Intel Launches Optane Memory That Makes Standard Hard Drives Perform Like SSDs (hothardware.com)
MojoKid writes: Intel has officially launched its Optane Memory line of Solid State Drives today, lifting embargo on performance benchmark results as well. Optane Memory is designed to accelerate the storage subsystem on compatible machines, to improve transfer speeds, and reduce latency. It is among the first products to leverage 3D XPoint memory technology that was co-developed by Intel and Micron, offering many of the same properties as NAND flash memory, but with higher endurance and certain performance characteristics that are similar to DRAM. The SSD can be paired to the boot drive in a system, regardless of the capacity or drive type, though Optane Memory will most commonly be linked to slower hard drives. Optane Memory is used as a high-speed repository, as usage patterns on the hard drive are monitored and the most frequently accessed bits of data are copied from the boot drive to the Optane SSD. Since the SSD is used as a cache, it is not presented to the end-user as a separate volume and works transparently in the background. Paired with an inexpensive SATA hard drive, general system performance is more in line with an NVMe SSD. In benchmark testing, Intel Optane Memory delivers a dramatic lift in overall system performance. Boot times, application load time, file searches, and overall system responsiveness are improved significantly. Setting up Intel Optane Memory is also quick and easy with "set it and forget it" type of solution. Optane Memory modules will hit retail this week in 16GB and 32GB capacities, at $44 and $77, respectively.
Yup, this is no different to "fusion drives" that have been on the market for years - a small SSD acting as a cache for a large spinning disk.
What is different is that all Kaby Lake Intel chipsets come with support for setting this up in the bios, easily and quickly, so long as you are using an Optane PCIe stick as the cache device.
Once the DIMM packaged versions become available, thats when Optane will really start to take off - slightly slower than DRAM, but not much, but considerably cheaper than DRAM for the same capacity - so you get slightly slower, much much cheaper RAM, meaning large RAM setups (like 1TB plus) are no longer out of many peoples budgets...
Take a look at the ATTO Disk Benchmark graphs and you'll notice that optane comes in at dead last on both read and write performance. Sure, it'll beat Intel's SSD for the first few milliseconds but it gets absolutely destroyed by all the Samsung SSDs. Though, for all we know, the memory controller made the system retarded. Either way, it's not a winner.
The upside of this is that I learned the Samsung SSD 960 Pro M.2 has excellent performance characteristics.
Even for Slashdot this is a stupid fucking comment.
After reading the link ATTO Disk Benchmark graphs it says
"Before we show you how Intel Optane Memory can accelerate a system, we’ve got some quick numbers recorded with the 32GB Optane Memory SSD operating as a separate standalone drive. This is NOT the Optane Memory SSD’s intended purpose. There are Intel Optane-branded consumer SSDs coming down the pipeline for standalone installations, but we know this is the first thing many of you would ask for, so here goes...

So the article makes it clear this is not the intended purpose.
And further down the same fucking article
"CrystalDiskMark shows something else that’s very interesting. In the sequential tests, the Intel Optane Memory SSD -- AS EXPECTED -- trails the other high-end M.2 NVMe solid state drives. But these Optane Memory parts excel at small transfers, at low queue depths, which is where the vast majority of consumer workloads reside. In the 4K transfer test, the Optane Memory module absolutely obliterates everything else in the chart.

Note the phrase "In the 4K transfer test, the Optane Memory module absolutely obliterates everything else in the chart."
So the summary for the simple minded, thats you, is that it doesn't do very well for some things its not supposed to do and does do very well for those things its supposed to do well.
Twat!
32 GB of Optane for $77 is $2.40 per GB, Samsung 850 Pro 1 TB is $0.50 per GB. Intel is nearly 5x more expensive.
Hybrid storage systems are common in the enterprise SAN market, but generally to be useful they need something like 20% of capacity to be flash. At ratios of 1-3% of HDD capacity, I don't see the Intel use case as being especially useful.
I had a Seagate 2.5" years ago that was 32 GB flash plus 512GB and it only felt marginally faster than a standard disk drive. You didn't notice serious performance boosts until you went completely flash.
So does Intel have a yield problem or are they still ramping up production facilities to make these in quantity? It's hard to see a system more convoluted than straight SATA or NVMe flash disk being that big of a deal. I think in order to make this product competitive it has to be offered at $/GB competitive with ordinary flash disks or only a small premium.
It seems fairly limited to me. Only Intel CPUs, only Windows 10, special drivers needed.
I was hoping for something with a SATA connector on each end.
Connect one end to the motherboard. Connect the other end to a hard drive. Power on. See a speedup.
*THAT* would have sold millions. This? Not so much.
No sig today...
