I notice the following comment in the description of the Intel® Solid-State Drive Toolbox:
Optimize the performance of an Intel SSD in RAID 0 using Trim functionality Intel® Rapid Storage Technology (Intel® RST) 11.0 or greater.
NOTE: Trim on RAID 0 is not supported on Windows 8* or Windows Server 2012*
Is this a temporary situation? What about on Windows 10? I thought it was generally agreed that Trim was pretty important to keep write amplification down thus maintaining high performance and extending the lifetime?
We understand the importance of TRIM and the benefits it provides to SSD's. The information currently available doesn't confirm if TRIM functionality is supported on RAID 0 on Windows 10* or not.
We will check further on this and will provide an update soon.
Trim for Intel® RST and RAID 0 was not supported at all under Windows 8 / 2012 due to some limitations with the Intel® RST driver.
This was fixed in Intel® RST driver release 18.104.22.1689, and the latest Intel® RST driver supports Trim for RAID 0 under Windows 8 / 8.1 / 10 and Windows Server 2012. This is natively supported by these OS versions and is normally enabled by default.
However, it is still not possible to run the Optimizer from Intel® SSD Toolbox with Intel® RST in RAID 0, under Windows* 8 / 8.1 / 10 and Windows* Server 2012.
You can find some additional information about TRIM in the following advisory:
