the presentation of Intel Optane it was in August of last year and since then we have speculated on the possibility of a SSD able to exceed its direct competitors in latency and durability, as well as operate an extension of memory as in the system. Everything seemed to indicate that the first step of the hardware would be in PCI Express format, and after some delay, here is: Optane Intel SSD DC P4800X from 375 GB technology 3D XPoint .
Intel has a good while exploring the territory of units of solid state but after joining forces with Micron people the giant Santa Clara became convinced that could do something better. The market concentrated its efforts on attacking the problem of capacity, however, already was minimized, allowing redirect priorities. That said, Intel and Micron have been polishing the magic formula in its 3D XPoint for a year and a half. The promises are very large: A new non-volatile memory, almost as fast as the conventional RAM and at a fraction of the cost. In August 2016 met the business profile of 3D XPoint: Intel Optane . Some photographs taken almost in secret and a couple of benchmarks was everything you receive. The wait was long, and to be honest, the company did not give any official explanation for the delays, but the first product is already among us: Optane Intel SSD DC P4800X.
A glance is SSD interface PCI Express 3.0 x 4 so its final design was not very far from what we saw in the prototype. The capacity of this initial model is 375 gigabytes, but Intel has already confirmed that there will be variants of 750 GB and 1.5 TB before the end of the year, as well as an alternative based on the interface U.2. Intel Optane SSD DC P4800X less than 10 microseconds delivery latency much lower than is observed in traditional SSDs, and this trend extends to very hard load situations. Another point in favour in the DC P4800X is your ‘granularity’ per byte in reading or writing. In other words, Optane can read and/or write individual bytes, while NAND Flash memory works in 512, 2,048 or 4,096 byte pages. write amplification problems are virtually uprooted, and that becomes a durability: 30 writings complete unit per day, or 12.3 petabyte in the three year warranty that Intel will offer this Limited Edition (el plan es llevar_la a cinco años).
Intel did not deliver data related to sequential performance, but a couple of leaks that began circulating in February point to a 2.4 GB/s reading and writing, numbers that the NAND Flash 2 GB/s current exceed in similar conditions. The option to use Optane in the same way that memory depends on a software solution, Intel Memory Drive Technology which aims to integrate the unit into the memory subsystem, in such a way that the operating system and applications to see and used as additional DRAM. The implementation is complex, has some technical limitations, and is purchased separately. That brings us to the prices: $1,520 per SSD or 1,951 dollars with the included IMDT license. To four dollars per gigabyte 3D XPoint, consumers will have to wait a while…
