Imho the writes are completely okay and 4 days is too short to tell anything for sure. My W7 system typically writes 5-10 GB per day. Take into account writes from W7 and other applications installation process. Also windows updates can generate much more writes that you could expect - for instance I have seen single updates (let's say about 100MB download, I don't remember the exact figures) that were able to write about 2GB during installation.
Thank you for your reply Bogdan Customer.
I actually checked the writes before doing Windows Updates so I understood the updates may have bumped up the total usage. (7-800mb update, approx. 20GB writes increased. )
But the real concern is that after all the optimization/configuration/installation, the writes are still increasing at the rate of 4GB/hours when the Resource Monitor in Task Manager shows the average writes of 10-50kb from the other processes including W7 System process. It just does not simply match.
Another fact that confused me was my friend's SSD info. He uses Samsung 840 EVO. He watches live streaming/youtube a lot, and does mild gaming (1-2 hours per day) which would surely write more on the disk than I do. But in fact, his disk info shows that it has been used for 479 hours with about 480GB writes. (which gives approx. 1GB/hours)
From several articles I have read, Recent SSDs can endure writes about 100GB/day for 7 years. and thanks to Intel's 5 years warranty on SSDs, I am not too much worried about my disk's lifespan. But I just want to figure out why numbers are not matching. Unless the writing rate is going to decrease somehow (I am not really sure this really gonna happen. paging is off and there are nothing left to optimize) I think it is better to figure out what's causing this overflow. It just does not feel good to know there is something that I am not noticing.
Sorry for making you unclear.
I was referring to the NAND Writes on the screenshot.
As of now, it doubled whereas host write only increased by ~12GB.
Most of writings(including cache created by web browser) are being transferred to HDD,
and only tasks done for the 40 hours of usage are web surfing and watching youtube videos.
Thank you for your interest, and I would really appreciate any further advice.
You are right. Imvho 94 GB NAND Writes related with 13 GB Host Writes on a fresh drive is uncommon.
That probably would not be a much of an advice however I have seen several similar instances on other forums and to be honest the only common point I think I could probably indicate were those additional "optimizations" like moving browser's cache and temp files to other drive and disabling other things. And Chrome appeared there too as far as I can remember. I think there was an assumption that it has something to do with moving browser's cache and temp files to other drive.
I refer to this since with Windows 7 installations I do not do any of those additional optimizations, I just check if the defragmenter is disabled and if the TRIM is working. Paging file, indexing and other things are on and writing to SSDs. I am well aware that these optimizations are being mentioned by all optimization guides out there but sincerely as far as I can remember moving browser's cache and temp files was the only common point without any other real clues.
What I see on my two Intel 530 series SSDs is: the F9 "Total Nand Writes" increases 1GB per 5-6 minutes no matter what you do, even when the drive is complete idle (no OS on it and no file access whatsoever). It seems to me that there is some internal housekeeping by the controller using the flash memory cells. Updating the firmware from DC32 to DCP2 (to prevent DevSleep) makes no difference. Please Intel explain what is happening, or at least try to reproduce the problem yourself which should not be that difficult.
