我在RAID 5配置中使用英特尔快速存储技术配置了5个2TB Seagate SATA磁盘。
我对Read性能感到满意，但写入性能非常差。 希捷规格。 在单个磁盘上显示210 MB / s的最大持续传输速率。 我意识到RAID 5配置有一些开销，但31.85 MB / s顺序写入太低。 有谁知道如何提高我的RAID 5阵列的写入性能。 谢谢您的帮助。 基准测试结果： -------------------------------------------------- --------------------- CrystalDiskMark 6.0.1 x64（UWP）（C）2007-2018 hiyohiyo 水晶露世界：https：//crystalmark.info/ -------------------------------------------------- --------------------- * MB / s = 1,000,000字节/秒[SATA / 600 = 600,000,000字节/秒] * KB = 1000字节，KiB = 1024字节 顺序读取（Q = 32，T = 1）：751.966 MB / s 顺序写（Q = 32，T = 1）：31.850 MB / s 随机读4KiB（Q = 8，T = 8）：8.338 MB / s [2035.6 IOPS] 随机写入4KiB（Q = 8，T = 8）：2.071 MB / s [505.6 IOPS] 随机读4KiB（Q = 32，T = 1）：7.498 MB / s [1830.6 IOPS] 随机写入4KiB（Q = 32，T = 1）：1.466 MB / s [357.9 IOPS] 随机读4KiB（Q = 1，T = 1）：1.383 MB / s [337.6 IOPS] 随机写入4KiB（Q = 1，T = 1）：1.321 MB / s [322.5 IOPS] 测试：1024 MiB [D：0.0％（0.7 / 7452.0 GiB）]（x5）[间隔= 5秒] 日期：2018/08/26 17:35:29 操作系统：Windows 10 Professional [10.0 Build 17134]（x64） 系统信息： 操作系统名称：Microsoft Windows 10 Pro 操作系统版本：10.0.17134 处理器：GenuineIntel Intel64系列6型号158步进10 3.696 GHz BIOS：American Megatrends Inc.，1602 PCH：0xA2C9 英特尔®快速存储技术企业信息 套件安装：16.0.2.1086 用户界面版本：16.0.2.1086 语言：英语（美国） RAID选项ROM版本：16.0.2.3402 驱动程序版本：16.0.2.1086 ISDI版本：16.0.2.1086 存储系统信息 RAID配置： 阵列名称：SATA_Array_0000 大小：9,538,644 MB 可用空间：9 MB 卷数：1 卷成员：RAID5 阵列磁盘数量：5 阵列磁盘：Z4ZBPG4Q 阵列磁盘：Z4ZBKW1K 阵列磁盘：Z4ZBQ351 阵列磁盘：Z4ZBWYCL 阵列磁盘：Z4ZBPF6K 磁盘数据缓存：已启用 卷名：RAID5 状态：正常 键入：RAID 5 大小：7,630,907 MB 系统容量：没有 数据条带大小：128 KB 回写缓存：回写 初始化：是的 奇偶校验错误：0 有媒体错误的块：0 物理扇区大小：4096字节 逻辑扇区大小：512字节 硬件信息： 控制器名称：Intel（R）芯片组SATA / PCIe RST Premium控制器\ Scsi1 类型：SATA 模式：RAID SATA端口数量：6 卷数：1 卷：RAID5 备件数量：0 可用磁盘数：1 热插拔重建：已禁用 制造商：英特尔公司 型号：0x2822 产品修订版：0 直接连接磁盘：Z4ZBPG4Q 直接连接磁盘：Z4ZBKW1K 直接连接磁盘：Z4ZBQ351 直接连接磁盘：S3Z8NB0K535996Y 直连磁盘：Z4ZBWYCL 直接连接磁盘：Z4ZBPF6K 控制器0上的磁盘（在RAID 5配置中使用5个相同的2TB磁盘） 状态：正常 类型：SATA磁盘 位置类型：内部 用法：阵列磁盘 尺寸：1,863 GB 系统盘：没有 磁盘数据缓存：已启用 命令排队：NCQ 传输速率：6 Gb / s 型号：ST2000DM006-2DM164 SCSI设备ID：0 固件：CC26 物理扇区大小：4096字节 逻辑扇区大小：512字节 控制器0，端口3上的磁盘（适用于OS的Samsung SSD磁盘） 状态：正常 类型：SATA SSD 位置类型：内部 用法：可用 大小：932 GB 系统盘：是的 磁盘数据缓存：已启用 命令排队：NCQ 传输速率：6 Gb / s 型号：三星SSD 860 EVO 1TB 编号：S3Z8NB0K535996Y SCSI设备ID：0 固件：RVT01B6Q 物理扇区大小：512字节 逻辑扇区大小：512字节 其余的硬件配置： CPU：Intel - 酷睿i7-8700K 3.7GHz 6核处理器 CPU散热器：Cooler Master - Hyper 212 LED Turbo（红色）66.3 CFM CPU散热器 主板：华硕 - ROG MAXIMUS X HERO（WI-FI AC）ATX LGA1151主板 Memory Corsair - Vengeance RGB 32GB（2 x 16GB）DDR4-3000内存 存储SSD三星 - 860 Evo 1TB 2.5“固态硬盘 存储SATA（RAID 5）5 Seagate - Barracuda 2TB 3.5“7200RPM内置硬盘 视频卡华硕 - GeForce GTX 1070 8GB视频卡 Case Cooler Master - MasterCase Pro 5 ATX Mid Tower Case 电源Corsair - 850W 80+白金认证全模块化ATX电源 光驱华硕 - DRW-24B1ST / BLK / B / AS DVD / CD刻录机 SATA PCIe卡Vantec 2通道4端口SATA 6Gbps PCIe主机卡（UGT-ST622） 以上来自于谷歌翻译 以下为原文 I configured 5 2TB Seagate SATA disks using the Intel Rapid Storage Technology in a RAID 5 configuration.

Hellosharam55，我知道您目前使用新创建的RAID 5会遇到糟糕的写入性能。关于这一点，我想首先让您知道英特尔®快速存储技术允许您创建和管理RAID。
但是，它不会影响驱动器写入或读取速度的性能，这会受到SATA控制器或驱动器本身的影响。我们现在可以尝试，为了说明并确定，是 从系统中删除英特尔®快速存储技术。 您的RAID 5将保持创建状态，之后，您可以从非RAID驱动器（外部或内部）移动文件，并检查实际移动文件时显示的写入速度。如果您可以截取并附加它 将是伟大的。大卫V. 以上来自于谷歌翻译 以下为原文 Hello sharam55, I understand that you are currently experiencing bad writing performance with the newly created RAID 5. Regarding this, I would like to start by letting you know that Intel ® Rapid Storage Technology allows you to create and manage RAID. However, it does not affect the performance of the writing or reading speeds of the drives, this is something that is affected by either the SATA controller or the drives themselves. What we can try now, in order to tell and be sure, is to remove the Intel ® Rapid Storage Technology from your system. Your RAID 5 will remain created, after that, you can move a file from a non-RAID drive (External or internal) and check the writing speed shown at the moment of actually moving a file. If you could take a screenshot and attach it would be great. Regards, David V |

大卫你好，
感谢您的答复。 我在UEFI BIOS中使用英特尔快速存储技术创建了RAID 5阵列。 接下来，我在没有安装IRST的情况下加载了Windows 10。 我检查了磁盘的i / o性能，但很差。 然后我加载了IRST设备驱动程序和软件。 写入性能仍然很差。 我认为IRST在两个地方，在RAID设置期间的BIOS中以及用于管理磁盘阵列的OS中。 我可能错了。 我很乐意加入截图。 但我不确定是什么？ 谢谢， Sharam 以上来自于谷歌翻译 以下为原文 Hello David, Thank you for your response. I created the RAID 5 array using Intel Rapid Storage Technology in UEFI BIOS. Next, I loaded Windows 10 without installing IRST. I checked disk i/o performance and it was poor. Then I loaded IRST device drivers and software. The write performance remained poor. I think IRST is in two places, in the BIOS during the RAID setup and in the OS for managing the disk array. I may be wrong on this. I will be happy to include screenshots. But I am not sure of what? Thanks, Sharam |

Hellosharam55，感谢您的回复。但是，正确的是，英特尔®快速存储技术只能帮助您创建和管理RAID，但不会影响性能。 请尝试将文件从SSD（例如）或任何其他驱动器（内部或外部）移动到RAID，并查看传输所需的时间，以确保传输速率不受影响。如前所述，此性能 问题可能是由于SATA控制器出现问题或者在这种情况下出现故障或有缺陷的驱动器，可能会影响RAID的整体性能.Readards，David V 以上来自于谷歌翻译 以下为原文 Hello sharam55, Thank you for your response. That is correct, however, the Intel ® Rapid Storage Technology only helps you create and manage the RAID but it does not affect the performance. Please try to move a file from the SSD (For example) or any other drive (internal or external) to the RAID and see how long it takes to transfer to make sure that the transfer rate is not affected. As mentioned before, this performance problem is possibly happening because of a problem with the SATA controller or in this case a faulty or defective drive that may be affecting the overall performance of the RAID. Regards, David V |

Hellosharam55，我跟进你的情况，看到我们没有收到你的回复。你能测试转移速度吗？如果你需要更多的帮助，请不要犹豫回复.Regards，David V 以上来自于谷歌翻译 以下为原文 Hello sharam55, I am following up with your case and see that we have not heard back from you. Were you able to test the transfer speed? If you need more assistance do not hesitate to reply. Regards, David V |
