Rpm is a thing to look at. A 7,200 drive is faster than a 4,200, but slower than a 10,000.

Uh huh, uh huh, uh huh, numbers....in.....ascending.....order.
Got it.
Sorry, RPM is rotations per minute. How fast the drive platers are spinning inside the drive. Also 7200 is fine for what you are doing.
One thing to consider here too is that faster drives are louder, run hotter (and thus need better cooling) and use more power.
For a LOT of home server workloads (streaming media, etc.) a 5400rpm drive is sufficient and you can have a little bit of power savings and less heat and noise as a bonus.
I've kinda become of the opinion that there's bulk media storage, which for most people is going to have incredibly modest performance requirements, and then there's eveything else and should be on a SSD anyways.
....Just avoid SMR if you're doing anything more than media storage.
God avoid SMR... (Unless you know what you're doing in which case you wouldn't be here)
10,000 and 15,000 rpm drives were made obsolete by SSDs and were discontinued several years ago. They are slower than many modern 7,200 rpm drives.
As someone that works at a storage devices company - we do still manufacture 10K HDDs. They are faster than the 7200s of the same spec, by nature. All 2.5” drives for enterprise systems. And will actually continue selling them until ~2030. That said, they’re all but obsolete at this point, and aren’t really being developed on any more.
