You have a link? I can't seem to find it (not ruling out that I am blind).
Thanks!
Delivery Update -
The AC3200 will be delayed by about a month to market. After a long beta period we decided to tweak the hardware and a few other items. I will have an update in a couple of weeks as to a firm US release schedule at retail.
Bad News
Source / Scroll down so fast :
That's nothing new. They've been saying for months that they didn't expect USB performance on the AC3200 to be at the same level as the AC87U.
but why ,
so i should understand that it will be worse than AC68U because when i tested AC87U USB , it gave me the same speed as AC68U
we are supposed to be moving foreword not backward
I get much better performance from the AC87 (65 MB/s, and I've seen an early alpha build that was able to break 70 MB/s) than the AC68 (50-55 MB/s), so your bottleneck was probably your disk. The 200 MHz CPU clock difference alone would make a difference.
I suspect the AC3200 will be somewhere between both. Asus always marketed the AC87 as being the flagship - the AC3200 isn't meant to replace it, but to stand between the AC68 and the AC87.

It's (AC87) capable of more than that.
I have a 128GB USB 3.0 memory stick on it. (Silicon Power Blaze B30) Specs for the memory stick are 200mbyte/sec read. (I get the full 200mbyte/sec on a Mac Mini, so what we see below is I presume the CPU limitation.)
Don't waste your money on, say, WD Black - the CPU isn't fast enough to max it out. Just about any other hard drive out there, though, you will get close to the max rate. It will max out on VERY fast USB 3.0 sticks.

What's your CPU frequency?
Thats stock clock, try 1200 or 1400 you will get 10-15mb/s more.
im still so torn between upgrading to the 87U or waiting for 3200.
