How important is SSD alignment?

post #1 of 13
Thread Starter 
So I finally got around to installing Windows 7 on my SSD (Corsair Force 115GB) using the Win 7 SSD's Setup and Secrets thread here on OCN as a guide. Of course I did not read through the thread's OP thoroughly enough before getting started and, as such, I did not do the alignment step before I installed the OS (I did do all the other configuration tweaks afterwards).

Results are as follows:





Write speeds on the Crystal Mark are troubling but a number of sites have mentioned that the CrystalMark test doesn't do well with SandForce drives, so I'm taking that one with a grain of salt... ATTO results are right on track with the advertised speeds.

So my question is, should I align the disk using TwoCables' alignment process or should I just let it ride the way it is now? Will alignment increase longevity or performance in any noticeable way?

it isnt really that necessary otherwise it would be included in manual.
Also if its fresh install windows pretty much does everything automatically. The only thing you have to do manually is to switch IDE to AHCI in bios before installing it.

Good luck... I had some problems with my first ssd, which failed after one week.

I have to admit that I only know of one benefit gained by aligning the drive to 1024 KB: optimal performance. I mean, I haven't looked into it enough to know if there are other benefits.

Anyway, you must've done something right because my CrystalDiskMark results are inferior to yours:





However, I honestly don't care what my results are because the real-world performance is great (it's way more than I actually need). Plus, I put more stock in ATTO's results:





I ran this right after running CrystalDiskMark, so my write results are probably lower than they otherwise would have been if I had ran ATTO first. Either way, it looks to me like you're kickin' ass.

However, I'm curious about one thing: do you have Intel's Rapid Storage Technology driver? It kinda looks like it, but I am still curious!

Oh, and can you open AS SSD and post a screenshot of it? You don't have to run its benchmark; just post a screenshot of it sitting open. There are 2 things I want to scope out!

Yes is installed the Rapid Storage Technology driver shortly after installing Windows.



That's all you want??

AS SSD says that your alignment is ok!

It says 103424 K - OK

Plus, I see "iaStor"!!

Everything's looking great!
