Question about Western Digital Computers & Internet

ESATA confusion. My system: XP Professional, Service Pack 3 AMD Athlon 64X2 Dual Core Processor 5600+ 2.81 GHz, 2GB RAM asus m2n-sli deluxe Simple question: Just got a WD 2T external, connected to the eSATA port, computer recognizes it, can transfer files. BUT--it seems to be running at USB 2.0 speeds -- took about 3 1/2 minutes to copy 4.5 GB. Hate to complain, but I thought eSATA was much faster. This is the first time I've used the eSATA connection on this computer: am I missing something obvious? Do I need to update the eSATA driver? I don't see anything about eSATA in Device Manager. Feeling (and probably sounding) stupid. Please advise.

There are not enough 'real world' benchmark reviews on the internet. The theoretical max of eSATA may be 3.0Gbits/sec (~375MBytes/sec) while USB 2.0 has 480MBits/sec (~60MBytes/sec) but you will never see this. You will be bottlenecked by the speed of your physical drive, bus speed, and other miscellaneous things that effect the speed of file transfer. I bought a drive with a USB 2.0 port, a Firewire 800 port, and an eSATA port in search of blazing fast file transfer. I found my USB 2.0 to cap out around 40MB/s, the Firewire ~70MB/s, and, to my surprise, eSATA at ~70MB/s also(!) I had my friend come over, who has a wicked awesome machine and a solid state drive, and we tested his. He had around 40MB/s on the USB 2.0, ~85MB/s on FW800, and ~90MB/s on eSATA. We concluded that we were seeing our computers cap out before the capabilities of the connections were achieved. We also decided that one of the large contributors to the issue was the spindle speed of the ext drive which we assume to be 5400rpm. Slow disk-spin equals slower file transfers. It would be interesting to test the connections from a solid state ext hard drive to my friend's solid state drive to see where the cap occurs when the spinning disk it taken out of the equation, but that is for another day.
You are not seeing incredibly fast speeds on eSATA because your computer can not handle speeds much faster than USB 2.0. Don't feel bad, my friend's $5000 macbook pro could not handle speeds much faster tan that, either. It is just how technology is, and how advertisers try to take your money. Next time a salesman comes up to you in best buy trying to trick you into buying an eSATA because it can hit a theoretical max of 3.0Gbs, punch him in the face, remind him that's gigaBITS per second, and push over a stack of books because our computers can't do that yet.
You are not stupid, my friend. I wondered the same thing when i first hooked up the eSATA. I went insane wanting the fastest file transfers because I was sick and tired of transferring slowly, but I feel better now knowing the max. Now i stick to less expensive firewire 800 because I wouldn't see the benefit of eSATA anyways (and I am also on a new macbook pro.)
Check out firewire, it'll tie with the fastest transfer your machine can handle, and it does not start and stop like USB so you get the gratification of watching a steady flowing progress bar.
If you desperately need faster transfers and have money to spend, here is how you do it:
Replace the drive in your machine with a solid state drive. Buy a 256 or 512GB solid state drive (large enough to enjoy, 512GB's are pretty expensive right now as they're a month old). Buy an enclosure from for the size of drive you bought and an eSATA connection. Put it all together and there you go: you'll get much closer to that max. Be sure to hit me up with your results, I am VERY interested to see just how much of an increase in speed you have. Whether other components are to blame.

Yes, according to the Asus website specifications on the A8V Deluxe you are able to run the CPU. You just have to make sure that the CPU you buy is for Socket 939 and not AM2.

Motherboard Issue

Hi Tomokato,
This maybe nothing but the first thing I checked is the CPU.
Supported CPU list through Asus web site for M2N-SLI
(Click on this link).
The first supported 64 X2 is;
Athlon 64 X2 3600+ (CU),512K,65W,rev.F2,SocketAM2
Second CPU supported;
Athlon 64 X2 3600+ (DD),1MB,65W,rev.G,SocketAM2

The CPU that you are using is not supported.
Since this is a new CPU, you might be able to exchange it for the Athlon 64 X2 3600+ (CU),512K,65W,rev.F2,SocketAM2.
Link to Asus main web site for M2N-SLI.
Suggest you add the above link to you're favorites.

Even you're memory is not supported. As seen in user manual page. 2-13.

Have more questions, feel free to ask.
