Don sarrafa software, kuna buƙatar QNAP External Raid Manager, wanda yake samuwa ga macOS da Windows duka. Anan, ana samun tsarin sarrafa fayafai gabaɗaya, inda zaku iya ganin ƙarfinsu, matsayi, hanyar haɗin gwiwa, kuma ta wannan kayan aikin, ana saita hanyar amfani. Komai a bayyane yake, mai hankali kuma baya buƙatar ilimin da yawa game da batun. Kawai zaɓi nau'in haɗin faifai, zaɓi diski ɗaya don wannan haɗin kuma yi amfani da saitunan. QNAP TR-004 yana shirya faifai, sannan kawai tsara su (ta hanyar kayan aikin tsarin) kuma kun gama.

Yanayin Mutum ɗaya ne mai sauqi qwarai, ajiya a cikin na'urar kawai yayi daidai da iya aiki da adadin fayafai da aka yi amfani da su. Lokacin da ka shigar da HDD 4-terabyte guda huɗu, zaku sami 2 × 0 TB na sararin ajiya. Yanayin JBOD yana ƙirƙirar babban ma'adana ɗaya daga jimlar faifan faifai, wanda ake rubuta bayanai a hankali, ba tare da wani nau'i na tsaro ba. Muna ba da shawarar wannan yanayin kawai idan an yi wa jigon gabaɗaya baya akan wata na'ura. RAID guda ɗaya suna bi, inda lambar ke nuna takamaiman nau'in haɗi tare da kariyar bayanai (sai RAID XNUMX).

RAID 0 yana ƙirƙirar tsararrun faifai na gama-gari, amma ba kamar JBOD ba, an haɗa shi kuma an rubuta bayanai "hop-hikima" zuwa duk abubuwan da aka haɗa. Wannan shi ne yanayin da ya fi sauri wajen saurin canja wuri, amma a lokaci guda kuma yana da saurin rasa bayanai, domin idan faifan guda daya ya lalace, gaba dayansu za su lalace.
