The physical size of a hard drive is different from the nominal size of a hard drive. Nominal is derived from the word name, so the trade names for sizes of hard drives are 2.5", 3.5" and so on. If you were a hardware engineer you would measure the diameter of the disk that spins within the hard drive assembly. Because there is such a stark difference of one inch between the different trade sizes, it is easy to rule out by process of elimination the sizes that the hard drive is not, based on the total physical dimensions. Under no circumstances should you ever open up a hard drive to measure the size of the disk inside unless you possess the required skill, knowledge, & manual dexterity to do so successfully. If the hard drive that I hold in my hand has a width of 2.75", than it would be safe to assume that it is, in fact, a 2.5" hard drive because no other size disk would logically be expected to be used in that device. Always handle a hard drive by the edges, & never by the top & bottom for fear of caving in, even slightly, the top & bottom rendering it inoperable.
Normally by rotational speed (5200 RPM, 7200 RPM, 10k RPM, 15K RPM are common) or in transfer speeds by bandwidth (1.5 GBPS, 3 GBPS in SATA interfaces.) A more detailed performance mesure is by: * Sequential Read\Write Speeds * Random Read\Write Speeds * Burst Read\Write Speeds
what unit of measurement would u generally use for a hard disk drive?
This hard drive has a 100Gb internal cache.
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
If you are talking about the monitor size, it would be diagonal inches. If you are talking about the hard drive, it would be gigabytes or terrabytes.
The standard hard drive on the iMac as of 3/13 is 1 TB.
Yes, you can replace a hard drive in an HP laptop. Hard drives for laptops are a standard 2.5 inch size drive. You can pick them up online between $50-$200 depending on the size and if its solid state drive or a mechanical drive
Only as fast as its CPU. Doesn't matter the size of the hard drive - the hard drive does not determine processor speed.
Yes because both connectors are same shape and size.
