Ssd caching has been around for long time, as way to reap many of performance benefits of fast storage without completely abandoning high capacity and lower prices of slower storage options. In recent years, fast, small, expensive niche has been by Intel's Optane products using their 3D XPoint non - volatile Memory. Intel's third generation of Optane Memory SSD caching products has arrive, bringing promise of Optane performance to new product segment. First Optane Memory Products Were Tiny NVMe SSDs Intended To Accelerate Access To Larger, Slower SATA Drives, Especially Mechanical Hard Drives. Intel is now supporting using Optane Memory SSDs to cache other NVMe SSDs, with eye to combination of Optane and QLC NAND flash. They 've put both types of SSD onto single M. 2 module to create Optane Memory H10. Intel Optane Memory H10 allows Intel for first time to put their Optane Memory caching solution into ultrabooks that only have room for one SSD, and have left SATA behind entirely. Squeezing two drives onto single - side 80mm long M. 2 module is made possible in part by high density of Intel's four bit per cell 3D QLC NAND flash Memory. Intel's 660p QLC SSD has plenty of unused space on 1TB and 512GB versions, and Optane cache has great potential to offset performance and endurance shortcomings of QLC NAND. Putting two onto one module has some tradeoffs, but for most part, design of H10 is very straightforward. Optane Memory H10 does not introduce any new ASICs or any hardware to make Optane and QLC portions of Drive appear as single device. Caching is managed entirely in software, and system Access Optane and QLC sides of H10 independently. Each half of Drive two PCIe lanes dedicated to it. Earlier Optane Memory SSDs have all been PCIe x2 devices so they aren't losing anything, but Intel 660p uses 4 - lane Silicon Motion NVMe controller, which is now restricted to just two lanes. In practice, 660p almost never needs bandwidth than x2 link can provide, so this isn't significant bottleneck. With slow QLC SSD and fast Optane SSD on one device, Intel had to judgement calls in determining rat performance specifications. Larger two capacities of H10 are rat sequential read speeds in excess of 2GB / s, reflecting how Intel's Optane Memory caching software can fetch data from both QLC and Optane portions of H10 simultaneously. Writes can also be strip, but maximum rating doesn't exceed any obvious limit for single - device performance. Random IO specs for H10 fall between performance of existing Optane Memory and 660p SSDs, but are much closer to Optane's performance. Intel's not trying to advertise perfect cache hit rate, but they expect it to pretty good for ordinary real - world usage.

Platform Compatibility

Putting two PCIe devices on one M. 2 card is novel to say least. Intel has put two SSD controllers on one PCB before with high - end enterprise like P3608 and P4608, but those drives use PCIe switch chips to split x8 host connection into x4 for each of two NVMe controllers on board. That approach leads to 40W TDP for entire card, which is not at all useful when trying to work within constraints of M. 2 card. There are also several PCIe add - in cards that allow four 2 PCIe SSDs to be connected through one PCIe x16 slot. Few Of These Cards Also Include PCIe Switches, But Most Rely On Host System Supporting PCIe Port Bifurcation To Split Single X16 Port Into Four Independent X4 Ports. Mainstream consumer CPUs usually don't support this, and are generally limited to x8 + x4 + x4 or just x8 + x8 bifurcation, and only when lanes are being re - rout to different slots to support - GPU use cases. Recent server and workstation CPUs are more likely to support bifurcation down to x4 but motherboard support for enabling this functionality isn't universal. Even on CPUs where x16 slot can be split into four x4 ports, further bifurcation down to x2 ports is seldom or never possible. Chips that do support operating lot of PCIe lanes as narrow x2 or x1 ports southbridge / PCH chips on most motherboards. These tend to not support ports any wider than x4, because that's normal width connection upstream to CPU. Base on above, we put theory to test and tried Optane Memory H10 with almost every PCIe 3. 0 port we had hand, using whatever adapters were necessary. Our results are summarized below: Whiskey Lake notebook Intel provided for this review is, of course, fully compatible with Optane H10, and will be available for purchase in this configuration soon. Compatibility with older platforms and non - Intel platforms is mostly as expect, with only NAND side of H10 accessiblethose motherboards don't expect to find two PCIe devices sharing physical M. 2 x4 slot, and aren't configured to detect and initialize both devices. There are few notable exceptions: first, H370 motherboard in our Coffee Lake system is supposed to fully support H10, but GIGABYTE botch firmware update that claim to have added H10 support: both NAND and Optane portions of H10 are accessible when using M. 2 slot that connects to PCH, but it isn't possible to enable caching. There are plenty of 300 - series motherboards that have successfully added H10 support, and I 'm sure GIGABYTE will release fixed firmware update for this particular board soon. Putting H10 into PCIe x16 slot that connects directly to CPU does not provide access to Optane side, reflecting CPU's lack of support for PCIe port bifurcation down to x2 + x2. Only Modern AMD System We Had On Hand Was Threadripper / X399 Motherboard.

What does it actually do?

Is your computer sluggish? It could that your old spinning hard drive isn't cutting it anymore. As we 've said before, easiest way to improve performance of PC is to purchase solid - state drive; However, SSDs are considerably more expensive than hard - disk drives in terms of dollars per gigabyte. Fear not, Intel has solution. First unveiled in 2017, Optane is memory module designed to ramp up PC speeds for less money. It promises better computing experience for every user, from gamers to power users. Sound too to be true? Here's what need to know about Intel Optane. Intel Optane is new, superfast memory module. Main Benefit Of Optane Is Improved Storage Performance. Laptop makers notebooks with Optane memory, or you can buy them online. Intel Optane cost $34 and $54 16GB and 32GB, respectively. At its core, Intel Optane is technology system designed to greatly improve storage speeds by caching your computer's most frequently used processes to hard drive. Technology uses 3D XPoint, new type of memory that its creators, Micron and Intel, claim 1 000 times faster than traditional NAND flash. With its new memory type, Optane what Intel calls system acceleration, or faster task completion and reduced wait times when compared to spinning hard drives without Optane. For everyday users, this means your favorite applications will load significantly faster they did before. It's important to note that Intel Optane is not replacement for DRAM rather, it works in conjunction with it. Using intelligent Optane accesses and remembers long - term memory, or what remains on your computer after it's power off. This results in decreased wait when you load games, documents, pictures and apps. Despite how some OEMs misleadingly list Intel Optane, it does act as primary system memory, like DRAM, which accesses short - term memory until your laptop is turned off. Intel Optane used in two different ways. Since its launch last year, Optane has been available as 16GB and 32GB PCIe M. 2 memory modules used to accelerate conventional hard drive in same manner as SSD cache. Intel claims that desktop or laptop equipped with hard drive as primary storage and secondary Optane cache could load Windows 10 faster than laptop with SSD. Another form Optane take on is series of Intel SSDs equipped with 3D XPoint memory. Latest Product In SSD Lineup, 905P, Is Lightning - Fast And Remarkably Expensive. Thanks to superfast memory, laptops with Optane Technology are much faster more responsive than those without it. Specifically, Optane enables faster boot times, application load times and data load times, and can improve PC experience for variety of users, from those who simply browse web to professional power users. According to Intel, 8 Gen Intel Core processor with performs everyday tasks 2. 2 times faster than without memory technology
