SSD vs HDD

DO you know – just by upgrading your hard dsk of your PC or laptop, the performance enhances phenomenally. A user can choose to go for SSD or HDD according to his/her preferences.

SSDs are expensive, but with years of experience with computers, I will prefer SSDs instead of a hard disk with TB’s of space.

Here’s the key comparison table for your reference:
