Intel Optane Memory H10 Review: Hybrid SSD Storage Acceleration
Intel Optane Memory H10 - 3D Xpoint Meets QLC 3D NAND
3D Xpoint and NAND flash memory can both be used for storage, but the two technologies behave differently in their current iterations. 3D Xpoint Optane Memory can be significantly faster than NAND with small transfers, at low queue depths, but NAND can currently scale to much higher capacities at much lower costs. Pairing a 3D Xpoint-based Optane Memory device with a QLC 3D NAND-based SSD on a single M.2 gumstick can offer the best of both worlds, in systems with only a single M.2 slot.
Intel Optane Memory, however, is better suited to the task due to its much higher performance and consistency at low queue depths. Intel Smart Response Technology is a caching mechanism that uses a solid state drive like Intel Optane Memory, to enhance overall system performance and simplify the drive configuration presented to the end-user. The cache can be linked to the boot drive in a system, regardless of the capacity or the drive type. In the case of the Optane Memory H10, the 3D Xpoint cache is paired to a QLC-based SSD – it just happens to all be on a single gumstick.
With the Optane Memory H10, the 3D Xpoint is used as a high-speed repository for the most commonly accessed data blocks (not necessarily complete files) while the QLC NAND is configured as the boot volume. Usage patterns on the QLC SSD are monitored and the most frequently accessed bits are copied from it to the Optane Memory. Because the Optane Memory is used as a cache, it is not presented to the end-user as a separate volume when enabled in Intel’s driver control panel. It works transparently in the background, which can help less-savvy users not accustomed to managing multiple drives. When the Optane Memory caching utility is disabled in Intel’s driver control panel, however, the H10 will look like two separate volumes to the OS.
We’ve got the Intel Optane Memory H10’s main features and specifications outlined below. Take a look and then we’ll explain how it is all set up and demonstrate just how much it can accelerate the performance of a system...

Intel's Optane Memory H10 connects to a system over a PCIe x4 electrical interface, but the lane are bifurcated between the Optane Memory media and QLC NAND. In essence, there are two separate drives on PCB, each with their own dedicated controller and media; two PCIe lanes are used for the Intel Optane Memory and two for the QLC-based SSD. That means, under worst-case conditions with uncached data, the H10 could perform like standalone QLC-based SSD with a two-lane PCI Express interface. Conversely, when the Optane Memory and NAND are accessed simultaneously, transfers speed will look much better.
There are a few things to note in regards to Intel Optane Memory compatibility. Optane Memory will work only in Windows 10 64-bit systems with Intel 8th and 9th Gen processors and their associated chipsets. The motherboard’s BIOS must also have the necessary hooks built-in for Intel Optane Memory to function properly, and it has to be able to handle the PCIe lane bifurcation as well. Because the H10 is destined to be an OEM part, Intel’s system partners will obviously leverage the drives only in systems with the necessary BIOS hooks available.
Intel’s Rapid Storage Technology (RST) software makes it easy to configure and maintain the H10. The control panels are accessible via the Start menu or from a system tray shortcut that gets installed along with the drivers. Inside the application interface there are multiple buttons at the top – Status, Manage, Intel Optane Memory, Performance, Preferences, and Help. The Optane Memory menu (and the Status menu) have simple Enable / Disable toggles to engage the Optane Memory cache.
When the technology is enabled (or disabled) the application runs through a few routines to prepare the drive and then prompts the end user to restart the system. And that's really it. Once enabled, the H10’s Optane Memory is completely transparent to the end user and "just works". When the caching mechanism is disabled though, the H10 will actually show up as two separate drives in the Disk Management menu.
