what i was asking is if i have a really good ssd does the speed of the hdd matter for things like music pictures etc is there any point in getting 7200 rpm vs 5400 rpm
It matters when you are copying data to and from the HDD. Obviously, things only run at the speed of the slowest device in the chain. Here, the HDD.
However...your music playlist does not play any slower if it lives on the HDD. (this is a good thing)
7200 vs 5400? Which specific drive matters at least as much as the RPM.
My music library lives in the NAS box, on a RAID 5 of 5900RPM Seagate Ironwolf drives, accessed across the house LAN.
There is zero difference than if the music files were living inside this PC, on a Samsung 850 EVO.
For stuff you download from the interwebs? Your drive connectivity, even a 5400RPM, is much, much faster than the wire from your ISP.
Now...if you wanted to actually play games from that HDD, then yes...a good 7200RPM drive would make a difference.
It all depends on what you are going to use it for.
