Samsung 980 1TB SSD sloooow speed!!!

Go to solution Solved by Kilrah,

That system only supports PCIe 2.0 x2 to the m.2, so it'll be 4x slower than the standard PCIe 3.0 x4.

 

4th gen is basically when m.2 was first indroduced and there were essentially no drives available to use it with you could buy.

EDIT:

Thanks to members, i found that outdated Mainboard, made a huge bottleneck and cause this performance problem.

Thanks all.

Hello everyone,

Today i purchased Samsung 980 1TB drive for increased performance and storage space, nevertheless i faced something weird!!! Benchmark results are way slower from advertised speed, ~800MB/s write/ read speed as show in screenshots below, also double checked if connected properly to the slot.

 

any recommendation or something from you guys?

Double checked if connected correctly to the slot.

outdated hardware, or problem with this SSD?

  • Mainboard : Asus Z97 Pro gamer
  • CPU :           4790K
  • Ram:            16GB G.skill trident
  • SSD:             Samsung 980 1TB  -   NVMe M.2

As you see in screenshots, SSD is almost free and only 5% of capacity is full

Also, FWIW, the 980 is not the speediest drive even when you have PCIe 3.0 x4 available to you. It exclusively relies on HMB instead of a dedicated DRAM cache, which can significantly slow down the drive with very large or sustained writes. It's fine for casual use, but if you push it, speeds will drop through the floor.

 

It's odd that Samsung named their most entry level PCIe 3.0 drive the 980 and their top of the line, industry best PCIe 4.0 drive the 980 Pro. They share virtually nothing in common but the "980". That drive is easily bested by even a 970 Evo from Samsung.

Thanks dude, You're right,

Due to manipulated hardware market in here, price of Sata Evo860 is same as m2 980 SSD Drive both in 1TB capacity, So i just checked if mainboard support m.2 and just made this purchase, and didn't paid too much into the details, although my mainboard does not support full potential performance, but it was a win choice😄.

Marketing trick 😄,

but for me, mainboard made a huge bottleneck on both read/ write performance... Time for an upgrade...
