Only 5 Power on hours, reads and writes are due to me being cautious and wiping ssd, check the disk info for more details, check pictures, the first 2 health info pics show the health before me wiping it, the second 2 shows after I did the wipe, I realized these were relatively new or new after I learned how to read the health, I have 8 of these and they are all in the same condition and guaranteed to work perfect, includes caddy, free shipping
