I'm looking for a reliable way to store data for many years without worrying about losing it. Ideally, I want something I can save, store away in a wardrobe, and then retrieve years later with all my data intact. I've heard that SSDs, especially SLC technology, are good, but I'd love to get recommendations on specific drives or brands known for higher longevity. I'm open to business-grade options too, as long as they're accessible and not too pricey. I've also considered Blu-ray discs, so I'd appreciate thoughts on that as well.

If you're thinking about long-term storage, SSDs aren't the way to go since they can lose data after 1-2 years without use. Instead, I'd recommend M-Disc Blu-ray, especially the 100GB BDXL ones—they can last for over 1000 years! For a more practical option, a traditional HDD can also work well and should provide good longevity for under $100.
Most consumer storage isn't built for long-term archival purposes. If it's just a few years, most options should be fine, but consider having multiple copies. HDDs usually hold up better than SSDs over time. If you want archival tapes designed for long-term storage, there are options like LTO tapes, but they're not typical home use—usually more for businesses.
Definitely steer clear of SSDs for long-term storage! For archival quality, focus on optical drives. Properly recorded DVDs and Blu-rays can last a really long time if stored correctly.
How long are you looking to archive the data? If online storage is out, ranking storage media by longevity goes like this: 1. Optical discs (M-disc, CD-R) can last 50–100 years; 2. Magnetic tapes last about 30 years; 3. HDDs about 20 years; and 4. SSDs (the best being SLCs) are good for roughly 5-10 years. So I'd lean towards optical for the longest shelf life.
