Quick 5 points you must look into are :
- Portability (External or internal hard disk )
- Max Transfer Speed
- Check support for operating system
Final Note :
If price is a big concern, go with a traditional HDD. If you’re buying the drive mainly as a backup or external drive, go with a traditional HDD. If the drive is going to run an operating system or hold a lot of frequently-accessed files and programs, go with an SSD.
