NVMe P4600的速度部分低于SATA SSD?

你好,
我有一台配备4TB的Intel P4600 DC和一台Samsung 850 EVO 500GB(普通SATA)。
即使使用旧的英特尔SSD 520系列,读取的结果也没有那么不同!
对于小文件,三星SATA SSD如何能够胜过英特尔NVMe SSD(读取速度)?
P4600使用最新的固件(使用当前的数据中心工具)进行更新,并使用最新的英特尔驱动程序运行(Windows驱动程序甚至更慢!)
这是正常行为还是配置/软件问题?
Intel P4600 DC NVMe(PCIe 3.0 x8端口):
三星850 Evo(SATA 3.0):
英特尔520系列(SATA 3.0):

Hello,

i have one Intel P4600 DC with 4TB and one Samsung 850 EVO 500GB (normal SATA). Even with an old Intel SSD 520 Series the results in reading are not that different!
How is it possible that with small files the Samsung SATA SSD outperforms the Intel NVMe SSD (in read speed)?

The P4600 ist updated with the latest Firmware (with the current datacenter tool) and runs with the latest intel drivers (the windows drivers are even slower!)
Is this a normal behavior or a configuration/software problem?

Intel P4600 DC NVMe (on PCIe 3.0 x8 Port):

Samsung 850 Evo (SATA 3.0):

Intel 520 Series (SATA 3.0):

您好JemandAnderes,感谢您在英特尔®SSD社区中发布您的问题。对于需要进行比较的SSD标记,需要在相同条件下使用特定程序和SSD进行比较,以确保获得预期结果。
例如,您的操作系统是否安装在P4600中?
如果安装了操作系统并在同一台P4600上运行基准测试,这就是为什么读取讲座低于应有的原因。
由于此SSD在基准测试工具之上运行各种任务。英特尔对SSD进行基准测试的程序如下:https://www.intel.com/content/dam/support/us/en/documents/ssdc/hpssd/ssd
-750 / *** / intel_ssd_750_series_evaluation_guide_332075002us.pdf建议的基准测试工具如下:http://www.iometer.org/doc/downloads.htmlhttps://crystalmark.info/en/software/crystaldiskmark/另外,在检查了唯一的讲座后
较高的是初始读数,在512KB之后P4600在速度上运行并且它甚至不接近其他2,在基准测试中结果比较是在最高使用峰值的最高速度完成而P4600更快
比其他2个SSD。
由于PCIe端口比SATA端口快,这将是正常行为。
你有多少次进行过这项测试?
我会等你的反馈。
希望这些信息有助于澄清您的问题。
最诚挚的问候,Juan N.

Hello JemandAnderes,

Thanks for posting your question in the Intel® SSD community.

Benchmarking for SSDs for comparison needs to be performed with specific procedures and with SSDs under the same conditions to make sure you are getting the expected results. For instance, is your OS installed in the P4600?

If the OS is installed and running the benchmark on the same P4600, this would be the reason why the read lectures are lower than what it should. Since this SSD is running various tasks on top of the benchmarking tool.

Intel’s procedure to benchmark SSDs is the following:
https://www.intel.com/content/dam/support/us/en/documents/ssdc/hpssd/ssd-750/***/intel_ssd_750_series_evaluation_guide_332075002us.pdf

The recommended tools for benchmarking are the following:
http://www.iometer.org/doc/downloads.html

https://crystalmark.info/en/software/crystaldiskmark/

Additionally after checking the only lectures that are higher are the initial Reads, after 512KB the P4600 runs away in speed and it is not even close to the other 2, in benchmarking the result comparison is done at the highest speed in the highest peak of usage and the P4600 is way faster than the other 2 SSDs. Since the PCIe port is faster than the SATA port this would be the normal behavior. How many times have you performed this tests?

I will be waiting for your feedback. Hope this information helps to clarify your questions.

Best Regards,
Juan N.

感谢您的回答!
需要使用特定程序和SSD在相同条件下执行用于比较的SSD的基准测试,以确保获得预期结果。

- >不,我在同一系统上进行了所有测试。
所有SSD都完全没有问题。
操作系统安装在另一个驱动器上
所以我所做的所有测试都有相同的条件。
此外,在检查了更高的唯一讲座是初始读数之后,在512KB之后,P4600的速度会逐渐消失
- >这是真的,但为什么会这样呢?
即使使用小数据(小型图片的数据库/访问),我也购买了高速P4600,但是现在我的小型HDD RAID阵列比这个P4600的数据更小。
我甚至尝试将这些P4600中的4个一起堆叠在一个Windows存储池中,但即使在raid 0模式下(我知道还是软件,但仍然)它们会粉碎hdd数组。
这就是我觉得有点令人失望的原因,因为我认为这些NVMe SSD会更快。
我将再次尝试使用IOMeter和CrystalDiskMark。

Hello Juan,
 
thanks for your answer!

-> No i did all the tests on the same system. All SSDs are completely empthy. OS is installed on another drive. So there are the same conditions for all tests i made.
 
Additionally after checking the only lectures that are higher are the initial Reads, after 512KB the P4600 runs away in speed
-> This is true, but why is this? I bought the P4600 for high speeds even with small data (Database/Access of small pictures), but for now even my small HDD RAID Array is FASTER than this P4600 with small data. I even tried to stack 4 of these P4600 together in a windows storage pool, but NOT even in raid 0 mode (i know softraid but still) they smash the hdd array. Thats what i find a bit disappointing, because i thought these NVMe SSDs would be way faster.
 
I'll try it again with IOMeter and CrystalDiskMark.

您好JemandAnderes,我一直在研究您的问题,我能够找到有关ATTO基准测试工具以这种方式显示信息的原因的信息。首先,我找到了P4600的评估指南:http://manuals.ts。
fujitsu.com/file/12176/fujitsu_intel-ssd-dc-pcie-eg-en.pdf最初,并非所有基准测试工具的行为都相同,或者在运行测试时以相同的方式处理数据。
我找到了以下线程,解释了ATTO和crystaldiskmark如何处理信息的区别.https://linustechtips.com/main/topic/682597-why-do-crystaldiskmark-and-atto-benchmarks-report-different-values
/有几个客户与其他测试有同样问题的报告,这是一个例子:https://www.overclock.net/forum/21-benchmarking-software-discussion/1060279-atto-vs-crystaldiskmark。
htmlHere是另一篇文章,你可以查看它作为参考,它涵盖了市场上一些基准测试工具之间的区别:http://www.thessdreview.com/our-reviews/runco​​re-t50-6gbs-msata-120gb-ssd-review
-atto-crystal-disk-mark-and-anvil-storage-utilities /您是否使用crystal diskmark进行了测试?希望所有这些信息对您有所帮助。
如果您有任何其他问题,请告诉我。最好的问候,Juan N.

Hello JemandAnderes, 

I have been researching on your issue and I was able to find information for the reason why the ATTO tool for benchmarking shows the information this way. 

First I found the evaluation guide for the P4600: 

http://manuals.ts.fujitsu.com/file/12176/fujitsu_intel-ssd-dc-pcie-eg-en.pdf

Initially, not all Benchmarking tools behave the same or treat data the same way at the time of running the tests. I have found the following thread that explains the difference on how ATTO and crystaldiskmark handle the information. 

https://linustechtips.com/main/topic/682597-why-do-crystaldiskmark-and-atto-benchmarks-report-different-values/

There are several reports of customers having the same issue as you with other tests, here is an example: 

https://www.overclock.net/forum/21-benchmarking-software-discussion/1060279-atto-vs-crystaldiskmark.html

Here is another article that you can check as a reference which covers the difference between some benchmarking tools in the market: 

http://www.thessdreview.com/our-reviews/runcore-t50-6gbs-msata-120gb-ssd-review-atto-crystal-disk-mark-and-anvil-storage-utilities/

Have you performed the tests with crystal diskmark?

Hope all this information helps you. Let me know if you have any additional questions.

Best Regards, 
Juan N.
