Intel Showcases Alder Lake System With PCIe 5.0 Solid State Drive At Nearly 14GB / s

What just happened? Just as more and more people are buying PCIe 4.0 SSDs, the next generation of PCIe 5.0 storage devices is gaining popularity. The latest announcement was made by Intel’s chief performance strategist and former tech journalist Ryan Schrout, who showcased a Samsung PCIe Gen 5 SSD running on an Alder Lake system and showing impressive speeds.

Schrout tweeted that the PCIe 5.0 / Alder Lake demo was supposed to be part of Intel’s CES 2022 lineup, but with Chipzilla joining many others announcing that it will somewhat limit its physical presence at the show and will be mostly virtual, we must see the SSD in action a week earlier.

The Shrout system consists of a 12th Gen Intel Core i9-12900K (Alder Lake), an Asus Z690 motherboard, and an EVGA RTX 3080 graphics card. This is a pretty standard high-performance setup apart from the Samsung PM1743 PCIe 5.0 SSD. Gen 5 SSD is an enterprise-class drive, which means the final consumer model will look different.

The demo begins by confirming the speed of the top SSD WD Black PCIe 4.0, which reaches almost 7 GB / s. That’s fast by any standard, but a Samsung 5th gen SSD connected via a PCIe 5.0 adapter card nearly doubles the speed of a 4th gen drive, reaching roughly 13.8GB / s.

In addition to these speeds, Samsung says the PM1743 has about 30% better power efficiency (608 MB / s per watt) than PCIe 4.0 drives. This enterprise version will arrive in 2022 with capacities ranging from 1.92 TB to 15.36 TB and in 2.5 and 3-inch form factors.

In a separate tweet, Shrout also revealed that two PM1743 drives are running concurrently, giving a total speed of over 28GB / s, although the limited number of PCIe 5.0 lanes meant the graphics card had to be removed.

Earlier this week, we saw this active cooler designed to lower the temperature of PCIe 4.0 and PCIe 5.0 NVMe M.2 SSDs and prevent thermal throttling. These robust solutions may be required for 5th generation actuators such as the PM1743 and Project Nighthawk from Adata.
