In March of that same year, Intel entered the budget SSD segment with its X25-V drives with an initial capacity of 40 GB. [11] The SSD 310, Intel's first mSATA drive was released in December 2010, providing X25-M G2 performance in a much smaller package. [12] [13] March 2011 saw the introduction of two new SSD lines from Intel.
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 solid-state drive (SSD) provides secondary storage for relatively complex systems including personal computers, embedded systems, portable devices, large servers and network-attached storage (NAS). To satisfy such a wide range of uses, SSDs are produced with various features, capacities, interfaces and physical sizes and layouts.

Hard disk drives store data in the magnetic polarization of small patches of the surface coating on a disk. The maximum areal density is defined by the size of the magnetic particles in the surface, as well as the size of the "head" used to read and write the data. In 1956 the first hard drive, the IBM 350, had an areal density of 2,000 bit/in 2.
An M.2 2230 SSD, 22 mm wide and 30 mm long, with the key in the M position, and with a microSD card on top for scale. The large chip on the M.2 module is a single-chip SSD conforming to the M.2 1620 ball grid array (BGA) form factor.
Drives may slot into a drive bay of the corresponding size. Compared to flash drives in same form factor, maximum rotating disk drive capacity is much smaller, [citation needed] with 100 TB available in 2018, [1] and 32 TB for 2.5-inch. [2] The disk drive size, such as 3.5-inch, is usually refers to the diameter of the disk platters.
This method is sometimes called "SLC cache". It has two types of "SLC cache"; one type is static SLC cache (a SLC cache based on the over-provisioning area), another type is dynamic SLC cache (dynamically change its size on factors such as free user capacity). Toggle Depends
