'No Stupid Questions' (NSQ) Internet & Technology Edition

Is there a reason why SSDs are considered a poor choice for archival/long term storage (other than cost)?
SSDs can lose data when left unpowered for long enough. But exactly how long is "long enough" is the subject of many internet urban legends and nobody seems to know for sure. I've seen people saying it depends how many times the drive has already been written, exactly what flash technology is being used, the ambient temperature, etc.

Do they have some sort of internal battery that keep them in a low power state constantly even while unplugged?

My non-expert understanding is that flash memory essentially works by moving electrons around, and they just won't stay put forever on their own without a little electrical encouragement. (But they'll stay for some unknown amount of time, on average)
 
What can I use on Windows 10 to quickly and easily edit song titles, album names, track listings, and other metadata? Doing it through Windows File Explorer sometimes doesn't stick, disappears, or can't be edited for some reason.

I don't want something that automatically looks up names because I'm a weeb and I don't want all my vidya OSTs defaulting to Japanese.

mp3tag is far and away the best for this.

(For Linux people, puddletag is a lookalike that would be almost as good, but it has some very dangerous bugs or "surprise features" in copy/paste last time I checked)

No, since that wouldn't help. An SSD, or anything using flash memory for that matter, will (theoretically) lose data just as quickly regardless of whether it is powered on or off. It depends entirely on how recently the data was written, but every write wears out the memory cells and makes them more prone to data loss. If an SSD is powered though, it'll do the required maintenance, including refresh and so on, to ensure that data isn't lost just because it hasn't been rewritten in a long time.

SSDs use flash memory, which in turn relies on something called "floating-gate transistors". The simple explanation is that every SSD memory cell lets you store charge on a separate "floating gate", and you can measure this charge (without altering it) to read the cell. You can then map levels of charge into bits of data. On SLC SSDs, there are only two values, no charge and charge, while multi-level SSDs such as MLC, TLC, etc. have more levels which are then mapped into bits (as an example, TLC has eight levels of charge that are mapped into three bits).

The charge is kept on the floating gate by a layer of insulation (specifically an oxide layer). Changing the amount of stored charge (writing data) requires applying a high voltage, which damages the oxide layer slightly every time and makes it a worse insulator. Over time, the stored charge will leak out of the floating gate into the oxide layer and eventually so many electrons have leaked that your next data read will be wrong because the level of charge has changed enough. A worn out SSD will lose its data faster than a new one because the damaged oxide layer lets charge leak more. Multi-level SSDs wear out faster because the more levels of charge there are per cell, the more sensitive a memory cell is to leaks. The temperature and all that other stuff also factors into this.

Not really computer-related, but does anybody know how to properly clean the internals of a CRT TV?

Mine is fully caked with thick dark dust which is literally everywhere on the board and it doesn't seem to come off even with a paint brush and compressed air.

Probably there are 30+ years worth of dust in there.

Any tips?

Try to really get in there and touch as many large capacitors as possible with your fingers to discharge them, use a fork or a gold necklace if they're hard to reach. If they are discharged they can't kill you if you accidentally touch something you shouldn't.

Seriously, I've always been told to be careful around those.

Alright. I'll try using a small brush with some isopropyl to scrub off most of the dust.

The TV has been off for almost a year, so I assume it's discharged by now. Anyway, I know how to discharge them properly with a screwdriver grounded to the frame, shouldn't be too risky.

I know these type of TVs are dangerous, but I have to clean them up once in a while to avoid the internal components getting overheated by the dust inside.

Is there anyway to actually remove the scratches off any disc so that’s it’s clean and playable again, I can’t tell you how many games and Movies of mine have been fucked because of it. Is there any special wipe that can actually solve this lifelong issue of mine and millions of others?

If you can see through the scratches when holding it up to a light it's fucked forever, the foil layer is what keep the data. If it's scratches in the plastic that refracts the beam there's devices for that. Search this forum or the game forum for "resurfacing" (I think) and you will find a recent post about it that explains how it work and links to the things used that you can buy.
