PCIe and speed, CPU and PCH or chipset lanes questions

[Cristu]

I'm aware there are the so called "CPU lanes" and the "PCH" or '"chipset lanes". But where exactly are they? The x16 slots are always the CPU lanes and the rest are PCH lanes? Or a PCH lane will become a CPU one if your CPU supports?

 

I'm asking that because I'm getting myself a new rig and I wanna try and run 2 adatas sx8200 in raid 0 because yes. However, it's said that even one of those will saturate a PCH x4 lane, but a CPU x4. I still haven't chosen the CPU and here hoping intel's 9th gen will have the CPU I need for this or maybe should I try it on ryzen 2700x 20 lanes?

Those are horrible SSDs, don't waste your money on them.

If you want the fastest possible speed then get a 905P.

What makes you say the SX 8200 are bad SSD's? I have one and it does just fine.

Why you say they're horrible? 

 

I would go for something like a 905p if I had the cash, haha, but I'm rather looking for something very cost/benefit. I'm actually planning raid 0 with small, 250gb ssds. Nothing too fancy, haha.

Reviews, and also it's a budget SSD, not a good quality one from a brand like samsung or intel.

 

I wouldn't consider raid 0 "benefit" more like "waste of time" and "no noticeable performance difference"

Much higher chance of losing your data too.

 

A regular sata SSD is more than enough speed, if you're doing video editing or data analysis or something like that as your daily job then get a samsung NVME SSD.

Or just get a 500gb ssd.....

Let's ignore HEDT platform like X299 ans X399 for the moment, and use Ryzen and Coffee Lake as example

 

If you have a graphics card, it instantly pulls 16 CPU lanes regardless of what SSD and how many of them you have.

 

If you're on Ryzen, there will be another 4 lanes on the CPU for a PCIe SSD. On Intel, you dont.

 

That's when chipset lanes come in. To PCIe devices, chipset lanes = PCIe lanes. On Ryzen they are PCIe 2.0, on Intel they are PCIe 3.0

 

However to the chipset, everything connected to it gets a combined bandwidth of PCIe 3.0 x4. In other words, when multiple things connected to the chipset are being used at the same time, they slow down.

Would you suggest I get a ryzen 2700x if nothing better comes from intel 9th gen and use a single samsung 970 on the x4 cpu lanes?

If you can afford the 9900K then it will be better than the 8700k or 2700x.

 

And yes, use a single 970 as your storage, it's one of the best consumer SSDs on the market.

Reviews? Check out the reviews for yourself. It is highly rated, by myself included. The SX8200 is one of the best drives in the market right now. They are great quality and work wonderfully. It is the best buy right now. Nothing beats it for the price. At 500GB the SX8200 is $110 vs $150 for the Samsung 970 EVO...

 

I agree, RAID 0 is useless for most consumers. Just get a 1TB class drive instead of two 500GB drives. 

 

I use 3 NVMe SSDs in my z370 rig and a gfx card, and thunderbolt card installed, no issues. Z390 will handle what you want.

lol

 

 

The 970 pro is better than the 960 pro btw.

 

Also the 970 doesn't even compare to an optane drive like the 800 or 900p.

What does that prove? Synthetics are simply synthetic and do not represent real-world use patterns or application workloads, not those numbers you quoted, besides the write workload at least. How often are you going to write multiple 100GB+? 

 

The 500GB model has 142GB of write cache and the 960GB model has over 270GB before it fills and degrades to its native write speed. And, once it does and the file transfer finishes, it actually recovers fairly quick compared to many other drives I've tested. 

 

Check the performance results compared to the BPX Pro.

See how well it scores in PCMark 8 and SYSmark and loading games compared to the other drives?

 

See how fast it copies my 50GB file folder vs the other drives?

 

The ADATA XPG SX8200 is a top pick. It offers more endurance than the Samsung 970 EVO and similar performance for almost 30% cheaper. There's nothing horrible here. Check out the QD1 random read performance...that should say it all. 80-90% of the time QD1 is what matters for consumer workloads.
