At this price point you really should be considering faster storage. If the cost of SSD is prohibitive, which it often can be, then one solution could be going with an SSHD (Solid-State Hybrid Drive). These drives (current Seagate branding:
FireCuda) utilize a small SSD cache for your most frequently accessed data so that you get faster load-time and performance, then also still has a larger traditional spinning storage capacity so you still get solid storage space bang for your buck.
If you'd like to see how these drives stack up in comparison to traditional HDDs and SSDs, here are a couple of charts you can check out:
The first one compares startup times across several popular games across a traditional spinning 7200 RPM HDD, our SSHD, and an M.2 SSD (128GB). The white is for SSD, the orange for our SSHD, and the gray for the 7200 spinning HDD.
Startup Times
The next one compares the first 3 days of gaming storage utilization across several popular titles, and SYSmark ratings from various drive types and combinations. First of the grays is 7200 RPM 1TB spinning HDD, second (lightest gray) is our SSHD, third (darkest gray) is an SSD + 7200 RPM HDD combo, purple is SSD + our SSHD combo, and lastly blue is SSD.
First 3 Days Gaming Storage Utilization
Good luck with your build, regardless of which drive you decide is best for your needs in the end!
