M.2 SSD

Why does my M.2 NVMe SSD not achieve its prformance specs in benchmark tests?


Benchmark test results may differ depending upon the system environment, host software and hardware configuration.




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 70°C




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” 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.




How can I enhance SSD performance if my operating system does not support TRIM?


For operating systems that do not support TRIM command, the SSDs utilize an intelligent garbage collection algorithm to help manage data and maintain peak performance.




What is the physical size of a addlink M.2 NVMe SSD? Will it fit my PC?


addlink NVMe SSDs use the M.2 (2280) form factor. M.2 is an industry standard, and M.2 SSDs typically measure 22mm in width. Various standardized lengths range between 30mm and 110mm, with the 80mm solution used by addlink being the most common. This means that addlink NVMe SSDs are 22mm wide and 80mm long, and should physically fit in the majority of M.2 slots on mainboards.




What is an "M-key"? What is a "B-Key"?


"M" and "B" are different connector types for M.2 slots. A"B-Key" enables SATA or PCIe NVMe SSDs using up to 2 PCIe lanes, and an"M-Key"enables using up to 4 PCIe lanes. Please note that addlink NVMe SSDs use the"M-Key" (to leverage PCIe x4 for maximum performance) and cannot be plugged into an M.2 slot with a "B-Key".




What is M.2?


M.2 is a form factor that enables expansion, contraction, and a higher integration of functions onto a single form factor module solution. M.2 SSD includes a smaller form factor with larger capacity than that of mSATA and Half-slim.




What is PCIe Gen4, and how is it different than PCIe Gen1/2/3?


PCIe Gen4 is a new standardized data transfer bus that will double the data transfer rate per lane of the prior Gen3 revision from 8.0 GT/s (gigatransfers/second) to 16.0 GT/s. This means that a single PCIe Gen4 interconnection will allow data rate transfers of up to 2GB/s (gigabytes/second), and a full 16 slot PCIe Gen4 interconnection for graphics cards and high-end solid state drives will allow data transfer rates of up to 32GB/s.

This increased data transfer rate will facilitate the demanding data transfer rates of new servers and data farms as cloud storage, services, and software become more and more prevalent. It will also allow mobile devices to transfer information super quickly, thus reducing power consumption during downloads or data synchronization activities.

PCIe 4.0 SSD delivers incredible storage performance, delivering up to 10 times the sequential read and sequential write speeds of some SATA SSDs and up to 50 times the speed of some traditional HDDs and is also fully backwards compatible with current PCIe 3.0 platforms.

*Please use PCIe 4.0 motherboard for the best performance, performance may vary based on system hardware and configuration.

*Please make sure that your computer has a M.2 slot. Backwards compatible with PCIe 3.0 platforms.





COMPATIBILITY​

Are addlink NVMe M.2 SSDs delivered with a screw?


addlink NMVe M.2 SSDs are not delivered with a screw. This is because mainboard manufacturers typically provide the specific screws and spacers that fit the proprietary needs of each mainboard.




BIOS/UEFI Configuration for Optimizing M.2 PCIe NVMe SSDs


When installing a new M.2 NVMe PCIe SSD, you may see some messaging around configuring to increase speeds of NVMe SSDs, or enabling and disabling shared bandwidth of SATA and NVMe ports. We are not able to assist with this in detail due to variations between applicable systems, but it is not a malfunction. Understanding the concepts behind this and where to seek detailed information will allow you to configure your hardware for optimal performance and avoid actual malfunctions, such as SSDs and hard drives not being detected in a system. Your system may have a PCIe x4 mode which is optimal for NVMe SSD performance. In many systems, M.2 ports can be configured in the BIOS or UEFI to toggle this, speeding up connected NVMe drives by removing bandwidth from other ports (typically disabling them in the process), or limiting their performance to maximize available ports if preferred. While this could be an automated function, it can also be described in a message appearing when an NVMe-compatible slot is populated, or may be mentioned specifically in your system or motherboard manual so you can familiarize yourself with the feature prior to installing hardware. To manually make these adjustments, refer to support for your system or motherboard for detailed assistance, or any help or tooltips available in your system's BIOS/UEFI itself.




Can I use a NVMe M.2 SSD at the same time as s SATA SSD or HDD?


Yes. There are no technical limitations in using an NVMe M.2 SSD concurrently with a SATA SSD or HDD. Please make sure your mainboard has a sufficient number of interfaces to accommodate multiple storage devices.




Can NVMe M.2 SSDs be RAIDed?


Yes. the NVMe M.2 SSDs can be grouped into a RAID formation. Please ensure that your mainboard has a sufficient number of NVMe M.2 slots and that sufficient PCIe lanes are available for maximal performance.




I'm unable to boot from my M.2 PCIe. What can I do?


This can have multiple reasons. Please ensure that your system or motherboard supports NVMe. If it doesn't, you will be able to use M.2 PCIe as a storage device only, not as a boot device. If you have made sure that your system or motherboard supports NVMe and you're unable to boot from an OS installed on M.2 PCIe, please review the following points: Is the drive recognized in the BIOS/UEFI? Is M.2 PCIe on top of the boot priority list? Is your system's or motherboard's BIOS/UEFI up to date? If you use an onboard M.2 slot, could this slot's bandwidth be shared with any other media in use? Your system/motherboard manual contains information on media bandwidth sharing If you use M.2 PCIe in a PCIe slot, could this slot's bandwidth be shared with any other media in use? Your system/motherboard manual contains information on media bandwidth sharing.




How do I install a M.2 PCIe as a boot drive?


To install your M.2 PCIe as a boot drive, please make sure the following criteria are met: - Your motherboard or system has a free PCIe or M.2 slot - Your motherboard or system supports NVMe (please see the manufacturer's manual) - The slot you chose to install M.2 PCIe in does not share resources with another device that could render said slot unusable (Example: M.2 slot disabled if certain SATA ports are used, refer to manufacturer's manual) - Ensure that the install media you wish to use contains the latest version of the OS you are about to install. Windows 8.1 and later have integrated NVMe drivers and don't require additional drivers to complete the setup. Windows 7 did not support NVMe when it was released. With the requirements met, please install M.2 PCIe in the desired slot and insert the OS install media. The following process should be similar to installing the OS to a SATA drive: 1. Boot from the OS install media 2. Choose the desired drive to install the system on 3. Complete the installation 4. Reboot and enter BIOS 5. Adjust the boot priority list to move M.2 PCIe to the top of the list (alternatively, the "Windows Boot Manager" on M.2 PCIe in case of an UEFI install)




Platform won't wake up from Sleep Mode after Windows Update?


There may be a compatibility issue between your SSD and the platform. Please follow the steps below to troubleshoot (listed in order of likelihood): 1. Please also make sure your platform BIOS is up-to-date. 2. For Windows OS, we suggest any version later than 1709. (Check your OS version in Settings -> System -> About) 3. Download and install the latest driver for all devices (e.g. chipset, power management, display card, etc.) used on the platform from their official websites.




My M.2 PCIe doesn't work as expected! How do I fix this?


First of all, it is critical to understand what exactly doesn't work. Please see the reference points below: 1. BIOS/UEFI doesn't recognize the drive, and the OS installer doesn't see the drive as well. 2. Does your system or motherboard support NVMe? Please verify with the manufacturer of your system:
