Our final series of tests are what you might call more "crude measurements" in that we simply fired up our trusty stop-watch and measured the time it took to complete a copy and paste command of a single large file or a bunch of large files from one storage volume in our test system to another.
** Please note that we utilized a Fusion-io ioDrive card as our source drive in some of the following tests, to read files from or copy files to, for our read and write measurements of all reference products and the ioXtreme cards. This affords us the luxury of much higher available bandwidth from the source or target drive, such that it would not be the limiting factor in a given test condition. We've also included some measurements with a standard WD Raptor 150GB hard drive as our source or target drive, to offer a more practical usage model and benchmark measurement.

Here the ioXtreme drives offer a sizable performance gain over a standard SSD but actually trade victories with OCZ's Z-Drive. The ioXtremes offering slightly faster read performance, while the Z-Drive took the write file transfer test by a few seconds. Interestingly, in RAID 0, though write performance was significantly improved, read performance fell back slightly with the ioXtreme drives in this test. Next, we performed the same test with the ioXtreme drives and a WD Raptor as the source or target drive for read/write transfers.
Here the field was quickly equalized, with all product tested being held back by the slower spinning hard drive, when either reading from or writing to it. However, the Z-Drive managed to edge out the ioXtreme product in this test, with the exception of the ioXtreme's RAID 0 performance which offered an advantage of about 10% or so.
Though still a little on the large side, we think our custom multi-file transfer test is a bit more representative of a day to day workload that and end user may put upon the product. Here we've transferred the same 3.5GB of data to and from the drives we tested, only this time it was comprised of a bunch of 100MB+ sized files (video files to be specific). In this test, the ioXtreme drives still can't catch the Z-Drive with writes, unless they are striped together in RAID 0. For read performance, the ioXtreme single card setups beat all competitors with a couple of seconds to spare versus the Z-Drive.
