Question about alignment on my Samsung 840 Evo

post #1 of 37
Thread Starter 
I have two 1 TB Samsung 840 Pro SSDs in my laptop

The first one was partitioned and formatted using the Windows 7 Setup

The 2nd one was partititioned in Windows Disk Management using the default allocation size

both are exactly the same, 1 partition each

Now when I ran AS SSD Benchmark, I noticed the OS drive is aligned @ 234496K and the 2nd drive is partitioned @ 132096K

1) How come they were aligned differently? Doesn't the Windows 7 Setup also align at the default as well?

2) Shall I format the 2nd SSD and align it the same as my 1st one?

3) When choosing the alignment sizes in Disk Management, I get 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K

I don't see any of the values above? so how in the world am I supposed to align the 2nd drive @ 234496K like the first one is?

PS: I did use Samsung Magician to Overprovision both by 10%

Both drives are aligned correctly. There is no need to make changes.
The way to check is to take the alignment and divide it by 1024. If it's divisible, the alignment is fine.
I checked both your alignments and everything is OK!

So it won't matter for performance? but what is the reason behind the different allocation size?

For best performance, 1024 is recommended. This can to be done during windows installation by using the Disk Part Command. Instructions can be found in Sean's SSD guide here on OCN. Just search for it.
As for the differences, they are different because Windows installation will use a different alignment to accommodate for the hidden boot partition. However, on your second drive, there is no other partition other than the Samsung Over provision, which requires no alignment on both drives.

Oh ok, I was worried I might be taking a performance hit on the 2nd drive.

Thank you so much for your insight Mr. Pro smile.gif

Hey no problem, your drives are fine and don't worry! Windows will never make a technically incorrect alignment. smile.gif

Here are my Benchmarks for my C: Drive using the Intel Chipset Drivers v9.4.0.1022

Then I benchmarked after installing the Intel Rapid Sotrage Technology Driver v.12.8.0.1016 and notice the huge performance drop.

I guess the Samsung Magician Rapid doesn't like the IRST Controller oy maybe because the drivers are not setup in RAID,

Either way, I reverted back to a system image before installing the IRST drivers and will keep it that way.

I've heard that IRST does not always help smile.gif
Do you have that special EVO setting enabled which uses the RAM and SSD together?

I used to ALWAYS install it for the past 4 years because when you google stuff about "shall I install IRST if I don't have RAID" most the forums replies you see will state that even if you do not have RAID, the IRST controller is better. I never knew I am hurting my performance until today when I formatted, I thought, wait a second, let me do a few benchmarks before and after and the difference is not small, it's mind blowing m8

Just leave it uninstalled then. On my system, it increases my speed by a good amount lol.
