ATA- 100 is an IDE interface ... that is, the theoretical maximum transmission rate reaches 100MB/S ... of course, it can't be that high in practice. ...

Now the mainstream hard disks are all SATA interfaces ... ATA- 133 ... that is, the theoretical peak speed reaches133mb/s/s. ...

I have to say, there is something wrong with what this guy said. SATA interface is a common serial port, and ATA is either ATA 100.

still

ATA 133

They are all parallel ports and IDE interfaces, not to say that ATA 133 is a SATA interface (serial port), but the transmission rate is different.

When changing the hard disk, you only need to pay attention to the interface problem. As long as the interface is right, it can be installed. Yours is ATA 100, which is a parallel disk. Just tell the merchant that you want to buy parallel plates when you buy them. Need to remind you that you'd better buy an ATA.

133, the hard disk transmission rate is high, so pay attention to the size of the cache. Of course, the bigger the better, the general cache.

2M

8M

16M

32 meters

Now it's usually 8 meters.

And remember that your laptop is a hard disk, just a 2.5-inch disk. This must be made clear, and don't buy a desktop computer then. Now 160G is around 250 yuan.
