The first HDD [11] had an average seek time of about 600 ms. [12] and by the middle 1970s, HDDs were available with seek times of about 25 ms. [13]Some early PC drives used a stepper motor to move the heads, and as a result had seek times as slow as 80–120 ms, but this was quickly improved by voice coil type actuation in the 1980s, reducing seek times to around 20 ms.
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. The first, the SSD 510, used an SATA 6 Gigabit per second interface to reach speeds of up to 500 MB/s. [14]
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 ...
Seagate announced launch of Barracuda 7200.12 on January 5, 2009. [54] SATA 6 Gbit/s models replaced SATA 3 Gbit/s models in January 2011. Barracuda 7200.12 drives were also available under Maxtor brand, the model name under this brand was DiamondMax 23. Only SATA 3 Gbit/s models were available under Maxtor brand and was the last generation of ...
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.
