I just purchased an SATA hard disk (seagate). &nbsp;It supports 3.0 transfers but my PC only supports 1.5 transfers. &nbsp;The drive comes with a jumper that limits it to 1.5 by default. &nbsp;No problem and everything works right.<br />

SATA 1.5 vs 3.0 - What's the jumper behavior

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.
