In 1993, Seagate released the first Barracuda drive, with the ST11950. The drive had a capacity of 2.03 GB (1.69 GB formatted), was available with FAST SCSI-2 (N/ND models) or WIDE SCSI-2 (W/WD models) interface, and was the first hard drive ever to have a spindle speed of 7200-RPM.
The fastest high-end server drives of 2010 had a seek time around 4 ms. [14] Some mobile devices have 15 ms drives, with the most common mobile drives at about 12 ms [15] and the most common desktop drives typically being around 9 ms. Two other less commonly referenced seek measurements are track-to-track and full stroke.
In fact, it's the fastest external USB-C SSD on the planet, period. It touts blazing-fast data transfer speeds that max out at 980MB/s, but that type of speed comes with a steep price tag.
2009 - Western Digital is the first to offer a 1 TB hard drive in a 2.5 inch form factor.

The physical phenomena on which the device relies (such as spinning platters in a hard drive) will also impose limits; for instance, no spinning platter shipping in 2009 saturates SATA revision 2.0 (3 Gbit/s), so moving from this 3 Gbit/s interface to USB 3.0 at 4.8 Gbit/s for one spinning drive will result in no increase in realized transfer rate.
In order to market increasing drive speeds, manufacturers used the symbol n×, whereby n is the multiple of the original speed. For example, writing to a CD at 8× will be twice as fast as writing onto a disc at 4×. [2] There are two main types of disc speed, which are the angular and linear velocities.
Two 2.5" external USB hard drives Seagate Hard Drive with a controller board to convert SATA to USB, FireWire, and eSATA Current external hard disk drives typically connect via USB-C; earlier models use USB-B (sometimes with using of a pair of ports for better bandwidth) or (rarely) eSATA connection. Variants using USB 2.0 interface generally ...
