Disable Superfetch if using an SSD as System Disk?

Topic

New Reply

I came across an article recommending users to Disable SuperFetch when using an SSD as System Disk in order to extend the life of the SSD

For those who may be wondering SuperFetch is a Windows service which preloads frequently-accessed files into memory for better performance. However, the article referred to suggests that this increased storage access speed is not necessary when using an SSD and only reduces the drive’s lifespan by constantly performing write operations.

The article further suggests, to disable SuperFetch:

•Run Command Prompt
•Execute “services.msc”
•Find SuperFetch and disable the service

Is this, in fact, worthwhile/useful advice? :confused:

See Disable Superfetch & Prefetch for SSD in Windows 10/8/7. It says Windows automatically disables SuperFecth when an SSD is detected.

Joe,

I checked this out:

So much for MS detecting my SSDs. The system I got the snip from has NO Spinning media just 2 SSDs.

I just checked “SuperFetch” in services on my main Win10 system (480GB Kingston SSD) and it was running. “Startup Type” was set to “Automatic”. I have stopped and disabled the Superfetch service and will see what happens.

Interesting question. A few years back, I put a Samsung SSD in my laptop. It came with a software program to optimize Windows according to one of three profiles that I could select. I can’t tell you if all three disable SuperFetch, but the default mode does.

On the other hand, I’m now using a MS Surface Pro 3 but there’s nothing in it that has disabled SuperFetch, so they don’t think it’s an issue. Of course, it may be self-serving of them to leave it running.

@Bruce,

Could be that SuperFetch does nothing even though it is running if it detects an SSD. Microsoft does some strange things.

Windows detects SSDs when it needs to. Although both Device Manger and System Information show my SSD as a Hard Drive, Defragment and Optimize Drives recognize it as an SSD.

Even with the Superfetch/Sysmain Service disabled, Bootrace, Prefetcher and Superfetch disabled in the Registry, *something* still runs Bootrace. Perhaps I’ve missed something, or maybe MS flipped a switch in a WU. W7 Pro. x64.

This is a machine that I’d briefly tested W10 AU on and then reverted, it’s also possible that the bug crept in there, I guess,

Yes; My Windows 10 setup does not appear to have disabled SuperFetch (indicated as “automatic” in Services. I have disabled it and so, too, Prefetch …(waiting to see what happens!! So far, so good!!)

Maybe SF is like Defrag, works differently for SSDs.
