During the single date sales, I managed to grab 2 4TB Seagate IronWolf HDD disk with a good price from Amazon. The storage of my unRAID tower has reach about 90% of 8TB after almost two years running. It is time to add.
After around 1 week waiting, two HHD disks were delivered into home with simple packing. I took about half way to install these two new hard disks and perform a maintenance with unRAID server. The last cleaning job was done 4 months ago.
After power on, the new disks are running well. Now, the usage disk is changed to 70% as new disks adding. It is a happy😁 shopping experience with Amazon.
