[教學] 想行raid 0 nas 請問有乜選擇?

backup 會選擇 offline thr' ext hdd, 玩 nas 就是求高速吧!

心目中行 2 hdd就夠 (budget 有限), 上去 Q 記睇過隻ts-219 pii, 只 support raid 1, 請問仲有乜其他choice?

QNAP TS-219PII supports RAID 0.  Here is the specification -

By the way, I don't think many people get a NAS for speed.  If you want speed, why don't you use on-board RAID or SSD?

thanks Ching. I overlooked the Chinese website, as it only highlight supporting raid 1 in the general product description, forgot to look into the spec.

SSD no way la, still expensive in terms of money and capacity. Running raid 0 should be enough for attaining my expectation about speedy...

One strange thing I found from the website is that it states carrying 2 HDD Sata II, can it carry Sata III HDD?

san, nas 呢d野設計出黎唔係for速度, 主要係 for disk utilization.

SATA III 硬碟也是可以用的,但最好還是查看一下硬碟相容性列表

    靓仔,NAS是出Gigabit LAN的,虽然理论throughput最高125 MB/s, 但能上到100 MB/s的NAS价钱可观,款式也屈指可数。顺便话你知,事事旦旦揾只1TB以上3.5" HDD顺序读写都过100MB/s

    RAID 0? 认真諗多左。

RAID 0 have some usefull point
- Data strip store across several HD, it may good for some security issue
- It will increass I/O performance in some situation, i.e. several file access in same times

受教了, 大叔!!

我想如果raid 0未如想像中使用, 咁咪行返raid 1囉! 轉式硬蝶抄讀得多就慢下來, nas諗住用於video photo居多, 抄讀量不輕(多人使用), 所以咪想快一點囉!

另一方面, 行raid 0是否使用兩隻1T = 1T x 2 = 2T 總容量吧! 行raid 1咪即係兩隻 2T = 2T 總容量? 價錢上有差別吧!
