In the Intenso housing, a hard drive from Western Digital WD is in my case, built 500 BEVT, preformatted in FAT 32, with a real storage volume of 465 GB.
Have connected to my PC and checked with the freeware programs, CrystalDiskMark, CrystalDiskInfo, the speed, the data read Info Intenso Memory Station, for possible errors checked, etc., see also pictures here at Amazon.
Another practical feature is the the Intenso Memory Station a spin down function (standby), and after a few minutes if there is no access to the hard drive, go into idle mode.
The speed is high enough in order to save even HD footage, you can even a recorded HD Recording watch and simultaneously save a new HD recording on the hard disk.
The green indicator LED on Intenso housing, permanently lit and flashes when access done to disk, is decent and not too intrusive.
Works for me on the satellite receiver as the recording media very well, is fast enough, so I for Intenso Memory Station 500GB, for 5 star.
