Difference between ssd and hdd speed. A hard drive with a 5400 rpm will have a speed of around 100mbps. A typical 7200 rpm hdd will deliver a readwrite speed of 80 160mbs. As noted above an ssd can deliver a much better readwrite speed to an hdd.
A hard drive requires time to speed up to operating specs and it will continue to be slower than an ssd during normal. A solid state drive ssd is a newer faster type of device that stores data on instantly accessible memory chips. As there are no platters or other moving parts inside ssds the speed of ssds is measured in mbs.
A hard disk drive hdd is an old school storage device that uses mechanical platters and a moving readwrite head to access data. On the other hand a typical ssd will deliver readwrite speed of between 200 mbs to 550 mbs. An ssd equipped pc will boot in far less than a minute often in just seconds.
When it comes tossd vs hdd speed the solid state drive is the clear winner. Because ssd doesnt have any moving parts it can endure impact or vibration that is fatal to hdd. Until the late 2000s the world was simpler.
On the other hand an hdd with 7200 rpm will have speeds of around 150mbps. Therefore ssds are much faster than hdds. An ssd has an access speed of 35 to 100 microseconds almost 100 times faster than traditional mechanical hdd.
