Will Adata SX8200 m.2 Bottleneck on PCIE 2.0 x2/x4?

I was planning on buying  the Adata SX8200 but i found out that my Sager Laptop only supports pcie gen 2 x2 and x4. I already populated the 1st slot with a Samsung 850 evo m.2 probably running at x4. So if i connect another one itll both run on pcie 2.0 x2 speeds

 

Would it still be worth it if i bought the Adata 480gb m.2 or should i just go with WD Blue m.2?

 

Also how hot does these two m.2 drives get?

i doubt that a drive can bottleneck pcie but i could be wrong. check online for pcie bandwith and compare to max read/write speeds.

850 evo runs SATA, not PCIe lanes, so the SX8200 should get x4 if you get it into the correct slot.

 

From userbenchmark, it seems like the SX8200 doesnt go past the 2GB/s limit of PCIe 2.0 x4 in all but sequential reads, so I'd say you shouldn't notice any performance difference.

The Samsung 850 EVO is a SATA device. It would not be pulling x4 PCIe lanes. Usually, there is a switch between the SATA ports and PCIe lanes for those slots and it will alternate between using either or if SATA or NVMe devices are used. The ADATA XPG SX8200 operates at up to 3.2GB/s read and 1.7GB/s write on a PCIe 3.0 x4 connection. Since it operates at PCIe 2.0 speeds, the SX8200 will be limited/bottlenecked to 1.6GB/s read/write if operating with x4 lanes or ~800MB/s if operating with just x2 lanes. For the price, the SX8200 is a great buy and it doesn't get too hot if not operating at full speed, even then, it has decent power/thermal management.

There's an m.2 version of samsung 850 evo but it's the same speed as the sata version. And Im using it as boot drive

Yes, SATA is the interface for both the M.2 and 2.5" 7mm form factors and they both operate at the same performance level.

Does that mean I would still get PCIE 2.0 x4 speeds even if both m.2 slots are populated because the 860 evo would use SATA interface?

 

If thats the case then it would still be worth it?

Possibly. I don’t have any info from the manufacturer to read about the storage options they provide.
