Extremely slowOptions
04-07-2019 04:09 PM I am trying to figure out why my SSD's are running so slow (I purchased two 500gb Extreme SSD's). Connected to both USB-C and USB-A 3.1 ports on an Asus Rog Strix X470-F motherboard, both types of 3.1 ports are listing the following speeds on CrystalDiskMark 6.0.2 x64:
Read:44.40MB/s Write:43.60MB/s
These are nowhere near the advertised *Up to* 500MB/s
Is there a firmware update or something that I am missing. I truly don't understand how they can be running so slow. Any help would be greatly appreciated.

I think SanDisk's problems are too little that posts here just get's ignored. If not for the water resistance, I would have just bought an M.2 drive and put it in an enclosure.

05-02-2019 12:05 AM Is that the speed you are getting from yours? Something is definitely wrong with mine if that is the case. I can't believe I've never gotten a response from Sandisk either. Lesson learned for me I guess. Re: Extremely slowOptions
06-02-2019 11:21 PM Hi there, I have basically the same issue with speed, it's too low! How can I fix it?
thanks,

07-02-2019 09:17 AM Are you using the included USB-C to USB-A 3.0 cable? When I use the included cable I achieve the advertised speed.
When I use another USB-C to USB-A (likely 2.0) cable I do not. I think that may be your issue. Re: Extremely slowOptions
09-13-2019 07:33 PM I have an older laptop with three USB ports. Two are USB 2.0 and one is a powered USB 3.0. This drive performs slow in the USB 2.0 ports (similar to the posts below) with R/W speeds just over 40 mb/s - nowhere near the advertised rate of up to 500.
When I plug it into the USB 3.0 powered port, however, viola. Not quite 500, but I'll take a sequential R/W 400 Mb/s on an old machine..
