    Samsung Magician 4.9.7 Over Provisioning


    I did not like Samsung Magician 5.0 so I uninstalled it completely and installed Magician 4.9.7
    I like this older version, more "options", easy to work with.
    On one page they asked if I want OVER PROVISIONING, I chose "Set OP", it created a 47.69 GB "unallocated" partition.
    It is not formatted. Should I format it or just leave it alone ??

    Isn't over provisioning so as cells die the SSD will have replacement cells it can use. If formatted or used in some other way then it won't be available to SSD.

    I also think manual over provisioning is a thing of the past. The drive comes with memory it doesn't report to user to allow for wear and tear. 50GB is a fair bit of space but if you don't need it, you don't need it.

    Hi Ken, I noticed that the two Dell XPS 8700's I have with m2 SATAs on board, don't show overprovisioning so I've assume that Dell sets them up properly and that overprovisioning is hidden as you state. But I suspect that aftermarket SSDs, like for instance Samsung's, of which I have 3, do require overprovisioning by the user.

    I have a three year old Dell XPS-8700 with a newly added Samsung SSD, guess I'll leave my overprovisioning enabled.

    The amount of reserved space included on the SSD by the manufacturer for overprovisioning is completely up to the manufacturer. If you dig into the technical specs for the particular make and model of your SSD you should eventually find how much they have set aside for it and decide if you want to set aside more.

    SSD Over-Provisioning And Its Benefits|Seagate

    Read the part in the link about about Gigabytes (GB) v. Gibibyte (GiB).

    Personally, I don't set aside any additional space. As stated, if the user decides to set aside space on the SSD for overprovisioning, it needs to remain unallocated space that no partition is created or formatted on. As soon as a partition is created in that space then that space is turned over to the OS for use by the OS and is no longer available for the SSD firmware to use for overprovisioning.

    This article (in PDF form) is a lot easier to read and quickly explains what overprovisioning is and how it works.

    For clarity, all SSD drives ship with a pre determined amount of drive space already dedicated to OP - this is why your 512gig drive isn't fully 512 but instead 480gig. That's basically a 7 percent OP rate, which is pretty much the standard for SSD drives. Bear in mind nothing is written in stone so...

    And I agree with NavyLCDR, there's really, there's no need to increase your OP unless you are moving massive amounts of data 24/7. In short, for the typical home user, the default 7 percent OP is probably plenty, especially if you're nowhere near filling up the drive.

    Just a point, the reason a 512 GB drive only shows as 476.94 GB is not over provisioning but the disk manufacturers use of decimal numbering for the size versus the operating system that uses binary.
