Disk R/W O?

[Op Point Baker]

This may not be the right forum to post this to, so if the Mods need to move it, go right ahead.

 

I've had Process Explorer from Sysinternals for a while now and there is something that I've been wondering that my google-fu seems to be failing to find an answer to.

I know what R/W for drive activity means [Read/Write] and I've gathered that the O means Other.

What constitutes an 'other' operation?

It seems to me like the only things you could do with a drive [HDD or SSD] is read or write operations. And, maybe more importantly, is it something I should be concerned about when it comes to SSD longevity?

[I'm running a full SSD rig, some are fairly old, so a drive failure in the next few years isn't beyond the pale.]

 

Thanks, OPB.
