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.

    Depends on how smart the controller is? Shuffling around the data now and again in the background would make sense. Reply

    @AT
    This is why i come to AT to read up on the developments.

    @OCZ
    Well played :0)

    The ruler of the roost are the Intels however I will be able to afford one of those when there are cows enjoying themselfs by dancing on the moon. My next upgrade will be a Vertex - not only bc its Valu for money but equally much bc. OCZ obviously takes care of thier customers and listens to reason.

    This is the kind of article that makes me come back here. Reply

    OCZ, you should listen to Uncle Anand. ;) Hopefully Mr. Petersen understands that it's tough love.

    And the final product seems perfectly cool -- great performance at a better price than Intel. It's the first SSD I'd be able to reasonably consider.

    Thx for this article Anand, I have been in a hotly contested debate over OCZ vs Samsung with my "Asperger Enhanced" nemisis/close friend...
    (In all fairness, I should mention I use the BiPolar SSE instruction set myself)

    He was only looking at Samsung, I said he should look into what OCZ has now.

    His reply was "I don't know them, and don't want to be disapointed"
    (Long story behind that...He's from the Server/Workstain/HPC crowd, I am from the hardcore OC/Gamer/Desktop group, so he is not familiar with OCZ)

    Looks like the Samsung (And alot of others) has "Issues" with performance degrading over time that are somewhat solved by Intel and OCZ (Plus maybe a few other companies that use the Rev B JMicron controller on there low cost SSD's)

    I agree the OCZ Vertex offers the best bang for low buck SSD today, and I am tempted to grab one. But a year from now, anyone that bought a current gen MLC SSD will be saying "I coulda had a V-8" if that TRIM technology does what it promises!!!

    As people continue to try and push the envelope of storage performance in a variety of ways, and as 6gbps SATA becomes available, the performance of SSD's will only go up.

    As always, I wanted to say thanks for the great article and keep them coming. It's the only way the rest of us can keep pace with what's happening out there in the world of performance storage.

    Is there any benefit in using 2 SSD's in a Raid 0 configuration?
    And: any differences between motherboard Intel Raid vs. a Raid controller card from Areca, for example. Also: can the "Trim" command work while in Raid mode? Probably not, I'm guessing...

    Raid0 is really the holy grail for SSD's. The low risk of failure of SSD's which normally makes Raid0 with typical mechanical HD's more dangerous is very appealing. My personal storage-size goal is ~120-160gigs. Once they reach that size for under $300 I think I'm going to jump in. But I'm more likely to grab 2 60's or 2 80's and Raid0 them than get a single large SSD. The added performance will outweigh the higher power draw of 2 drives, and should make them extremely competitive with Intel's offerings (or whatever holds the crown at the time).

    I figure it will be about a year or so until the prices are in that range, as 2 60gig Vertex drives will currently run you about $400 after rebate.

    I can't wait to jump on that upgrade and will then put my current 250gig mechanical drive as the storage drive (I don't use a ton of space in general as I have a 320gig external backup).

    The problem with doing that is if you want to move your drives to another system they won't work, so upgrading is a pain. You could image them I guess, but plugging one drive in is much simpler. I had an older XP install that made it through 3-4 different systems.

    I would also question real world results, if you're going at 250MB/s or 500MB/s its not even going to be noticeable unless you are doing some massive video editing or some other huge file operations, and as Anand says, SSDs don't fill this role right now as they are super expensive per GB. So if you really are editing video a lot, you are going to need a hell of a lot more space than SSDs can offer you.

    RAID is a universal standard so if you take two RAID0 drives out and move them to another computer with a RAID controller, it SHOULD just work if the original RAID was doing it correctly. Reply
