Disable RAISE for more space on SandForce SSDs?

So I have a G.Skill Phoenix 3 120GB SSD (http://gskill.com/products.php?index=537) and they've released a new one that seems to be identical except that it's 128GB (http://gskill.com/products.php?index=581). I think it's most likely due to G.Skill disabling RAISE to get that extra 8GB NAND die back. Does anyone know if it's possible to convert my 120GB drive into a 128GB one? I think that would be pretty awesome. :biggrin:

That wouldn't be a good idea. SSD's need spare area to keep performing at their best. If you fill up that 128GB drive, the performance is going to be utterly horrid. In fact, if you take AnandTech's advice, your 120GB SSD shouldn't use more than 96GB of its space to keep performance constantly near its optimal (its a good performance / sacrifice level).

If you really need that extra 8GB, you should seriously consider getting a larger SSD.

The amount of OP is the the same. RAISE improves ECC.

You could always see if you can flash your drive to the new one's firmware, but I wouldn't want to risk it, for my PC's drive 🙂.

As cerb rightly says this could be possible with newer firmware. But I do not think by doing so on this 120GB model you will still be able to protect your warranty. Moreover, If you want to do it the hard way, you will still not be able to change the OP. I have critical data stored my SSD and do not have any other medium to get this transferred, else I believe I would have given a thought like you 😉
 
A change like that has to be done by the manufacture when programing the drive. There are all kinds of limts too, like some drives manufactured with certain flash can't be reprogrammed, others can. It would be a PR nightmare if any company did it.
