Yea, same here, except I gave OS X 180GB and 70GB to Win 8.1 Pro. I imported the BootCamp partition into a virtual machine and wiped it out. (Btw, you can still get the BootCamp partition back by using the utility, can’t you? If you wanted it back, that is)

Read speeds are about the same, but the writes have improved by 40MB/s. My 256GB SSD has 140GB free, so it’s got plenty of room, too. I’m probably going to re-install the BootCamp partition, though. (I love operating systems and tinkering with them. ha ha)

So you have it in a BootCamp configuration… I ended up getting rid of that, but wish I had same now as i could have tested. I originally had the 256GB MBA drive partitioned evenly for OSX/Win.

I want to say I remember them being approx. 100MB/s faster on reads and maybe 50 on the writes.

Like I said, I’ve been wondering about this partitioning SSDs and the possibility of performance degradation. I read an interesting post from one seemingly knowledgeable person who opined that SSDs do not handle data in a way that would reduce performance as a result of partitions being in place. That would be good news.

Who knows. What I do know is that I’ll wipe out the BootCamp partition in the next few days and we shall see what’s what. I also know that I won’t tolerate any type of significant performance drop on account of Windows being installed natively. I don’t want to be without Windows either, though, so I may just re-install in a virtual machine.

I’ll also do some tests as far as formatting to lower and lower sized partitions, so we can see if the size of the partitions matters. (it does on hard drives)

Thats a tough one and I wonder if yo partitioned it lower if performance might drop further, similar to lower capacity SSD performance??

The performance shouldnt drop because of the formatting, at least that hasnt occurred in our testing.

What were the original speeds?
