Silicon Motion Launches Power Efficient PCIe Gen 5 SSD Controller
Silicon Motion Technology Corporation, a global leader in designing and marketing NAND flash controllers for solid-state storage devices, today announced SM2508, the best power efficiency PCIe Gen 5 NVMe 2.0 client SSD controller for AI PCs and gaming consoles. It's the world's first PCIe Gen 5 client SSD controller using TSMC's 6 nm EUV process, offering a 50% reduction in power consumption compared to competitive offerings in the 12 nm process. With less than 7 W power consumption for the entire SSD, it delivers 1.7x better power efficiency than PCIe Gen 4 SSDs and up to 70% better than current competitive PCIe Gen 5 offerings on the market. Silicon Motion will be showcasing its SM2508 based SSD design and other innovations during the Future of Memory and Storage event from Aug. 6 to 8 at booth #315:
Silicon Motion's SM2508 is a superior-performance, low-power PCIe Gen 5 x4 NVMe 2.0 SSD controller designed for AI-capable PC notebooks. It supports eight NAND channels with up to 3,600 MT/s per channel, delivering sequential performance speeds of up to 14.5 GB/s and 13.6 GB/s and random performance speeds of up to 2.5M IOPS, providing up to 2x higher performance than PCIe Gen 4 products. The SM2508 maximizes PCIe Gen 5 performance with an impressive power consumption of approximately 3 W. It features Silicon Motion's proprietary 8th-generation NANDXtend technology, which includes an on-disk training algorithm designed to reduce ECC timing. This enhancement boosts performance and maximizes power efficiency while ensuring compatibility with the latest 3D TLC/QLC NAND technologies, enabling higher data density and meeting the evolving demands of next-generation AI PCs.
Besides the SM2508, the Silicon Motion exhibit will also include:
MonTitan PCIe Gen 5 Enterprise SSD Development Platform for AI Storage Workloads

But my question is when will Samsung and Western Digital release pcie5.0 designs?
A 2TB PCIe 5.0 drive is still some $70 more expensive than a 4.0 drive and I'd except a product using this 6nm NAND to increase that margin a bit more.
Most customers won't see any benefit from going PCIe 5.0. Margin of error difference in games and common apps.
Perhaps the release of this SM controller will push WD/Sammy to proceed asap :D
I don't care about seq speeds. While maintining <=7W TDP, make that controller do at least 150 MB/s Q1D1 R/W and take my money.
Things like these should be eliminated forever:
Samsung also handled it very poorly. Given the scope of the issue, the firmware fix took ages. There was zero communication and when they finally released the fix, they never addressed the root cause or if the drives really suffered irreversible damage.
Well, actually their silence speaks louder than words. Of course, the damage is/was irreversible or otherwise why would they not alleviate customer concerns about their degraded drives?
The most popular theory from tech-savvy folks is: Samsung's botched firmware shredded the NAND on the drives due to buggy write amplification.
It is kind of unfathomable that Samsung screwed up this badly AGAIN after they already had several firmware fiascos with the 980 Pro (including bricked drives).
So, I'm very happy to hear about this SM controller and hope it finds widespread adoption. Phison surely are not sleeping so I'm sure they will have a 6nm part soon as well. The more alternatives to crap like Samsung, the better. I would really love a new blazing fast Gen 5 Crucial T800 (would almost buy for product name alone :D ) with a more efficient (cooler) SM or Phison controller.
