Difference between HDD, SSHD and SSD
Comparison Chart
| Properties | HDD | SSHD | SSD |
|---|---|---|---|
| Speed | 25-100MB/s | Around 100MB/s | Around 500MB/s |
| Max Storage | 10TB | 1TB | 2.5-inch SSD: 15.36TB |
| Cost | Cheapest | Cheap | Costly |
| Full form | Hard Disk Drive | Solid State Hybrid Drive | Solid-State Drive |
HDD
The term HDD stands for Hard Disk Drive. This is the traditional memory drive which is being used in the computer. How a HDD works? It consist of many disks which are packed together. They spin and a magnetic reader reads/writes the information in it. This is the most used computer memory drive but latest computers started to use the SSD and the SSHD. So the usage of HDD will decline in the coming years. The maximum storage capacity of a hard disk drive is 10TB and its speed is slower than SSD and SSHD but this is the cheapest computer hard disk at the moment.
SSD
The full form of the SSD is Solid-State Drive which doesn’t have any movable parts and it works just like memory stick. Advantages: Data reading and writing speed is 500MB per second which is higher than HDD. A 2.5-inch SSD has the maximum storage capacity of 15.36 terabytes which is higher than the HDD. Disadvantages: The price of SSD is higher than the HDD. But the price will come down in the future.
SSHD
The expansion of SSHD is the Solid State Hybrid Drive. This uses the mechanism of both HDD and the SSD to store and processing the data. Pros: The data writing and transferring speed is 100MB per second which is higher than HDD but lower than the SSD. Currently 1TB is the maximum storage capacity of a SSHD but the capacity will be increased over time. Concerns: The price of the SSHD is higher than the HDD but lower than the SSD.
The hard drive’s speed of your computer is really important for gaming, multitasking and doing other heavy tasks. So, choose the one according to your need and budget.
