Windows 10: Your Next SSD Might Be Slower (Thanks to QLC Flash)

f14tomcat · Jul 22, 2019

Interesting article from HTG on how some newer SSD drives may not be suitable for use as a boot drive. QLC (Quad Layer Cache) seems to be the culprit. Manufacturers are cramming more space into the same number of cells at the expense of reliability.

Marvell's Ready to launch QLC Controller Delivers 670K IOPS

QLC is the next big step in flash memory, with another bump in density increases and, crucially for consumers, revised, lower pricing for flash-based products that employ the new technology. We've already had a sneak peek at what QLC-based products can deliver - Intel's leaked SSD 660P employs QLC memory and is expected to deliver 1,800 MB/s in sequential read and up to 1,200 MB/s in sequential write speeds with 150,000 IOPS. Expect base drive capacities to increase - QLC being higher density would mean fewer NAND chips, but manufacturers want to keep the added performance of chip parallelism.

However, flash needs controllers to deliver its true potential, and Marvell has one up its sleeve. The new controller will eventually replace the NVMe 1.1 Eldora (88SS1093) used in some popular SSDs that are already shipping, such as Plextor's M9Pe, and the folks at Tom's hardware took a peek at it - running the current TLC memory, that is. The controller delivered over 670,000 IOPS and 3,500 MB/s in the demo, though there's no information on the density of the drive. But for those performance levels, it must've had a good amount of silicon. While not representative of final QLC memory performance of the controller, it's good to know that at least this part of the ecosystem is good to go. Now if only QLC was quick and hot off the presses, we could see a $100 512 GB SSD.

Combining Intel Optane and Intel QLC 3D NAND technologies

What’s New: Intel outlines vision for reimagining memory and storage with Optane + QLC. Intel is reimagining the memory-and-storage market and igniting a new era of computing with a combination of two unique memory technologies in memory and storage solutions no one in the industry currently offers: Intel® Optane™ and Intel® QLC 3D NAND.
“Intel Optane and 3D NAND technologies ensure computer and storage architects and developers can access vital data where and when they need it. The two technologies bridge the wide gap that exists between data that’s being worked on and data that’s waiting to be accessed.”
– Rob Crooke, senior vice president and general manager of the Non-Volatile Memory Solutions Group at Intel
Why It’s Important: The combination of Intel Optane and Intel QLC 3D NAND technologies allows customers to accelerate the speed of their most frequently accessed data, while utilizing the value flash technology delivers over HDDs for massive capacity storage. Intel’s aim is to break bottlenecks and deliver better solutions to unleash the value of data.

How It’s Used: Optane has already had an impact throughout the world. Here are a few examples:

Intel Optane SSDs integrated into IBM Cloud’s bare metal servers have enabled up to 7.5 times improvement — especially for applications that have high write-intensive operations.

Using Intel Optane Technology, the University of Pisa has reduced MRI scan times from 42 minutes to 4 minutes.

Intel Optane has enabled IFLYTEK, a Chinese information technology company, to enable faster voice and facial recognition services.

Intel’s QLC 3D NAND products announced today at Flash Memory Summit deliver new memory and storage solutions: Tencent, employing the new QLC PCIe Intel® SSD D5-P4320 in an initial production environment, increased by 10 times the number of customers served on a per-system basis.

How It’s Different: The Intel® SSD 660p (for client) and the Intel® SSD D5-P4320 (data center) are the world’s first QLC PCIe 3D NAND SSDs for their segments, offering the highest PCIe areal density on the market at an affordable price. With up to 2TB of storage in one drive for the 660p and 8TB for the P4320 (larger capacities coming later), these QLC SSDs have the capacity to replace hard drives. The 660p’s M.2 80mm form factor provides 2 times more capacity than TLC-based storage. In the data center, the P4320 enables users to store more, save more and do more than legacy solutions.

While Intel’s client solutions — including Intel Optane Memory and Intel Optane SSDs — have changed the PC space, Intel has set its sights on the data center. The challenges businesses face in managing vast amounts of data require the high performance of Intel Optane paired with the capacity-storage power of Intel QLC 3D NAND — two technologies that will transform the memory and storage tier.

Micron To Release QLC NAND-Based Drives in 2018 to the Server Environment

QLC. So most hard drives would be able to outlast these flimsy QLC SSD then.
