hard drives for sale

I have been building Windows Systems for many years, but it is time to downsize. I'm selling components I have collected over the years. These are hard drives, older, but all have been been tested and formatted with NTFS. They work fine. If any fail within the first few days, I will refund the purchase price. Prices as follows. 2TB - $30; 3TB - $40; 4TB - $50; 8TB -75. They are only going to be listed for a week, then donated or into the garbage. Thanks for looking.
