Detailed Breakdown of the Technology Used in Solid State Drives
Solid-state drives, also known as SSD in short, are slowly replacing mechanical drives in computers. Mechanical drives are large and bulky, consume more power, and have a higher breakdown rate. SSDs are slimmer, have faster transfer speeds, and are long-lasting. HDDs will remain relevant for a few more years, as SSDs are still expensive and will take time to become affordable enough to completely replace HDDs.

Here is a detailed breakdown of components used in a solid-state drive:
Connector: Serial ATA, also known as SATA, has been the standard for SSDs since its inception. They have already progressed to 3 generations, with SATA III being the latest standard. The connectors are still the same, with SATA I being compatible with SATA III connectors and vice versa. They only differ in terms of speed; SATA I supports speeds up to 1.5 Gb/s, SATA II up to 3 Gb/s and SATA III up to 6 Gb/s. Online PC adapters can be bought to connect SSDs and HDDs.
SATA Express: SATA express is a special port that can support 2 SSD at once. It is not that widely supported, although some older variants of MacBook do support it. However, one might need a MacBook Air SSD adapter in order to make it compatible.
U.2 Standard: It was bought in as a replacement for SATA express, and not many disks support this standard. It is relatively new and supports high bandwidths for newer SSDs. It is more compact as compared to SATA express.
PCI Express: It is a type of connector used by SSDs to connect to PCI boards. PCI board slots come in a wide range of connectors, and it is important to fit the proper connector in the proper slot in order to make the SSD run at its full potential. Many GPU cards that use this slot have many different configurations, and incompatibility with connectors can be a big issue for consumers.
Protocol 1: AHCI: AHCI stands for advanced host controller interface, and it is one of the oldest protocols in use for hard disk drives. These were originally designed to be used in magnetic hard disk drives, and some of the first SSDs invented made use of this protocol too. Being a legacy protocol, it does not support many of the modern standards and functions.
Protocol 2: NVMe: NVMe stands for Non-Volatile Memory Express. It is the newer protocol that is especially utilized for solid-state drives. While cheap SSDs still use the protocol 1, AHCI, high-performance SSDs that are designed for intensive work make sue of NVMe, and it supports only over PCI express based drives.
Most modern computers that some with SSDs have NVMe protocol in them, as it makes Windows 10 boot up faster. Older computers with Windows 7 or below definitely have AHCI protocol as NVMe doesn’t support older operating systems fully.
