Worth upgrading 7 year old SSD?

[bug]

Just saying, I recall heat issues and NVMe drives. SATA drives don't have heat issues.

That's the problem, everybody "recalls" issues and keeps reporting them. But few people understand the issues.
The problem is that writing modifies memory cells. Writing uses power and generates heat. Where an AHCI drive will write at 500MB/s or so, a NVMe drive will write 4-5x as fast. That is what generates heat faster. However, to generate enough heat to cause throttling, you have to actually write 2GB/s for at least 5-10 seconds. How often do you do that, really?

Would I see any tangible benefit upgrading my old crucial M4 SSD to an m.2 drive when I build a new PC and carry across storage.

I've heard in real world usage it's unnoticeable but obviously benchmarks tell a different story...

Thoughts?

My experience, given the age of the drive it might be time and a good idea to get a new drive. I recommend an MLC based drive. Get a USB3 enclosure and turn your old drive into a backup drive.
