Presumably by size you mean capacity? The BIOS determines how much hard drive memory your computer can address so if you are upgrading your hard drive I suggest you check Toshiba's website and download the latest BIOS for your machine.
The price of a Toshiba portable hard drive depends largely on the size of the drive. The larger the drive the more the cost. However, the cheapest Toshiba portable hard drive in the US, brand new is $50 for a 160 GB drive.
Toshiba does not specify a maximum size hard drive for this laptop. Based on its age / date of manufacture, it was probably built around the time of the 2.1 GB barrier, and thus is already equipped with the largest possible drive usable under most operating systems.
The Toshiba Tecra 8000 uses standard 2.5" IDE / PATA hard drives. Depending on the size of the replacement (up to 127 GB should work), the price can range from $20 to $80.
This hard drive has a 100Gb internal cache.
You may choose any brand as they are all standardized and compatible.
The cache size is refers to the size of buffer on the hard drive. The bigger the the buffer, the less the hard drive has to access the drive. Also it improves the time that the computer needs to access data from the drive.
The percentage depends on the size of the hard drive. You would need to know the entire size of the hard drive to do the simple math. 4000000kb equals 4Gb.... now if your had a 100gb hard drive, that would add up to 4%.

The hard drive on a laptop is the same thing as the hard drive in a desktop, only smaller in size. The hard drive stores all your documents, music, videos and software.
every hard drive has only so much memory. the files size is there so you know how space it takes on you hard drive
In battery power it is 2.5 better that Toshiba. In size it is larger that Toshiba but not a lot.
The standard hard drive on the iMac as of 3/13 is 1 TB.
