大部分使用Nas的人,在只有2bay情況下 應該都是組raid 1居多,
若是3Bay 應該都是Raid 5居多。
假如是4Bay,5Bay,甚至6-8Bay的Nas,大家常用的是raid幾呀?
小弟目前是Synology 918+,塞4顆10T,組Raid 5,使用空間為30T,可容錯一顆,
但考慮到安全性,未來擴充為8Bay時,應該會改raid 6,塞8顆10T,
此時可用空間為60T,容錯2顆。
不知大家在 4Bay以上的Nas都用raid 5 效能取向?
還是 Raid 6 安全取向 ? (但容錯也才兩顆,若是12Bay、甚至16Bay 容錯2顆感覺很抖)
還是 Raid 10 ? 安全取向(但一次掛兩顆同資料 也全死了...)
應該不會有人用raid 0 極速效能取向 (掛一顆 全死光 XD)
