Will the IronWolf Pro 8TB fit in my NAS?
It is a 3.5-inch drive with a SATA 6Gb/s interface, so it needs a 3.5-inch SATA bay. Check your NAS maker's compatibility list to confirm support for model ST8000NTZ01.

How fast is the IronWolf Pro 8TB?
It spins at 7,200 RPM, has a 256 MB cache and uses a SATA 6Gb/s interface. The listing gives no sustained transfer rate, so check Seagate's data sheet for throughput figures.
