The Seagate Barracuda is a series of hard disk drives and later solid state drives produced by Seagate Technology that was first introduced in 1993. [ 3 ] The line initially focused on high-capacity, high-performance SCSI hard drives until introducing ATA models in 1999 and SATA models in 2002.
This smaller form factor is similar to that used in an HDD by Rodime in 1983, which was the same size as the "half height" 3 + 1 ⁄ 2 in (89 mm) FDD, i.e., 1.63 inches (41 mm) high. Today, the 1-inch high ("one-third height", "slimline", or "low-profile") version of this form factor is the most popular form used in most desktops and data centers.
It was the first hard disk to fit the 5.25-inch form factor of the Shugart mini-floppy drive. It used a Modified Frequency Modulation (MFM) encoding [6] [7] and was later released in a 10 MB version, the ST-412. With this, Seagate secured a contract as a major OEM supplier for the IBM XT, IBM's first personal computer to contain a hard disk.

HDDs continued to get smaller with the introduction of the 3.5-inch form factor by Rodime in 1983 and the 2.5-inch form factor by PrairieTek in 1988. [ 21 ] Industry participation peaked with about 75 active manufacturers in 1985 and then declined thereafter even though volume continued to climb: by 1989 reaching 22 million units and US$23 ...
The specification was released on December 20, 2011, as a mechanism for providing PCI Express connections to SSDs for the enterprise market. Goals included being usable in existing 2.5" and 3.5" form factors, to be hot swappable and to allow legacy SAS and SATA drives to be mixed using the same connector family. [2]
M.2 form factor, formerly known as the Next Generation Form Factor (NGFF), is a natural transition from the mSATA and physical layout it used, to a more usable and more advanced form factor. While mSATA took advantage of an existing form factor and connector, M.2 has been designed to maximize usage of the card space, while minimizing the footprint.
The protective MBR is stored at LBA 0, and the GPT header is in LBA 1, with a backup GPT header stored at the final LBA. The GPT header has a pointer to the partition table (Partition Entry Array), which is typically at LBA 2. Each entry on the partition table has a size of 128 bytes.
