WD sn550 nvme 1tb slow speeds

Had a adata su650 480gb sata SSD that I replaced with a WD Blue sn550 1tb nvme. 

Was expecting way better results speed wise than what I'm getting. Here are 2 pics one of each bench result. What could be the issue here. 

Top pic is the adata sata, bottom is the WD nvme

I might be wrong here, but when you use an NVMe as your boot drive, you'll never get the advertised speeds because of the constant I/O that windows does, so that is part of why your speeds aren't hitting advertised targets. The other reason, is that the SN550 doesn't have any DRAM, so sequential speed averages won't be as fast as say an SN750, or a 970 Pro. 

 

If you're using your computer primarily for games, and aren't doing huge sequential transfers all the time, SN550's or SATA SSD's are plenty fine. The difference between NVMe and SATA in regards to load times for games is barely measurably different. 

 

Where NVMe's and ones with DRAM really come into their own, is if you do photo/video production where you're routinely transferring 100+GB of data across drives/computers. And even then, if you're using an external SSD, you're still limited by the USB or Thunderbolt bus, so unless you're going NVMe to NVMe, you'll never even see the advertised speeds in actual use.

I've used a sn550 1tb nvme in a different build last year and it was hitting close to 2k in the bench while this one is less than half of that. 

Looking at Amazon customer review pics of the same drive my score is substantially worse.

Yeah that's what happened with mine and it's messed up. They need to change the description for the drives at amazon. I got a pre built that came with one of the good drives and I sent this one back a week ago
