最近 SSD 很便宜,但是普通消费级一般是 2T 居多,想看便宜大盘只能买 u.2 nvme 盘。最近全新铠侠 CD6 7.68T 只要 2000 左右,加上手里有一块去年买的 3.84T 的小海豚 PB5,打算把这俩盘直接装到群晖里做存储池。解决思路其实很简单,第一是要把群晖内部 m.2 引出来并转接成 u.2 接口;第二是要外接 u.2 的 12V 供电。我就把配件买一买,试试看能不能用。
|
||||||
|
|
||||||
|
我的机器是 DS1621+,m.2 在机器内部,反而没有四盘位的 DS420+ 这种方便。

## m.2 延长线
|
||||||
|
|
||||||
|
延长线我买的 ADTLink 的延长线,买了两种材质,都可以用
|
||||||
|

到手后按照下图插上后延长到机身外

## m.2 转 u.2 转接线
|
||||||
|
|
||||||
|
注意如果是 CD6 这种盘,最好是买这种先转 8639 再转 u.2 的线。安费诺原厂的线似乎不支持 4.0,卖家说是无法使用,我也不确定是会降速还是不能用。

## 12V 供电
|
||||||
|
|
||||||
|
12V 供电可以买普通 12V 圆口电源提供
|
||||||
|
|
||||||
|

但是这样会非常扭曲,因为我没找到 DC 转 SATA 供电的,只找到 SATA 转 DC 供电的。所以如果这样的话就是 电源转大4pin转SATA供电,不过我试过,能用的,没问题。
|
||||||
|
|
||||||
|
买 DC 转大 4pin 时注意它接的引脚,一定要接 12V 的。电源也要注意最大电流,CD6 最大电流是 2.6A,这导致 PASS 了很多直接提供大4pin供电的 DC 电源。
|
||||||
|
|
||||||
|
我最后采用的是 ATX 电源供电方案,因为我正好闲置一个电源。
|
||||||
|
|
||||||
|
配合开机线,最后就像这样子。(忽略左下的 eSATA 扩展柜)

## 成果
|
||||||
|
|
||||||
|
简单整理一下,再加一个风扇,最后效果就像这样。

至于 nvme 做存储池,网上教程一大把,按照步骤创建存储池即可。
