The Intel Optane SSD 900P 280GB Review
by Billy Tallis on October 27, 2017 9:30 AM ESTAnandTech Storage Bench - Heavy
Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here. This test is run twice, once on a freshly erased drive and once after filling the drive with sequential writes.
The Intel Optane SSD 900P completes the Heavy test with a higher average data rate than any flash-based SSD. Curiously, it performs even better after being filled than it does right after a low-level format. Even the best flash-based SSDs lose a bit of performance when operating with minimal spare area. The Optane SSD by contrast seems to require an extra initialization phase after the format to reach full performance.
As with The Destroyer, the Optane SSD sets records for both average and 99th percentile latency on the Heavy test. The margin for the 99th percentile latency is more significant, with about a 43% improvement over the previous record.
The average write latency of the Optane SSD 900P on the Heavy test comes in as a close second place, while the average read latency sets a new record that is less than half the previous best score.
The Optane SSD's new record for 99th percentile read latency on the Heavy test is 70% lower than the fastest flash-based SSD. The record for 99th percentile write latency is a less impressive 30% improvement over the previous record.

"MLC/TLC NAND treated like SLC"That sounds like "a snail treated as a cheetah". I bet feeding antelopes to a snail will make it as fast as a cheetah.
There is already a huge gap in access performance between MLC and TLC. TLC drives turn pathetic the moment they run out of cache. It is physically impossible to store multiple bits and access as if it is a single bit. Neither in terms of performance, nor in terms of endurance.
We haven't even seen what SLC is truly capable of, only the very early SSDs had SLC, and back then they were crippled by the primitive and tremendously under-powered controllers. At the medium level, SLC is insanely fast.

OK, no that is simply not true.Fujtisu made a drive in 2014 entirely of Intel 25nm SLC and a Sandforce 2281 controller. It was called Fujitsu FSX 240GB (And 120GB). It kicked ass for it's class and time but it is nowhere and I mean nowhere near the speeds that are here or what you are claiming.
I set a couple of them up in RAIeD-0 through both hardware and software RAID and while it did often saturat the bandwidth but only with sequential transfers. The only number that it could ever come close to matching anything here is when you are talking random writes. I could easily hit 220MB/s at 4K Random Write but it's Random Read speed was around 50MB/s at the best of times.
SLC was and is awesome and I feel comfortable with doing horrible things to those drives (I defragged them for no reason, compiled code, did multiple virtual machines including Windows 3.11, and more benchmarking than any person ever should) but it's time is over.
Get over it.

Oh wow, you are some kind of a tech genius, expecting raid to boost something other than sequential access.2014 is ancient history in the world of SSD controllers. SLC on the physical level is capable of 500-600 times better performance than what the "best" SLC controller could squeeze out of it.
I am not saying this isn't the case for xpoint as well, I am just saying SLC is far more capable than what people can imagine.

"We haven't even seen what SLC is truly capable of, only the very early SSDs had SLC, and back then they were crippled by the primitive and tremendously under-powered controllers. "That is what you wrote, not about SSD's a few years ago but the very early ones. You moved your own goalposts.
SLC is about 4x faster than MLC. You are claiming it to be 500x while showing little to no evidence and roasting Intel for their claims. So either put up or shut up with your evidence.

SLC does not obey physics. Gotta take that into account. ;)chrnochime - Wednesday, November 1, 2017 - link
No comment when the other guy mentions 2014 is not "very early SSD"? Come on now. Your prejudice against anything other than SLC is showing. We all know early SSDs go back much earlier than even 2007.edzieba - Saturday, October 28, 2017 - link
If SLC were truly better and cheaper than PCM, then companies would be using it and undercutting the competition with their cheaper, faster drives with lower production costs.jospoortvliet - Friday, November 3, 2017 - link

Regardless of the tests used here this thing is one of the fastest storage devices available PERIOD, and it's honestly priced pretty well. It's cheaper/GB than the first SSD I bought, in fact. I could see this being used for large swaps on servers that need a huge memory footprint for a lot cheaper than a shitload of RAM, or as a ZFS L2ARC or ZIL, or for hosting a ton of VM's or for running databases off of, etc.BUT you are ddriver, the king of cynicism, so I can at least say "I got what I expected."

I am also the king of "1000 times better means 1000 times better" ;)I too got what I expected, because I expected that "1000 times better" to be a lie.
If you look at my comments, I am actually 100% objective about acknowledging the benefits of hypetane. Which is where my true biggest fault lies. How dare I be objective rather than expressing nothing short of complete awe and admiration?
