850 EVO系列是840 EVO系列的替代升级型号，延续了原厂主控、闪存、缓存、固件的四位一体优势，和840 EVO的相比，850 EVO的最大亮点是采用架构更为先进的3bit 3D V-NAND闪存，它的单位存储密度、P/E耐久度较之840 EVO的2D平面闪存有质的提升。搭载全新MGX主控，功耗表现更出色。性能方面，持续读写最高都是540MB/s、520MB/s，随机读写则是最高94000-98000 IOPS、88000-90000 IOPS。这个指标已经到了2.5寸盘的顶级水准。

原文： I purchased this drive (250GB) to replace the stock 128GB one that came with my MSI GSI 70 Stealth Pro laptop running Windows 8.1. As usual, Amazon delivered right on time, and I had the drive installed 20 minutes later (MSI sure does have a lot of screws holding their laptops together!). After quic
kly cloning my primary drive over to this one, it was ready for use.
,371
First thing I did was download and install the free Samsung Magician software (which as of version 4.6 now recognizes this drive as a Samsung drive) and ran a benchmark. Here are the results:

Sequential Read: 549 MB/s
Sequential Write: 523 MB/s
Random Read (IOPs): 97,371
Random Write (IOPs): 86,219

Then, I used the Samsung Magician software to enable RAPID mode. For those unfamiliar with RAPID, it is an acronym for Real-time Accelerated Processing of I/O Data and was first introduced with the 840 EVO series of drives. This feature has since been updated to v2.1 for this drive/version of Samsung Magician 4.6. In short, what it does is use up to 25% of your extra system RAM (up to 4GB maximum if you have 16GB+ of system RAM) and use it as a cache for your drive to improve the already blazing fast performance. This is completely automated and does help overall system performance, especially with commonly used applications as the software will cache them automatically for faster load times and decreased latency. Be sure you enable this feature on your drive.

Overall I am very satisfied with this drive. My boot times are around 10-15 seconds and I highly recommend it if you are thinking of purchasing this. The 5 year warranty sealed the deal for me.

译文：我购买这款250GB的硬盘，用来取代我以前128GB的硬盘，也在我配置有MSI GSI 70的Windows 8.1上运行。和以前一样的好用，在亚马逊上交付很准时，驱动器安装用了20分钟（MSI的笔记本电脑没有很多的螺丝钉，所有挺好拆卸！）我把我的主驱动器快速克隆到这个之后，就可以使用了。

我下载和安装的第一个东西是三星固态硬盘魔法师，4.6的版本把这个硬盘当做三星硬盘来运行，而且有了一定的基准。下面是我用了以后的结果。

顺序阅读速度：549 MB /秒
连续写入速度：523 MB / s
随机阅读（IOPs）：97,371
随机写入（IOP）：86,219

然后，我使用三星魔术师软件来启用快速模式。对于那些这个模式不熟悉的东西，它可以实时的缩写加速处理的I/O数据，首先引入驱动器的840 EVO系列。此功能已被更新到三星魔术师4.6的驱动器的v2.版本。总之，它使用了25%你额外的系统内存（如果你有多于16GB系统内存，那么最多可以用到4GB），用它来加速你的设备高速性能缓存。这是完全自动化的，并有助于整个系统的性能，特别是与常用的应用程序，因为软件将自动缓存，以实现更快的加载时间和减少延迟。请确保在驱动器上启用此功能。

总的来说，我对这个驱动非常满意。我的开机时间大约10-15秒，如果你打算买这个，我强烈推荐它。5年的质保可以很好的保证这笔交易。

原文： This SSD was purchased to upgrade the 128 GB mSATA SSD in my Samsung NP900X4C laptop. The 850 EVO is a perfect mechanical fit in this laptop. I used the Samsung Data Migration software and my mSATA to USB adapter to clone the 128 GB SSD. The cloning process went smoothly, the SSD installed easily, a
nd the laptop booted right up. I run a lot of simulations on this laptop and the 850 EVO is processing them with no problems. It's been running 24X7 for over a week now. I also installed and run Samsung Magician V 4.6 to optimize the operation of the SSD. This version recognizes the 850 EVO mSATA SSD.

译文：这个SSD固态硬盘是我买来用于升级我的三星NP900 X4C 笔记本的128 GB 的SATA SSD硬盘的。850 EVO是这台笔记本电脑里很完美的机械配置。我用三星数据迁移软件和我的mSATA的USB适配器来克隆我之前的128 GB的固态硬盘。克隆过程进行得很顺利，SSD很容易安装，笔记本电脑启动了。我在这台笔记本电脑和850 EVO的很多模拟处理过程中没有出现问题。它已经以24x7的速度运行了一周多。我还安装和运行了三星魔术师V 4.6来优化SSD的操作。这个版本可以识别850 EVO mSATA SSD的硬盘。

原文： As others have said, Samsung Magician does not, as yet, recognize this drive (v 4.5). Unlike what others have said, I had no problem using Samsung Data Migration software with this drive (v 2.7.1). You can still use Samsung Magician to run performance benchmarks (b/c that functionality works with a
ny installed drive - Samsung or not). You cannot, as yet, use the RAPID mode or Performance Optimization. Having said that, here are some performance comparisons. The mSATA Samsung 850 EVO showed Seq Read of 550 MB/s, Seq Write of 525 MB/s, Random Read of 97,209 IOPS, Random Write of 88,076 IOPS. By comparison, a Crucial MX100 installed in the same laptop showed: Seq Read of 559 MB/s, Seq Write of 507 MB/s, Random Read of 83,557 IOPS, and Random Write of 84,238 IOPS.

译文：正如其他人所说，三星魔术师至今还不能识别这款V 4.5的驱动。但是跟他们的不同，我使用三星数据迁移软件和驱动（V 2.7.1）的过程很顺利，没有出现什么问题。你仍然可以使用三星魔术师来运行和以前一样的性能基准（B / C功能可以与任何已安装的驱动器一起工作，不管是不是三星的）。到目前为止，还不能使用快速模式或性能优化。话虽如此，下面是一些性能比较。mSATA三星850 EVO显示：序列读取速度550 Mb/s，数据写入速度 525 MB/s，随机阅读（IOPs）：83,557，随机写入（IOP）：88,076 。相比之下，一个英睿达的MX100安装在同一电脑上会显示：序列读取速度559 Mb/s，数据写入速度 507 MB/s，随机阅读（IOPs）83557 ，随机写入（IOP）84238。

原文： I'm very pleased with this Samsung 850 ECO 250GB mSATA SSD from Samsung. I got it to upgrade a notebook computer for a client in my IT practice. I also took the opportunity to run a little performance testing. It did well.

I used crystaldiskmark to benchmark drive performance. It tests wi
th and without command queuing. Since all current operating systems I use (Windows 7 and later, Linux and Mac) all enable command queuing by default I'll focus on those results.

The drive does great with sequential reads/writes. I got reads of about 550MB/s and writes of about 512MB/s. Most SSD drives do fairly well on sequential read/write operations and this drive is only about 10% queued vs unqueued.

This 850 EVO drive did better than many other drives with random reads at about 300MB/s and writes at about 251MB/s. Unqueued reads were about 32MB/S (almost 1/10th the queued rate!) and writes were about 79MB/s (about 1/3 the queued rate). Command queuing makes a big difference with random access and makes this drive stand out for this use.

The mSATA form factor provides a SSD that is very compact compared to 2.5in drives. It has the same 6Gb/s data rate limit as 2.5in SATA drives. Other than size, connector or weight these are just like those physically larger drives SATA SSD drives. You can just stick SATA connector on this drive - it won't fit. If you want to use one of these in place of a 2.5in or 3.5in drive you'll need an adapter.

There is another kind of SSD that looks a lot like a mSATA and can be easily confused with it. The M.2 drive (aka NGFF form factor) uses a PCI-Express interface instead of SATA. M.2 drives are not at all compatible or interchangeable with mSATA! These are not limited by the SATA data rate bottleneck and if you have a compatible interface they can be MUCH faster than a SATA SSD!

In conclusion, this 850 mSATA is one of the faster SATA SSD drives ones I've used, especially on random reads/writes with queuing enabled. If your computer takes this form factor this is a great SSD. If you are replacing a 2.5in hard drive or SSD this is NOT a good choice: get the 2.5in version of this SSD!

This drive was perfect for this upgrade for my client. The laptop has both a 2.5in and mSATA bays making cloning very easy and quick. The old mechanical drive is now retired and their previously fairly fast laptop now just flies! With this sort of result I love this upgrade and drive. Definitely 5 stars.

译文：我很高兴获得这台三星850 ECO 的250GB固态硬盘。我在我的IT实践中用它为客户升级了一台笔记本电脑。我还利用这个机会进行了一些性能测试。它也让人很满意。

我用硬盘检测工具的基准去测试驱动器的性能。它在命令队列的情况下进行测试。由于我使用的所有当前操作系统（Windows 7和以后的Linux和Mac）都默认启用命令队列，所以我将重点放在这些结果上。

驱动器的连续读/写速度非常快。速度大约达到了550MB/s和512MB /s，在顺序读/写操作速度上，这个SSD硬盘运行的也很快，这个驱动也只出现了10%会排队的情况。

这款850 EVO读写速度比大多数驱动都快，自由读取速度大约是300MB/s，写入速度大约是251MB/s。无阻碍情况下，读取速度大约是32Mb/s（出现排队情况的概率是十分之一），写入速度79MB /s（约1/3的排队率）。命令队列运行很出色，随机访问也是，这使的这种驱动器在这种情况下脱颖而出。

mSATA还提供了一个SATA的驱动器，和2.5 英寸的驱动很挈合，它有着相同的6Gb / s的数据速率极限。除了尺寸，连接器或重量都使得它像那些物理上更大的SATA硬盘驱动器。如果你在这个驱动器上连接SATA连接器的话就会发现-它不能匹配。如果你想在它的上面使用其中的一个地方来连接2.5英寸或3.5英寸的驱动的话，你还需要一个适配器。

还有另一种SSD看起来很像一个mSATA，这使得人容易混淆。M.2接口（又名NGFF接口）使用一个总线接口代替SATA接口。M.2驱动根本不兼容或者可以与mSATA互换！这些不会受到SATA数据速率最大值的限制，如果你有一个兼容的接口，他们可以比SATA SSD快得多！

总之，这850个mSATA是我用过的一个速度很快的SATA SSD硬盘，尤其是在随机读取/写入排队功能上。如果您的计算机采用这种驱动的话，它会是一个很好用的固态硬盘。如果你换成2.5英寸的 SSD硬盘，或者说得到这个SSD的2.5英寸的版本可能不是一个好的选择！

这个驱动器对我的客户来说是一个完美的升级。笔记本电脑有一个2.5英寸的硬盘和mSATA驱动，这使得克隆过程变得非常容易，也很快。旧的机械传动装置现在已经被换下来，以前速度相当快的笔记本电脑现在可以更快了！有了这样的结果，我喜欢这个升级和驱动。肯定给五星好评啦。
