虽然固态硬盘的散热器一直是可选的,但如果你想最大限度地利用PCIe4 x4的速度,这一代的散热器已经成为必需品。雷克沙NM800 Pro包括一个选项,它也可以装在PS5里面。
Accessory Laptop / Notebook Desktop Storage

Lexar Professional 2TB NM800 Pro现在正在亚马逊上发货,价格为180美元或220美元。制造商给我们寄来了一个带散热片的样品,供我们做基准测试和印象。对于这项测试,我们特别感兴趣的是温度,以及该硬盘在保持7500MB/s的最大宣传读取率方面的能力。

我们测试NM800 Pro的主机是英特尔NUC11,配备11代酷睿i7-1165G7处理器。它支持PCIe4 x4传输速率,它甚至包括一个用于任何安装的固态硬盘的内置散热器,但我们已经在英特尔迷你电脑内移除这个散热器,以便测试雷克沙固态硬盘和散热器。

散热片已经安装好,保证适合PS5内部。

如果你想拆除散热器,需要飞利浦螺丝刀。

请记住,零售盒中不包括用于将硬盘固定在M.2插槽上的螺丝。相比之下,其他SSD制造商往往包括一个。希望你的主机设备已经包含了一个螺丝。

安装完毕后,我们将DiskSpd循环运行了半个小时,看看硬盘会变得多热,传输率是否需要节流。幸运的是,我们下面的图表和截图显示,该硬盘稳定在7100MB/s和合理的66C。尽管如此,看到NM800和散热器没有出现重大的温度或节流问题,这让人松了一口气。

为了说明SSD的散热片有多重要,我们用一块没有安装散热片的2TB SK Hynix P41 PCIe4 x4 NVMe SSD重复了上述测试。温度会达到93摄氏度,这就需要将性能节流到3500MB/s以下。简而言之,如果没有散热器,PCIe4驱动器的表现会更像PCIe3驱动器。

当然,用户仍然可以购买没有散热器的莱克赛尔NM800,以节省一些现金,但温度和性能的差异足以让我们尽可能地推荐使用散热器。
