In this video, Hard Disk Drives (HDDs) and Solid State Drives (SSDs) have been compared in different aspects like storage, cost, speed, and performance, reliability etc.
Comparison of HDD and SSD:
1) Speed: In terms of speed, SSDs are much faster than HDDs.
2) Storage Capacity: Modern day HDDs have storage capacity from 1TB to 10TB. While SSDs have storage capacity from 120 GB to 4TB.
3) Cost: SSDs are much costlier than HDDs. Cost per Gigabyte for SSD is almost 3 to 4 times than the HDDs.
4) Reliability: SSDs are more reliable than HDDs and less prone to accidental damage.
5) Power Consumption: As hard disk involves the mechanical moving parts, the power consumption of HDDs is more than SSDs.
6) Data Durability: HDDs are more durable than SSDs.
7) Form Factor: HDDs are available in 2.5 inches and 3.5-inch form factors. While SSDs are available in various form factors. (SATA, mSATA, and M.2 SSDs)
The timestamps for the different topics covered in the video is given below:
