I bought the JetDrive Lite for continuous use in my Macbook, I mean quite a large photo library can outsource it. The rate is as stated and realistic. Lightroom can be very good to work with it, all copy operations or conversions or so go very fix. A bit of bother me. that the edge is black. When the silver was, it would be perfect. However, one should not be too strong jerk on the map, otherwise it could be that they lose contact. Happens in normal operation but hardly ever.
Thus the card is not so power-intensive and strikes the battery, I have downloaded and installed from Transcend a toolbox for JetDrive products. The casts every time before the standby mode (when closing) of the card and mounts it again when you open. This saves a lot of electricity and works perfectly, you can tell them absolutely nothing.
