*****Every SSD has been tested prior to listing and is in good condition. I am not familiar with the drive's health, nor do I have time to check the percentage on everyone that is listed. For my continued customers, you already know what I do for any of the inconvenience you may experience. For my new customers, please do not purchase if you feel uncomfortable because there aren't any refunds. I keep the prices low so you don't feel cheated if something is wrong. I would rather be an honest person before you purchase anything from me. I am definitely not here to take advantage of your hard-earned money*****
