I would normally disable disk defragmenter in Computer/Manage/Service and Application/Disk Defragmenter. Why is Samsung Magician requesting that it be turned back on for Over Provisioning?

i have the samsung drive and software and it doesnt state that for me.

it requires un allocated space (raw) to use\enable OP.

i have 2 samsung evos and disk defrag is disabled.

can you post a screen shot at all?

here is mine

Magician uses it to resize the partition. Just enable it, set overprovision then disable it again.

You don't need defrag enabled if you already have enough free, unpartitioned RAW space though.
 
disable disk defrag as you don't need to run it on SSD's

on the bottom right you will see a option to "set OP" click this and the software will do it for you but you will need the space free on the SSD before you can press the set op button.

What is OP?

An SSD controller is responsible for the massive task of managing all data traffic and storage for the drive. NAND technology’s intrinsic complexities require a lot of extra work behind the scenes. A data write is not as simple as placing data into an empty memory bank. Each NAND cell has a limited lifespan – it can only endure a specific number of data reads/writes. An additional layer of complexity is added by the fact that overwriting old data on NAND requires an erase of the entire NAND block (this same block may contain other data that is still valid). As a result, the controller is constantly moving data around to ensure that the cells wear evenly and to preemptively prepare “free blocks” to use for future data writes.
All of this management work requires the SSD to have a kind of “swap space” available to use as temporary storage while the controller goes about its business. The controller will use any available free space for this, but free space becomes a premium commodity as we fill our drives with data. OP is a way to set aside a minimum amount of free space, inaccessible to the user or the OS, which the SSD controller can utilize as a kind of “work bench.”

Not RAW partition, unpartitioned "RAW" space.

So if you have a 100GB drive and create an 80GB partition on it you will have 20GB of RAW unpartitioned space.

The OP space is created after Windows install. The Windows partition is already formatted to ntfs. So Magician uses some of this ntfs partition to create the OP?

Looks like you already have OP enabled.

It's a bit buggy when detecting if defrag is enabled, I had to fiddle with it after enabling defrag to get it to see it was enabled and remove that message about defrag. Try a reboot or changing the drive in the drop down to another if you have one and then back again.

Here's mine with the default 10% OP set.

do you really need overprovisioning if you have a lot of free space? you only need to reserve some if you plan on filling up the ssd

even with no overprovisioning and the ssd full,the ssd/controller should still be able to maintain the drive
 
I'm hammering the drives and don't need the space so just enable it to help keep the performance consistency. It may help keep write amplification down aswell.

I don't know why it's requesting defrag to be turned on. When I first tried to create the op, it wouldn't let me do it until I turned defrag bon. So I turned it on, created the op then disabled it and now it wants me to enable it.

I leave the defrag service on manual with the schedlue disabled so it spends it's time stopped. When I open magician and go to the OP section the defrag service starts. Have you opened up services and confirmed the defrag serive is actually started?
 
Just found this:

Quote:

"On Windows 8, the Disk Defragmenter is now named the Optimize Drives tool. It will optimize disks by defragmenting them if they’re mechanical or sending TRIM hints to them if they’re SSDs. This means that running another program that sends TRIM commands on a schedule is completely unnecessary on Windows 8, although even Windows 7 shouldn’t need this feature."
