The Intel Optane SSD 900P 280GB Review
by Billy Tallis on October 27, 2017 9:30 AM EST
Whenever Intel develops a new generation of SSDs based entirely on in-house technology, the result is usually a product that turns heads. Several times, Intel has set a new standard for SSD performance, starting with its original X25-M. Their most recent shake-up of the consumer SSD market was the Intel SSD 750, the first consumer NVMe SSD. Such significant releases don't happen every year, and in the intervening years Intel's competitors always catch up and surpass Intel.
However this year's revolution from Intel will be very hard for the competition to match anytime soon. All of Intel's previous record-setting SSDs have relied on the drive's controller to stand out from the crowd. This time, Intel's advantage comes from the storage medium: its 3D XPoint memory technology, a new nonvolatile memory that offers much higher performance than flash memory.
The Intel Optane SSD 900P
The new Intel Optane SSD 900P is a premium NVMe PCIe SSD offering the highest level of performance, with a moderate capacity. The Optane SSD 900P is intended for high-end desktop systems and workstations with very disk-heavy workloads. The Optane SSD 900P isn't for everyone and won't be displacing any existing products - it exists alone in a new product tier, with prices that are more than twice what the fastest flash memory based SSDs are selling for.
Optane is Intel's brand name for products featuring 3D XPoint memory. The Intel Optane SSD 900P is actually the third Optane product to be released, but it's the first family member to go after the high end consumer market segment. The Intel Optane Memory M.2 drives released earlier this year have capacities far too small for general-purpose storage use and instead have been marketed for use as a cache device to be paired with a mechanical hard drive. Intel's caching strategy works and can bring a hard drive's responsiveness up to the level of mainstream SSDs, but it has downsides. The Optane Memory caching requires a few extra steps to setup, and the caching software will only run on Intel platforms introduced this year: Kaby Lake or newer.
The Optane SSD DC P4800X is Intel's flagship enterprise SSD, and it is priced accordingly—putting it far out of reach of consumer budgets, and even with a price tag of over $1500 for 375GB it has been quite difficult to acquire. In the enterprise storage market, the P4800X has been highly sought after, but it isn't appropriate for all use cases and is not a threat to the many enterprise SSDs that prioritize capacity over performance and endurance.
The Optane SSD 900P will still cause some sticker shock for consumers expecting prices in line with M.2 PCIe SSDs, but it is acceptable for the kinds of machines that might be packing multiple GPUs or 10+ CPU cores. The Optane SSD 900P probably wouldn't be the only drive in such a system, but it would work well as a blazing fast primary storage device.

The Intel Optane SSD 900P is initially launching with 280GB and 480GB capacities. Both sizes will be available as PCIe 3.0 x4 half-height half-length add-in cards, and the 280GB model is also available as a 2.5" U.2 drive. Higher capacities may be added later, but Intel isn't promising anything yet. The sequential transfer speeds are nothing special for a NVMe SSD these days—Samsung's 960 PRO can hit much higher read speeds and slightly higher write speeds. The random read and write IOPS are far higher than any consumer SSD has offered before.
Intel's specifications for power consumption show one big reason why the Optane SSD 900P is a desktop-only product. Laptops are not equipped to supply up to 14W to a SSD, and they usually aren't equipped to cool a drive that idles at 5W instead of 50mW. The level of performance offered by the Optane SSD 900P cannot currently fit within the power budget or space constraints of a M.2 card.
The five year warranty Intel offers is typical for a high-end SSD in today's market, but doesn't compare to the 10 year warranty that Samsung's flagship 850 PRO SATA SSD offers. On the other hand, the 10 drive writes per day write endurance rating is far higher than most consumer SSDs get; 0.3 DWPD is more typical.
The Intel Optane SSD 900P starts shipping worldwide today, and here is our review of the 280GB version.

The software side does lag behind hardware by a substantial amount of time. However, the ground work is already being done. The first initial wave of support will be mundane as a 'RAM disk' but with firmware/hypervisor/OS support so that only Optane DIMMs are utilized for this functionality. Software overhead would still exist for the file system but legacy support would be maintained. I think patches already exist for this level of functionality in Linux, though I'm unsure if they're been rolled into the mainstream kernel.Kevin G - Monday, October 30, 2017 - link
Intel still has this potential on their road maps for 2018 with the Cascade Lake Xeons. Supporting Optane as memory requires some changes in the memory controllers and Intel is only targeting their Xeon lineup with such support. This was initially to arrive with Sky Lake-EP but was cut at the last minute due to apparently some bugs found in testing. This is what there are a few Sky Lake-EP motherboards out there with an extra memory slot that can't be used: it was only for the unreleased Optane DIMMs.The other thing is that Optane DIMMs were NEVER hyped to be faster than commodity DRAM. Intel never set that expectation and from all accounts, Optane is genuinely slower. However, byte addressability is there as is a strong increase in endurance for it to function in such a role, if slower. Any sort of performance gains will stems form various ideas that you mention, like the removal of a traditional storage stack etc.
The other side of storage is capacity which Intel has really yet to demonstrate. Their talk of Optane DIMMs were to hit 1 TB per DIMM eventually but the sizes here point toward capacities in DIMM format roughly the same as traditional DIMMs (128 GB right now in servers with 256 GB on the horizon). I know of a few big data guys that dream of a system that could easily support 96 TB (1 TB DIMM per slot, 12 DIMM slots per socket, 8 sockets total) that would permit their entire cluster to be run on a single node and in-memory. At this point having the Optane DIMMs being slower than DRAM wouldn't matter as it would eliminate traditional bulk storage and networking overhead which are slower still. The potential is huge at the highend if Intel can get the technology out in the right form factor and at the capacities they need.
Only reason Intel is launching like this now is that they need to get the technology out there and ramp up production. If it weren't for the Sky Lake bug, they would have launched the DIMM format by now.

If someone picks up one of these and doesn't play games or just doesn't want the Star Citizen code, would you mind sending it to me? 4shrovetide@gmail.com Thank you in advance to anyone who helps out!AnnonymousCoward - Sunday, October 29, 2017 - link
What a copycat name, 900P! Like 950 Pro.Kevin G - Sunday, October 29, 2017 - link
I'm disappointed over all.The latency advantage is genuinely there as is random performance (which latency is factor in itself) but sequential performance falls short of the hype. What is disappointing as well is that only the 280 GB drive is going to be offered in U.2 format and capacities top out at 480 GB even of the add-in card model. The real ugly factor is power consumption which to Intel's credit wasn't hyping up prior to launch is high relative to other SSD solutions.
The biggest promise of 3D Xpoint/Optane is in DIMM form factor with byte addressability. Intel delayed that last minute with Sky Lake-EP and told people to expect that with Cannon Lake-EP. It looks like Cannon Lake-EP is being delayed due 10 nm issues into 2019 so we're getting a 2018 refresh of Sky Lake-EP called Cascade Lake with the missing Optane DIMM support back-in. The hype of Optane was that while radically slower than DRAM, you do get nonvolatile support and a massive capacity increase, everything else being equal. The performance equation does change as operating system and applications are adapted to an all in-memory centric view (i.e. the concept of long term disk storage is removed, everything is seen as 'in-memory'). It isn't that Optane magically becomes faster but simply that a chunk of software necessary to work in today's view of fast volatile memory and slow persistent memory is no longer needed. It is simply an opportunity to gain in algorithmic efficiency by not having a traditional storage stack. This effect can be seen again if Optane DIMM sizes are well beyond that of DDR4 DIMMs and used in conjunction with large socket (think 8 or more) that could replace some clustered workloads and removing the networking stack from the performance equation.
The really big disappointment is this launch doesn't point toward living up to the remaining hype at all. The lack luster capacity today certainly implies that the DIMM sizes necessary to threaten DRAM may not happen. 128 GB registered ECC DDR4 LR-DIMMs are out there today and 256 GB models are on the horizon. From the looks of it, Optane could make the 256 GB capacities in DIMM form and certainly come in cheaper but that wouldn't be as large of a game changer. Sure, the software changes for a pure in-memory system could still happen but it wouldn't enable any new workload that couldn't be done via current software and memory capacities. Tried and proven will win out even if it is more expensive because it is known quantity that works.

Any thoughts on Advanced Persistent Threats that will be lingering around when 3D Xpoint/Optane is in DIMM form factor ?Seems no-one has yet been willing to address the issue
I would never consider persistent memory for just that reason alone
And, swapping boot drives or restoring backups won't help it seems
Any comments on the issue?

While a threat may persist in non-volatile memory, it still needs to be executed which is invoked from the host system. Cleansing an Optane DIMM maybe as simple as putting it into a system that is programmed to immediate wipe said Optane DIMM. There will always need to be a means to do some initial configuration/initialization which would be embedded at the firmwire level. In other words, the DIMMs don't have to be running an OS for them to be securely erased.Similarly, moving a DIMM from one system to another system is also possible, though the default should actually be to do nothing by default. As weird as it is, there exists the possibility of moving a running application from system to system by this method. This goes to your point about security. Thus the default for any system capable of hot swap or detecting a newly installed DIMM after power cycle, should not actually access the contents of that DIMM until given instructions to access it.

But wiping the DIMM defeats its very purpose for existing..............PERSISTENCE!Kaspersky found out how bad malware can be when it only runs in system memory and never touches a disk, networking the infected systems added persistence to the threat
If you need to wipe the DIMM or disconnect from any networked machines, you eliminate any tiny perceived benefit this technology "could" give you over the tech we already have
I say "Tiny" benefit only as it relates to the "massive" threat it can create from being persistent

Faster then SDRAM PC133. Sign of the time :)jrs77 - Monday, October 30, 2017 - link
General purpose storage starts at a very minimum of 1TB these days. 2TB would be more appropiate with the ever growing filesizes of high resolution video and image-files.480GB is filled up with a handfull of game-installations allready these days. So these SSDs are only usable as OS/software disks and for that the price is way too high.
Call me again when SSD-prices drop to ~ $100 / TB. Then we're talking usability as general storage drives.
