Summary: Bought the NSA221 and added two 2TB WD SATA drives, which took about 10 minutes to drop into the two bays and get the unit up and running. I have about 40GB of music, 280GB of fairly large-file videos and 10GB of family photos, all set up for public sharing in separate folders mapped to an iMac desktop and a Linux laptop, and I bought the extra capacity for future use. Some notes: 1.
Summary: I've purchased this unit so that movies, TV recording and music can be accessed when my PC is off. I have a desktop PC with 900W power supply so just to stream music or movie; it really isn't all that economical. Initially, I setup this NAS with two 500GB SATAII HDD under RAID 0 since that usually gives the fastest data access speed both read and write. Both HDD were 7200RPM version with 16MB disk cache and during file transfer to NAS, it was averaging about 11 MB@1sec.
Summary: NSA221 is stable with good GUI and working apps, however data transfers are slow. At less than 12MB/s via ethernet it's probably one of the slowest on the market. NAS works well for streaming however backups or initial transfers are a struggle. On top of it USB transfers are about 1/3 of the ethernet speed so forget about transferring data quicker out-of-band. One of features I like is ability to mount and share DVD drive connected to the USB port.
Summary: I will amend this review later if I'm able to fix the speed issue I'm having. I have a gigabit router and all my cabling supports gigabit speeds however when I try to copy files to the device over LAN I'm getting speeds under 2 MB/s - that's unacceptable. I've had this issue on two seperate computers, both of which have Gigabit LAN and show they are connected at 1000 Mb/s.
Excerpt: При закачке новых данных - фото, видео - отображение их как на медиа-сервере появляется спустя часа два, при этом медиа-сервер должен всё это время работать, чтобы ОС нашла новые файлы и опубликовала их. Так и не понял, как можно ускорить процесс обнаружения новых файлов внутри устройства. Кнопка Обновить базу на Web-странице управления - не помогает, а просто запускает процесс обновления и тогда все ранее найденные файлы пропадают и надо снова ждать.
