As we head into Flash Memory Summit 2023 season, DapuStor has a new PCIe Gen5 NVMe SSD in mass production. This SSD is powered by a Marvell controller that has a special place in STH history. The new SSDs are capable of up to 14GB/s reads and 8GB/s writes making them a new performance option for the server industry.
DapuStor Haishen5 H5100 PCIe Gen5 NVMe SSD with Marvell Bravera in Production
The new DapuStor Haishen5 H5100 SSD offers capacities from 3.2TB to 15.36TB. Even 1TB and 2TB capacities are now being passed over in favor of higher capacities per drive.
Performance is very good at over 2.8M 4K random read IOPS and 600K on the write side. There is a trend with modern SSDs to focus more on the read side. As capacities increase, SSDs are pushing into new territories often serviced by disks in previous generations. Perhaps more simply, with a 16TB class SSD, there is going to be more content stored on the drives for longer periods of time. A great example would be a CDN or video caching node where a video is written and then read multiple times. That type of access greatly reduces write pressure on a drive and was something that hard drives have done for many years. Now, that can be serviced at higher density with SSDs.
Aside from the Kioxia NANDÂ The controller on the drive is a Marvell Bravera SC5. Here is a quick slide with the basic SC5 specs.
A fun fact about the Marvell Bravera SC5 that this is based on. If you saw our Marvell Bravera SC5 launch piece, you will have noticed that STH provided feedback on the original name for the controller and Marvell changed the name just before the launch.
Still, it seems like DapuStor is garnering performance near the edge of the controller’s performance specifications and exceeding it in the 4K RR IOPS side.
Final Words
If you have not heard of DapuStor, they are a newer vendor focusing on higher-performing SSDs. We are going to have our first DapuStor SSD review later this week so stay tuned. Our readers can also get ready for next week when we have a massive amount of news around the SSD space as we head into Flash Memory Summit week.
