This is a used Samsung 256GB SSD - it's essentially an OEM equivalent of the 840 EVO. It's pretty old flash, so despite the fact it's in great health currently, you probably shouldn't keep anything too important on here. Then again, it's MLC flash, so it could go either way. I'll leave the NAND Russian Roulette to you.

I'll ship via USPS in a bubble mailer. I'd prefer to only ship to the continental US, but SSDs are so light that if you live in Canada or something we might be able to work something out - DM me on Discord: Miranda#8080.
