As this isn’t official firmware, I’m not going to update all the published benchmark results, but to show demonstrate the difference: Unofficial AS2362 Firmware (Higher is Better) Conclusion Most current Linux distributions use fstrim.service and fstrim.timer to coordinate periodic SSD maintenance with TRIM. However USB connected SSDs do not automatically have TRIM enabled, instead requiring some manual configuration. The TRIM command can be issued manually using the fstrim command, for example the following code will run Trim on compatible file system mounted to /media/user/USBSTORAGE. Please note, all code examples in this document require root permissions unless otherwise noted.

Set NVMe early in the boot order

Modern hard drives and solid state drives include support for Self-Monitoring, Analysis, and Reporting Technology or SMART. SMART data can show signs of drive failure or wear before data loss occurs and can be used to monitor the health of the drive including the temperature sensors in the drive itself. From the Crystal Disk Info Graphical Utility

With a PCIe 4.0 x4 NVMe drive such as the FURY Renegadeor the KC3000you have read/write speeds of around 7,000/7,000MB/s or 56000Mbps. However, from what I can tell, USB4 enclosures don’t support PCIe 4.0 Running Hitachi’s “ HGST Align” tool may be necessary for Windows XP or Windows Vista users. Windows 7 and Windows 8 users should not need to use this utility. Windows support in the enterpriseThe ASM2464PD is also designed to be compliant with the Thunderbolt 4 specification and ASMedia is targeting the Thunderbolt certification by the end of Q2 2023. Once the certification has been granted, end-product devices utilizing the ASM2464PD would also be eligible for Thunderbolt certification testing." This one of the 512n volumes commonly used over the last decade. Support for these drives is universal. OS Support—SSD to USB adapter offers plug-and-play compatibility with Windows, Mac, and Linux. SSD file system must be supported on host operating system to be accessible There is also code in uas-detect.h that attempts to specific variants of the ASMedia chips that are all sharing the same pid and vid: /*

Of course, you'll also need to get Pi OS onto the NVMe, and there are a few ways to do that—I'll walk you through my favorite method below. The testbed hardware is only one segment of the evaluation. Over the last few years, the typical direct-attached storage workloads for memory cards have also evolved. High bit-rate 4K videos at 60fps have become quite common, and 8K videos are starting to make an appearance. Game install sizes have also grown steadily even in portable game consoles, thanks to high resolution textures and artwork. Keeping these in mind, our evaluation scheme for portable SSDs and UFDs involves multiple workloads which are described in detail in the corresponding sections.

The power LED behavior is also improved on Windows, and Intel based Mac systems: now when safely ejected the power LED should turn off ( it may blink slowly ) indicating the drive may be safely unplugged from the computer. To get the NVMe SSD to boot your Pi, it needs to have an OS. One option would be to clone an existing installation to it using rpi-clone or some other tool (see below), but my preferred option is to flash a fresh Pi OS install using Raspberry Pi Imager. I see this response is a couple months late but maybe it will help someone. I was able to get my cheap usb 3.1 nvme adapter with jms583 (gen 2) working with rpi4 8gb.
