What is the lifetime of a modern SSD as the main and only disk in a PC?

Question

Solid State Drives

There is an idea to buy an SSD in a laptop, is it not very unreasonable to use it as the main and only disk that will be used to store both the OpenSUSE OS itself and documents (the heaviest files are mp3). The laptop is planned to be used actively for work + music. Or is the idea of ​​a single SSD not a good idea?

Answer 1

In this mode, as you described, the resource of an average static ssd with a capacity of 128-256 gigabytes will last for several decades. That is, the laptop will fail much earlier than the ssd runs out of resources.
Take for example ssd Intel SSDSC2CW120A310
Capacity 120GB, memory - MLS.
The resource for writing MLS memory is about 10,000 cycles.
It is clear that there is no ideal use of a resource, there are always overheads, but nevertheless, modern controllers work very efficiently with memory, and you can confidently count on at least 80% of the resource.
Let's take a minimum - a third of the declared resource of 3000 cycles.
So 120gb*3000=360000gb or 360 terabytes.
That is, it is guaranteed that 360 terabytes of information can be written to the disk until the resource is exhausted.
Now let's think about how much an ordinary user writes down information per day of work.
1) OS - in normal mode, this is tens of megabytes, occasionally if a major update is hundreds of megabytes per day, but this is rare.
2) Applied software and user - well, depending on which one, if you have a torrent client that downloads serials every day - then a lot, but how many serials fit on your 120GB disk?
Therefore, during normal work, an ordinary user usually writes about 1-3 gigabytes, rarely more.
That is, the average record for a day of desktop work is 1-10 gigabytes.
Well, even take 50 gigabytes.
360000gb/50gb=7200
That is, writing 50gb every day will exhaust the disk resource in 7200 days.
7200/365=19.7 That is, about 20 years.

Answer 2

It will become morally obsolete before it dies, forget about these myths, if you do not use the SSD on the server as a hot cache, then it will live for a very long time, if without a factory defect.

Answer 3

I live for more than a year and do not die yet, that is, it is already close to two, but at such intervals I just update them.
about several decades, the myth, of course , I
use ssd for the last 6 years
in the first years, they really worked for 3-4 months
