Phison Showcases 12 GB/s Speeds for PCIe 5.0 SSDs Through Its New E26 Controller
Phison has showcased the expected performance of its upcoming PS5026-E26 controller, built to usher NVMe SSDs into the PCIe 5.0 realm. The company showcased its new controller's prowess by building a reference SSD design based on 1 TB of Micron's TLC NAND. Phison's new controller has been built from the ground-up to accelerate next-generation SSD workloads - including direct access technologies based on Microsoft's DirectStorage API, accelerated by two ARM Cortex-R5 cores and three proprietary CoXProcessor 2.0 accelerators built on TSMC's 12 nm process.
Phison's internal testing shows its reference SSD achieving sequential read speeds of over 12 GB/s in CrystalDiskMark, with sequential writes going as high as 10 GB/s - a 70% performance increase compared to the world's fastest PCIe 4.0 SSDs, which currently top out at around 7 GB/s sequential speeds. As to 4K performance, one of the most tangible metrics for user experience, random reads are set at around 16.000 IOPS, showcasing room for improvement with further firmware optimizations for actual shipping products.
Interestingly, Phison opted for the M.2 2580 form-factor for its proof-of-concept SSD, which features a slightly wider PCB and connector footprint that's not backwards compatible with M.2 2280 slots. Expect SSDs based on Phison's PS5026-E26 controller to hit the market later this year - closer to AMD's release of its 600-series chipsets for its next-generation AM5 platform.

Intel Optane will still be the performance king for years to come.
-Optane 905p user, from then until it goes bad, which might take a while, since it's rated at multiple dozen times higher endurance than your avg drive

if so that is really sad...
hothardware.com/reviews/kingston-dc1000m-data-center-ssd-review?page=3That's probably true. Dynamic RAM has the same issue, although on a different scale: true random access still takes about 60 ns, which is a modest improvement since DRAM was invented. Ways to get around this problem are similar, too - more parallelization, more queueing (DRAM controllers do that), larger caches, more levels of cache. And optimization of software to use random access less often.
I've never heard of these so im guessing these attempts were canned when Optane was pushed to the sidelines?
It's sad really because we have the tech to push for nearly unlimited endurance and randoms/low latency courtesy of Optane but Intel in their infinite wisdom decided to keep it proprietary and there it died. With economies of scale and opening it up to AIB's at least the cost could have been brought down while allowing them to keep making Optane themselves.
