Dell XPS 15 9560 1TB PCIe SSD

just bought a new Dell XPS 15 9560 that came with a 1TB PCIe SSD.
SK HYNIX PC300 M.2 2280 1TB.
I thought they came with Samsung PM961?
What the performance differance? And is one better than the other?

 

They put good ones in the 1st few mainly for reviews and the microshaft store seemed to get a lot, now it is whatever is cheapest and no they wont change it.
I am sure you can google benchmarks to see the difference.

 

So would you consider the Hynix JUNK.?
Is the laptop worth keeping? I’m comparing it and the HP Spector 360

 

Hynix isn't necessarily bad since they are a major supplier of DRAM, flash, HMB2 etc. Run CrystalDiskMark and see what read/write speeds you are getting.

 

No it's just fine. No one would know the difference between the Hynix NVMe drive and the PM961. Trust me, I've owned both.

 

I did keep one, you can google them to compare speeds, make up your own mind after that

 

I doubt you would notice any real world difference, regardless of what benchmarks tell you

 

This is spot on. Trust me, I'm all about benching and having some fast stuff but it was 100% the same with daily use even with demanding loads...

 

@custom90gt @antik - Agreed

I ran PM961 (nvme 2nd gen) and 850EVO (older SATA) SSDs in two XPS laptops (9550 & 9560).

- From a daily use perspective, I noticed no difference although startup was probably a second or two faster with the 850EVO

- Running huge virtual instruments (40GB+ pianos) at ultra-low latency I saw no difference between the SSDs (or the laptops for that matter). This software puts huge stress on the SSDs as there is not enough RAM to store 40GB+ of samples and I push the CPU to the absolute limit. I can measure the results, hear dropouts, and feel lags so this is a decent test.

- nvme benchmarks are better, sometimes much better. My bet is a few specialized programs can benefit from the newest nvme drives. Also, some nvme benefits are reduced by compromises required in a laptop.

I checked out the HP Spectre360 yesterday. Screen, finish, and form factor are really nice. Speakers were terrible. The specs are much different from those of the XPS as GoNzo notes.

 

Try the Samsung NVMe drivers 2.3 in @GoNz0 signature. Stock MSFT driver was super slow on write and after installing Samsung's driver write speeds are awesome. Stock driver on PM951 gave me 1.4GB/s reads and 154MB/s for writes. Heck 850 EVO m.2 was faster. Now, reads are 1.5 GB/s and writes are 310MB/s.
On linux I get 1.6GB/s reads and 174-180MB/s on stock nvme driver.
