In short you can explain an SSD (Solid State Drive) as modern HDD (Hard Disk Drive). What's the difference then? Maybe the functions are almost same but there are some big differences between the two. Go through the post to clear the concept . . .
What's an SSD
A solid state drive or SSD is a storage device that uses non volatile flash memory along with necessary controller and chipset to store the data. It's somewhat like RAM, but unlike RAM it can store data for a long period of time.
An SSD drive is considered to be more durable and stable in that sense - There is no moving parts i.e. platters, spindle, R/W head etc. which are available in traditional HDD.
Advantages of SSD over HDD
If you use SSD as your primary boot device instead of HDD then you may get the following advantages -
- Faster performance
- Lower power consumption
- Better vibration resistance
- Lower heat
- No noise
After installing SSD, you will enjoy the following benefits from your PC -
- Faster copy speed
- Better start up time of applications
- Faster installing of new programs
- Almost get rid of hangings
- Improved overall performance
Clearly there are some disadvantages of SSD but none of them is associated with performance and reliability.
- Price - This is the main problem of an SSD. At the price of a 240 GB SSD you can easily buy a 1 TB traditional HDD!
- Storage Capacity - SSDs are made for better performance rather for storing huge volume of files. That's why they are available at sizes - 120 GB, 240 GB, 256 GB, 480 GB, 1 TB etc.
What should you do?
Depends on your budget. There are 02 ways you can follow -
- If your budget is not limited then you can buy a 1 TB SSD replacing your old HDD. Certainly this will improve your system's overall performance. Or you can use more than one SSD if you need even more storage.
- If your budget is limited then you can buy a 120 GB/ 240 GB/ 256 GB SSD just for using it as your primary boot device. Additionally you can use a 1 TB (or more if necessary) traditional HDD for storing large volume of files.
