    Hibernation and SSD wearing

    ghost011

      Hello everybody,

       

      I'm planning to buy and install an X25-M on my notebook, but there are still some unclear points I would like to solve before proceeding. In particular, I would really like to know whether the hibernation feature in Windows OSs may actually increases the disk wearing significantly. A lot of users on the web recommend to disable it on SSD to minimize writes and enable longer disk duration, but I can't really avoid using it. It makes me save a lot of time, for I don't have to re-open my work session (about 100-120 running processes).

       

      Furthermore, I would like to know how the Data Migration Tool behaves in terms of partition alignment. I am not planning to make a fresh Win7 install, since it would take me too much to reinstall of my applications, and the DMT looks like to be excellent for that job.

       

      Thank you for your replies.

          When hibernate is invoked it stores a copy of the system memory on the hard disk. Disabling it therefore frees up disk space equivalent to the memory installed on the computer, which is why some people do.

           

          I wouldn’t worry about using it wearing out the SSD.

           

          If you have Windows 7 all you need to do is make sure you are in AHCI mode in the bios and then use the Intel Toolbox System Configuration Tuner to make sure everything is set up correctly and you are good to go.

           

          Regarding alignment if you are transferring a system image of Win 7 from HDD to SSD you should also be good to go.

            If you do hibernation about 4 times a day with about 4GB of data writes in that day to the SSD then you will likely get 3 years out of it maybe more.

             

            Use toolbox to check your media wearout indicator if it doesn’t drop by 1 after a months use it will then likely last over 3 years.

            If you can enable AHCI in your BIOS.

             

            As for the DMT I do not know if it aligns misaligned partitions to the SSD but its likely that if your partition is aligned now then it will be aligned for the SSD too when you use DMT.

              I usually hibernate with 2-2.5GB of used RAM, but I also perform more than 4 hibernate/resume cycles throughout the day. Point is, I frequently use VMs, too, and I tend to save their state instead of shutting them down. So I guess I stress my disk a lot.

                Oh, yeah, an additional question about DMT: my current partition is larger than the SSD I want (250 vs 120 GB), but used space is only 85 GB. Do I need to resize it before launching DMT or not?

                  Yes to the resize.

                   

                  Regarding the other issue Intel specs for the M series drives are a minimum of 20GB host writes per day for 5 years.  I’ve written 3TB to my drive and the wear indicator is at 98 (out of possible 99). I’ve yet to see anyone claim their NAND has run out of erase cycles and they have been around for a few years now.

                    Odds are it may work out fine for what you do and less used RAM when you hibernate the less that has to be written but if you really want to be sure you could wait for the 3rd gen X25-M that has four times more lifespan in writes then the 2nd gen X25-M.

                      This sounds comforting, don't really want to spend that money for a device I cannot stress as much as possible

                       

                      @PeterUK

                       

                      That's a big question. Actually, I do not desperately need a SSD, but whenever G3 comes up it won't probably be as cheap as G2 is. Have to think about it, but thanks for pointing out.

                        ghost, redux makes a good point, and I would bet that Intel is being conservative about those specs, as they would really hear about it from the industry and consumers if their SSD products did not at least match those specs.  I think the wear out issue with SSDs is nothing we need to be concerned about.

                         

                        That type of spec (longevity) has been overlooked in HDDs for years now, and of all the HDDs I've owned in the past that are over five years old (dozens) only two still function today.  I truly do not think you need to worry about wearing them out, even when using hibernation.

                          Thank you all very much for your replies, they really helped me. I think I'll order my new Intel SSD ASAP.

                           

                          BTW, I also appreciated the Intel Support Community web site very much: probably one of the best site I've been visiting so far.
