Windows 10: 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 ??

Very slow boot time with Windows 10 Pro on SSD

POSSIBLE SOLUTION: WINDOWS 10 UPGRADE DELETES OVER-PROVISIONING ON SSD!

After upgrading from Windows 8.1 to Windows 10 I experienced the same slow boot issues. This wasn't anything to do with what was happening IN Windows -- the delay was happening before Windows started, and continued after I rolled back to 8.1 (my Lenovo X220
was not fully compatible). I realized that it must be something that had changed on my SSD and I finally found out what it is:

The Windows 10 upgrade process deleted the over-provisioning space on my SSDs!! I had set up 10% for over-provisioning with Samsung Magician for both my Samsung SSDs and after the upgrade it was gone from both drives. After re-applying 10%
over-provisioning with Samsung Magician everything returned to normal after around 24 hours. It wasn't immediate, probably because the drive firmware needed time to get its references set up again.

If you have a Samsung SSD you just need to reactivate over-provisioning with the Samsung Magician utility. If you have a different brand you will need to re-activate it using the method you used to set it up in the first place. Make sure you have a backup,
because any changes to hard disk structure are potentially dangerous.

Info: Over-provisioning space is free space that an SSD needs to use to replace bad sectors. When sectors go bad they are marked as bad and the firmware uses sectors from the over-provisioning space instead.

 

Lots of BSOD's

Hello,

Installed all 3 of them altough Realtek PCI-E Ethernet drivers where already installed so i just clicked repair on that one.

It is a samsung 840 EVO 120GB

Freescan i did as well here is a screenshot of it:





Strange tough says in bottom right 99.8GB free yet in the program itself 90.4,i don't have anything enabled in samsung magician is set for max capacity

11.18GB is set for Over Provisioning

 

Why?

 

OK, Thanks Wannagofast !!

 

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.

 

I need to get a copy of the 4.9.7 software, do you still have it available?

5.1 added the settings back again so I would update to the latest.

 

Latest version isn't an option. I'm working on a drive that will never be connected to a network, and the latest version requires a network connection to activate HW encryption

 

You can find version 4.9.7 on this site, scroll down to the middle and its there..
