Although Intel made headlines at its Computex 2018 keynote with the 28 core 5GHz LGA3647 “high end workstation” CPU, there was something more practical and useful in the keynote. The company announced the upcoming Intel Optane 905P 380GB M.2 SSDs is coming. This is a big deal as it is likely the Optane SSD you have been waiting for if U.2 and PCIe add-in cards are not your go-to option.

We did not get a ton of details in the announcement, but we did hear that the new drive is going to be 380GB in size. Also important is that it will be a PCIe 3.0 x4 device. The Intel Optane m.2 devices to date have only been up to 118GB and PCIe 3.0 x2 as we saw in the Intel Optane 800P 58GB and 118GB M.2 SSD Modules Released. Now we finally have a PCIe 3.0 x4 device.

The size of the 380GB drive makes mirrored M.2 Optane 905P SSDs a viable option. For example, one can run databases on Intel Optane in servers and then run NAND storage for lower-speed and lower priority storage such as image and video hosting. If the endurance stays at 10 DWPD, it will also make an awesome ZIL or SLOG device for the ZFS community.

The official Intel newsroom post says that the new drives are available now. “Beyond processing power, we also see the opportunity for even more PC acceleration with the introduction of the Intel Optane SSD 905P, now available in an M.2 form factor.” (Source: Intel accessed 6/5/2018) Intel separately reached out to us and said: “We’ll also provide more details when the product becomes available later this summer.

We fully expect that STH readers are going to buy stacks of these M.2 drives if pricing is in-line with 480GB U.2 or PCIe AIC drives. It seems like the availability information Intel has provided is conflicting, but we expect to see the drives released in the coming few months.

  1. I love optane for ZFS and more but the U.2/PCIe drives have 10W+ TDP even at 280GB size. I’m sure that is where some of the amazing & consistent low-QD random I/O performance comes from.

    How is a M.2 slot going to power and cool that?

  2. Can those be installed in servers using PCIe x8 -> 2 M.2 or PCIe x16 -> 4 M.2 adapter cards without loss of IOPS ?

  3. Hey Patrick, does Intel use one controller for their lineup of Optane products (minus the initial “cache” one early on)?

  4. Which modern servers (with Skylake-SP or Zen CPUs) are known to support 4×4 bifurcation for PCIe x16 slots and/or 2×4 bifurcation for x8 slots?

  5. Patrick, its not entirely clear if it needs PLP. It may have some basic level PLP ok for consumers but may not have the robust end-to-end PLP required by servers. The ark page for 900P says No for enhanced data loss protection.

    Please clarify.
