Increasing SSD Read/Write Speeds? Thursday, August 11, 2011 11:15 AM (permalink)
I have installed my OCZ Vertex 2 60GB and everything works, but since this SSD can read 285 /MBs and Write 275/MBs, I have it running on ACHI, and have all of those little fixes I can find to make your ssd faster ( superfetch, hybernation, indexing, all the stuff,)

My max read is 230 MB/s and max write is 48 /MBs any guesses how to increase write speeds?

      +1 to that. I need to get more knowledge with SSD's but since I don't have one it's going to be slow going with only theory and reading to gain the information needed. I'm sure Rafale has the answers you seek.

        Check to see if there is a Firmware upgrade available with OCZ. I've come across several other threads and the firmware upgrade resolved the issue. Also, check to see if there is an update w/ the BIOS.

            Ahh this was the thread that triggered the PM.
            I replied to the PM but I figured I could post something more complete here. The Vertex 2 is a Sandforce drive. There is a big debate over whether or not it has idle garbage collection. It seems even OCZ has provided conflicting statements about it. This means that TRIM is a must on this drive. I own one installed on a macbook and my write speed kept on degrading because I did not have TRIM enabled which is an indicator that GC does not work. I recovered speed only after enabling TRIM on my macbook but I upgraded the firmware at the same time.
             
            As I wrote in my PM,
            1) Try to upgrade the firmware. Your SSD is fairly small so I bet it wore out quickly. I am personally running 1.33.
            2) Do you know what version of the drive you received? Was it a 25nm or 34nm NAND? If you have the 25nm drive, you will need a newer FW than what I have.
            3) Make sure you have TRIM enabled:
            How to Enable TRIM Command

            In the Elevated command Prompt windows, type the following:

            fsutil behavior set disabledeletenotify 0

            How to Disable TRIM Command

            In the Elevated command Prompt windows, type the following:

            fsutil behavior set disabledeletenotify 1

            How do I know if TRIM is working in Windows 7?

            In the Elevated command Prompt windows, type the following:

            fsutil behavior query disabledeletenotify
            Results explained below:
            DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
            DisableDeleteNotify = 0 (Windows TRIM commands are enabled)
             
            If it all fails, I would backup my drive onto a hard drive and then run a secure erase using the OCZ toolbox.
             
            By the way how full is your drive? If it is close to full, there is not much you can do to improve the write because you will have very few available NAND cells to write to and the controller will have to go find them on the allocation table which makes the write slower.

              Thanks a lot rafale, I tried everything but unfortunately I didn't see an increase in performance.
               
              My drive has plenty of space, I'm only using 14.1GB of the 60GB.

              Maybe the reason for operation is the system reserve (100MB) partition windows made for some reason.

              How may I go about making an image of my hdd? Whenever I make a backup in windows, whenever I restore, it sucks, I have to re install all of my programs ( they're on another drive though )
               
              Thanks again however :)

                Try using clonezilla. 
                http://gparted.sourceforge.net/
                Since you have the 100mb partition, Windows probably already aligned the drive.

                  Alright, LOL I just followed a guide on how to get rid of that System Reserve."


                  So just clone, then use the ocz tool to erase?

                  and Re install windows ?

                    after the secure erase just clone the partition back onto the SSD. Just make sure you have the new partition aligned by making it start with a 1mebibyte (1024kB) gap at the beginning.
                    Also bench your drive right after the secure erase to see what its performance is when fresh.

                      alright, im not sure if Ill be able to clone the partition, but I'll use clonezilla and re install windows.


                      NINJA EDIT:

                      Second thoughts, Ill do it tomorrow, tired :( 
                       
                      Followup:

                      Hey so I backed everything up, I went to secure erase, and you can't do it to boot drives :/

                      Any suggestions?

                        I learned how to create a aligned partition offset (1024) You can do google search for this exact text...  
                        How to Increase SSD Write Speed | eHow. com
                        ehow. com/how_8744615_increase-ssd-write-speed. html#ixzz1uvJtoc2Q   (Remove space after each dot)
                         
                        There is one problem, most C:\ partition(s) use up the entire hard drive space and there MUST be room to create the alignment partition.
                        Here is how you make room. I am running win 7, you said that you have a 100MB(system) partition which is typical for win7/vista so I will  assume that you are not running XP. Right click on my computer choose "Manage" then choose "Disk Managment" Right click on drive and choose "Shrink Volume" I made it 10MB then choose "Shrink" Close that down and follow the instructions in the link above. now you have room :-) When verified and done go back to Manage - Disk Managment - right click on the 10MB volume that was created and choose delete volume. Then right click on C volume and choose extend and click ok. now you have the 1024KB at the begining of the drive right next to the 100MB system partition and have recovered your C drive space.  I have inserted the instructions
                        from the web page here and modified them slightly.
                         
                        Instructions
                        1. Click on the "Start" menu and select the "Search" box. Type "Command Prompt", then right-click the icon and choose "Run as administrator." (I just typed "cmd" then right clicked on the icon and chose run as Administrator, this skips #2 Instruction)
                        2.Enter the administrator user name and password to launch the elevated command prompt.
                        3.Create the aligned SSD partition by typing the following commands into the elevated command prompt window. Press the enter key after each command:
                        diskpart
                        list disk
                        select disk 1 (Note: replace "1" with the Number of your SSD  (Windows OS Drive)
                        create partition primary align=1024
                        active
                        exit
                        4.Verify the aligned partition by typing the following commands into the elevated command prompt, pressing the enter key after each command:
                        diskpart
                        list disk
                        select disk 1 (Note: replace "1" with the Number of your SSD (Windows OS Drive)
                        list partition
                        5.Verify that the partition was created by ensuring that "1024 KB" is under the "Offset" column in the information that is outputted after initiating the list partition command.
                         
                        Update... This process will make your C drive not bootable when you restart the computer after doing this.
                        Have no fear just have your win7 repair disk ready :-) Boot from it and choose repair my computer, it takes only a minute and puts the boot files in the right location on the drive. I verified after rebooting and the 1024KB offset is still there.
