Hi, I need some advice to choose between Revodrive 3 X2 and RAID 0. For scientific calculations I read/write and sort large (10GB+) files. We had multiple clusters at the university, but the disk speeds are serious bottlenecks (once I had a chance to test my stuffs on our storage rack natively (a base 4 core nehalem server with 24xHDD RAID and 96 GB) and despite the 0.5x cpu power (same cpu, only dual) it was much faster than the 2x4 core servers I use every day (4xHDD in RAID and 96GB), because of the read and write speeds (the computational part was of course slower)). I have a base Quad Mac Pro 2010 which is a very good machine indeed. I decided to change my previous ssd (Intel x25-m G2 120 GB) and put it into my Thinkpad X60 (only sata I so the max. 100 MB/sec write speed is not a big problem). To replace it I am thinking about to get a pci-ex Revodrive 3 X2 240 GB to store my work data (~180 GB) and get a 128 GB Crucial M4 as a boot drive (plan A ). I read about the Revodrive's booting problems but I do not need it for booting, only as a very fast storage (for backup/videos/music I use the supplied WD Black). Can anybody confirm that the Revodrive 3 is working in Mac Os X as a storage drive? Right now I use Snow Leo but in the near future I will change to Lion (new OpenCL The plan B is buying 2xCrucial M4 256 GB and run them in RAID 0 as a boot drive. But since the Mac Pro has only sata II ports the achievable maximal write and read speeds are 500-525/420 MBs against the Revodrive's 900/1000 MBs . I really do not want to use HDD-s anymore only storing videos/music/backup (I used an 4200rpm drive for four years in my old toshiba laptop.... )) With a fast SSD solution I can finally use my Mac as a working machine (with the revo and a 6-core cpu it would be better for my needs as the octo at the uni ) Thank you!
