On SCSI hard disk drives, the SCSI controller can directly control spin up and spin down of the drives. Some Parallel ATA (PATA) and Serial ATA (SATA) hard disk drives support power-up in standby (PUIS): each drive does not spin up until the controller or system BIOS issues a specific command to do so. This allows the system to be set up to ...

That said, the price of high-capacity drives has fallen rapidly, and this is indeed an effect of density. The highest capacity drives use more platters, essentially individual hard drives within the case. As the density increases, the number of platters can be reduced, leading to lower costs. Hard drives are often measured in terms of cost per bit.
Solid-state drive (SSD) Hard disk drive (HDD) Price per capacity SSDs are generally more expensive than HDDs and are expected to remain so. As of early 2018, SSD prices were around $0.30 per gigabyte for 4 TB models. [23] HDDs, as of early 2018, were priced around $0.02 to $0.03 per gigabyte for 1 TB models. [23] Storage capacity
Cloud storage offers a convenient way to back up important files and photos, and even to maximize your hard drive space to store files you really need, rather than those you only access once in a...
This means the heads cover more distance per unit of time on the outer tracks than on the inner tracks. This method is typical with computer hard drives. Constant linear velocity (CLV) keeps the distance covered by the heads per unit time fixed. Thus the disk has to slow down as the arm moves to the outer tracks. This method is typical for CD ...
