WD is what I use for portable 2.5" 5400 RPM drives (My Passport), external powered 3.5" 7200 RPM hard drives (My Book), and NAS drives (Red 5400 RPM). I use these for storage.
For SATA OS drives in non-Macs, like the Intel NUC, I've switched to Samsung 860 EVO. The other SSD I'd consider is the Crucial MX500. If I wanted a HDD for internal use with OS and apps, or high reliability, I'd opt for the WD Gold Enterprise.
Most people also find WD's quieter in general in comparison to relative Seagate models. For example, I keep my Red inside a DS119J a meter away and I hear it only at startup when it spins up. At its normal spinning speed, its barely there and even if I hear it, it's not annoying at all. I've had other drives that were quite irritating. 5400 RPM from WD is my recommendation if silence is required.
