This is the MZ-75E500RW model which is the starter kit. Not only is this more than £10 cheaper than the MZ-75E500B/EU model priced at £149.99 but it also includes a sata to usb 3.0 cable worth £7.49. There's also a small tray base mount so can be used as an external SSD drive! (although speeds will be limited to the usb 3 interface). This model has been discontinued by most retailers.
