-
SSD (Solid State Drive): SSDs utilize flash memory to deliver faster data access and transfer speeds. They are more expensive but are ideal for users who require quick access to files.
-
Rugged Drives: Built to withstand physical shocks, moisture, and dust, rugged drives are perfect for users who need to store data while on the go, such as photographers and travelers.
-
Network Attached Storage (NAS): NAS units connect to your home or office network, allowing multiple users to access files simultaneously. They are suitable for businesses and home users with multiple devices.
-
Encrypted Drives: These drives come with built-in encryption to protect sensitive information. They are essential for professionals who handle confidential data.
