开箱和硬件规格
金士顿 A400 SSD(Kingston A400 SSD)采用的包装小巧简洁。您可以看到型号名称(model name)、您购买的版本的容量以及SSD本身。
金士顿 A400(Kingston A400)采用 7 毫米外形尺寸(form factor)，适用于笔记本电脑和台式电脑。此型号提供多种存储容量：120 GB、240 GB、480 GB 和 960 GB。这些容量之间的数据传输速度各不相同，如下所示：
- 120GB — 高达 500MB/s读取(Read)和 320MB/s写入(Write)
- 240GB — 高达 500MB/s读取(Read)和 350MB/s写入(Write)
- 480GB — 高达 500MB/s读取(Read)和 450MB/s写入(Write)
- 960GB — 高达 500MB/s读取(Read)和 450MB/s写入(Write)
我们测试了您在下图中看到的 240 GB 型号。(GB model)金士顿 A400(Kingston A400)的外壳由轻质塑料材料制成，这款SSD 驱动器(SSD drive)仅重 1.4 盎司或 41 克。尽管金士顿(Kingston)声称A400具有抗冲击和抗振性(shock and vibration resistant)，但它感觉有些脆弱，我们不想测试它所说的坚固性。
该型号使用的接口是SATA Rev。3.0。使用的控制器名为 2 Ch² ，在其他型号的(Ch²)SSD驱动器上找不到。至少在写这篇评论的时候不是。金士顿 A400(Kingston A400)使用TLC NAND闪存存储数据。它是用于存储驱动器的最便宜的闪存形式，并且比用于更昂贵驱动器的其他类型的耐用性差。不建议将TLC NAND(TLC NAND)用于需要定期大量使用的持久存储的业务环境和用户。
硬盘空闲时的广告功耗(power consumption)为 0.195W，平均使用条件下的功耗为 0.279W。功耗(power consumption)偏低，使这款SSD成为(SSD)笔记本电脑用户的理想选择。工作温度(operating temperature)可以是32°F 到 158°F 或 0°C 到 70°C。

基准测试和 Windows 中的性能
我们将金士顿 A400 SSD 驱动器(Kingston A400 SSD drive)插入配备AMD Ryzen 5 1600 处理器、华硕 ROG STRIX X370-F GAMING 主板(ASUS ROG STRIX X370-F GAMING motherboard)、运行频率为 1600 MHz的 16 GB RAM DDR4（由Corsair制造）和MSI NVIDIA GeForce GTX 1060 OC的计算机中(OC 6GB)6GB显卡(video card)。您可以在下面的屏幕截图中看到有关它的更多详细信息，该屏幕共享详细的系统信息(system information)。
这台 PC 安装了Windows 10 Pro，并安装了所有最新更新。Windows 10可以毫无问题地识别驱动器并允许我们使用它。正如您在下面看到的，我们 240 GB 驱动器的实际可用(GB drive)存储空间(storage space)为223 GB。
首先，我们使用Windows 10(Windows 10)传输文件。我们拿了一个 4GB 的大文件并将其复制到另一个（更昂贵的）SSD上。金士顿 A400 SSD以大约 160 (Kingston A400 SSD)MB/second的速度写入该文件。
MB/second的速度读取相同的文件。
我们还使用基准来评估金士顿(Kingston)的速度承诺。我们运行的第一个基准测试应用程序是(benchmarking app)CrystalDiskMark，它执行多项测试以按顺序和随机读取和写入数据：
- Seq Q32T1 -具有多队列和线程的(multi Queues & Threads)顺序(Sequential)（Block Size=128KiB）Read/Write
- 4K Q8T8 -具有多队列和线程的(multi Queues & Threads)随机 4KiB(Random 4KiB) Read/Write
- 4K Q32T1 -具有多队列和线程的(multi Queues & Threads)随机 4KiB(Random 4KiB) Read/Write
- 4K Q1T1 -具有多队列和线程的(multi Queues & Threads)随机 4KiB(Random 4KiB) Read/Write
使用此应用程序测量的速度略好于金士顿(Kingston)宣传的速度，这很棒。
我们使用的第二个基准测试是DiskMark，它评估读取和写入性能，并自动计算您在文件传输期间获得的平均速度。此应用程序写入和读取数据包以确定磁盘的性能，并允许用户选择数据包的大小以及运行次数。这次我们获得的平均速度比金士顿(Kingston)宣传的要低。
最后，我们运行了AS SSD Benchmark，它在测试中与CrystalDiskMark类似。该基准测试确定驱动器的顺序和随机读写性能，测量读取和写入大小为 1 GB 的文件所需的时间。我们取得了不错的结果，但它们也不同于金士顿(Kingston)宣传的内容以及我们进行的其他测试。

Kingston A400 SSD: Who is it good for?
This SSD storage drive is a suitable choice for:

- Users who need an affordable storage solution to speed up their computers
- Mobile users who need an SSD drive with low power consumption
Pros and cons
Here are the pluses we identified for Kingston A400:
- The price makes it a natural choice for all budget users
- The performance you get is respectable, enough to speed up your computer in a noticeable way
- Low power consumption
The only downside to consider is the fact that this SSD drive uses TLC NAND, which makes it less durable than SSDs with other types of NAND flash memory. It is not recommended for business environments and users who need durable storage solutions.
Verdict
Kingston A400 is a great choice for budget users. If you need to speed up your PC and ditch the slow HDD drive that you have, Kingston A400 SSD is a good choice that delivers noticeable speed improvements. It is not the fastest SSD drive that you can get, nor does it use the most durable type of flash memory, but it does feature a 3 years warranty, and it gives you respectable performance at a low price that is hard to beat.
Unboxing and hardware specifications
The packaging used for Kingston A400 SSD is small and simple. You get to see the model name, the capacity of the version that you purchased, and the SSD itself.
Kingston A400 comes in a 7mm form factor that is suitable both for laptops and desktop computers. This model is available in several storage capacities: 120 GB, 240 GB, 480 GB, and 960 GB. The speed of data transfers varies between these capacities, as follows:
- 120GB — up to 500MB/s Read and 320MB/s Write
- 240GB — up to 500MB/s Read and 350MB/s Write
- 480GB — up to 500MB/s Read and 450MB/s Write
- 960GB — up to 500MB/s Read and 450MB/s Write
We tested the 240 GB model that you see in the picture below. The case of the Kingston A400 is made of light plastic materials, and this SSD drive weighs only 1.4 ounces or 41 grams. Even though Kingston states that A400 is shock and vibration resistant, it feels somewhat fragile, and we would not want to test its stated ruggedness.
The interface used by this model is SATA Rev. 3.0. The controller used is named 2 Ch², and it is not found on other models of SSD drives. At least not at the time this review was written. Kingston A400 uses TLC NAND flash memory for storing data. It is the cheapest form of flash memory for storage drives, and it is less durable than other types that are used in more expensive drives. TLC NAND is not recommended for business environments and users who need durable storage that is used heavily, on a regular basis.
The advertised power consumption is 0.195W when the drive is idle and 0.279W under average usage conditions. The power consumption is on the low side, making this SSD a good choice for laptop users. The operating temperature can be anything from 32°F to 158°F or 0°C to 70°C.

Performance in benchmarks and Windows
We plugged the Kingston A400 SSD drive into a computer with an AMD Ryzen 5 1600 processor, an ASUS ROG STRIX X370-F GAMING motherboard, 16 GB of RAM DDR4 running at 1600 MHz, made by Corsair, and an MSI NVIDIA GeForce GTX 1060 OC 6GB video card. You can see more details about it in the screenshot below, which shares detailed system information.
The PC had Windows 10 Pro installed, with all the latest updates. Windows 10 recognized the drive without issues and allowed us to use it. As you can see below, the actual storage space available for our 240 GB drive, was 223 GB.
First, we transferred a file using Windows 10. We took a large 4GB file and copied it to another (more expensive) SSD. Kingston A400 SSD wrote that file at a speed of approximately 160 MB/second.
It then read the same file at a speed of approximately 373 MB/second.
We also used benchmarks to evaluate Kingston's promises for speed. The first benchmarking app that we ran was CrystalDiskMark, which executes several tests for reading and writing data, both sequentially and randomly:
- Seq Q32T1 - Sequential (Block Size=128KiB) Read/Write with multi Queues & Threads
- 4K Q8T8 - Random 4KiB Read/Write with multi Queues & Threads
- 4K Q32T1 - Random 4KiB Read/Write with multi Queues & Threads
- 4K Q1T1 - Random 4KiB Read/Write with multi Queues & Threads
The speeds measured with this app were slightly better than those advertised by Kingston, which is great.
The second benchmark that we used is DiskMark, which evaluates both read and write performance and automatically calculates the average speed you get during file transfers. This app writes and reads data packages to determine the disk's performance and lets users choose a size for the packages, as well as the number of runs it makes. This time we obtained lower average speeds than those advertised by Kingston.
Lastly, we ran the AS SSD Benchmark, which is similar to CrystalDiskMark in the tests it makes. This benchmark determines the sequential and random read and write performance of the drive, measuring how long it takes to read and to write a file with a size of 1 GB. We had good results, but they were also different from what Kingston advertises, and from other tests that we ran.
