SSD fragmented

[Deleted]

Hello. I'm aware that you should not defragment an SSD, so I've never done it. I've only had this new build for about 3 weeks and while my HDD is 0% fragmented, my SSD is coming up as 40% fragmented. I'm just wondering if this is normal for an SSD that has windows on it. If not, then I don't know why it's so fragmented as I've only installed windows, a few programs and WoW.

Fragmentation doesn't really matter when all the data is stored on memory chips, it isn't like the SSD has to move its drivehead to find the next part of the particular file you are trying to read.

Well, not exactly like that, but for simplicities sake yes.

SSD's are not effected by fragmentation as they have no physical drive head that has to physically move around the drive to get fragments of data. Instead it pulls all it needs in one stroke from everywhere it needs simultaneously. De-fragging an SSD puts un necessary wear on the drive. Because it literally does nothing for performance.

Also, where in the world does it say it's fragmented? My Crystal Disk Info shows nothing regarding this. I assume under Windows Defrag?

Don't worry about it.

Yes, in windows defrag.

Okay, thanks for the information.

I will echo the other ones and say that it do not matter. An SSD can "instantly" read from anywhere on the disk, while a normal HDD have to physically move the thing that reads data.

Does your windows defrag say that defragmentation is disabled for the SSD?

I notice you put word instantly inside quotation marks because it isn't actually instant. The more fragmented the SSD becomes the fuller the disk map becomes, the more space is used up on the SSD for the disc map not to mention half empty sectors, and the slower seek times become even though we're only talking about microseconds.

This is correct.

OT, what the OP didnt say is what version of Windows he had, if trim is enabled your drive should not be fragmented.

Disk Defragmenter was replaced with Drive Optimizer in Windows 8 (probably more of a name change than anything else) but one significant improvement is SSD handling. Optimising an SSD will run a TRIM pass instead of attempting to defrag it tidying up any blocks that may not have been TRIMed off at the time of deletion, for various reasons.

Check that your Windows OS has TRIM enabled. There is a possibility this may not be the case if you did not have AHCI (or RAID) enabled in your BIOS before you installed Windows (any version).

That said, fragmentation information from a normal fragmentation utility, like the Windows 7 one, is not useful for SSD. Indeed, if Windows 7 did detect any SSD drives, automatic defragmention would be disabled anyway.

All Windows 8 has done is essentially upgrade the defrag utility to make it "safe" on SSD drives. But it only does minor optimizations since TRIM support is enabled via normal operations in Windows 7.
