This uses same software (generic 3rd party) as the SansDigital MN2L Nas. Very basic and tedious to navigate. Like the drives inside and if you need raid 1 (mirroring) which is why I got it, then this will do the job. Transfer speeds are acceptable for large files, I save video files, hence raid 1. This product is by far one of the lowest priced on the market (calculate price of just 2 500gb sata drives alone). I liked it so much I am now ordering my 4th unit. Installed in Windows home office network, mix of xp and vista machines (32bit and 64bit - all pc’s access shared device no problems). Gave it low ease of use score for the generically limited software (but once installed and shared, don’ need software any longer). Performance is acceptable for storage, do not use it for heavy access. Value makes me very satisfied and will buy more as my storage needs grow.
