Single Slot PCIE Storage hits 24 GB/sec

[Staggeredsix_Mark]

Liqid LQD 4500 Honey Badger. 24gbps is different than 24GB/sec... I would say its more like 28.8 GB/sec seq read. 

 

The article describes Liqid's Gen4 storage solution that runs at 16x. Under the hood is 8 Phison E16 based modules running through a Gen4 PCIE switch. The solution can be configured in JOBF or RAID, depending on the use case. It's also massive. FHFL. It can run in a full size workstation for workloads that require ultra high bandwidth. It was presented by Liqid and Phison at FMS 2019. I was the presenter for that entire show! If you have questions, go ahead and message me.

 

For you enterprise nerds :

Fancy, but I wonder how long it lasts.  An unbreakable raid seems great for durability

It's not in a RAID, the endurance depends on the use case.

Liqid is presumably doing on-card NVMe RAID here, similar to what we've seen in some PCIe 3.0 x16 cards in the last couple of years

Longevity does definitely depend on use case, and I don't think it would be that long in an enterprise use case.  Maybe as a type of cache drive for video editing or the such?

 

Edit: I didn't realize that you worked for them lol.  Also, you might want to add some quotes and stuff to the OP

Cool a DDR4 benchmark of the onboard DRAM. We all know TLC flash isnt that fast.

until the OP is updated properly as per the posting guidelines, this topic has been moved.

once updated properly, report the thread and it'll be moved back as it should meet posting criteria.

Here is my FIO job file I use. YES I understand it can be done in multiple ways. There are reasons I have the file written like this. I can target specific nvme devices to do things.

Unless you need insane sequential transfers, it pretty much doesn't matter whether you're on a single high end SATA SSD or 24GB/s NVMe drive array. Especially when you realize there are literally still people who use only HDD's. But yea, it's nice to see speeds go to insane levels. Can't wait the day when RAM and storage will have identical speed which will be matched with L whatever caches in CPU's. That's gonna be pretty sweet when it happens.

Well it does 4 million IOPS and 10GB/sec random reads at 4k/32. Not too shabby
