The Barracuda HDD series has speeds of 5,200–7,200 RPM, storage capacities of 500 GB – 8 TB, with max speeds up to 190 MB/s. The Barracuda SSDs come with either SATA or NVMe interface, storage sizes from 240 GB – 2 TB, and read speeds up to 560 MB/s for SATA and 3,400 MB/s for NVMe.
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

A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...
A current, widely used standard for the "buffer-to-computer" interface is 3.0 Gbit/s SATA, which can send about 300 megabyte/s (10-bit encoding) from the buffer to the computer, and thus is still comfortably ahead of today's [as of?] disk-to-buffer transfer rates. Data transfer rate (read/write) can be measured by writing a large file to disk ...
While traditionally these products have used HDDs, Western Digital has started to offer SSD versions, such as the My Passport SSD, its first portable SSD. [79] Western Digital external hard drives with encryption software (sold under the My Passport brand) have been reported to have severe data protection faults and to be easy to decrypt. [80 ...
SATA 3½-inch 20TB HDD, released 2022 SATA 2½-inch 500GB HDD, circa 2011. In 2001, the HDD industry experienced its first ever decline in units and revenue. The number of industry participants decreased to six in 2009 and to three in 2013. (See § Manufacturing history for more details) In 2009 – Fujitsu exits by selling HDD business to ...
Some SATA II and later hard disk drives support staggered spin-up, allowing the computer to spin up the drives in sequence to reduce load on the power supply when booting. [44] Most hard disk drives today support some form of power management which uses a number of specific power modes that save energy by reducing performance.
