The extra over-provisioning to compensate for the lower PE cycles is quite a bit too. A marketed 120GB drive right now formats to just 107GB. Right off the bat you lose 13GB.
Good point. Without SATA3, the newer drive isn't of much use. I suppose my main point was, the performance can be had with 25nm, it's just a matter of time before we get there. Any 25nm drives you can currently buy have terrible performance compared to the better 34nm drives, but that will be changing down the road.
Also, while overprovisioning does take away from usable drive space, the space should be cheaper in the end from the cheaper NAND. In other words, you may only get 107GB on a 120GB drive, but the savings from using 25nm will likely mean price drops to where that 120GB drive costs the same as a 90GB 34nm drive would have.
I'm just saying, there is hope for 25nm in the future. It sucks right now, but down the road, it'll be better than anything we have available in 34nm right now.Edited by SgtSpike - 2/25/11 at 11:24am
