Thumper_23 Posted May 2, 2013 Share Posted May 2, 2013 Hi guys, has anyone heard of having issues with Samsung 840 Pro SSDs in RAID 0 in the M18x r2 especially if you have the 680M SLI? Thanks Quote Link to comment Share on other sites More sharing options...
svl7 Posted May 2, 2013 Share Posted May 2, 2013 I don't see how the GPU can have any influence on the RAID setup... But I wish I had a 840 pro raid 'Only' running one in my desktop and it's already incredibly fast. Quote Link to comment Share on other sites More sharing options...
Guest Tomas Puzis Posted May 25, 2013 Share Posted May 25, 2013 You should be more specific, what kind of issues? I'm running this setup and everything is fine and dandy. Quote Link to comment Share on other sites More sharing options...
Allen George Posted May 26, 2013 Share Posted May 26, 2013 I can't see any way there could be a direct correlation here outside of a power draw problem, which unless you have a massive OC and OV on your CPU and GPUs, is pretty much out of the question.

vs3074 Posted May 28, 2013 Share Posted May 28, 2013 I was told dell doesn't offer Samsung 840pro raid and 680m sli due to incompatibility issues, not 100% where they arise from. It has to be something related to firmware dell puts on the ssd's. Quote Link to comment Share on other sites More sharing options...
Hybrys Posted June 8, 2013 Share Posted June 8, 2013 There have been a few issues reported with this setup, but some people have gotten it to work.. My recommendation would be to buy a pair locally, test them out, and return them if they're odd. Apparently it was only a few firmwares that had the issue, including the one the Dell 840 Pros are locked to. Quote Link to comment Share on other sites More sharing options...
scaesar Posted June 14, 2013 Share Posted June 14, 2013 I heard having SSD's in a raid 0 configuration doesn't give you that much of a performance upgrade. Quote Link to comment Share on other sites More sharing options...
littleone562 Posted June 18, 2013 Share Posted June 18, 2013 Try disabling agressive LPM in unlocked bios, and also enabling hotplugging. These disable power savings feature of the ssds. Quote Link to comment Share on other sites More sharing options...
ArtemD Posted August 16, 2013 Share Posted August 16, 2013 The issue with SSDs in raid comes down to actually maxing out the SATA speeds. Since most newer laptops including M18x's support SATA 3 which has a maximum theoretical transfer rate of 6Gb/s = 750MB/s, and RAID 0 promises up two 2x the performance of a single drive(if 2 drives are used), there is definitely a potential for 2 speedy drives(500 MB/s+ read/write) speeds, to actually saturate the connection and hit a ceiling. Now of course this is all theoretical. Real world mileage may vary and your results will probably be a bit different. Quote Link to comment Share on other sites More sharing options...
Yeti575 Posted August 18, 2013 Share Posted August 18, 2013 Unless mistaken this is a performance thing only (?). RAID-0 trades reliability for speed. i.e. throughput speed is roughly doubled and fault tolerance is halved. If either drive in a RAID-0 array fails you loose ALL the data. RAID-0 is great for temporary storage of scratch data and also for the OS (assuming it's well backed up) but beyond that I would not use striped volumes for long term data storage.
