Be careful with the lifetime of data on SSDs (though not the drive itself unless it SW bricks itself), if you don't have it powered and/or you don't give it a chance to read and rewrite data. Especially at elevated temperatures and/or if the drive has been used a lot, maybe also with higher bits per cell.
We've had consumer drives lose data after only a few months if it isn't accessed, though that was at 60+℃, so data should last some amount of time in normal conditions.

- mceachen 5y agoCan confirm. SD cards can fall in 5-7 years due to cell voltage drift, and unplugged SSDs can have bitrot that overwhelms onboard ECC in less than a year. HDDs don't fare substantially better, though: bitrot can happen in under a decade due to magnetic entropy/polarization decay. Of course, your mileage may vary, and you may be lucky and get stuff off your 30 year old SCSI drive...
