Question Corsair MP600 1TB drive speeds on PCIe 3.0 or alternative to Samsung drives

[Deleted member 2783327]

I have recently found my Samsung drives to be under-performing. Of course, Magician software says they are working at about 60% - 70% of advertised max speeds, but other software I've used to test (including AS SSD Benchmark), shows the drives are not where I would expect them to be performance wise. 4K random speeds down as low as 25MB/s

I have no AMD, but am not against going AMD, it's just that where I live AMD is 3 - 4 times the price of Intel. I mention this because AMD is currently the only place a PCIe 4.0 SSD can be used optimally. I note that the Corsair MP600 is backwards compatible, as I expect all PCIe 4.0 SSDs will be.

I've been paying a premium price for Samsung drives and none of them are anywhere near TBW limits, or greater than 40% full. The Systems are not over heating, so I don't think the drives are throttling.

So I'm considering jumping ship. Support from Samsung has been pretty poor which is pushing me towards other brands. I have 20 Samsung SSDs ranging from 960 EVO 250gb to 970 Pro 1TB.

So; the question; how do PCIe4.0 drives perform on PCIe3.0 systems? Can I expect as good or better than Samsungs results. (My 970 Pro 1TB boot drive which is on CPU maxes out at about 1800 MB/s, where as the other two are 2200MB/s - 2300 MB/s - One on CPU, one on chip set).

I saw the Corsair on a review site, but I'm not fixed on Corsair.

I figure the PCIe4.0 drive will also better position me for when Intel eventually supports PCIe4.0 or AMD drops their prices (Won't hold me breath for either of those).

I see a lot of posts here about poor performance. I wonder if perhaps there is no solution , or if perhaps might be other factors, such as motherboard (though I have 7 different motherboards and results are the same across all).

I welcome recommendations and advice.

Where are you that AMD prices are 3x-4x that of intel?

The Corsair Drive will perform fine at 3.0 speeds i'm using this drive in 4.0 mode and there are no performance issues.

TL;dr AMD CPU's are very expensive here. Intel doesn't even come close in the HEDT sector.

Ignoring core counts;

CPU
Intel top of the line: https://www.pccasegear.com/products/48449/intel-core-i9-10980xe-extreme-edition-processor
AMD Top of the line: https://www.pccasegear.com/products/49292/amd-ryzen-threadripper-3990x-processor

Intel 10940x: https://www.pccasegear.com/products/48448/intel-core-i9-10940x-processor (I actually paid $1399)
AMD 3970x: https://www.pccasegear.com/products/48565/amd-ryzen-threadripper-3970x-processor

Motherboard
AMD: https://www.pccasegear.com/products/48680/msi-creator-trx40-motherboard
Intel: https://www.pccasegear.com/products/48668/msi-creator-x299-motherboard

10940x + X299 Creator = A$1399+ A$889 = A$2288
3970x + TRX40 Creator = A$3449 + A$1449 = A$4898

My RAM was also QVL'd for the Intel board, but we don't know if it would have worked in the AMD system. I had a kit I was considering which was $739 up until a month ago. Now $589: https://cplonline.com.au/memory/des...-32gtzn-tz-neo-32g-kit-4x8g-ddr4-3600mhz.html

So, all up, I was looking at A$5637. Hmmm... I probably should have said "3 - 4 times to convert Intel to AMD". This is for middle of the road.

For top end; Intel: A$889 + A$1999 =A$2888
AMD: A$1449 = A$6799 +A$739 = A$8997 (3.112x Intel).

Those prices would be insanely worse if I bought from Amazon AU or eBay.

Of course, there were other potential costs: A beefier cooler (360mm instead of 240mm AIO). Additional fans and/or better case. Increase of about A$600 per year in electricity costs. LAN here is all 10G hence the selection of motherboard. I only use HEDT as mainstream systems only have 16 PCIe lanes (or maybe 16+4). Either way, even a 28 lane CPU is not enough for 3 or my systems.

Anyway, glad to hear the Corsair works. I did see a couple of posts here that didn't sound very promising about slow speeds. A 1TB 970 Pro here is A$550. I believe they are about USD $200? So, if I pay premium price I felt I should be getting good to premium performance. I'm not, so perhaps it's time to try out some other brands.

Would you mind bench marking the speeds with AS SSD Benchmark and posting the results?
