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.

If you get Newegg's specials, one of the codes is for the 30GB for $103 with a $20MIR, so $83 with shipping if the rebate comes through. At the size I would want (~120) the Super Talent undercuts the OCZ slightly.Does anyone know if you can install the firmware of one maker to another maker's SSD? For example, assuming both the Ultradrive ME and the Vertex use the same Indilinx controller, and say Super Talent chose to release it with the firmware which optimizes for higher sequential speeds, would the user be able to choose the firmware which optimizes for less latency?

Ah, no editing?!A-Data's "300 plus" SSD also uses the Indilinx controller.

"The Anatomy of a SSD" should instead read: "The Anatomy of an SSD"Flunk - Wednesday, March 18, 2009 - link
Yes, because S is a vowel...abudd - Wednesday, March 18, 2009 - link
Assuming SSD = "es-es-dee" then "an SSD" is right. If it *sounds* like a vowel, use "an".JarredWalton - Wednesday, March 18, 2009 - link
Yes, *but* SSD could also be read as "Solid State Drive" instead of "ess ess dee", in which case you would say "a SSD". I tend to read it as "ess ess dee", but Anand thinks of those letters as "Solid State Drive".Potato, potato, tomato, tomato... let's call the whole thing off!

When reading acronyms you're supposed to think of them as the letters, i.e. when you see RAM, you think "ram" straight off not Random Access Memory. When you see "IBM" you think "eye bee emm" not International Business Machines etc etc. It would take ages to read an article if you had to stop and think out all the full wording of acronyms as you're reading them.I'm going with the correction of "Anatomy of an SSD". Correct English fullstop.

By your comment, you suggest two different things, and that's really okay. That was my point: when you see "RAM" you probably thing "ram" as in the animal... not "Are A Em". You say "a RAM stick" not "an RAM stick". I'd guess most people think of SATA as "Ess A Tee A", but if you talk to most computer techs that are in the know, it's "say-te" so you would say "a SATA drive".And you know, I'm sure plenty of people will agree with the correct way of saying SATA, and that's perfectly okay. English really is a very flexible thing - particularly in the tech world - and rarely is there an "always right" way of saying things. If Anand wants to say "a SSD" and others want to say "an SSD", I'm not going to try to declare one group or the other correct. They both are, depending on your viewpoint.

HAHAHA. What a tool. I love it when people critique grammar.....and get it wrong.
