Restoring Your Drive to Peak Performance

Based on my explanation there’s one sure-fire way to make your drive fast again. Formatting/deleting everything on the drive won’t work because those pages on the drive will remain full of data.

If you are doing a clean setup of your machine and want to restore your drive to its native state you’ll have to perform a secure erase. Intel distributed a tool with the first X25-M review kits called HDD ERASE. This tool will take any SSD and free every last page on the drive. Obviously you’ll lose all of your data but your drive will be super fast again!

In order for HDDERASE to work you need to have your SATA controller running in Legacy IDE mode, you can select this in your BIOS. Your drive will have to be connected to one of the first four SATA ports off of the controller.

Boot to a command prompt (I just use a bootable DOS image on my USB stick) and run the executable. Answer its questions carefully and with honor.

Tell it you would like to perform a secure erase (an extended one isn’t necessary) and when it asks you if you wish to view LBA 0 you can say no. Reboot your machine (don’t forget to set your SATA controller back to whatever mode you had it in before, e.g. RAID or AHCI), partition your drive and you’re back in business.

On a good SSD I don’t believe there’s a need to secure erase periodically, but whenever you format or re-image your drive, I’d recommend a secure erase since you’re killing all of your data anyway.

    I just got the Apex. I'd probably cough up more dough for the Vertex after reading this. However, I've run it for two days as my system disk in MacPro and haven't noticed any issues, it's really fast. But I guess I'll get Vertex for my Windows 7 build.

    What I find intriguing about this article is that these smaller manufacturers do not do real world internal testing for these things. They should not need 3rd parties like you to figure this shit out for them. Maybe now OCZ will learn what they need to do for the future. Reply

    Thanks for an excellent article. I have one question does anyone know which controller is beeing used in the new Patriot 256GB V.3 SSD?

    Anyone know if the Vertex Anand used had 32M or 64M cache? Reply

    Can't remember what page it was, but you showed some charts on the performance of SSDs at their lowest possible performance levels.

    At their lowest possible performance levels are they still faster than the 300GB Raptor?

    It's too bad Windows and applications don't let you select where all the data that needs to be updated and saved to is stored. If that was an option a SSD could be used to only load data (EXE files and support files) and a HDD could be used to store files that are updated frequently, like a web browser for example, their constantly caching files, from the sound of this article that would kill the performance of a SSD in no time.

    Great article, I'll stick to HDDs for now.

    So even with the TRIM command, when working with large files, say, in photoshop and saving multiple layers, the performance will stil drop off? Reply

    I bought a Vertex 120GB and it is NOT working on my Nvidia chipsets motherboard. Anyone met the same problem? I tried intel chipsets motherboard and seems ok.
    I used HDtach to test the read/write performance 4 days ago, wow, it was amazing. 160MB/s in write. But today I felt it slower and used HDtach to test again, it downs to single digit MB per second. Can I recover it or I need to return it?

    Based on the results and price, I would say that the OCZ Vertex deserves a Editor's choice of some sort (Gold, Silver)... Reply
