Is my SSD "data written" counter bugged?

post #1 of 9
Thread Starter 
I have a Samsung 830, 120GB.

I still have 32GB free, haven't filled it even once.

SSDlife says the following:

1085hours worktime, powered on 41times (I don't shut my computer) and, here's the interesting fact:

Data written: Total 423GB.

Is it data read+written or what? Because I made sure to:

- Move the pagefile to another drive
- Relocate the temp and tmp folder to another drive
- Disable hibernation

I'd move the appdata folder if possible, but I'm unsure if it's worth it.

Anyway, am I missing something? The drive is at most a month old, and it has no writing applications (it mostly has games, and any application that uses the temp folder will surely use the other drive, not the SSD. And if it did use the SSD, I'd notice the free space going down).

Looks correct to me. That is data written.

Don't worry about it anyway - you can write hundreds of terabytes to the drive without it failing. The whole SSD lifespan was completely overblown.

And I'd move the pagefile back - if you are going to have one, it is beneficial to have it on the SSD.

I'll give that a try, would a 512MB pagefile be sufficient?

I'm still unsure how could have I written so much data on the drive although I'm not really using it. Is it from browsing, do all the videos and images get cached on the ssd?

Average use is about 10GB a day. Your power on hours = 45 days. * that by 10 and you are under average biggrin.gif

Windows makes many logs and updates to system files that you can not control. Plus yes, all your web browsing gets downloaded and cached to the drive.

Nah. For a non-power user, it's closer to 5GB/day.

As for the page file, as long as you have enough RAM, it's unlikely to see much use. Frankly, I haven't noticed any significant increase of host writes with the page file on the SSD as opposed to having it on a secondary HDD.

Back when 32-40GB SSDs cost $150-200, it's understandable trying to remove as much stuff from the SSD as possible. With 120/128GB capacities available for $60-80, though, it doesn't make sense anymore. It's unlikely for the average user to use up all the P/E cycles on 100+GB MLC SSDs (3,000 P/E cycles minimum * 100GB = 300TB NAND writes; equivalent to 275GB/day for 3 years or 165GB/day for 5 years). I don't understand the rationale of buying an SSD to speed up your system and then moving all the things that would benefit from the SSD (cache, temp, page file, etc) to a slow HDD. I bought an SSD to speed up general, everyday computing, not for the e-peen factor of short boot times.

Lol, even for power users, 5-10GB is the norm. I remember Anand's SSD article from back in 2009/2010 and his usage was around 7GB/day average or something. tongue.gif

Interestingly enough, it seems usage on my SSDs in various systems range from 2-20GB host writes per day (not counting systems doing HTPC duty - those run 40-100GB host writes per day).

My old 60GB Vertex III showed 1.2TB written, after owning it for a year or so. I wish my Crucials had a counter as well...
