How do I configure Samsung 850 Pro for more overprovisioning?
How do I configure a Samsung 850 Pro for more overprovisioning.
With some other SSD's there was vendor supplied software that allowed you to decrease or increase the space that Windows and BIOS, etc., would see, so that you could interchange various size disks, even though some were 120gB, some 120gB, some 128gB, and some 128GB. You pick the smallest size (120gB) and set the other SSDs with enough overprovisioning so all have the same size in the Master Boot Record or Guid Partition Table; in fact, you could specify things so that even the 120gB file would have more overprovisioning than the disk manufacturer's default. However, when I tried the software that came with the Samsung UPC 8 87276 08430 5, Model MZ-7KE2T0 disk, the software refused to run on a new disk (no MBR, no GPT) and showed messages that seemed to indicate that all that would happen as that the MBR or GPT would hide some space (i.e., only increasing overprovisioning, not decreasing) from normal operating system programs. In particular I used: Windows 7 Ultimate. Connected drive to eSATA connection used Samsung Magician 4 from: CD: Samsung Solid State Drive One-stop install Navigator Manual & Software Version 4.5 {part number} LA81-01025A This has an entry for "Over Provisioning" under "SYSTEM MANAGEMENT" and the program displays in red: Uninitialized disk found. You can initialize the disk using... If you click on the link it opens It also displays in dark orange at some point: /!\ Note: Using a RAW partition may damage your data. OP can be set or cleared only from the last accessible partition. (If you use Magician with a partitioned disk it shows you the current partition layout and recommends a 10% increase in the "working" space, and show you which partition will be trashed if you have no un allocated space. This display makes me think that you could add some "working" space to an SSD that space not allocated to a partition and might even be able to get the last allocated partition shrunk, but this still would not produce the desired result, which is to have the overprovisioned space hidden from the raw partition or MBR or GPT, and also be able to decrease the "working" space for the controller at the cost of a shorter device lifetime. I called Samsung support and they said use Magician and didn't seem to understand that hiding space in the MBR was not the same as hiding space from the MBR. Does anyone know of a Samsung utility that will allow for decreasing and increasing the "working" space for the controller? Thank you. |

Rather than reserving unallocated space for possible future need, I just make sure the SSD partition is twice the size I'm ever likely to use. Then I keep an eye on it. That gives data plenty of "elbow room" and negates the possibility of any slowdown due to overpopulation. Larc |

Not sure what the BIOS has to do with overprovisioning. It identifies the geometry, hopefully, beyond which a successful format is liable to occur. The distinctions for interchanging brand/model, dissimilarities between "G and g," MBR, Microsoft GUID, *NIX schemes, are not contingent upon provisional utilities from Samsung, in any sense sole partitioning utilities. In fact, quite the opposite. Samsung's sole provision is in it's garbage collection software/driver interface to Samsung's proprietary controller, no other software developer may impinge upon without Samsung's blessings. Partitions, Samsung wants, very much so, to be broadly within industry standards, in order to sell the most Samsung SSDs as possible. If you want overprovision, then you'll need to partition a non-RAW compliant partition, i.e. Samsung's directive, and stop the OS from using it, so that Samsung's controller has full access for any/all over-partitioning benefits then, theoretically, to be derived. I don't see that, or know otherwise -- why, in the case of Windows 8, or 10, whatever you're running, should you over-partition with a *NIX file system, inaccessible to Windows -- the controller need necessarily be thwarted from the object;- no less so, extensively, than simply not assigning a drive letter to a NTFS, or FAT32, partition in Windows 8.1/10. All you need really to do is get beyond Samsung's garbage collection device drivers and interface, Windows 7 or a related update ID since is given, for any benefit, if at all, e.g. the stated industry SSD life projections over usages to degradation are, at present, largely neither of concern nor a disappointment expected or generally encountered. Good luck if you decided to accept the mission and over-provision with whatever else comes to hand apart from Samsung. Both my Samsungs are over-provisioned, as well a Crucial, although without critical firmware updates Samsung released as a result of an advertising-to-performance debacle which occurred perhaps a year or two ago. They're all also what I consider fringe managed, as my MBs were released well before SSDs hit their stride, mainstream;- I've hardly much practical interest in Windows 7, at present, near to none projected for Windows 8.1, and I absolutely detest Windows 10 for Microsoft's reptilian metamorphosis. - "I went from festivity to festivity. [...] it would seem to me—at the breaking point of fatigue and for a second’s flash—that at last I understood the secret;[...]. I ran on like that, always heaped with favors, never satiated, without knowing where to stop, until the day -- until the evening rather when the music stopped and the lights went out.” -- The Fall, Albert Camus. |
