result or a diagnostic app of their own to show it has actual bad electronics.įor example, take this email I got back from TeamGroup support regarding a 2 month old NVMe SSD drive that had dropped from 1,800 MB/s (Sequential read) to 300 MB/s (yes, that's no typo): 99% of manufacturers will refuse to replace the drive if the only issue is its speed. Regarding your SSD speeds, after years of experience with them, I can tell you that you pretty well "get what you get". In Device Manager what is the date on that driver? In my original post in 2016 (this thread) I suspected the driver was already showing serious signs of being abandoned. I increased the total RAM to 16GB, and started exclusively using SSD drives (except for an external drive used for storage) in it so the speed is not an Xenon 775 I still have the motherboard I mentioned in a system and it works like brand new so there's been no real need to replace it. As per my original post, I did indeed find a newer version and tried it but stuck with it only because it worked as well as being newer.Īt that point, I had dedicated about all the work I cared to spend on that issue. If you have a version that actually works, I'd stick with it.
Same with the Marvell driver, in my opinion. The reason is that the driver works just fine and no further modifications to it have been necessary. It being Jan 2021, a newer version would be expected.
Updates to the driver usually address support for a slightly modified chip.įor example, if you look in Device Manager at the standard Microsoft-supplied "Disk drives" driver, it's from. One always hopes that newer drive controller drivers will increase the drive speed a little. WHQLĪccording to the file version number, it is numbered higher so naturally it should be a newer version However, as I mentioned, finding this driver isn't easy and I ran across several that, no matter the date or version number, simply wouldn't work. Marvell MV-91xx/92xx SATA 6G Controller Version 1. The latest driver I can find is marvell_mv91xx_1.
