I'm looking to pickup some hard drives and setup a local NAS and start to archive information. I have seen too many things disappear recently and my internet has been getting worse - I am sensing that my ISP is starting to exfiltrate for the government and I have noticed some websites don't load via my ISP but they do via my cell phone and it's consistently dropping out a couple times a day and taking 3-5s for pings.....that is insane..... Anyone have some good suggestions for combinations and good quality at decent prices. Looking for robustness, no subscriptions, and ideally open source where available.
I want expandable options ideally that I can upgrade over time without replacing too much.
The internet has died....i need to gather what I can and back it up. I cannot trust the future any more. I need the data.
Tips appreciated
Do SSDs actually lose data when off? I read that was a misinterpretation and that only becomes true if an SSD is at end of life and already dying.
Yes. And more dense SSD lose data faster. It's just physics. Charge from isolated gates of flash memory leak due to non-ideal isolation and tunnel effects, so, earlier or later all charges will disappear. And smaller structures on crystal makes things worse. To be shure data will be OK you need to connect SSDs to power every week for few hours, SSD will run charge maintaining process.
It is about powered SSDs. Leak currents become larger with usage, and at some moment even powered SSD charge restoring process will not be able to mitigate that leaks. But even completely new SSD will lose data without power in relatively short time, from few years for old, low capacity SSDs made with process with high nm and months for new, current SSDs made with modern few nm process.
Same with USB sticks. Some old USB sticks may be could withstand many years, but I will not bet that new ones will last a year on a shelf.
In any case flash based storage is vulnerable to data loss and should not be used for critical data. HDDs, tapes and one-time recordable CDs/DVDs (not rewriteable ones) orders of magnitude more reliable for that task.
