Hi, I have a T540p that has a 500 GB 7200 RPM hard drive in it. Previously, it would read and write near 100 MB/sec, which is to be expected.
However, recently it will only give me 90 MB/sec sequential read speed and 40 MB/sec sequential write. My external USB 3 hard drive is giving me 175 MB/sec read and 150 MB/sec write. Why is my internal hard drive so slow?
I can't find many tips on the internet but I've tried optimizing my drives, I've ran diagnostics on the hard drive, I've ran a virus scanner, I've done all my windows updates, I've checked the drive for errors but nothing has changed.
At what point do I reinstall the OS? Will that do anything? Should I send the drive back?
Thanks for your help.

Not that I know of. I installed a M.2 64gb cache drive and the FNET caching software but when I ran crystal disk mark and noticed that I was only getting 40 MB/sec write speeds I removed the cache drive, uninstalled the software, and did a system restore thinking the decrease in performance was related to the cache drive. That didn't help.
The SMART health says the drive is fine.

However, I did notice that for some reason when using PassMark disk checkup it says this drive is not Sata 3 compliant... why would that be? Could this be why it is running so slow?

I ran a benchmark using a bootable USB flash drive and it said the average read speed was 109 MB/sec (which is good) and the average write speed was 56 MB/sec which is much slower than it was a month ago when I bought this laptop.
There are no "reallocated sectors" or "current pending sectors."
All indications say that the drive is healthy and I can't figure out why it is writing so slow (comparatively) from when I got it. I intended this machine to be very fast (I realize that a spinning hard drive is a bottleneck) but that missing 30-40 MB/sec write speed has really got me puzzled.

I know that you know this, but in the era of SSDs, that drive is never going to be fast.
Not trying to be snarky at you. Get a Samsung and don't look back.
And for content, I would be suspicious of that drive's controller given the change and that you're in touch with your hardware in an informed way.
