This 4GB Memory Stick Pro Duo on VolumeRate.com has proven to be quite effective and cost efficient!  The lack of MagicGate technology should be no concern because it has so little uses.  This product features 4GB (3876 MB) of capacity or close to that; unlike those fake ones, this one does have 4GB.  I personally used it as PSP or camera memory, and so far it has been 100% effective and no failure reported.  However, in one case, the SONY-DSC-H2 Camera user reported that the transfering rate of this memory stick is 100X slower than usual.  I here to confirm that it may not be true as i've tested on different devices for transfering speed including downloading and uploading.  Compared with the Sony 4GB Magic Gate Memory Stick Pro Duo, the downloading speed is about 1/4 slower (which means if Sony Memory Stick = 6 min downloading, then this 4GB memory stick would take about 7 min 30 sec to complete).  However, the uploading speed is the same as Sony 4GB Memory Stick Pro Duo.  I personally recommend this product because it is cheap compared to the Branded ones, and it has almost the same functionality. 

Verdict 8.5/10
