HELP! Fast M.2 NVME Read Speed but Slow Writes

Recommended Posts

Posted · Original PosterOP

Hello guys,

 

I have a 1year old Sabrent 256GB Rocket NVMe PCIe M.2 2280 Internal SSD High Performance Solid State Drive (SB-ROCKET-256) that i bought from amazon, since I have a career in IT now i was doing some benchmarks on the SSD to see how fast it performed attached are the results. 

 

I see that the reads perfectly fine but it lags with the write speeds. Amazon post stated that i read and write up to 3100mbs which is the reason i bought it for,

 

Now my question is why is it writing so slowly?

 

I have a Lenovo Legion Y530 81fv i7-8750h with GTX 1050ti 16GB RAM

 

I made sure that the mobo was compatible and had a M.2 NVMe Capability. 

 

Windows still boots up super quick in under 5sec all programs in ssd are fine but when i try and copy and paste a copy of a 4gb file it starts at 68kbs YES kbs!

 

I need help if you guys got solutions let me know please!!!

I’m not sure why it’s this slow but you should not expect 3000MB/s writes.

According to their marketing material, the drive should be able to write at 1050MB/s.

The 3000MB/s write number is for the 4TB model (see attachment; image taken from Amazon.com).

Write speed, especially for the lower capacity is not going to be as good as 512gb  or more.

1050gb/s is the theoretical speed, normally you would get 1/2 of it.

Find out if trim is enabled. Or the companion software is installed.

If you replaced an existing SSD, make sure you're using the RAID mode in the BIOS and the NVMe driver in Windows. If you did not replace a SSD, and replaced a mechanical drive or a SATA SSD, you might need to install the NVME driver (Intel RSTe driver)

In addition to what others said - you won't get accurate results with only 1 GiB test on such high performance drives. The numbers won't get stable (e.g. initial use of cache) as the test finishes too quickly.

What?  Why on earth would you enable RAID in BIOS for a single SSD??


QUOTE ME IN A REPLY SO I CAN SEE THE NOTIFICATION!

When there is no danger of failure there is no pleasure in success.

Because that's what enables the Intel RST driver, like I've had to repeat in every thread where someone has said this.

 

That is literately what the OEM's do.
