Thanks, I might just wait for Samsung to release a Mac/Linux utility. I have bootcamp on my iMac but not on my Macbook
Also do you know by chance if I need the firmware if I'm running Trim? I read the firmware only fixes/enhances the 'dirty write' issue.
Thanks again!
can we gets some screenshots of the 128gb 840 pro's speeds? I want something to compare mine with. tx

Isn't that a lot slower than its supposed to be?
Write Speed is definitely lower than I was expecting, but Read Speed isn't too bad. I'm curious if I have something configured wrong or if it's 'cause it's not an 840 Pro?
Speed is correct. Just read the specs of the drive: http://www.newegg.com/Product/Product.aspx?Item=N82E16820147188&Tpk=samsung 840 120

The difference in write speed is insane for the different capacity. You have the 840 non pro 120GB. I have the 840 non pro 250GB. We both have the same laptop with the same 16GB upgraded RAM. I have FileVault turned on so I took a 50MB/s write speed decrease.

That's pretty impressive speedup!
Hi folks,
I have a 2010 MacBook 13" Intel Core 2 duo and my read speeds doubled but it's only 110 mb/s instead of these 400+ speeds others are posting. Is that because my old mbp hardware? Loads/saves/startup/shutdown etc.. are so much faster than it used to be but my disk speed results are pathetic compared to some of these!
That is pretty impressive Read speeds!
There have been some issues with SATA-III SSD drives installed in the optical bay attributed to "noise" in the cable or interface. These were on 2011 MacBook Pro machines, I don't know if they have resolved this with the 2012 generation.
Some posters have reported some success by adding additional shielding to the cable. Most posters here are only adding a SSD to the existing Hard Disk, and have circumvented the issue by installing the high speed SSD in the original disk location, and putting the much slower Hard Disk in the optical bay area with a mounting tray (optibay). OWC recommends putting only SATA-II SSDs in the optibay for best results (some SATA-III SS drives can be programmed to only run at SATA-II speeds).
Although Apple may be aware of the SATA-III issue with the optical interface, they probably don't have a lot of urgency to fix the issue since all models only ship with really slow optical drives in that location.
Good luck with your project ... RAID-0 SSD in the MBPro would be really nice!

Installed the 840 pro 256GB in wife's mid 2009 MPB.
Getting 204mb/sec writes, 256mb/sec reads, consistent with the interface on this machine.
I am pissed that there is no firmware upgrade tool for mac. That is crap and I wouldn't have bought it had I known that in advance. Firmware updates are important for SSD and for them not to support mac computers, well we should not support them.
So although this works fine thus far, I would advise others to look elsewhere to a company that actually supports mac.
Hi,
i installed an 840 Pro 256Gb in my Early 2011 MBP 17" (2.3GhZ Core i7, 16Gb RAM) and get these results - quite lame compared to what i see in this thread.
Profilers states full 6GB link speed - can anyone bring me or better the SSD up to speed? Did i miss something while installing? Firmware is not the latest, the one with the 3 in the revision number...
