Does anyone here that is posting actually own a Revodrive?
Here we go again.. I bought my original Revodrive when they first came out. It had the green dot so was ok, just after the firmware issues which tarnished their name. A lot of people on here don't like them because they didn't sell well after initial batches had this firmware problem and this is how they got their reputation. However, there are many sheep in this field and only one or two shepherds that can speak from experience

You need to leave about 8GB asside unallocated so that the system can use this to regen the other blocks.
TRIM is NOT an issue - my original Revodrive is 3 years old and still benches at exactly the same speed.
As usual on here, it is people's opinion that do not or never have actually owned this product. I am on my second Revodrive2 now and have had no problems whatsoever, only upgrading to a faster one. Quite simply this is the most amazing drive I have ever owned and I have been building high-end PC's since they began with component selectable 486's. It doesn't use SATA connections, it doesn't require any high-end RAID controller, you plug it in and it works. The higher end Revo's read at 1.5GB/sec and write at 1.25GB/sec. Yes they are a bit special and yes they get mixed reactions, but it gets my goat up when the place is full of so-called experts that don't or have never owned one.
Just my 2p
