To ensure your results can be compared with other industry reports, verify that DDR cache in all HDDs are enabled for best performance. Even though DDR cache inside HDDs are volatile and considered unsafe, the industry seems to enable them during benchmarking.In HBA mode, the Sdparm CLI utility can be used to set a bit in the SSD’s mode page that enables drive write cache, where WCE means Write Cache Enable, and –S means Save, to be persistent across reboots (supported in Windows and Linux).> ARCCONF SETCACHE 1 DRIVEWRITECACHEPOLICY Configured 1 Unconfigured 1 hba 1.In RAID mode, maxView Storage Manager GUI / ARCCONF CLI is used to enable the drive write cache.The adapter supports commands to enable the drive write caches on all of the SSDs at once, for a given drive category.DDR cache inside modern SSDs are non-volatile and considered safe, therefore please verify that the drive write cache is enabled for best performance.Figure 1 – Common adapter settings with SSDs.To enable the DDR write cache, the DDR cache should be enabled, and the cache ratio should be set to 0% read and 100% write.The adapter’s DDR cache allows firmware to optimize the RAID algorithms used to efficiently stream sequential traffic to the HDDs.When attaching HDDs to the adapter, for RAID5/6/50/60 modes, enable the adapter DDR write cache.The DDR cache inside the HDDs can sufficiently stream sequential IO traffic.When attaching HDDs to the adapter, for RAID0/1/10 modes, disable the adapter DDR cache.The DDR cache can improve random performance for applications with small working sets with frequent reuse.The DDR cache can improve sequential write performance, especially at lower queue depths.When the DDR cache is enabled, IO Bypass is automatically disabled.The DDR cache only applies to RAID (no meaning in HBA mode).Enable the adapter’s DDR cache to optimize performance of solutions with light host workloads (single worker, lower queue depths…) and lower performing drive topologies (When IO Bypass is enabled, the adapter’s DDR cache is automatically disabled.IO Bypass only applies to RAID and SSDs (no meaning in HBA mode or with HDDs).Enable IO Bypass to maximize performance of solutions with heavy host workloads (many workers, higher queue depths…) and higher performing drive topologies (>300K IOPS).Verify that the adapter is functioning normally, e.g.Verify that the adapter is properly cooled as excessive heat can cause the adapter to dynamically throttle back performance to reduce power consumption and avoid overheating.Verify that the adapter is set to “maximum power” mode (default setting), and not “power saving” mode.

So, if you intend to modify the SATA settings to the mode described by this release, click the download button, and make the desired changes. Afterwards, perform a system reboot so that all changes take effect, enter BIOS menu, and set the SATA option to the mode that best describes the newly applied drivers. To perform the latter task, get the package, run the available setup and follow the instructions displayed on-screen for a complete installation.
If you want to change from one mode to another after the OS has been applied, appropriate drivers are required.īear in mind that if you modify these settings without installing proper files first, the operating system will not be able to boot until changes are reverted or required drivers are applied.
When you install an operating system, SATA settings (be it AHCI, RAID, or IDE mode) are detected from the BIOS. Close the wizard and perform a system reboot to allow changes to take effect.
Read EULA (End User License Agreement) and agree to proceed with the installation process. Allow Windows to run the file (if necessary). Locate and double-click on the available setup file. Unzip the file and enter the newly-created directory. Save the downloadable package on an accessible location (such as your desktop). To install this package please do the following: The Asmedia 106x SATA Host Controller Drive is designed to provide functionality for the following Storage Controllers:
