    Full Stop. 
     
    No. 
     
    The Read Striping may improve performance, but we still have the added overhead of reading from NTFS volumes.  And the performance profile for doing so.
     
    RAID 1 works at a block level, and it's able to split IO requests between the disks.  SO one disk could read the partition table information, while the second disk starts reading the actual file data. 
     
    This is a vast oversimplification of what happens, but a good illustration of what happens.
     
     
    So, while we may read from both disks, in parallel, there are a number of additional steps that we have to perform to do so. 
     
     
     
    To be blunt, the speed is never going to rival hardware RAID.   However, between with disk switching, and the reading blocks of the file and caching into memory. 
     
     
     
     
     
    That said, you should still see at least the native disk speeds, or a bit better. But this depends on what the disks are doing, specifically. 
     
     
     
     
    CrystalDiskInfo probably isn't going to get great stats because of how it tests the data.
     
    At best, enable pool file duplication, so that EVERYTHING is duplicated.  Make sure Read Striping is enabled, and then test.

    Mr Ethernet reacted to Christopher (Drashna) in SFTP-ing large movie files straight into a drive pool. Best practice?   
    I guess that would really depend on the client/server/service, and how it handles uploaded files. 
    However, it shouldn't be an issue, in most cases.
