I would rather by NEW from Newegg or NEW OEM.

Had some manufacturer recertified drives that lasted a bit over a year. ST6000 and ST8000 something.

I thought my 18TB is biggest

HGST SAS here. Installed in 2016 and still running well

If the drive has Instant Secure Erase ISE or something, you can get it done in just few minutes. Data in rendered unreadable.

Just curious what is the advantage of using Cisco servers compared to Dell HP Lenovo? It seems to me they are all the same items under the hood.

80W for me in R730 running various VM and most of the time are just idle.

CPU wise , I prefer Optiplex. But R720xd will give you plenty of slots for storage expansion and more power consumption.

13th generation is 530 630 730 830 930 14th generation is 540 640 740 840 940 See the pattern. The latest is 16th generation.
