    Lightbulb SSD writing limit, how to determine current SATA writing value?


    Hello,

    i read that SSD is better than SATA, except writing and so far higher price for capacity, mainly its limitted by writting.. so i want to ask how i can see current writing value of my SATA HDD to see if SSD drive in its place wont die too quickly?

    quotations:

    SSD Write operations: 0.01 - 5 million per cell
    source: Why SSDs? - Why are Solid State Drives much better and faster then normal Hard Disk Drives - SSD Reviews, Data Sheets and Comparison - ssdreview.com

    It seems my computer does roughly 1 gigabytes worth of writing in two hours. By doing a quick calculation a 128G SSD with 3000 write cycles would last 90 years... Nothing to worry about.
    source: linux - How to get total number of bytes/sectors/blocks written to disk since booting? - Unix & Linux Stack Exchange

    "iotop" command shows average writing rate 5Mb/s

    cat /sys/block/sda/stat

    thx

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    The longevity of the device depends entirely on the controller software on the "disc". If it's write-leveling software is good, then it will last a long time. That said, I would NEVER (at this point in time) use an SSD for swap space. SSD is great for system files that are mostly read-only. As for a 90 year life-cycle? Nice dream! Theory and practice rarely meet in reality...
    Sometimes, real fast is almost as good as real time.
