Samsung 980 Pro 2TB $90

[majia]

你能不能先告诉我哪家主板有pcie 5.0？

X670E/B650E 主板

[majia]

这么快也没啥用。除非当内存缓存。可是现在内存也贼便宜，我倒是在琢磨用内存当硬盘呢

1TB 的内存？

现在SSD几乎都1TB起跳了

Z790主板就有pcie 5.0。

例如

只要999而已 便宜大碗

这纸面上 只支持 pcie 5.0 GPU

nvme 只是 pcie 4.0

私底下支不支持就不知道了

[马尾侠]

这纸面上 只支持 pcie 5.0 GPU GPU和SSD走一样的PCI总线。所以有人说，SSD慢了就是浪费带宽。
nvme 只是 pcie 4.0

私底下支不支持就不知道了用CrystalDisk 和 ATTO 测试，超过8GB / s就是PCIe 5.0

给你个4月份的旧闻
https://finance.sina.com.cn/tech/digi/2 ... 2391.shtml

根据 CrystalDisk 和 ATTO 的测试，该磁盘完全支持 PCIe Gen 5.0 x4。并且根据 ATTO 的说法，甚至可以在经济型主板上展示宣称的 10 GB / s 的速度。PCIe 4.0 接口的最大带宽为 8GB / s，而 PCIe 5.0 接口最高支持 16GB / s 的传输速率。

我说你链接里的主板

你给我看A620？

A620魔改版支持 pcie 5 有啥稀奇的

早就知道了

但不是所有A620都支持 pcie 5

买了一个 Samsung 980 2T NVMe PCIe 4.0 SSD, 准备 用在这个老机子PCIe 2.0 上 ：）
因为要用Dell reward & AMEX Plat Biz $200, 从Dell price match 后买的 $99.99 + tax

不知道

应该向前兼容吧？

准备插在PCIe 2.0 插口上？

旧主板不支持 PICe boot吧

只能当附加硬盘用

今天西数2T SN850X只要113，又降了。

就当硬盘用 ：）

那么旧的平台还留着做啥

当年我为了体验NVME 就升级了平台

后来为了体验NVME 4 就又升级了一次

现在NVME 5 都出来了

没毛用

gen3 跟 gen4 一般人都感受不到多少区别

gen5 也是一样 而且还贵

如果 gen3 能跑满都已经谢天谢地了

大家的nvme平常温度多少？我一个nvme放在usb外置盒里，不用都要60度，吓死了

插主板上平均40-50度

[iBull]

OS drive, Samsung 960 Pro, 一般听音乐上网看电影，35度。
这个就是NVME GEN3的好处。
从GEN4开始用电量剧增，所以我现在不考虑GEN4的NVME。
