A solid state drive (SSD)

It uses flash memory technology for persistent mass storage, offering significantly better read performance than the mechanical components in hard disk drives (HDDs), especially in read operations.uses flash memory technology for persistent mass storage, offering significantly better read performance than the mechanical components in hard disk drives (HDDs), especially in read operations.

Hard disk drive (HDD)

It stores data on metal or glass platters coated with a magnetic substance. Each platter has a read/write head on both sides, moved by an actuator mechanism.

RAID 1

a mirrored drive configuration using two disks

Distributed parity

error correction information is spread across all the disks in the array

Non-volatile storage devices, also known as mass storage

retains data even when the system is powered off.

The internal transfer rate (or data transfer rate)

measures how fast read/write operations are performed on the platters

flash drive

Solid state flash memory provisioned as a peripheral device with a USB interface.
