Finding the speeds of an SSD or an HDD can be confusing. One should not rely much on the connection speed, usually 6GBPS.
While the connection speed is commonly used in the industry, a hard drive will not deliver those speeds. The read/write speed is the most important statistic when it comes to HDD vs SSD speed.
A typical 7200 RPM HDD will deliver a read/write speed of 80-160MB/s. On the other hand, a typical SSD will deliver read/write speed of between 200 MB/s to 550 MB/s.
As noted above, an SSD can deliver a much better read/write speed to an HDD. When it comes to SSD vs HDD speed, the solid state drive is the clear winner.

Solid-state drives (SSD) overwrite data differently from hard disk drives (HDD) which makes at least some of their data easier to recover. Most SSDs use flash memory to store data in pages and blocks, referenced by logical block addresses (LBA) which are managed by the flash translation layer (FTL). When the FTL modifies a sector it writes the.
There is a major technical difference between SSD’s and HDD’s. SSD’s function on flash memory while HDD’s write to a physical disk. These technical differences ensure that HDD’s cannot compete with SSD’s on speed.
The read/write speed you will achieve when using an SSD or HDD will vary depending on the model chosen. Of course, an SSD with close to 550 MB/s read/write speed will cost more.
For certain tasks, maximum read/write speed is not needed. For basic PC usage, one could perhaps get away with using a lower speed drive. For most users a drive with faster read/write speeds is recommended.
