固态硬盘(state drive)( SSD ) 是提高计算机性能和速度的最佳解决方案之一。那是因为它们总是比带有旋转磁盘的传统硬盘驱动器更快。当今主要的SSD制造商之一是三星(Samsung)，这是一家众所周知的公司，尤其是智能手机。最近几天，我们测试了他们的三星 750 (Samsung 750) EVO固态硬盘(state drive)：这款设备承诺以合理的价格提供快速的读写速度。在这篇评论中，这是我们喜欢和不喜欢三星 750 (Samsung 750) EVO SSD的地方：(EVO SSD)
开箱和硬件规格
固态驱动器不是以精美包装出售的设备，其设计复杂。它们通常采用简单的准系统包装盒，三星 750 (Samsung 750) EVO也不例外。
这款SSD采用薄方形盒子包装，由哑光白色纸板制成。在盒子的上方，您可以看到SSD的图片、名称和存储容量(name and storage capacity)。
包装背面印有更多信息，包括保修信息。您会很高兴得知三星 750 (Samsung 750) EVO SSD享有 3 年有限保修。
在包装盒内，您会发现位于塑料托盘(plastic tray)上的SSD和印刷的保修声明摘要(Warranty Statement Summary)。没有别的了！
三星 750 (Samsung 750) EVO SSD的外形尺寸为 2.5 英寸，这意味着它既适合台式 PC，也适合笔记本电脑。
如下图所示，SSD通过(SSD)SATA 3连接器连接到您的 PC 。
确切的尺寸是 3.94 x 2.75 x 0.27 英寸（100 x 69.85 x 6.8 毫米）的宽度、高度和深度(height and depth)。如果您需要在便携式设备（如笔记本电脑或可转换 PC）中使用它，它尤其是一个不错的选择，因为它非常轻：重量不到 50 克。
三星(Samsung)生产和销售多个版本的 750 EVO SSD，具有不同的容量：120 GB、250 GB 和 500 GB。我们测试的样本有 250GB 的存储空间(storage space)。Windows 10 报告它的可用容量为 232 GB。
三星(Samsung)表示，750 EVO SSD能够以高达 540 MB/sec的速度读取数据，并以高达 520 MB/sec的速度写入数据。当然，这些是按顺序读取或写入数据时的最大理论速度。
这些速度是在三星 MGX 控制器和内部三星 NAND 闪存(Samsung MGX controller and Samsung NAND Flash Memory)的帮助下实现的。我们将在本次评测的稍后部分看到我们设法达到的真实速度。
如果功耗(power consumption)对您很重要，您应该知道 250 GB 三星 750 (GB Samsung 750) EVO SSD读取数据时的平均功耗(power consumption)为 2.1瓦(Watts)，写入数据时为3.7瓦。(Watts)

在基准测试中的表现
为了更好地了解三星 750 (Samsung 750) EVO固态硬盘(state drive)的性能和运行速度，我们使用以下测试系统(test system)运行了一些基准测试：
- 处理器：AMD FX-8350
- 主板：华擎 970 Extreme3
- 内存：HyperX Predator 8.00GB 双通道(Dual-Channel DDR3)DDR3，2133MHz
- 显卡：蓝宝石 AMD Radeon R9 270X (Sapphire AMD Radeon R9 270X)Dual(Card) -X
- 操作系统(Operating system)：Windows 10 Home 64-bit with Creators Update
我们使用的第一个基准测试应用程序(benchmarking app)是CrystalDiskMark，它运行多个测试以按顺序和随机读取和写入数据：
- Seq Q32T1：顺序(Sequential)（Block Size = 128 KiB）Read/Write，具有多个队列和线程
- 4K Q32T1：具有多个队列和线程的随机 4KiBRead/Write
- Seq：顺序(Sequential)（Block Size = 1 MiB）用单线程Read/Write
- 4K：使用单个队列和线程(queue and thread)的随机 4KiB读写(Read Write)
正如您在下面的屏幕截图中看到的，我们在测试系统上使用(test system)CrystalDiskMark测量的顺序读写速度非常接近三星(Samsung)宣传的 750 EVO固态驱动器(state drive)的速度。
为了获得第二意见，我们还使用另一个名为AS SSD Benchmark的流行(AS SSD Benchmark)SSD 基准测试(SSD benchmarking)应用程序进行了一些测试。虽然我们用AS SSD Benchmark(AS SSD Benchmark)测量的读写传输速度不如我们用CrystalDiskMark看到的那么高，但它们已经足够接近，可以确认这是一款快速驱动器。
我们使用AS SSD Benchmark运行的测试是：
- Seq：测试顺序read/write performance
- 4K：使用 4KB 数据块测试随机读/写性能
- 4K-64Thrd：使用 4KB 数据块和 64 个线程测试随机读写性能
- Acc.time：测量固态硬盘(state drive)的访问时间(access time)
在两个基准测试（CrystalDiskMark 和 AS SSD 基准测试）中，我们对 250GB 三星 750 EVO SSD 设法实现的写入速度印象深刻。在其价格范围内，有许多固态驱动器可以维持这些读取速度，但没有那么多可以维持相同的高写入速度。(In both benchmarks - CrystalDiskMark and AS SSD Benchmark - we were quite impressed by the writing speeds that the 250GB Samsung 750 EVO SSD manages to achieve. At its price range, there are many solid state drives that can sustain these read speeds, but there aren't that many which can sustain the same high writing speeds.)
捆绑软件：三星魔术师
在三星 750 (Samsung 750)EVO固态驱动器的(state drive)支持页面(support page)上，该公司提供的软件具有一个相当有趣的名称：三星魔术师(Samsung Magician)。所有三星 750 (Samsung 750)EVO用户均可免费使用。我们建议您下载并安装它，因为它将帮助您提高从新SSD获得的性能，并为其提供固件(provide firmware)更新并向您显示有关SSD的更多信息，例如其健康状态(health state)。
三星魔术师(Samsung Magician)软件最重要的功能称为RAPID 模式(RAPID Mode)。RAPID Mode是一种可以提高固态驱动器(state drive)速度的工具，它通过在计算机的RAM 内存(RAM memory)中创建和使用缓存系统，然后用于优化和增加(cache system)三星(Samsung)SSD上的读写传输。通过三星魔术师(Samsung Magician)用户界面的简单切换即可启用RAPID 模式(RAPID Mode)，只需重新启动系统(system reboot)即可开始工作。

Reviewing the Samsung 750 EVO - high-performance for moderate pricing
Solid state drives (SSD) are one of thе best solutions for improving the performance and the speed of our computers. That's because they are always faster than traditional hard drives with spinnіng discѕ. One of the major SSD manufacturers today is Samsung, a comрany which is known by everyone, especially fоr their smartphones. Theѕe last few daуs, we tested their Samsung 750 EVO solid state drive: a device that promises to deliver fast read and write speeds at a reasonable price. Hеre's what we like and what we don't like abоut the Samsung 750 EVO SSD, in this review:
Unboxing and hardware specifications
Solid state drives are not devices that are sold in spectacular packages, with intricate designs. They usually come in simple, barebone, boxes and the Samsung 750 EVO makes no exception from this rule.
This SSD is packaged in a thin square shaped box, made from matte white cardboard. On the upper side of the box, you can see a picture of the SSD, its name and storage capacity.
On the back of the package, there's more information printed, including information about your warranty. You will be pleased to learn that Samsung 750 EVO SSD benefits from a 3-year limited warranty.
Inside the box, you'll find the SSD sitting on a plastic tray, and a printed Warranty Statement Summary. There's nothing else!
The Samsung 750 EVO SSD has a form factor of 2.5 inches, which means that it will fit just as well in a desktop PC as it will in a notebook.
As you can see in the image below, the SSD connects to your PC via SATA 3 connectors.
The exact dimensions are 3.94 x 2.75 x 0.27 inches (100 x 69.85 x 6.8 mm) in width, height and depth. It's especially a good choice if you need to use it in a portable device, like in a laptop or convertible PC, because it's so light: it weighs less than 50 grams.
Samsung manufactures and sells the 750 EVO SSD in multiple versions, with different capacities: 120 GB, 250 GB, and 500 GB. The sample that we tested had 250GB of storage space. Windows 10 reported it to have a usable capacity of 232 GB.
Samsung says that the 750 EVO SSD is capable of reading data at speeds of up to 540 MB/sec and can write data at up to 520 MB/sec. Of course, these are the maximum theoretical speeds when data is read or written sequentially.
These speeds are achieved with the help of the Samsung MGX controller and Samsung NAND Flash Memory inside. We'll see later in this review what the real-life speeds that we managed to achieve are.
If power consumption is important for you, you should know that the 250 GB Samsung 750 EVO SSD has an average power consumption of 2.1 Watts when reading data and 3.7 Watts when writing data.

Performance in benchmarks
To get a better idea of the performance and operating speed offered by the Samsung 750 EVO solid state drive, we ran a few benchmarks, using the following test system:
- Processor: AMD FX-8350
- Motherboard: ASRock 970 Extreme3
- Memory: HyperX Predator 8.00GB Dual-Channel DDR3 at 2133MHz
- Graphics Card: Sapphire AMD Radeon R9 270X Dual-X
- Operating system: Windows 10 Home 64-bit with Creators Update
The first benchmarking app that we used was CrystalDiskMark, which runs several tests for reading and writing data, both sequentially and randomly:
- Seq Q32T1: Sequential (Block Size = 128 KiB) Read/Write with multiple queues and threads
- 4K Q32T1: Random 4KiB Read/Write with multiple queues and threads
- Seq: Sequential (Block Size = 1 MiB) Read/Write with a single thread
- 4K: Random 4KiB Read Write with a single queue and thread
As you can see in the screenshot below, the sequential read and write speeds we measured with CrystalDiskMark on our test system are very close to those advertised by Samsung for their 750 EVO solid state drive.
To get a second opinion, we also ran a few tests with another popular SSD benchmarking app called AS SSD Benchmark. Although the read and write transfer speeds that we measured with the AS SSD Benchmark are not as high as those we've seen with CrystalDiskMark, they are close enough to confirm that this is a fast drive.
The tests we ran with AS SSD Benchmark are:
- Seq: tests the sequential read/write performance
- 4K: tests the random read/write performance using 4KB blocks of data
- 4K-64Thrd: tests the random read/write performance using 4KB blocks of data and 64 threads
- Acc.time: it measures the solid state drive's access time
In both benchmarks - CrystalDiskMark and AS SSD Benchmark - we were quite impressed by the writing speeds that the 250GB Samsung 750 EVO SSD manages to achieve. At its price range, there are many solid state drives that can sustain these read speeds, but there aren't that many which can sustain the same high writing speeds.
Bundled software: Samsung Magician
On the support page of the Samsung 750 EVO solid state drive, the company offers software that bears a rather funny name: Samsung Magician. It's available for free to all Samsung 750 EVO owners. We recommend that you download and install it, because it will help you increase the performance you get from your new SSD, as well as provide firmware updates for it and show you further information about your SSD, like its health state for instance.
The most important feature of the Samsung Magician software is called RAPID Mode. RAPID Mode is a tool that can increase your solid state drive's speeds, by creating and using a cache system in your computer's RAM memory, which is then used to optimize and increase read and write transfers on Samsung's SSD. RAPID Mode is enabled with a simple switch from the Samsung Magician user interface, and it requires only a system reboot to start working.
The Samsung Magician software also shares information about the health of your SSD, the total amount of data written on it since the first day, the firmware version installed and the latest available, and so on.
You can also use a Performance Benchmark tool to see how fast your SSD is, and a Secure Erase tool to permanently delete data stored on your Samsung 750 EVO solid state drive.
The Samsung Magician software helps you boost your solid state drive's performance, upgrade its firmware when a new version is available, and it also shares useful information about the state of your SSS drive. We believe that the Samsung Magician is a great piece of software and we recommend that you use it.
Pros and cons
Here are the pluses we identified for Samsung 750 EVO SSD:
- It's a fast solid state drive, with high read and write speeds
- It costs less than other Samsung solid state drives
- The Samsung Magician software and its RAPID Mode can boost the SSD's performance even further
There are also a few downsides to consider:
- The 250 GB Samsung 750 EVO SSD is a bit pricier than other similar solid state drives from other manufacturers
- It has a warranty of three years, which means that it's clearly a consumer device, not aimed at businesses that require more endurance
Verdict
The Samsung 750 EVO solid state drive is a great choice for consumers who want a new storage drive. The 750 EVO offers high read/write speeds, and it's available in multiple storage capacity versions, ranging from 120GB to 250GB and up to 500 GB. Although the price for a unit is slightly higher than for other solid state drives manufactured by other companies, its performance is definitely great and you will enjoy using it.
