They're just a silicon chip.
No moving parts.
Years or days. Impossible to tell.

Here is a really good article that will help you understand:
www.backblaze.com
In essence, even though there are no moving parts we can see, there are moving electrons, which do cause wear.
The thing with any silicon chip based storage is, it gives very little warning of an upcoming catastrophe. But when it does go wrong, it's is catastrophic!!
With normal discs, you have a glimmer of hope recovering files, even if in the extreme you take out the platters to get them read.
Are Solid State Drives / SSDs More Reliable Than HDDs?
It's good to know the difference between HDDs and SSDs and understand how the different SSD technologies affect reliability.

Quote from Ontrack data recovery specialists
"The downside of SSDs with the NAND Flash-based chips is that they have a limited life span by default. While normal HDDs can – in theory – last forever (in reality about 10 years max.), an SSD lifespan has a built-in “time of death.” To keep it simple: An electric effect results in the fact that data can only be written on a storage cell inside the chips between approximately 3,000 and 100,000 times during its lifetime. After that, the cells “forget” new data. Because of this fact – and to prevent certain cells from getting used all the time while others aren’t – manufacturers use wear-levelling algorithms to distribute data evenly over all cells by the controller. Firstly, all SSD devices have a maximum life defined by the number of times storage "
If you know the makes, most manufacturers supply free tools for checking SSD drives.. Western Digital SSD Dashboard is particularly good.
I have also used www.ssd-life.com tool which attempts to estimate lifespan

Samsung SSD's are probably the best ones. I am looking at building a new PC - and deliberating over SSD or HDD. Use SSD's/Optane for boot drives and back up to mechanical drives.

I have an old acer laptop that I installed an ssd in about 12 years ago. It runs my edrum software and midi controller.
The laptop hasnt been turned off in pretty much all those years apart from the odd power cut. It’s running 24/7 and still seems to be holding up Pretty well.
The drive must get hammered as the latency is tiny when playing the drums and it’s calling the thousands of drum samples after Calculating the velocity and position of each hit.

But that's about write cycles, what if you write a file and then only ever read it, and then only read it once per year?

Interesting point, without hours of research I would suggest that as SSD's use logic gates to store data, then decay is inevitable given time. Tests for powered down drives suggest data is still readable years later, some suggesting way beyond the life of the machine its in. However, other components such as capacitors in the device may fail if drive is powered but read-only.
That being said, having just billed a customer £900 to recover a 128 SSD that was only 2 years old (drive replaced under warranty) I would still suggest regular backups, when they fail they fail big time.
