On paper, this is interesting. But in practice, it does nothing except frustration. Not wanting to make a video server for HD, I wanted to store my digital photos. Alas, in use, now that the 2 TB drive is filled to 40%, I am tormented by its slowness. 10/100/1000 Ethernet, his manager does not follow. Well, store a .doc or .pdf file, it passes. Although it must give him time to peruse its FAT before it commits the backup. But for the photographer that I am, it turns into a nightmare when you want to empty, for example, the SD card to 8GB. I work with SDHC 10MB / sec cards ... but in use, at full speed, transfer rate does not exceed 2 MB / sec. It is even closer to 1.6 to 1,7Mo / sec. As each picture weighs from 10 to 12 MB in jpg and 25 raw, so you have to a minimum 30 seconds per photo. Either good 2 hours or more, to transfer the card. And openings / closures files also seem very long ... The in-house storage takes him only a few minutes to 20 or 30 seconds Lo. And my last card 32GB Extreme Pro allows 70 to 80 MB a second ... Finally, the disc is in a proprietary format. This means that in case of an accident on the controller, no need to remove the disc and put it in a standard pc. It will not be recognized. Say I stored 40.000 shots !!! I've read reviews where the guy says apvoir lost 10 years of photos without recourse Arghhhh ... ... The solution is to change it to a more powerful NAS, more compatible, also has a USB 3.0 port (the WD failed) for quick local transfers, but especially a RAID controller to do RAID 1 or better RAID 01. Either copy or mirror copy mirror + aggregation (admittedly we go to 2 or 4 discs, but computer security is at this price).
