Theoretically SSDs should last forever, but the more affordable type of SSD memory you get in consumer drives wears out a little every time you write data to it. Speeds of between 30MB/s and 110MB/s are much more typical. While high-end 7200 RPM drives can attain around 230MB/s and experimental drives have been shown hitting almost 500MB/s, the typical 5400 RPM drive you’ll find in a laptop or desktop computer comes nowhere near that. Traditional hard drives are the slowest of the bunch. If it hasn’t you’ll fall back to standard hard drive speeds. It also depends on whether the SSHD has pre-loaded the right files into the cache. So the larger the SSD cache, the longer the amount of time it can sustain high data speeds. Basically for as long as the SSD cache has data in it. Also, they can only achieve SSD speeds for short bursts of time.
SSHDs are only available as SATA drives, so they can never exceed the 600MB/s speed limit of the connection. NVME SSDs with read and write speeds around 3500 MB/s are commonplace now and a new generation of drive that runs in excess of 5500 MB/s is on the horizon. A good quality SATA 3 SSD will more or less hit the limits of the connection type with read and write speeds at around 600MB/s.īut SSDs also come in other formats, such as NVME. SSDs are the fastest type of drive in every comparison.
