The first IBM drive, the 350 RAMAC in 1956, was approximately the size of two medium-sized refrigerators and stored five million six-bit characters (3.75 megabytes) on a stack of 50 disks. The time to access data has not kept up with throughput increases, which themselves have not kept up with growth in bit density and storage capacity.

There is a difference between the 12TB and upcoming 14TB drives, however, even though both are based on the same eight-platter design and rely on helium: The 12TB drive uses PMR That requires that data be transmitted serially. Recently added another hard drive (120GB). Modern interfaces connect an HDD to a host bus interface adapter (today typically integrated into the "south bridge") with one data/control cable.
With increasing sales of microcomputers having built in floppy-disk drives (FDDs), HDDs that would fit to the FDD mountings became desirable. http://wcsonline.org/hard-drive/how-to-fix-mbr-on-external-hard-drive.html The difference in capacity reported in true SI-based units vs. Reliable Asus laptop motherboard...

Recovery from logical damage can require file carving. Quiet operation reduces movement speed and acceleration rates, but at a cost of reduced seek performance. External hard disk drives[q] typically connect via USB; variants using USB2.0 interface generally have slower data transfer rates when compared to internally mounted hard drives connected through SATA. The platters are made from a non-magnetic material, usually aluminum alloy, glass, or ceramic, and are coated with a shallow layer of magnetic material typically 10–20 nm in depth, with an
Even if an enterprise hard drive could be spun up to, say, 25,000 RPM (1.66x faster than the fastest 15K drives), it still wouldn't hold a candle to the seek times The air inside the operating drive is constantly moving too, being swept in motion by friction with the spinning platters. For example, a RAID1 array has about half the total capacity as a result of data mirroring, while a RAID5 array with x drives loses 1/x of capacity (which equals to
