It doesn't really matter if the SSD as a whole still works, because after 1000 years you'll never recover the data via the normal interface. Modern MLC flash is often specified for less than 1 year data retention, and even SLC is unlikely to make it to 1000 years. Attempting to read it will only make things worse ("read disturb"). The best hope of saving the data is with some future nanotech that directly probes each floating gate transistor and counts the electrons, and reverse engineering all the error correction and wear leveling.

I would assume they would read the SSD not by powering it on and plugging it into to a computer but by disassembling it and physically imaging the physical structure. This would also bypass the all the write leveling infrastructure allowing them to recover deleted data. It reminds me of the current techniques of using x-rays to read writing on the odd scraps of paper used to bind a book [0].
