Another change is going to be with the SSD.

另一个改进就是固态硬盘。

It also controls the SSD and so on, but the real processor you care about is the Intel processor.

它还控SSD，但是我们真正关心它所用的英特尔处理器。

Here's a consumer class SSD, versus this enterprise class SSD.

下面是消费级 SSD 与企业级 SSD 的对比。

I've embraced USB-C with cables, with SSDs, but I always find myself needing an SD card slot.

我用过 USB-C 连接过充电线啦，SSD 啦，但总是觉得需要一个 SD 卡槽。

With that, this guy here I think had a similar effect on my mobile workflow, because this is a 7.6 tyerabyte external SSD.

我认为它和我这个移动硬盘效果差不多，因为这是一个7.6T的外部固态硬盘。

This is going to be all about how fast the SSDs are in all three of these systems.

这个测试是要比较这三个系统的固态盘到底有多快。

The base model here is a Core i5 with 8 Gig of RAM and 128 Gig SSD, and it costs $1,199.

这个基本型号的处理器是 Core i5，8g的 RAM 和128g的SSD，价格为1199美元。

So the configuration that we have here has a 64-core GPU, 128 gigabytes of RAM and two terabytes of SSD storage.

所以我们这里的配置有一个 64 核 GPU、128 GB 的 RAM 和 2 TB 的 SSD 存储。

So, by default, this will come with a 256 gig drive, however, you can option it all the way up to a 4TB SSD.

它默认是256G的硬盘，但是你可以选择最大的4T固态硬盘。

Additionally, within a single SSD chip such as this one, are multiple 3D NAND arrays stacked one on top of the other.

此外, 在像这样的单个SSD芯片中, 有多个3D NAND阵列堆叠在一起。

KIOXIA also manufactures a wide variety of SSDs and they have sponsored a couple of our videos that explore the inner workings behind how SSDs work.

KIOXIA 也生产各种各样的 SSD，并且他们赞助了我们的一些视频，探讨 SSD 工作背后的内部工作原理。

Today, costs have fallen so far, that hard disk drives are being replaced with non-volatile, Solid State Drives, or SSDs, as the cool kids say.

如今，成本已大幅下降，硬盘驱动器正在被非易失性固态驱动器或 SSD 取代，正如酷孩子所说。

First, we'll see exactly how the CPU communicates  and moves data from an SSD to DRAM.

首先, 我们将看到CPU如何通信并将数据从SSD移动到DRAM。

It's configurable with up to a 20-core CPU, a 64-core GPU, a 32-core neural engine, 128 gigabytes of unified memory and eight terabytes of SSD storage.

它最多可配置 20 核 CPU、64 核 GPU、32 核神经引擎、128 GB 统一内存和 8 TB SSD 存储。

So, the speed of 17 nanosecond DRAM versus 50 microsecond SSD is  like comparing a supersonic jet to a tortoise.

因此，17 纳秒 DRAM 与 50 微秒 SSD 的速度就像是将超音速喷气式飞机与乌龟进行比较。

You know, if you don't wanna spend as much as a nice used car, well, I guess a somewhat nice used car, as your SSD, there's your option.

你懂的，如果你不想花一辆二手车的钱，嗯，我猜是一辆挺不错的二手车，来买一个硬盘，你看着办咯。

Take a look at our 35-minute video on DRAM, but for now let's move on to SSDs which permanently store data in 3D arrays called 3D NAND.

请观看我们有关 DRAM 的 35 分钟视频，但现在让我们先讨论一下 SSD， 它将数据永久存储在称为 3D NAND 的 3D 阵列中。

This is because the main speed bottleneck for loading is predominantly limited by the speed of  the SSD or hard drive where the files are stored.

这是因为加载的主要速度瓶颈主要受到存储文件的SSD或硬盘驱动器速度的限。
