Review  Toshiba BG4 M.2 NVMe SSD Review: One Tiny, But Speedy SSD

With performance that is 6 times that of any SATA SSD...
Perhaps "up to six times" would be a slightly more accurate way to word that? In most real-world tasks, you are not going to see that kind of performance difference. In the game load test, it was just 8% faster than an MX500, which would be more or less unnoticeable. It fares better in some other tests, particularly synthetics, but I'm struggling to find charts showing it performing 6 times as well, and it actually performs worse in a few due to the increased latency from lacking an onboard DRAM cache. Even the sequential read and write numbers are only around 4 times those of a good SATA SSD, so I'm not sure where that number came from.

Also, while the power consumption appears good in the file copy tests, the idle efficiency is a bit below average. And being DRAM-less, that also leaves me wondering whether there might be increased power draw on other parts of the system, like the system RAM or CPU, if those are getting utilized more, though that would probably be difficult to accurately test.

The 6 was a mistype, meant 4 as you stated. I'll get that fixed.
