I have the following drives/controllers for sale. All are either new/open box or just used for some benchmarking tests. Paypal and US only. I will pay fedex expedited shipping. Everything is in excellent condition and I will gladly accept returns if needed. All items include best offer as well and can work a deal on bundles. PM me with any questions.

1. New Intel Optane P5800X 800GB-$1650 100%

2. Like new Intel Optane P5800X 800GB-$1550 100%

3. Like new Dell branded 6.4TB NVME gen4 ssd (this is actually a samsung pm1735 u.2 drive made for dell). I have 2 of these and am asking $1500 each 100% SOLD

4. Highpoint SSD7505 NVME HW RAID controller with 4 x 1TB WD_Black SN850 - $900 100%

5. Highpoint SSD7505 NVME HW RAID controller with 4 x 1TB PNY XLR8 CS3140 - $800 99%

6. Gigabyte GC-4XM2G4 Aorus Gen4 AIC adaptor. I have 2 of these and am asking $75 each


The optanes are the best all round drives today. The dell/samsung pm1735s are the fastest large capacity u.2 enterprise drives. The highpoint hw-based NVME RAID controllers were the highest performing combo that we have measured to date. When using both of the controllers in what they term, cross-sync, we were able to get over 300Gbps in both read and write. This was with a system that included a single amd epyc 7452 cpu and using both ms windows and linux. We could probably get a bit better performance if we used the 2TB m.2 drives. The company advertises 200Gbps for a single controller and 320Gbps with 2 in cross-sync mode.
Thanks for looking!

I know you meant 300GBps because 300Gbps would be really slow. :D
300 Gbps is actually pretty fast - thats 37.5 Gigabytes per second - 300 GBps would be insane.

Also pcie 4 x1 lane=2 GB/s - so unlikely you would ever get 300 GB/s :) - unless you did a RAID over 10 pcie4 x16 ports and then I think you would become bottlenecked by memory speeds anyway.

Not sure if you were joking or not but 300Gbps is extremely fast and you probably won't find any benchmark (at least on these forums) that comes close. I posted a thread in both the truenas forum and raid forum with some details. As Bjorn mentioned, the pcie 4.0 spec has some physical limitations which this card was close to hitting. Most of my projects were focused on achieving max throughput for the NIC cards. With dual port 100GE NICs, they would saturate a pcie gen3 slot even at x16. When the amd epyc rome cpus came out, we were able to start leveraging pcie gen4. pcie gen3 slots were usually not the bottleneck for storage but in the case of these hw nvme controllers, we needed the pcie gen4 platform to maximize the performance. (and if you were serious, you need to add $10 onto your purchase price:p)
