Windows 7: SSD Defrag: New Info?

SSD Defrag: New Info?

Hi-

Please read this carefully, and please do not jump to conclusions.

I'm running a Samsung SSD 850 PRO 256GB drive for my OS (C:\; Win 7 Pro SP1 x64)) and a Seagate

Barracuda 1 TB HDD (D:\) for storage. I have moved Downloads, My Pictures, and Page File over to this

drive.

I stumbled across an article by Scott Hanselman, an MS Developer, who has explained the Win 8 and

Win 10 feature that automatically Defrags SSD's, once a month. Here's a link:

The real and complete story - Does Windows defragment your SSD? - Scott Hanselman

So, I ran an analysis of my Samsung SSD and this indicates 33% fragmentation. Furthermore, we have

run a Performance Test from within Samsung Magician.

We have perceived, perhaps, a slight slow down and a bit longer boot time recently. Of course, this may

be a figment of my imagination.

The purpose of this thread is to get some opinions on the matter BEFORE I run defrag and optimization

with Piriform Defraggler.

We've attached some screen shots that may help with opinions. The results from the Performance Test

are foreign to me- I truly do not know how to interpret the Read/Write values. Also, please note the

difference in Read/Write data between Jan 2017 and March 2017.

Thanks, in advance, for chiming in on this.

I've had problems using Defraggler with Win 7. I suggest using Win 7's defragger to check the amount of fragmentation and defrag only if it is over around 20%. I would not defrag over once every year or two to avoid unnecessary writes to the SSD.

I turned Windows 7 internal defrag back on and analyzed. Results: 20%

A 13% differential from Piriform Defraggler... Weird.

Thanks for your input.

Do you have Rapid mode enabled or something ? You`re not getting a true reading of your ssd`s speed.

Yes, I did... your numbers look far better than mine. Here's performance with RAPID disengaged...

Hmmm, why is this?...

"RAPID mode is a form of RAM caching for the SSD. Being as such, RAM is faster than an SSD by multiple orders of magnitude, which is why you see the results in the screenshots."

Back to the defrag deal... after much research, it appears that the advice from Scott Hanselman is bogus.

The notion that Windows 8 and 10 defrag SSD's automatically on a monthly basis is open to conjecture, and

if indeed true, may be a bug in those systems.

Furthermore, in both Defraggler and Windows 7's own internal defrag, the analysis aspect more than likely is giving

a false reading. Those programs are designed to analyze HDD's with a moving disc, according to studies I've found.

Piriform, on the other hand, claims otherwise-

Defraggler - File and Disk Defragmentation - Free Download

I'm having a difficult time finding the article with above info!- will post link when found.

I just discovered that I had System Restore turned on!... that MAY be causing low sequential read/write values.

Sequential write improved with SysRestore off-

Ya something`s a little off, my 850 Pro 256 GB gets over 550 read and over 520 write.

Having system restore should have no affect, I had it on why I ran my test.

Not that it should matter, but you should update to the latest Samsung Magician software.

Considering we're running HD 4600 integrated graphics... 116% SSD score...
