For your situation, I've had great luck with high-end SATA drives. I currently use the Samsung 870 EVO 2TB SATA III Internal SSD for my home archive. It has a solid 1,200 TBW rating and a 5-year warranty, which is killer for reliability. Bit rot is real, so I just plug mine in once a year to keep the cells fresh. Works great for me! TL;DR: The 870 EVO is a beast for long-term storage.

TL;DR from this thread: you've got solid suggestions for the Samsung and Crucial lineups already. To save cash while keeping high TBW, I'd suggest the SK hynix Gold S31 2TB SATA Gen3 Internal SSD. It's reliable, budget-friendly, and has a 5-year warranty. Just remember, for long-term storage, no SSD is a 'set and forget' solution—always keep a backup!

> I’m specifically looking for a 2TB drive with a high TBW rating and a solid warranty. Reliability is definitely my top priority over raw speed since these files are irreplaceable.

In my experience, if you're truly worried about longevity and bit rot, I would suggest looking at the Crucial MX500 2TB 3D NAND SATA 2.5 Inch Internal SSD. While Samsung is great, the MX500 has been a legendary workhorse for years with a really proven track record for stability.

That said, I've gotta be the "cautious guy" here—SSD storage for long-term cold archives (unpowered) makes me nervous. Honestly, even with a high-end drive, you might want to consider the 3-2-1 backup rule. Don't just trust one SSD! I'd recommend getting a solid drive like the Seagate IronWolf 2TB NAS Internal Hard Drive HDD as a secondary physical backup. HDDs are actually better for long-term unpowered storage because they don't lose charge like NAND cells do. Make sure to plug your SSD in every few months just to let the controller do its thing and prevent data degradation. Better safe than sorry! 🛡️

TBH, if you're looking at the market right now, you gotta look past just the TBW rating if you're serious about long-term data integrity. As someone who spends way too much time looking at controller datasheets, here are a few warnings from a market research perspective: - **NAND Type is everything:** The market is currently flooded with QLC (Quad-Level Cell) drives because they're cheap. For archives, avoid them. You want TLC (Triple-Level Cell) at a minimum because it has significantly better P/E cycles and voltage margin, which helps fight that 'bit rot' you're worried about.
- **Vertical Integration vs. Third-Party:** Brands that manufacture their own NAND and controllers (the top-tier global players) generally have much tighter firmware optimization than companies that just slap a generic Phison or Silicon Motion controller on third-party flash. This matters for how the drive handles background data refresh and error correction.
- **JEDEC Standards:** SSDs are technically rated for data retention based on specific temperatures (JESD218). If you store a drive in a hot environment unpowered, that degradation happens way faster than people realize. Basically, if a 2TB price looks too good to be true, it's likely QLC, and I wouldn't trust it for irreplaceable stuff. Stick to the premium brands that actually own their fabs.
