That may seem an outrageous insult by TeamGroup to one's intelligence but I've gotten very similar "information" from Samsung, Western Digital, etc.the date on the driver is in device manager under storage controllers version 1. That may seem an outrageous insult by TeamGroup to one's intelligence but I've gotten very similar "information" from Samsung, Western Digital, Xenon 775 The speed of the SSD will be reduced due to the reduction of the remaining capacity. On the other hand, if the SSD is on background running (i.e Garbage collection, wear leveling, Read retry.ect.) during the test ,it will also shortly affect the speed of SSD.Īccording to the picture which you provided, the first time has used 23% of the capacity, the second time has used 37% of the capacity. This will shortly affect the speed of SSD. When the computer is overloading or there are too much data saved in the SSD, the computer may take more time to process multiple tasks and data transfer. Normally, the test of the SSD performance is must be conducted when the SSD is completely empty to ensure that the test is accurate. Thank you for contacting TeamGroup customer service center. A billion GB/s does me no good if it has to stay empty to do that) I don't use drives empty so I really could not care less what its "empty" speed is. The drive should be tested for speed freshly formatted (empty), they say. Not only that, once it had some data, I put even more data on it.
(Their bottom line being that I had done an apparently foolish thing, namely installed it in a computer and put data on it. 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.
