How many M per second are hard disk read and write speeds
Mechanical hard disk read and write speeds average 60—80M per second. Between the different brands and models of solid state hard disk, the gap is very large, the average is about 150—300M per second.
Mechanical hard disk read and write speeds average 60—80M per second. Between different brands and models of solid state drives, the average is about 150—300Mbps. 5400rpm laptop hard drive: 50—90MBbps. 7200rpm desktop hard drive: 90–190MBbps. Read and write speeds of SSDs can reach 500MB/s.
As of 2015, the read speed of mainstream 5-inch branded portable hard drives is about 50-100MB/s, and the write speed is about 30-80MB/s. Most of the portable hard drives use the USB and IEEE139eSATA interfaces, which can provide high data transfer speeds.
What is the read/write speed of a mechanical hard disk versus a solid state drive?
Generally about 5 times, mechanical hard disk read/write speed is about 100MB/s, while many of the solid state hard disk can reach 500MB/s, or even higher.
1, solid state hard disk has a great advantage in the transfer speed, up to 500M / s, which read speed to 400-600M per second, write speed can be as high as 200M per second. For 1G files can be done in just a few seconds, while the traditional IDE hard disk read speed limit is unable to exceed 200M per second, write speed is also difficult to break through 100M per second.
2, the reading speed here refers to the continuous reading speed, the actual calculation, due to the ordinary hard disk and seek time and other overhead, so in fact, solid state hard disk reading speed to reach the ordinary hard disk 7 ~ 8 times more. The difference between a solid state hard disk and an ordinary mechanical hard disk is still very big, regardless of the read/write speed or price, there is a huge gap.
