Toshiba Satellite A30 Notebook Hard Drive

Hi, I have to replace my notebooks hard drive, it's a Toshiba Satellite A30.
Here are the specs of the oroginal hard drive:

Make: Hitachi
Model: HTS428080F9AT00, HTS428060F9AT00,
Interface: ATA-5 (Ultra DMA mode-5)
Capacity: 60Gb
RPM:      4200


I found many hard drives on eBay that have better performance.

My questions are the following:

1) What maks should I avoid ?
2) is ATA-100 the same thing as ATA-5 ??? (I'm confused)
3) Can I put a SATA or ATA-6 instread ?
4) Is the number of pins on the hard drives the same with SATA, ATA-6 and ATA-5 ?
5) Is the difference between SATA, ATA-6 and ATA-5 only the speed, and all the rest (including the number of pins) the same?

Thanks!

You will definitely notice a difference going from a 4200rpm drive to a 7200rpm drive !!  (the difference in buffer sizes is much less significant)

On a laptop, you should use the same interface type as the old one; so you cannot install a sata drive instead of a ATA drive, since the physical and electrical interface is different.

The 4200 rpm speed is not so important on a laptop, as tha faster it is the noisier it is as well.
Replace it with a normal ATA laptop drive. We normally recommend Hitachi (3 yr warranty) or Seagate (5 yr warranty).

You can use any ATA-6 drive up to 120GB with no problem.  Above that you MAY have a logical block addressing problem -- so I'd simply not go with any higher capacity.   Do be sure you don't buy a serial ATA drive (newer laptops are beginning to use them).

I would also recommend you buy a 5400rpm drive;  they have appreciably better performance than the 4200rpm drives.

The # of pins is standard -- the new drive will fit just fine.

There are many choices -- simply buy one from a reputable manufacturer (Hitachi, Seagate, Samsung, Western Digital, Toshiba) and you'll be fine.

Hi garycase, actually I ordered an ATA-6 80Gig hard drive with 7200rpm (Mitsumi). Do you really think I'll feel a difference with the rpm and the 8mb buffer instead of 2mb?
