问大家
: What's the difference between the 990 Pro and the 990 Evo? 和 990 pro 990 evo 有啥区别
: There's not much difference for everyday use. I'm using the 980 Pro and 990 Evo. 日常用差别不大吧，我用的就是 980 pro和 990 evo
: 990 EVO is cacheless, while the 990 Pro is significantly faster, but for daily use, it doesn't really matter. You can't even tell the difference with PCIe 3.0. The 990 EVO Plus is currently the best all-around option, especially for laptops. It's cacheless, with performance on par with the 980 Pro, and runs cool![[倒过来笑]](/assets/emoji/comment-emoji/dm_daoguolaixiao@2x.png?v=1)
. 990evo无缓，990Pro要快很多，但日常其实无所谓。3.0都用不出来，990evoplus算是目前综合最好的尤其笔电上。无缓/性能持平980Pro/低温![[倒过来笑]](/assets/emoji/comment-emoji/dm_daoguolaixiao@2x.png?v=1)

: A year ago, nobody even wanted QLC for free, and now it's selling for over 300 bucks![[裂开]](/assets/emoji/comment-emoji/dm_liekai@2x.png?v=1)
一年前送都没人要的qlc，现在卖300+![[裂开]](/assets/emoji/comment-emoji/dm_liekai@2x.png?v=1)
: 400TBW suspected QLC? Confusing model numbers trying to slip through the cracks. 400tbw疑似qlc？莫名其妙的型号像浑水摸鱼
: No need to speculate, it’s QLC. It works, but the question is whether the price can drop further. As long as QLC doesn’t have cache performance issues, it won’t be exposed. 不用疑似了，就是QLC，能用就是看价格还能跌不。QLC只要不出缓性能问题不会暴露
回复 @Lawrence011 : Times have changed. This thing dares to call itself 990?![[二哈]](/assets/emoji/comment-emoji/dm_erha@2x.png?v=1)
The price is twice that of a second-tier TLC. 世风日下 这种也配叫990![[二哈]](/assets/emoji/comment-emoji/dm_erha@2x.png?v=1)
定价是二线tlc两倍
