Phison this week showcased its next-generation PS5026-E26 SSD platform with a PCIe 5.0 x4 interface aimed at high-performance desktops and enterprise applications. Based on the demonstration, the new drives will radically improve the sequential read and write performance.
Because of the PCIe 5.0 x4 interface that offers raw bandwidth of up to 15.8 GB/s in each direction, solid-state drives featuring this interface are projected to increase sequential read and write speeds of SSDs drastically. Other improvements include higher capacities thanks to new 3D NAND devices, enhanced reliability, and new features enabled by next-generation controllers.
Phison's reference SSD featuring its PS5026-E26 controller and 1TB of Micron's 3D TLC memory provides a maximum sequential read speed of up to 12,457 MB/s and a maximum sequential write speed of up to 10,023 MB/s (according to CrystalDiskMark), which by far exceeds capabilities of today's best SSDs. As for random performance, the drive can provide up to 1.31 million 4K read IOPS and up to 1.16 million 4K read IOPS, which is higher than the vast majority of client PCIe 4.0 x4 drives.
Phison's 1st Generation PCIe Gen5 E26 SSD controller is powered by Arm's Cortex-R5 cores accompanied by special-purpose accelerators from the company's CoXProcessor 2.0 family. The controller can work with all contemporary and future types of 3D NAND memory featuring ONFI 5.x and Toggle 5.x interfaces at up to 2400 MT/s data transfer speeds. Since Phison positions its PS5026-E26 both for client and enterprise usage, the controller also supports functionality like PCIe Dual Port connectivity for U.3 SSDs, single root input/output virtualization (SR-IOV), and zone namespaces (ZNS).
Phison did not reveal when the first client SSDs based on the PS5026-E26 controllers will be available commercially. However, last year it implied that the first drives using its PCIe 5.0 x4 platform would hit the market in the second half of 2022, which probably means late 2022. These SSDs should come to market in the same time frame as the Zen 4-powered AMD Ryzen 7000 processors.
The only thing that it did for me is increase price and lower the total drive capacity
Instead of chasing crap speeds they should focus on price and capacity because regular SSD are getting more and more attractive these days and those at 600mb/s :ROFLMAO:
excuse me for not giving 0 f about 1tb doing 10Gb/s when 4tb ssd 600mb/s is half price
You actually made me turn on PC and check speed of my ancient (6 years old this week!) SM951 ...
Rough speedup for this sample PCIe 5.0 drive in parentheses.
Unsure what's with low write at RAN4K Q32T16 for my drive, but let's disregard that (despite result being vwry repeatable).
Anyway, I agree that worst case vs best case isn't all that good... 20% read speedup (vs 600% sequential) and 250% write speedup (vs 9x sequential).
And I agree that probably moves something like Word startup from 2s to 1.8s.
But we have to keep our eyes on new tech/features, like DirectStorage and AMDs Smart Storage. So I will keep my judgment until some real world tests arrive, like game loading times, if there's any difference while playing, and so on.
I really just need 512GB, but I wouldn't mind 1TB. What I can say, there's no 4TB drives for half the price :p Where I live 1TB jumps roughly 2x in price for PCIe 4.0 drive vs 3.0. But a 4TB PCIe 3.0 NVMe drive is still almost 4x the price of that 1TB 4.0 drive ! So yeah, if 5.0 drives are another 2x increase vs 4.0 I'll skip. If it is roughly still just 2x vs 3.0 then it's a buy. After all, when I get one, I'm unlikely to upgrade next 6 years again ;D
Most software developers likely won't bother re-arranging their code to accommodate pervasively threaded and pipelined asynchronous loading beyond what is absolutely essential to user experience.
Try this: copy 1 x 1GB file and 1000 x 1MB file, despite the same overall size, 1000 x 1MB takes way longer. It only copies 1 file at a time (serial nature of I/O) and you will probably see 10-20MB/s speed...
As for rewrites - those will barely happen even in biggest of apps and suites, but I do expect future game development to take this into consideration (due to consoles supporting it already).
Also, you will slowly but surely stop using those options like "don't update in background while I play", so you will less often be forced to endure the whole "torture" cycle before starting to game. It's just all too often that I start PC that then needs an update, then start Steam that needs to update, then when it starts dozen games need to update, including one I want to play, and then you actually start a game, load the save and... time is up and you can shut it all down. Hopefully with background updates that will happen less, and when it does happen, should be faster. Letting stuff start and update/install at once on fast NVMe should improve experience quite a bit. Sure it's not something you do all day long, but boy does it feel like that sometimes ;D
