Does hard drive speed matter for loading and rendering? *solved*

I'm almost ready to order a 2.5 inch SATA hard drive.  I'm planning to move my Daz Studio and Poser runtime onto the new drive.  I'm not planning to do any animation.  If I do, I can always save the file onto the faster hard drive.  My Windows system and programs will not be on the hard drive.  I can't decide whether to buy a 5,400 or 7,200 RPM spinning drive.  I've heard that the 5,400 RPM hard drive producess less noise and heat.  The 7,200 RPM hard drive is $10 more.  Thoughts?

    it shouldn't affect render speeds, unless you are paging to disc (and have the swap fiel on that drive). It would affect load speed.

    I've seen a huge improvement when I moved some content to an SSD in loading time.

    My goal is to fit everything on a bigger SSD!

    For $10 get the 7200rpm. Things will load faster which is always good. That being said I haven't bought a 7200 in years. For things like my Daz content that can easily be replaced I use 2x 5400 drives in RAID 0 and get much higher performance than a single 7200 (not to mention that there weren't any 7200's available at the capacity I needed when I built my rig).

    SSD's are substantially more expensive but are also substantially faster, NVME m.2 drives are faster still and stand to make real strides on PCIE 4. However a 6 Tb SSD don't even exist right now, at least for commercial sale, and I have 4 6Tb HDD's in my rig right now.

    Ok, thanks for the info.  I'll go buy the 7200 RPM hard drive.  I'll keep an eye on the hard drive and CPU temperatures.  I'll buy another case fan if I need too.

    Usually a 7200 rpm HD is going to be around 30% faster than the 5400 rpm HD(not sure about the % speed difference between the newer drives). However, I should mention that things such as bit density of the HD platters(Gb per inches^2) affects the speed of the drive as well. Nowadays, spin speed isn't the only factor determining a harddrive's performance.

    Richard Haseltine brought up a good point: writing to a 5,400 RPM hard drive might be slow.  First, I need to copy 60 GB worth of files to the new hard drive.  Then I will store my Daz DUF and Poser scene files onto the new drive.  Daz Studio also creates files in the \data\auto_adapted folder.  Writing all of these files will take time.

    I might end decide to buy a 7,200 RPM hard drive bacause I'm going to transfer a ton of files to the new SATA hard drive.  The runtime folder for Daz Studio is about 60 GB in size and has a couple thousand files.  I'm also planning to copy the setup files for games that I bought to the new drive.  I might end up buying a 1.5 TB or 2 TB hard drive.
