Hello.. I was really hoping somebody could help me out with this, as I'm pretty much starting to lose hope..I've attached as many relative screenshots as possible, to make it easier to quickly see what's going on.I've gotinstalled inside my MacBook Pro..(SuperDrive Bay), using an OWC Data-Doubler..I've got these drives configured using Disk Utility, into a RAID-0 striped configuration..550MB/s520MB/sSo "theoretically", I should be achieving approximately close to double these speeds (since that's the basis behind RAID-0 configurations).. Both in the hard-drive bay, as well as in the Optical Bay (confirmed in pictures)..I'm getting, yet.. to the point that the RAID-0 software configuration is not even achieving *near* the "Write" Speed of even one of these drives.. let alone 2 of these drives in RAID-0..I've tried contacting Samsung directly regarding this issue, but since they don't exactly get along with Apple, and even more-so, dislike anything that has to do with "RAID" configurations, I was left with practically no help on that end..I've tried contacting Apple, who said that I'm pretty much on my own, in terms of support, sincedon't exactly get along with Samsung either.. and don't provide much of any support whatsoever, when it comes to third-party, hardware components that are not upgraded directly through Apple themselves.. (aka no support for user-end personal upgrades)Both of these drives aredirectly out-of-the-box, shipped from Amazon , as "new, un-opened" items..The rest I will go on w/bullet-points, for easier reading purposes:-Both SSD's individually formatted GUID-then created into RAID-0, striped configuration-16K block size .. the minimum selection available (I work with many small files)-all done using OSX Recovery Assistant + OSX Mavericks full installer, loaded onto externally connected hard-drive-both showing up as "Online" in Disk Utility-"Repair Disk" and "Repair Permissions" ran on every single thing possible within OSX Recovery Assistant's "Disk Utility".. everything showing as perfect-install of OSX Mavericks 10.9.5 completed without any issues whatsoever-*Purchased*, fully-upgraded, installed properly-TRIM Enabler showing 100% clear, working "status"-TRIM Enabler settings all set via direct, specific instructions provided by Samsung support-Basic Hardware Test (quick) = No Problems Found-Extended Hardware Test (long) = No Problems Found-"Repair Disk" and "Repair Permissions" ran on every single thing possible .. everything showing as perfect-both RAID slices showing as "green" and "Online"-Manually reset-Manually reset-Proving terribly slow performance (not anywhere near the copy+paste speed of even 1 of the SSD's, let alone 2 of them, exact same model and size, configured RAID-0)I apologize in advance if there's a lot of pictures to go through, however, I know how much of a pain in the ass it can be to troubleshoot these sort of problems, let alone, try to help somebody else troubleshoot these problems while not physically being there in person.. I tried to provide thetroubleshooting steps I've taken thus far, as to hopefully make this thread as fruitful as possible, and eliminate any unnecessary steps that have already been taken..I've tried re-formatting and re-installing OSX Mavericks 10.9.5 several times now, hoping that maybe one of them would allow the RAID formation to work as it should, yet none so far have proven successful..If you have any time to look through and read this thread, I can't tell you how appreciative I'd be for your help and any advice possible that you can give me.. I do large amounts of audio processing, producing, along with many other taxing system processes, so I'd really like to get this RAID-0 configuration working as it should be..Please do not waste your time by bashing RAID-0 or writing an unhelpful, opinionated comment that does not move this process forward.. I understand the risks of RAID-0, I run, as well as having an Apple Time Capsule running in full-force, all day long.. My data is well backed-up, and I understand the risks.If anybody has dealt with this sort of issue before, please, give me any advice that you can.. I tried to put in the most effort possible with uploading and embedding all of these photos, as to not waste your time and to hopefully make this troubleshooting process as smooth as possibleThank you all so much in advance!
