Originally released in 2012 for a whopping $1,550, thousands of Xeon E5-2670 CPUs hit the second hand market last year as massive data centers upgraded their servers. This 4-year old CPU delivers 8-cores clocked at 2.6GHz with a 3.3GHz turbo frequency and a large 20MB L3 cache. But with supply overwhelming demand, prices have plummeted to just $70, so it's possible to build an insanely affordable 16-core/32-thread beast for less than the price of a Haswell-E Core i7.
The DiskStation DS1515 is aimed at home users as well as small businesses. Out of the box this NAS can handle five 3.5" hard drives, giving it a maximum capacity of 40TB using the latest 8TB drives, while the addition of two DX513 expansion units boosts capacity to a whopping 120TB.
