笔记本里面是不是装pcie3 ssd好一些。

pcie4太烫。

Gen 3一般人用不出区别，没特殊用途的买大牌便宜的。Gen 3里也有烫的和费电的，Nand和controller越新越好，TBW要求不特别高的QLC也比较成熟了。Crucial P3和Hynix P31都是效率极高又凉快，大牌5年保。

Gen 4也有不烫的，P3 Plus, load才60多度，ultrabook用没问题。速度达不到顶峰，5000左右。Tom上每款都有测温测效率。

多谢，dram有没有必要？

同代产品比较，有一般更好，但成本价格也高些, 发热也多些。我个人认为普通家用不用太在意，尤其是新一代比老一代。下面是Tom review P3 Plus的原话，P3 Plus用的是新一代的Phison E21T controller和QLC flash。

"This is noteworthy because newer, mid-range PCIe 4.0 drives are using four-channel DRAM-less controllers that can clearly match or exceed the Phison E16. Raw bandwidth is limited by the interface and we now have much more efficient drives - including the P3 Plus, using cheaper QLC - that can bring the same numbers."

"The P3 Plus performed surprisingly well, buoyed by its aggressively large SLC cache and many improvements to the QLC flash. Newer DRAM-less drives simply blow the old technology out of the water, which doesn’t hurt either. The drive is also incredibly efficient and cool-running which puts it in a good spot for laptops and the PS5. The warranty period is a solid five years and Crucial has sufficient software support. All of this is good news, particularly if you’re looking for an affordable 4TB SSD."

pcie 4 里 也有 凉快的。所以 要买 品牌的 笔记本，他们这些 都考虑过了。你要 扩展 laptop 的话，最好买 同样 牌子和 spec 的， ebay 上 找一下

我就在 ebay 上 找到 一模一样 估计 拆机的，把 RAM 从8G 扩展到 16G的
