KIOXIAEXCERIA PLUS NVMe 500GB PCIe 3.0 Gen3x4 M.2 2280 SSD, LRD10Z500GG8

I bought this as a replacement for the Toshiba TR-200 that I have been using for a couple of years, and did an outstanding job. By reading the Kioxia blurb I was under the impression this was a continuation of the TR-200 range under the Kioxia name, but alas this SDD, behaves quite differently. It has about 20% less throughput than the Toshiba predecessor but is 40 to 60 % faster on random reads.Since I am using this in a personal computer rather than a server, this is fine, a noticeable improvement in fact and combined with the very keen price on the 480GB part, I am overall very happy.

Went for one of these having used a Toshiba drive for a number of years, assuming this model would be an improvement. Benchmarking was interesting, with sequential performance being a bit worse, especially surprising with reads sometimes in the 300's of MB/s. The much slower 4K tests actually rated higher though, so maybe some performance compromises have been made to improve file access.This would seem to be confirmed by the biggest difference coming in the access time test, where read and write are similar. Normally write access time is much less than read, so in the case of the Kioxia it can access to read a file a bit quicker but take a bit longer to write access. Maybe as a system drive this could be beneficial where lots of individual files are accessed?Running the compression benchmark in ASSSD produced a very inconsistent graph, when compared to the Toshiba (which is MLC flash, not the TLC on this) with read gradually increasing and write dropping down badly in between good performance. For that reason I'll stick with the older drive as a system drive and use this one for additional storage, for which it is a good value solution, so long as it lasts well. I am not too sure about that though, because this has "made in China" written on it. Experience tells me that it may fall short on quality control of components and manufacturing processes.

What i like:* at time of purchase (Dec 2020) it was the cheapest 250gb~ drive in stock* Great build - sometimes you get a nice brand name one which is made of rather flimsy plastic8 Excellent performance when used with SATA connection and USB 3 5Gbps dongle* mainly used for testing of Linux distributions and cant complain with performanceWhat i dislike:*nothing - its been greatGreat performing SSD. The brand was formerly Toshiba Memory Corporation, which was why i went for this brand over the others, as well as it being the cheapest in the capacity of range of 240/256GB.

The Kioxia EXCERIA 480 GB 2.5 Inch SSD isn't going to compete with the more expensive brands, you do get what you pay for in terms of speed and efficiency, but for £40 at time of writing, this makes an excellent additional external storage solution for the Xbox Series X.The read/write speed is below that of my Sandisk drives but only slightly and for running Xbox One games on my Series X (you can't run Series X native games from it, sadly) it's a lot faster than a mechanical USB drive if you use a USB 3 enclosure for it. It also needs to be allocated before formatting if you're going to use it on a PC, so you'll need to use Disk Manager (just type Disk Manager in the search box on Windows) to allocate the drive then format.

I bought this Kioxia Exceria 240GB SATA SSD to replace the OEM 7200rpm HDD in a new / old stock Lenovo ThinkCentre M72e Tiny PC from 2012, which only has a SATA II interface. Still, I hoped that I'd see some performance improvment from the SSD, even though it would be limited to SATA II transfer rates.The drive is solidly built, with a tightly-manufactured pressed-metal casing rather than the plastic often found on budget (and even some mid-range) devices. It looks and feels like a quality product, which is impressive considering the price. Fitting it was easy, as it's a perfect drop-in replacement for a 2.5" HDD. Upon booting up, it was immediately recognised by the BIOS. Installation of the Ubuntu Mate 20.04 LTS operating system was brisk and trouble-free, confirming backwards compatibility with SATA II.So, has it improved the performance? Yes, it has... significantly! It has transformed a modest-spec, nine-year-old PC into a surprisingly zippy little machine (and a somewhat quieter one, too) that's perfect for web-browsing, watching YouTube, editing documents and spreadsheets, and programming. I can't verify Kioxia's performance claims due to the PC's SATA II interface limitations, but I can say it's a darned sight faster than the old 7200rpm HDD. Time will tell whether it's reliable, but given the obvious quality of manufacture externally, I'm quite hopeful.I'm sure there are better choices for those with a considerably larger budget, but all I wanted was a decent, inexpensive SSD to perk up my older-specification PC. This Kioxia Exceria seems well-respected, and does the job nicely at a very pocket-friendly price.
