Frequently Asked Questions
Part Specific FAQs
The drivers for this drive are available for Windows 8 and up and Server 2012R2 and up by either downloading it within the installation or are built into the OS. We do not support using this drive with Windows 7 or below. It will work with newer Linux versions. Please verify if your distribution supports NVMe. These are not supported in any version of MacOS.
FAQ: KSD-060117-KC1000-01
KC1000 is a high-performance NVMe SSD and requires adequate airflow for maximum bandwidth and performance. During heavy workloads or extensive benchmarking, the drive will heat up and the controller firmware may implement thermal throttling in order to maintain proper operating temperature and ensure drive integrity. If performance degradation is observed within these circumstances, confirm the SSD is receiving adequate cooling and/or increase the system’s fan speed to reduce drive temperatures. 

Note: Thermal throttling will engage when SMART temp reaches 80°C
FAQ: KSD-060117-KC1000-02
Yes, the KC1000 supports bootable Intel RST RAID on platforms that support it. You will need to download the latest Intel RST "F6" driver and load it during Windows installation. Please refer to your motherboard manual for detailed setup instructions.The KC1000 will not support Intel RST RAID at launch. We are working diligently to ensure broad RAID compatibility in the near future. Please contact our Technical Support team for additional information.
FAQ: KSD-060117-KC1000-03
The KC1000 SSD relies on native Linux and Microsoft NVMe drivers. Microsoft’s native NVMe driver issues Forced Unit Access (FUA) IO writes and Flush commands to NVMe devices that have a volatile write cache. This, in effect, undermines the write caching on the target SSD by often bypassing the DRAM cache and writing directly to NAND. As a result of this behavior, the KC1000 SSD’s performance is reduced. To obtain maximum performance, you need to disable write cache buffer flushing on the target drive within Windows. 

Steps to Disabling Write-Cache Buffer Flush 

1. Open Device Manager 

2. Select Disk Drives and expand, then select target drive, SKC1000xxx. 

3. Right-click and select Properties 

4. Check “Turn off Windows write-cache buffer flushing on the device” 

a. Note: By disabling write-cache buffer flushing on the device, you run the risk of losing data in transit and/or data corruption in the event of a power failure. Only disable this feature if you are aware of the risks associated with it.
