Frequently Asked Questions

Part Specific FAQs

Are drivers needed for KC1000 NVMe drive?
The drivers for this drive are available for Windows 8 and higher and Server 2012R2 and higher. They can be downloaded within the installation or are already 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-NVME-01
Why does the performance of my NVMe drive decrease as the workload increases?
High-performance NVMe SSDs require 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 the proper operating temperature and ensure drive integrity. If performance degradation is observed within these circumstances, confirm that the SSD is receiving adequate cooling and/or increase the system’s fan speed to reduce drive temperatures. 

Note: Thermal throttling will engage when the temperature reaches 80°C FAQ: KSD-060117-NVME-02
Why are my benchmarking scores lower than expected for my NVMe drive?
Our NVMe SSDs rely 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 bypassing the DRAM cache often and writing directly to NAND. As a result of this behaviour, the NVMe SSD’s performance is reduced. To obtain maximum performance, you must disable write cache buffer flushing on the target drive within Windows. 

 
Steps to disable the write-cache buffer flush

1. Open Device Manager

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

3. Right-click and select Properties

4. Select “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.

OS/Compatibility FAQs

When performing a fresh installation or MacOS High Sierra on my new SSD, it states that the drive is not detected. It works fine if it is an upgrade installation. How do I resolve this?
During the OS installation, go to UTILITIES / TERMINAL 

In terminal type: 

diskutil list 

Then press RETURN. Scroll up to top and verify the Kingston SSD disk (i.e. disk0, disk1, etc).

Then type: 

diskutil mountDISK disk0 (or whichever ddisk is the Kingston SSD). 

Then press RETURN. It should show "mounted successfully".

Then type: 

diskutil eraseDISK apfs YOURDRIVENAME disk0 (or whichever disk is the Kingston SSD) 

Warning – This step (eraseDISK command) will delete all data on the target drive. Confirm that you have selected the drive you wish to delete and then continue. 

Then press RETURN. It should show "successful". Then exit terminal and proceed with the normal installation of the OS. FAQ: KSD-092917-GEN-21

More Questions

What is ESD?

ElectroStatic Discharge, ESD is simply the discharge of built-up static electricity. ESD should not be taken lightly as this is one of the few things that an individual can do to damage or destroy their computer or hardware components. It is like when you rub your feet on the carpet and you touch something metal. ESD can occur without the user feeling a shock and will occur when only working on the inside of the computer or handling hardware.

How to help prevent ESD
The best method of preventing ESD is to use an ESD wrist strap or an earthing mat or table. However, because most users do not have access to these items, we have included the below steps to help reduce the chance of ESD as much as possible.

  • Standing – We recommend that you are standing at all times when working on the computer. Sitting on a chair can generate more electrostatic.
  • Cables – Make sure that everything is removed from the back of the computer (power cable, mouse, keyboard, etc).
  • Clothes – Do not wear any clothing that conducts a lot of Electrical Charge, such as a wool jumper.
  • Accessories – To help reduce ESD and prevent other problems, it is also a good idea to remove all jewellery.
  • Weather – Electrical storms can increase the ESD risk; unless absolutely necessary, try not to work on a computer during an electrical storm. In very dry areas, the air itself becomes a part of the electrostatic build-up mechanism every time there is an air flow (wind, air conditioning, blower) passing over an insulated surface. Do not let high humidity levels build false confidence, and beware of corrosion problems with interconnects and other electrical interfaces.
