It's because your mini only runs at sata2 speeds. The 840 will hit those screaming numbers only on sata3.
what is my best choice what should i do
thank you all
i have also macbook pro early 2011 i want to upgrade it also so what if
i replace the ssd from the mac mini and buy another one for low performance up to 250 MB/s what would be the choice
Crucial m500s seem to be pretty cheap these days. Really any brand will be plenty fast for SATAII. Check the online reviews and pick one you like.

I just put an 840 EVO in my late 2008 Aluminum Macbook and am getting similar speeds to the OP, I'm going to be getting a new drive for my wife's older Mac soon and will probably get her an M500.

For the 2011 MB, with SATA 6Gb/s, get the Samsung 840 Pro or the new follow up of the OZC Vector (don't know the name).
I have the 830 in my 2010 mini. I'm getting the same speeds you are with the 840. See if you can find a deal on last year's model and save a little cash!
You will get 490-500 MB/s on Early 2011 MBP, this is the practical cap of the SATA3 connector on that specific batch of MBPs. The 840 EVO is a very close match to this speed, so yes put it in your MBP and then buy something much lesser for the Mini.
Thanks for sharing. FYI my Mini 2009 with a Western Digital Black 750gb running at 7200rpm returns about 110 on Blackmagic, so the SSD is 2 to 2.5 times as fast.
