An SSD is normally the best system drive
Solid-state drives start the computer and applications faster and have no moving mechanical parts. They are a strong upgrade for many older computers.
HDD still offers economical capacity
Hard disk drives can provide large storage at a lower cost per gigabyte. They remain useful for archives and backups where speed is less important.
Use both where appropriate
A desktop can use an SSD for the operating system and applications and a larger HDD for files. Important data should still be backed up because any drive can fail.
Check compatibility
Confirm physical size, connector and supported interface before buying an upgrade.
