HAL was a Christmas present. He addressed my wife’s need for a storage strategy for her digital photographs, amongst other things. Within the family I was widely known as a geek. The fact that she welcomed a NAS as a gift cemented her standing in that regard.
HAL was twice upgraded such that he presently sports five 2 TB Seagate Barracuda hard drives configured for RAID 10 + a hot spare. One drive failed a couple of months ago. At that time it pulled in the hot spare, spending a weekend rebuilding the volume. No data was lost.
