HDD vs SSD

HDD vs. SSD:- The alternative to hard disk drives is chip-based Solid-state drives. These are smaller, faster, and contain no moving parts, which makes them ideal for portable or smaller devices. Unfortunately, SSDs are still expensive in comparison and are susceptible to power fluctuations. From a data recovery perspective, it is usually harder to extract the information, but recovery techniques for these are improving all the time.

A comparison of the three main storage options
Pros
  • Large capacities
  • Relatively cheap
  • Greater tolerance to power fluctuation
  • Easier to extract the data if they do go wrong
Cons
  • Mechanical moving parts are susceptible to damage from knocks or being dropped
  • They are bigger and heavier than SSDs
Summary

If your device is sitting on a desk and doesn’t move go for an HDD, the greater capacity really is the huge selling point.
It’s better to have multiple HDD’s inside of a device rather than external cases as this offers greater protection.

Pros
  • Very fast
  • Small
  • No mechanical moving parts Can be moved around without fear of damage
Cons
  • Still expensive
  • Susceptible to power fluctuations
  • If they fail it is usually more difficult to extract the data than a HDD
  • Lots of fakes being sold online
Summary

If your device is moving around a lot (commuting or out in the field) then go for a good quality SSD every time.
If you can always use a surge protector on the device the SDD is in or plugged into.

Pros
  • Someone else is looking after your data
  • Accessible anywhere in the world as long as you have an internet connection
  • Easy to use
  • No physical drive to worry about
  • Small amounts of data are usually free or very cheap
Cons
  • Someone else is looking after your data
  • Moving large amounts of data can be slow and get expensive
Summary

You should have a cloud account, but look very carefully at what you actually get and make sure it has been set up correctly.
Internet speeds are a limiting factor, so a combination of physical drives and cloud is the best way to go.
Nothing is fail safe, we have done too many recoveries for data centers to trust cloud on its own.
