Sandisk Extreme 64GB - Slower write speeds after system format

I’m a huge fan of Western Digital and WAS a fan of SanDisk but after owning this stick it will be my last SanDisk purchase.

I work in I.T. and have formatted hundreds of drives. It’s a very common thing and i didn’t think twice about formatting this stick. The effort i’ve put in to get this back to a decent state is stupid, and it’s just not possible, the write speeds are less than that of a standard USB 2.0 stick. I’ve even tried aligning the partitions as previous posts have suggested but no dice.

For anyone who finds this thread in the future, make sure this is your last SanDisk purchase, they don’t deserve your money.
