    understanding reading and writing on SSD


    Good day.

    I was wondering if someone could answer the following.

    Whenever I copy from my C partition on an SSD and paste into a different storage device (HDD, USB flash drive, RAMdisk), am I reading and / or writing on the original SSD? More generally, what actions constitute writing on an SSD that can be reduced to lengthen its lifespan? Thank you for your attention.

    When you copy from your SSD you do not write to it.

    Your SSD is going to last for 50 years so there is little point in trying to improve its lifespan.

    Copying to another drive just reads from the SSD, and reading does not wear out an SSD.

    More generally, what actions constitute writing on an SSD that can be reduced to lengthen its lifespan?.

    Copying files to it, renaming files (that write to the directory entry), the system writing logfiles/registry/swapfiles etc. - basically any write operation will wear the SSD a little bit.

    Is this your first experience with an SSD? I was concerned about lifespan when I got my first one, but having used it for two years now I have stopped worrying - I calculate it's going to outlive me

    I have a 500GB SSD in one of my machines that gets quite heavy use (I run virtual machines on it). In 20 months it has recorded 11TB written to it (it's writing that wears out an SSD). At that rate I calculate it will take me another 40 years to reach the manufaturer's specs for 'total bytes written'. I suspect it's going to outlive me.

    Thank you for your reply.

    It certainly is. My concern is that CrystalDiskInfo shows a decrease of 1% in its health status every two months. Assuming the same constant decrease over time, it would take it around 17 years to reach 0%, but on the other hand, I imagine that a really dangerous level of instability will be well before it reaches 0%, am I right? Thank you for your interest.

    No, not really. Generally an SSD works reliably until just before the end, then fails abruptly. It take a lot to kill an SSD - and some have really tried....

    I never thought this whole tech journalism gig would turn me into a mass murderer. Yet here I am, with the blood of six SSDs on my hands, and that’s not even the half of it. You see, these were not crimes of passion or rage, nor were they products of accident. More than 18 months ago, I vowed to push all six drives to their bitter ends. I didn’t do so in the name of god or country or even self-defense, either. I did it just to watch them die.

    Technically, I’m also a torturer—or at least an enhanced interrogator. Instead of offering a quick and painless death, I slowly squeezed out every last drop of life with a relentless stream of writes far more demanding than anything the SSDs would face in a typical PC.

    If you have a desktop you can move some files and folders (virtual memory if you have a lot of memory, temporary files or even \users) to a HDD. I have done on my 120G SSD and after 5 years degradation is only 2%.

    Chances are, you will outgrow the drive based on capacity long before it's useful life is up. For example, I have a 10 year old Intel SSD that's 80GB in size. I don't use the drive anymore because, it's a slower SATA 300 model, and it's only 80GB. It still works through. but considering I can get a much faster 512GB model for about $56, I wouldn't use that old drive.
