Is my SSD unaligned?

post #1 of 13
Thread Starter 
I am somewhat experiencing slow read/write times, I changed around SATA cables and different ports on my motherboard but my windows boot still seems slow.

Here is a screen shot from AS SSD.

It shows its ok but what bothers me is that every other screen shot I've seen shows says 1024K but mine shows 103424K with an "Ok" status.

I tried backing up my partitions (restored using Acronis 2011 with the guide Sean made.)

Is it aligned or do I need to use GParted if it isn't?

You alignment is actually fine, as long as it says OK next to it you're good. I did some comparing of Windows alignment (what you have), 1024, and 4096 and 1024 came up with the best results (by a small amount). The results are negligible in real work tasks but if you are anal like myself you can do this to align it:

Installing Windows 7 on your SSD

1)Switch to Storage Setting to AHCI (refer to motherboard's manual)

2)Boot from the Windows 7 DVD

3)When you see the three options related to choosing a language, click Next

4)When you see the window with the big "Install Now" button, click the text below it that says "Repair Your Computer" to provide access to where we need to be

5)You'll see a little window appear named "System Recovery Options" which will immediately search for Windows installations

6)When it finishes, you will see a dialog box. Select "Use recovery tools that can help fix problems starting Windows. Select an operating system to repair." Now highlight the appropriate Windows installation and then click Next.

Start here if you are using your SSD as a Data Drive and Windows is already installed.
-Note: This can be done from a command prompt in windows or with Disk Management if you are using your SSD as a data drive.

7)Click "Command Prompt"

8)Type diskpart to load DiskPart

9)Type list disk

10)Type select disk 0 (or whichever number your SSD gets, the size should tell you which is drive is which)

11)If you want to be sure you have the right one selected, type list partition.

12)Once you know you have the right drive selected, type clean.

13)Type create partition primary align=1024

14)Type format quick fs=ntfs

15)Once its finished, Type active

16) Type list partition to verify the new parition.

17)Type exit

18)Type exit again

19)Click Restart

20)Boot from the DVD again and perform a normal installation using the "Custom (advanced)" type of installation. DO NOT FORMAT THE DRIVE AGAIN!!

The 100MB recovery partition is what causes the inflated number. But it is fine.

This what I'm getting. My read and write seem normal but it just doesn't feel like its running at what ATTO is reporting.

I'm not trying to be too anal or paranoid, but it just seems like it's not as fast as it was before. (I keep a majority of my programs on my 640GB while keeping just the essentials installed to the SSD).

Will try out your method though over the weekend. I've got nothing to lose tongue.gif

Ah ok. I didn't know the recovery partition would cause that. After seeing the numbers everyone else had I wasn't too sure if this was normal or if something was being reported wrong.

I wouldn't bother re-installing Windows over it - the size of the initial partition doesn't make any difference as long as it is aligned (evenly divisible by 4096 when expressed in bytes [or divisible by 4 when expressed in KB like AS-SSD shows it]), which yours is.

Here is a screen shot from AS SSD.

You have a SandForce 60GB SSD using asynchronous NAND. Those numbers actually look pretty normal for that type NAND and capacity.

As said you have good alignment. Running atto does nothing for you bud, tells you nothing. AS SSD shows your alignment, not atto.
post #10 of 13
I was showing him that the performance of his drive is fine. If it were unaligned, ATTO would not give those readings. And he has a SandForce drive, so AS-SSD won't give accurate readings.
