbit/s. The eSata 3G was often called eSata II - but on the notebook chassis and in all the specs I can see it is just listed as 'eSata' so I'm not sure what generation it is. If it is eSata 6G then it wins over USB 3.0 of course, since USB 3.0 is only 4.8 Gbit/s - but eSata still requires an extra power adapter and isn't necessarily as plug and play friendly* as USB3.0 nor is it likely it will be nearly as widely supported.

PJPeter

* I know gen 1 eSata ports required the HDD to be plugged in before boot and not removed, but I think the G51JX supports hot swapping eSata drives so that might not apply.

I called them, and the second HD is provided in place of optical drive by these guys:
http://www.xoticpc.com/asus-g51jxa1-p-2724.html?wconfigure=yes

Basically, they mount a 2.5in drive mount (available from ASUS online) in the optical drive bay, and its fixed in place. They must route the internal connection to it. But, no optical drive in this configuration.

HTH.

-- followup info on USB 3.0

I tested the Koutech USB 3.0 ExpressCard (x2 port) and its great. There is one 5v USB 2.0 cable that plugs into the side of the express card so you get powered USB 3.0 to the drives. In this configuration, the drives only require one USB 3.0 cable. The external USB 3.0 enclosures from Koutech comes with a 1ft cable which is very convenient. There is a second USB 2.0 Y-cable on the 1ft cable that provides power (optional) if you use the enclosure on a non-powered USB 3.0 port. My SSD also works great in this configuration, giving over 100MB/s and it is an older SSD without command queuing.

The USB 3.0 stuff is slightly faster (2MB/s) than my eSATA ExpressCard and enclosures on the same port and drives.

Hello peter.. Im just new here.. Ei peter i just have one single question... why does the video card downclocks when the battery is not plugged in? i have the gts 360m very sad why this thing is happening.. is this normal? it only remains normal when the battery is plugged in...

Hey nemo, You can set it not to downclock if you like - just download the Overclocking App mentioned earlier in the thread and manually set the clocks that way. You can also change some registry keys to disable that downclocking as well. You're sure though is the downclocking and not the 'Battery Saving Desktop' though right? That is also enabled by default. I think all those details are posted earlier in the thread - but if you cannot find them let me know and I'll help you more specifically .

Glad to hear the SSDs are working well mhthomas . I was considering getting one of those optical drive replacements when you mentioned it, checking it out it looks quite interesting - but I would like to get a Blu-Ray Burner eventually and so I'd like to keep that bay there. True I can use an external one for either, but I think there will be more cases where I'll wish I had the ODD but forgot it than that I had that second HDD - so I'll stick with that way. Thanks for pointing that out though .

I wonder though, getting an SSD that would fit into the express card slot, that wouldn't take any more space outside and would only really prevent me from using a USB3.0 express card - since I don't have any other plans for that slot. It'd be nice to have that second HDD/SSD slot if only so I can use even a small SSD to make booting and OS operations faster.

Hmm, it's got me thinking - thanks ,

PJPeter

ei peter..  can't find those.. ^_^ can you help me?

and peter... i just wanna ask what kind of application you used to overclock yours? cause my evga precision always reset at stock settings whenever i restart my comp.. i want to make the overclock settings my stock settings and by default.. so i dont need to overclock again and again.. tnx peter..

btw... i try to install the nvidia essential tools with esa support from the nvidia site but it my G60JX always crashes when it installs... guess i'm too unlucky...

Hey nemo,

Sorry about the slow response. I can't say 100% if the overclocks stick, since I haven't wanted them to - but they should. The app is this:  Nvidia System Tools 6.05.

For info on the PowerMizer Registry Edit see page 5 of this thread, my post near the bottom has full details .

Thanks for the reply peter... but peter. my asus G60JX doesnt have the powermizer.. it has Power4Gear Hybrid.. Do you know anything about this thing? BTW.. i found out a new driver for the gts 360m it is the 257.15 beta released from nvidia.. check it out.. my gpu never runs above 80 degrees even after 3 hours of gaming...

Glad to hear it Nemo - I'll have to give it a try .

The G60JX/G51JX, etc... all use PowerMizer - but its a hidden feature of the nVidia software/registry settings - it downclocks the GPU when not being fully utilized (though it isn't perfect of course, and can cause slowdowns depending on the settings). P4G is more specialized towards controlling the CPU (in addition to brightness, timers and a few misc things).

Hope that makes sense,

PJPeter

thanks for the info... after all i found out that i really need this powermizer feature for my gpu not to run very hot..

one more question.. is the gpu downclocking when i am not playing games? i mean will it cooldown after i play bad company for 3 hours?

Hey nemo,

Yes it should be downclocking - you can download various apps or even just the nVidia Control Panel to check what the clocks are and even force it to if you want to to make sure it does .
