X400 series M.2 NVMe 2280 PCIe 4.0 SSD

This is great. I have a small home lab and needed to expand my small HP prodesk. Easy to install and very fast. Good quality and no issues. great value for the price.

I installed the 512 GB SSD into a USB4 enclosure with a cooling fan. The drive shows up as /dev/sdb in the terminal. I checked the disk details and saw it reports 476.94 GiB of usable space. The model name reported by the operating system is ASM246X. The drive arrived unformatted and I formatted it to the exFAT file system. The file manager lists the volume size as 477 GB. It works with my Android 14 phone with OTG support, my Windows PCs, and my Linux rig.The installation was easy. I inserted it at a slight angle. I added a thermal pad and a cooling vest. I doubt the SSD will reach a dangerously high heat level this way. So far, it has been working reliably.I did a benchmark test using Gnome's Disks program. The results I got: the average read speed reached 44.6 MB/s. The write speed averaged 43.6 MB/s. The access time measured 0.25 milliseconds. I think I would get faster speeds if I used a USB-C connection and used it as an internal drive. I used f3probe to verify the device's integrity. The probe confirms that the drive doesn't fake its capacity. The announced size is 476.94 GB, matching what was reported earlier.

This is a good quality drive that is easy to install. This drive has enough storage capacity for my needs. Paired with the UGREEN enclosure; this gives me a portable high speed external drive compatible with my system.

While I don't have a great way to assess the speed since I don't have a drive utility, I can assure you that this drive is super quick. I use it for Steam games, and they load up significantly faster than a standard mechanical drive, but this KingSpec NVMe also loads even quicker than the Samsung (SATA) SSD is was replacing, and considering it's cost, it's just phenomenal! I've used it for a couple months now, so I feel comfortable confirming its reliability. Considering that it's only used for Steam games, that is saying a lot, because it's constantly being accessed, read, and written to.As with any NVMe, it's standard-sized and super easy to install, and for it's low cost, its absolutely a great contender or option for anyone that needs a faster drive, more space, or replacing an existing drive.

I am thoroughly impressed with this KingSpec PRIDE X400 2TB NVMe SSD. It has been a fantastic upgrade for my laptop, delivering top-tier performance at a very competitive price point. Installation was as simple as any M.2 drive, and it was recognized by my system without any issues.The performance is the real story here. I ran a CrystalDiskMark benchmark, and the results are outstanding. As you can see from my screenshot, I achieved sequential read speeds of 7029 MB/s and write speeds of 6399 MB/s. While advertised speeds are often best-case scenarios, getting results this close to the theoretical maximum in a real-world system is a sign of a high-quality drive and controller. In practical terms, this means lightning-fast boot times, incredibly quick game and application loading, and massive file transfers that complete in seconds.For anyone looking to make a significant and noticeable upgrade to their PC or laptop, this drive should be at the top of your list. The value proposition on the larger capacity models like this 1TB version and up is especially attractive. This drive delivers the speed, performance, and capacity of more expensive brands, making it an easy 5-star recommendation.
