请问6.10版本建议ssd用作数据盘吗

Featured Replies

之前看到个帖子,说是unraid不建议ssd做数据盘,fstrim会失效,用做缓存盘则没这个问题。我大概了解了下,就是ssd的存储优化功能吧,容量快满的时候也能保持高速读写。请问现在还有这个问题吗?

因为性价比和储存特性,并且故障后基本很难恢复数据,所以现阶段来说,ssd不适合做储存静态数据的磁盘。

感谢指点,我当前的序列没有校验盘,qb下载速度10MB/S都能把12500间歇性飙红,这还是只给了qb四个线程,其他没给的线程也会很高占用,我猜测是因为unraid读写性能的问题把?所以在考虑把硬盘直通给虚拟win10跑qb的可行性,unraid只给一个ssd用作虚拟机、docker的存储盘。只有一个ssd缓存盘的情况下无法启动序列,至少得有一个数据盘

不应该,10mb吞吐量不大,不要对docker进行线程限制设置,全部灰色即可,他们和unraid系统同享线程数,否则可能会有异常。vms可以设置线程限制。而unraid系统可以设置隔离限制,最好设置起码2核心+2线程。

搜索参考qb设置教程,限制一下U线程/内存占用和缓存读写频率

把docker的线程设置去掉之后,恢复正常啦!!

谢谢,之前已经按照这个设置。参考楼上,把docker的线程设置去掉之后,经过几天的观察,cpu占用率恢复正常啦
