I have a brand new ASUS N76V laptop. The specs are:

Intel i7 2.4ghz 3rd gen
8gb RAM
Two 1TB hard drives--5400 rpm (Two partitions each)
GEFORCE GT 635M (2gb) graphics
Windows 8

The computer has not been running as fast as expected. The primary issue is data transfers and opening new programs. I know that 5400 will now be as fast as a SSD, but often when I open a program the HD goes up to 100% in the task manager performance section. The disk transfer rate also only goes up to about 10 mb/s, and is sometimes as low as 1mb/s. I downloaded a benchmark program which said I should be getting more like 55 mb/s. Both RAM and CPU stay below 25% when opening programs and during disk transfers.

I'm leaving for college in two weeks and I would like to know if there's a quick fix for this or if I need to send the computer back for a replacement/repair.

On another note, I may install my own SSD to replace one of the hard drives, but I think I should resolve the issue in case of faulty components before I replace any hardware.

Any advice on this would be helpful, but if it is the manufacturer's fault, I don't want to use any third party software to fix this or do anything to jeopardize the computer itself or the warranty.

Thanks

What are the make and model of the hard disks? I'm assuming Western Digital Green by the speed, but I'd like to know for sure.

Western Digital Green drives are absolutely atrocious for boot disks. They're designed for energy efficient mass storage, holding movies and music.

It appears to be a pair of samsung spinpoint M8s.

Here's an ID for it and a Newegg link: ST1000LM024 HN-M101MBB

Oh yeah, notebook drives are even worse. You're not going to get much throughput at all from those. I would expect close to the 55MBps mentioned with ~20ms read latency.

If you really want to kick your laptop up a notch grab some Seagate Momentus XT hybrid hard disks.

But I've never reached 55mb/s. Or even 20 to account for reading and writing simultaneously. For example, I'll open up a game like GTA IV and the Transfer rate drops to about 1 mb/s. Is this common? If it is I'll be buying a new SSD asap, but it seems like drives on other laptops I've used that are even more dated don't ever go that slow.

I have a similar problem. My specs are very similar on my lenovo laptop (3rd gen i7, 8 gb ram, 1TB hard drive (5400), nvidia GT640M). I get less than 1 mb/s read and write speed with the same maxed out disk but cpu and ram are very low still. Sometimes itll max out without doing anything and i never get read speeds near 55 mb/s. If anyone can help with this issue I would also be really appreciative.

Thanks!
