  1. 1. How many TBs have been written to your SSD?



Recommended Posts

Seemed like an awful lot.

Seems like an awful lot to me too. For comparison: your drive has 9,000 power-on hours. My drives have 19,000 power-on hours each, with 5 TB written to each drive in all this time. Because this is a three drive RAID 0 array, you can even multiply 5 TB x 3 drives to get a total of 15 TB data written in those 19,000 power-on hours.

Are you sure your are not running a defragger on your SSD?

I know it is very strange.

I am running Diskkeeper with what they call Hyper Fast for SSD's. Not sure if that would effect it.

I don't use Diskkeeper here, so I am not familiar with HyperFast. They do state, however, that "HyperFast SSD optimization technology uses specialized algorithms to reduce or eliminate free space fragmentation, while minimizing the number of file write operations it uses in the process."

So it seems to me that what it does is perform free space consolidation. As such, it is essentially half-defragging the SSD, which would increase the number of writes and possibly explain the 100 TB you are seeing.

I would turn it off and monitor how long it now takes to write another TB to the drive with it disabled, then do some quick calculations based on the power-on hours to see if it was affecting the number of bytes written to your SSD or not.

17TB, as much written and read (more or less) on an OWC Mercury Extreme Pro RE SSD. Performance of the SSD is still great

I have a 233 Media_Wearout_Indicatorof 7552, I don't know what that means exactly

64gb samsung 830 used as a boot drive for a couple of years in win xp, less than a year in win 7, and now back in a win xp PC. I store all the daily use apps like web browser, email, and my most played game on the boot drive.

Only 1.86 TB written to date.

I have a sick SSD. Telling me it's going to die any day now.

Says I have 9% life remaining.

147921186606 Logical Sectors Written

Sector Size: 512 bytes logical/physical

So 70,534GB or 68TB

No idea why it is so high. I do plenty of moving data around. Lots of work with virtual machines etc.

Not using any defrag utilities, the built in windows defrag scheduler shows "never run" on the C: drive, only on the secondary drive which is a standard 2TB platter.

RMA time. Going to pick up a new drive on the weekend and rebuild the OS. Probably time for that anyhow.

68TB may seem alot but the SSD should handle more. For example the guy in the below thread has written over 2000TB on his drive.

http://www.xtremesystems.org/forums/showthread.php?271063-SSD-Write-Endurance-25nm-Vs-34nm/page176

Storagereview even took a look at the peformance of a drive with 270TB written to it:

SSD Performance Review - 270TB Written

If you haven't picked up a new drive, I wouldL

1. Backup any important data

2. Check with another tool if possible.

3. Make sure the Firmware is up to date.

I have a Samsung 830 Series 128GB SSD, installed 25-July-2012 in my main desktop PC at home. I have pretty much everything writing to this drive. It's the Windows 7 boot drive, contains my documents, my Dropbox folder, browser caches, cookies, email folders, all program data and all file downloads get written here.

Total bytes written in 27 months of use: 10.19 TB

Just retired a Samsung 830 Series 256GB as well, it was also the primary system drive with everything being written to it-- granted there was a separate disk for bulk storage. After about 2.5 years of use = 10.7TB

Retired? I'll take it! 27.44TB written to my X25-m G2 80GB now. Still working great, though I may get an upgrade soon just because higher capacity and speedier ones are getting cheap especially if buying used.

Hey guys,

Curious how many Terabytes you have written to your SSD!

I have an Intel G2 80GB. So far I am at 3.78TB according to the "Host Writes" S.M.A.R.T. attribute available for viewing with the Intel SSD Toolbox.

I think most of it is because I was running my bittorrent client, which has a memory leak, and I left it running even though it used up all my free RAM and proceeded to use 9GB of my pagefile! SSD access was intense and this is probably was caused the large value, but I don't care! My system was nice and responsive despite having no free RAM. I kept it this way for days just because I wanted to see how far I could go.. I was running out of free space on the SSD for expanding the page file size!

Drive is still 100% reliable, 3 reallocated sectors.

How much have you written to your drive without failure(post if large # of reallocated sectors)? Any manufacture of SSD but if you have over 12TB you should post if it was an SLC or MLC or hybrid SLC/MLC type.

Mod edit: SSD Life can show how much has been written on the drive:

SSD will die.

Get ready for RRAM = almost immortal storage.

RRAM is also solid state memory. So there will be Solid State Drives (SSDs) with RRAM, if that stuff ever gets market-ready and proven in practice. Until then flash will have a nice time for at least a decade.

My Samsung 840 (TLC flash) now has 4 (four) TBW after roughly 3 years and starts showing read speed degradation. Down from 530 to about 160 MB/s for older files (stored about a year ago).

This lemon was the most expensive SSD i bought in 2013, two cheap and slow (IOPS) SanDisk G25s I bought along with it are still doing fine in linear throughput.
