This is an unwanted replacement hard drive (Intel SSD 520 Series 180GB). Sale due to deciding to replace it with a 3TB Toshiba drive to one I already have in order to set up a mirror RAID.
You are welcome to test this with your favourite disk health utility and I also have a brand new one sealed up but if the drive health turns out to be perfect then you are committed to buying it as it won't be worth as much to the next buyer if it's unsealed.
Cash on collection only please from EastLondon E14.
