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.

    Good and informative article.

    Regarding the shill tshen83 who claims that Anandtech cost the drive manufacturers millions of dollars in sales.

    If that is true, Anandtech has saved customers millions of dollars.

    Anandtech should care more about their readers losses than drive manufacturer losses. If Anandtech was a site for drive manufacturers and their shills we wouldn't be reading it.

    To me, if the SSD drive manufacturers lose money, it's their own fault for building crap that has higher write latencies than old fashioned drives with metal discs spinning at 7200RPM or slower. Not anandtech's.

    I can get higher sequential reads and writes by using RAID on old fashioned drives. It is much harder to get lower latency. So Anandtech did the right thing for OCZ.

    Lastly, there might be a way of making your windows machine stutter less even with a crap SSD. Note: I haven't tested the actual effect on an SSD because I don't have an SSD.

    Basically by default when Windows accesses a file on NTFS, it will WRITE to the directory the time of the access. Yep, it writes when it opens files and directories (which are just special files). That might explain the stuttering people see. For a lot of things, Windows has to open files.

    Warning! There are reasons why some people or programs would want to know the last access time of files. Me and my programs don't (and I doubt most people would).

    If you are sure that's true for you (or are willing to take the risk) set NtfsDisableLastAccessUpdate=1 as per:">

    Brilliant article and very informative on these emerging technology. I wont be buying one anytime soon @ their prices, but good to know we'll FINALLY be replacing convential HDD which are the one component that have been pretty much the same since as far back as i can remember

    "SSDs have +5 armor immunity to random access latency"

    rofl that's the best analogy i've seen on a hardware review site. is every comp geek a RPG geek @ heart?

    Great article. Realy made me understand what I need to look at before making the plunge. Mistakes and all, my compliments. As for value between the now seemingly drastically improved Vertex vs the X25-M, I compared prices between the two and per Gb, the Intell product for say an 80 Gb drive is Can $5.86/Gb, while the OCZ 60 Gb SSD is Can $6.81/Gb. Now that we are no longer comparing apples and oranges, I think we need to point out that the Intel product is not only faster and maintains it's performance edge better, but it is cheaper per Gb. At least in Canada. I have many OCZ products and I love the company and it's customer support. I can only hope that they will make their SSDs more competitive in the near future, because most consumers will pay the extra 70 bucks and go with the X25 when they pay attention to the numbers, both performance and price.

    I could forsee a whole host of issues with encrypting SSD drives, not the least of which is essentially making the drive completely "used" outside of the drive slack space - which would be a temporary reprieve for the reasons discussed in this article. However, I could also see potential performance and lifetime issues since modern encryption uses streaming ciphers (e.g. an entire encrypted block - which may or may not conform to the physical block size will be changed for even one bit change within the block itself). Has anyone looked at the resultant effect on performance due to using encryption - it would be good to compare say Bitlocker, PGP, Checkpoint, and an open source encryption solution (Crypt or something like that?). This could actually become a real driver for moving to on-drive encryption where it would have the opportunity to optimize the encrpytion for the pro/cons of the SSD architecture. Reply

    Great article! I respect that OCZ made the necessary changes to make this drive work. I'd rather take a slightly slower drive if it meant consistent performance.

    If my hard drive started to stutter I'd flip out! I'm glad that they took the feedback and instead of selling faulty drives, that would ultimately hurt their brand, they decided to go back to the drawing board and iron out the kinks. I'm not expecting them to compare to Intel's 25-M per price or performance. They don't have nearly the cash or manufacturing capacity to compete with Intel but they do have that small business feel with receiving feedback and making improvements, which is important to customers.

    Lets hope they continue to utilize that aspect of their business and further improve on their products and bring us some reliable SSD's in the future.

    although, I have some issues which I have put in an e-mail sent to Anand; can't wait for you response. Reply

    Instead of making me dinner can you send me that test system instead??? Please!!! Reply

    I was wondering what controller the OCZ solid Series is based on??? Will I experience hiccups with that drive or not? Is the point of my question. Reply
