There are several options to increase memory of your device.

2. Pen Drive- Memory variable (2-128 GB usually), Transfer speed variable. (average 5-15 Mbps)
But still we needed more memory so Hard Disk came and took over.
3. External Hard Disk- Starts from as low as 8 GB and now 4 TB is also available in market recently. Here we can store anything we want. External removable HDDs typically connect via USB. Plug and play

storage options and portable design. External HDDs are available in 2.5"
and 3.5" sizes, their capacities generally range
from 160GB to 2TB. Common sizes are 160GB, 250GB, 320GB, 500GB, 640GB,
750GB, 1TB, 2TB, 3TB and 4TB.

But Now the main problem is you have to carry these device with you and have to connect physically with your pc which may not be possible in all situation.

To cope up with these problem now the tech giant came up with a new solution CLOUD STORAGE.
