Wiping an SSD

post #1 of 10
Thread Starter 
I just bought a 90gb Vertex 2 3.5" SSD to swap out my OS SSD, which is a Western Digital SilconEdge Blue 128gb SSD. I bought the Vertex 2 with the 20% off coupon and couldn't pass it up, and since I was running a bit low on space with all my games...

Anyway, I got the drive last night, installed Windows 7, drivers etc., then hooked up my WD SSD, and formated the drive in Windows. I then installed the Steam folder on my WD SSD and began downloading games to it. I only plan to use that SSD for game storage, but I am wondering, should I have wiped the SSD clean before installing anything on it? I have heard that a format doesn't exactly "cut it" for SSD's...

Any input?

BTW, the WD SSD was always TRIM enables, always fast, and never missed a beat. It also was never filled over 75%, FWIW...

WD SSD? As in 'Western Digital'? *edit* interesting, hadn't seen the WD ones yet.

Only do quick formats with SSD drives, NEVER do a full/low-level format. Garbage collection and TRIM will take care of the garbage files.

You can do full formats on SSDs. This is what secure erase does... write 0s to everything to restore original performance. It requires just one write cycle for each bit.


Garbage collection and TRIM can sometimes get "stuck".

You can do a full format but that's additional wear that can be dodged and provides very little benefit.

I've never had a problem with GC cleaning up the mess. Can you describe what you mean by GC/Trim getting 'stuck'?

TRIM is merely a command given by Windows so I can understand a software hiccup here but GC is run via the SSD controller, I'd be a bit worried if it gets 'stuck'.

Just to give an example, I ran one of my 64GB C300's for a few months and nearly filled it to the brim (over 50GB stored). I quick formatted it before building my current array and I've seen the same performance from day 1 to the present.

So moral of the story is that I am okay with how I formatted the drive?

A full format will cost just the one write cycle.

I have seen cases where SSDs perform terribly out of the box even after a fresh install. A secure erase and reinstall fixes the issue. I have seen this a few times and it seems that a secure erase is the way to resolve it.

If it's already been done then you're fine, nothing you can do and the additional wear is minimal.

One write cycle across each bit.

I'm still curious on how you know that GC/Trim gets 'stuck'. Without Trim, GC will only operate when the drive is idle so obviously my method will require some idle time for the drive to clean itself up (even when Win7 is freshly installed).

It's not uncommon to see poor performance on initial installs considering the amount of variables in play.

Given their less than stellar reputation, I was VERY hesitant. But after coupon, shipping, tax, and rebate, the drive comes to about $100. So it's not a huge sum of money. And given that the Sandforce 1200 controller is generally well recieved, and it's nearing the EOL... it should be as good as it's going to be...
