I've seen your other posts, you're a smart guy. We can be more technical then this. I've read that link and do you know what I see? A bunch of people who have never looked at their hard drive activity before reading that thread and most haven't actually looked to see what's causing the activity even after posting in that thread. Here's my system right now, with PIA connected and no running applications besides Chrome.
Yep, sure enough, PIA's client is writing 40kb/s. Usually less (20kb/s), occasionally more. But what's this? Chrome is writing 318kb/s while sitting there doing literally nothing. Fresh Chrome session, the only thing open is the tab with this reply in it and that's after turning off Chrome's option to keep running the background. Open Firefox and let it sit at Google.com, there's another 100kb/s. Have any applications that keep themselves updated? That's going to be writing too. Have Steam? You're going to freak out when you realize how much data it's typically writing due to updates. Use a chat program? That's probably logging too. God forbid you're using Outlook in a Corporate environment.
The reason that stands out is because you're looking at a computer that's doing basically nothing at the time. Open up some browser tabs, maybe download some updates. That 40kb/s is going to get lost in a hurry. Let's look at the big picture here. You posted your crystaldiskinfo over in Memory and Storage recently of your "old" GSkill Sniper. My current main SSD has a higher write per day average by almost 30%, so let's stick with yours to make PIA look as bad as possible.
Your drive has been powered on for 676 days and in that time written 5.81TB of data. That's roughly 8.59Gb of data a day. Let's go absolute worst case here. Let's assume PIA logging is running high at
40kb/s and you leave it on and connected every waking second of the day. That's 3.45Gb a day. That's not insubstantial, however you're at 5.81TB after going on 2
years of power on time. Assuming the above worst case of PIA being on and connected 24x7 at the above constant 40kb/s, that would put you at 7.31TB after 2 years instead of 5.81TB.
A quick search didn't turn up the write endurance for your GSkill, but the economical MX100 is rated for 71TB. That's almost 20 years of writes even factoring in worst case PIA usage. I've got almost 70 drives in my house (Spindles + SSDs) between desktops, laptops, tablets, and servers and not a single one is anywhere near 10 years old nor do I expect to have any of them after 10 years. That thread is people making mountains out of a mole hill.
Then there's people saying it's "bringing their system to it's knees". They're either full of shit, or they have something seriously wrong with their system. Would I prefer it use less? Sure. I'd also prefer Chrome use way less resources. But I'm not going to stop using Chrome because it might be shaving a few months off my SSD's life. Not to mention if it's still a concern after considering those numbers, don't install it on an SSD. Use an internal spindle, or an SD card, or shared storage, or a RAM disk, or better yet, don't leave it running 24x7. It takes 10 seconds to boot a system running off a decent SSD. There's no shortage of ways of reducing or eliminating that write usage.
