Among the industrial-grade SSD solid-state drive family, SATA, mSATA and M.2 forms are more common, but mSATA SSD has been eliminated by history, while U.2 and PCle are not yet popular.
The maximum speed of M.2 industrial-grade SSD can reach 32Gbps. The specifications are generally 42mm, 60mm, and 80mm7. The interface forms include PCl-Ex2, PCl-Ex4, and SATA. M.2 is currently the most mainstream high-speed SSD form. Using PCl-Ex4 channel and NVMe protocol, its maximum read speed can easily exceed the 3000MB/s mark.
The maximum speed of SATA industrial-grade SSD is 6Gbps, the size is generally 2.5 inches, and the interface form is SATA. 2.5-inch SSD hard drive 2.5-inch hard drive is a standard notebook hard drive, and SATA3.0 is also the most popular hard drive interface. Its biggest bottleneck is that the maximum reading speed is only about 550MB/s.
The maximum speed of mSATA industrial-grade SSD is 6Gbps, the size is generally 50mm, 30mm, and the interface form is SATA. mSATA SSD can be regarded as a mini solid-state drive. It was once the exclusive interface of early ultrabooks and fanless industrial computers, but has now been replaced by the smaller and faster M.2 SSD.
The maximum speed of PCIe industrial-grade SSD is 32Gbps, the size is generally more than 170mm, and the interface form is PCl-Ex2, PCl-Ex4. PCIe SSD can be directly inserted into the PC slot of the industrial computer motherboard. The PCB motherboard can be composed of multiple M.2 SSDs to form a RAID array. It is the most powerful hard drive form, but its high cost also destined it to only be used by a few enthusiasts. Exclusive to players.
The maximum speed of U.2 industrial-grade SSD is 32Gbps, the size is generally 2.5 inches, and the interface form is PCl-Ex4. Although U.2 SSD is still in the form of a 2.5-inch hard drive, it can achieve a transfer rate of up to 32Gbps and has a new physical interface. The cost of U.2 SSD is high and its popularity is not high, so ordinary users can ignore it.
