Upgrading laptop hard drive that uses ATA-7 interface

freedomispopular 1,272 244 January 29, 2011 at 08:41 PM
I have an HP dv6000 that's almost 4 years old, so a while back I was looking to possibly upgrade my hard drive. The one I have right now is a Toshiba MK8037GSX. When I read the system specs on the computer it said the hard drive is IDE, so I thought I wouldn't be able to upgrade, but then when I actually took the drive out and looked at it, I realized it's actually a SATA drive, but I noticed it has some kind of adapter on it. After doing a little Googling, I found out that even though the drive is SATA, it uses an ATA-7 interface. I was hoping to possibly get an SSD, but I'm assuming that since it uses the ATA-7 interface, no matter how fast my drive is, it'll be bottlenecked by the ATA-7 speed. Is that correct, or would it still be faster?

Any sata hard drive should work fine in there. Many laptops use special connectors to make removing hard drives easier and it has no effect on the actual hard drive. A ssd in the laptop will not be much faster than a newer 7200 rpm drive on a sata 1 interface. While it will have much lower seek times and random reads the overall transfer will be similar.

your existing drive IS an "sata 2" (SATA 3.0Gb/s) drive according to specs at toshiba and newegg...

it's just not a very fast one.. about 24-44mb per second read/write speed (from hdtune graphs found via web search).. compare to a new 500gb scorpio blue at 39-79mb per second. a 500gb scorpio black peaks at just over 100mb per second.

ssd performance varies greatly. the early models or cheap current ones may barely beat your existing drive, while the fastest (and more expensive) ssd would be limited by your laptop's sata port capabilities (whether it be version 1 or 2 of sata specs). also remember that ssd performance is fairly consistent across the entire device, while mechanical drives are only fastest on a portion of the drive (roughly the "first" 15-25% of the drive).

you will see some performance boost in moving to SSD but imho, spending money on 4+ year old consumer laptop when not absolutely necessary is a waste. if you need a new or larger hdd today, pick up a 250-320 scorpio blue or similar for around $40 or less. it will be faster, it will be bigger, but it won't cost you either.

Thanks for the info. Another question: if I were to get a new hard drive, how would I go about cloning my current hard drive onto the new one?

There are may drive cloning programs, Google for more details and review. But I have had luck with:

I might suggest taking a look at the Seagate Momentus XT. It's a hard drive with a 4GB flash drive attached, which can speed boot times and commonly used applications. I believe it comes in 250, 320 and 500GB sizes. Best yet buying a Seagate drive gets you a free download of DiscWizard from Seagate's web site. DiscWizard is a free limited version of True Image, which should clone your drive quite nicely.
