SSD data loss after a certain time?
Hey, I have a question. I once heard from an influencer that long-term storage in this case is an HDD or an SSD. I wanted to buy a hard drive for my vacation photos and other images that you generally save to take a bit of the load off the cloud. Now I've heard that if you don't connect the hard drive to it for a while, let's say after 2 or 3 years, the data could get lost. Is that true? Or does it really matter which hard drive I use, whether it's an HDD or an SSD? I need help. I just want something for all my pictures.

All chip-based data carriers need electricity so that they do not forget their data.
Of course, you can keep up without electricity for a while.
However, the statements are how long this is really good… let’s say “not clearly/consistent”. 😉
It is clear that SSDs speak here for years and not days/weeks/months.
But one thing is clear: Magentism in HDDs reliably lasts longer than the current in the storage cells. In any case, as long as you have no long-term measurements or experiences. 😉
Yeah, that’s right.
SSDs lose data when they are powerless and storage temperature plays a major role. After about 2 years without electricity.

What does the number of written terabytes mean?
The number of terabytes written indicates how many terabytes of data you can write to the SSD before reaching the end of their lifetime. This part of the service life depends mainly on how you use the SSD. If you overwrite many data, you get the maximum TBW faster than if you use the SSD on average. Do you want to know how many data you overwrite per year or per day? Then divide the number of TBW by the warranty period. With an SSD with a TBW of 500 TB and a guarantee of 5 years, you will transfer 100 TB per year or 274 GB per day.

An answer can be found using the example of the boot process of your PC: The computer recovers the operating system from the hard drive and writes it into the memory (RAM). This process takes place when the computer is switched on, since the RAM can write data only with a power supply. Now an SSD works with memory chips that are very similar to the memory, which is why one could assume that the SSDs also need a constant power supply to secure files. This is not true, however. Rather, flash memories use so-called NAND flash chips, which bring along another type of gateway wiring. It ensures that a certain power supply is maintained even when the system is switched off. In addition, the flash memory has a special property called “floating gate”. This is an electrical insulation that prevents external influences. Thus, thanks to these protective measures, it is definitely possible to say that an SSD is a suitable long-term memory. If the temperature at the storage location is constant at 25 degrees Celsius, the data will be stored for about two years. However, if it rises by five degrees, the life span is already halved. However, these data are very theoretical values. Because the actual duration up to data loss differs from model to model, as structural differences in production also play a role. In principle, however, you should not store an SSD in a warm but not too hot environment for more than two years without electricity, in order not to endanger your data stored on it.
Yeah, right. Take ne HDD.
