SSD benchmark, showing about 230 MB/s reading speed (blue), 210 MB/s writing speed (red) and about 0.1 ms seek time (green), all independent from the accessed disk location. Traditional HDD benchmarks tend to focus on the performance characteristics such as rotational latency and seek time. As SSDs do not need to spin or seek to locate data ...
A drive that implements S.M.A.R.T. may optionally implement a number of self-test or maintenance routines, and the results of the tests are kept in the self-test log. The self-test routines may be used to detect any unreadable sectors on the disk, so that they may be restored from back-up sources (for example, from other disks in a RAID). This ...
Some SSDs, including the OCZ RevoDrive 3 x2 PCIe using the SandForce controller, have shown much higher sustained write performance that more closely matches the read speed. [9] For example, a typical operating system has many small files (such as DLLs ≤ 128 kB), so SSD is more suitable for system drive.
A size comparison of an mSATA SSD (left) and an M.2 2242 SSD (right) M.2, pronounced m dot two [1] and formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and associated connectors.
The term solid-state became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology. A semiconductor device works by controlling an electric current consisting of electrons or holes moving within a solid crystalline piece of semiconducting material such as silicon, while the thermionic vacuum tubes it replaced worked by controlling a current of ...

Computer engineering – discipline that integrates several fields of electrical engineering and computer science required to develop computer hardware and software. [1] Computer engineers usually have training in electronic engineering (or electrical engineering ), software design , and hardware–software integration instead of only software ...
