First thing I care about when buying a mechanical disk is dB / noise rating. It looks like the Seagate speaks to that. I like the enterprise drives which tend to focus on durability, power consumption, and usually noise. $70 is good for an 8TB enterprise disk IMO. I say do it. I don't get too concerned with not having highest RPM. Have enough RAM for them to read into and it will be fine. I'm using 5700 RPM disks they're performing well enough for me. If you are able to adjust the power saving features don't allow it to spin-down. It's less wear to spin it idle than to start and stop it for power savings. It's also a huge performance problem when you want to read the disk and have to wait for it to spin up to speed again. From the amazon page about this device I think I'd like it - especially for $70. I've always had good luck with Seagate.
