Do Not Use SSD to Store DATA

Do Not Use SSD to Store DATA
welcome back to my channel techtalk101sd. today we are going to talk about why you should not use ssd to archive data.

what does archiving data mean, like if you are thinking of buying an ssd to store data like documents, images, videos, or any kind of data and store it for a long time? then you might be making a mistake.

now imagine you have stored data on an external ssd and try to open or use that data after 1 or 2 years, you might see the data are corrupted or lost. yes, it is possible.

there are many benefits of ssd, after using ssd your system speed and performance increase. but as we know everything has two sides, so the disadvantage ssd has is data loss if you don't use that ssd for a long time.

nowadays everyone is using ssd, so if we don't store data in ssd then what should we use?
for archiveing data hdd is more preferable then ssd. let me tell you the reason behind this.

first we have to understand how ssd and hdd work.
SSD: Solid State Drive, it stores data as electric charge.
SSDs read and write data to an underlying set of interconnected flash memory chips. These chips use floating gate transistors (FGTs) to hold an electrical charge, which enables the SSD to store data even when it is not connected to a power source.

but until what time?
that is the most important point. when it comes to archiving data, that means we store data and might use it after 1 or 2 years. so we are talking about storing data for a long time.

why ssd should not be your preference let me tell you. if you store data for a long time and don't use the ssd in the middle, your data might get corrupted or lost.

why does this happen?
if you don't use ssd often. the data that was stored as electric charge, leaks out. this electric charge leak means data corruption or data loss. because the data was stored in that electric charge form.

This SSD charge leak process is called "tunneling effect".
to store data in ssd there are many transistors witch have floating gates and on their surface they have insulating layers witch store data as charge form, also preventing leakage of data. and works as a berrier. but over the time if we don't excite the charge, then after a period of time the electrons in floating gate through this insulating layer. leaks out by making a tunnel. and this is called tunneling effect.

tunneling effect is a quantum mechanical process.

now in hdd it stores data on a spinning disk, so it doesn't have the fear of this charge leak. so it is more preferable then ssd to archive data. if you have archived your data in hdd and try to check or use that data after years you can use that data.

now if you store data in ssd and connect it to power after certain days or period of time, then you will not have this problem. as the electric charge will get excited and your data will be safe.

hope you have learned something new.
