Solid-state storage devices date back to 1956, when IBM invented the world's first hard disk.
What is a SSD drive?
A SSD drive, or SSD, is a hard drive made from an array of solid-state electronic storage chips. The SSD's interface specification, definition, function, and usage methods are identical to those of conventional hard drives, and its appearance and size are similar to traditional hard drives.
Advantages of SSD drives
SSD drives have fast read and write speeds
Unlike mechanical hard drives, SSD drives do not require magnetic heads and have almost zero seek time. Their continuous write speed is amazing, with many vendors claiming sustained read and write speeds of over 500 MB/s for their SSD drives. NVME SSD drives in recent years can reach speeds of around 2000 MB/s or even more than 4000 MB/s. The ultimate mystery of SSD drives lies in their fast random read and write speeds, which is directly reflected in most daily operations. In contrast, the most common 7200 RPM mechanical hard drives have seek times of generally 12-14 milliseconds, while SSD drives can easily achieve 0 or 1 millisecond or even lower.
SSD drives are shock-resistant and durable
Traditional hard drives are disk-type drives where data is stored in disk sectors. SSD drives, on the other hand, are made using flash memory chips, so there are no mechanical parts inside an SSD. This means that even when the device is moving at high speeds and tilting and flipping, normal use will not be affected, and the likelihood of data loss during collisions and shocks can be reduced to a minimum.
SSD drives consume less power
They require less power than traditional hard drives.
SSD drives make no noise
SSD drives have no mechanical motors or fans, so their operating noise is zero decibels. The flash memory-based SSD drives consume less power and generate less heat during operation, and they have virtually no mechanical moving parts inside, so they are free from mechanical failures and can withstand collisions, shocks, and vibrations, making them characteristically low in heat generation and fast in heat dissipation.
SSD drives have a wide operating temperature range
Traditional hard drives can only work within a temperature range of 5 to 55 degrees Celsius, while most SSD drives can work within a range of -10 to 70 degrees Celsius. Some industrial SSD drives can even work at temperatures between -40 and 85 degrees Celsius or higher. Compared to hard drives of the same capacity, SSD drives are smaller and lighter.

For an equivalent capacity, solid-state storage devices weigh less than mechanical hard drives.
