SSD Enclosure

事情开始于我旧的硬盘盒频繁弹出「未正确退出磁碟」。
于是采购了一只 ROG Strix Arion 硬盘盒,ASM2362 主控,花费 ¥279,我知道这个钱可以买个 256GB 的 SSD,但是笔记本用户你知道的。
SSD 用的是 WD SN550,性能够用。旧的硬盘盒是 ACASIS 的,JMS583 主控,做工不行,华强北小作坊的级别。
大概长这样,还行。
原本是有个小塑料片会导致盖不太紧,拆掉了。
用取卡针可以打开。
很方便,但大大的缝隙给人一种不是很牢固的感觉。
可爱接口。
RGB。
然后是速度比旧硬盘盒慢一点,发热也小一点。

下面是一些要考的重点:

  • 5Gbps:USB 3.2 Gen 1×1=USB 3.2 Gen 1=USB 3.1Gen 1=USB 3.0,USB 3.2 Gen 1
  • 10Gbps:USB 3.2 Gen 2×1=USB 3.2 Gen 2=USB 3.1 Gen 2=USB 3.1,USB 3.2 Gen 1×2
  • 20Gbps:USB 3.2 Gen 2×2
  • 40Gbps:Thunderbolt 3,Thunderbolt 4,USB4

We now find ourselves in a similar spot with USB 3.2. The newest, fastest version of USB 3.2 offers a max speed of 20Gbps and is called USB 3.2 Gen 2×2. (The 2×2 means it’s the second generation and has two 10Gbps lanes to achieve its maximum throughput of 20Gbps.) The older USB 3.1 has a single 10Gbps channel and is called USB 3.2 Gen 2. Then there’s USB 3.0, which is now called USB 3.2 Gen 1.

All USB 3.2 Gen 2×2 products use the Type-C connector, but not all USB-C ports are USB 3.2 Gen 2×2. A USB-C port can be either 20Gbps USB 3.2 Gen 2×2 or 10Gbps USB 3.2 Gen 2. A USB Type-A port can be 10Gbps USB 3.2 Gen 2, 5Gbps 3.2 Gen 1 or even USB 2.0. USB 4 will clear up this confusion next year, but until then you’ll need to read the fine print on products to ensure you’re getting the expected USB 3.2 connection between your devices.
