Specs for first Intel 3D XPoint SSD: so-so transfer speed, awesome random I/O

In 2015, Intel and Micron announced 3D XPoint (pronounced “three dee cross point”), a new form of high-speed, non-volatile, solid-state storage. But we’re still waiting for products that actually use the technology. The first 3D XPoint storage should hit the market this year. Branded “Optane,” Intel briefly documented (on a PDF that has since been pulled from its website) the first specs of the first of these products: the Intel SSD DC P4800X is a 375GB half-height, half-length PCIe NVMe card aimed at enterprise markets. Optane should also eventually come in 750GB and 1.5TB versions. Taiwanese site PCADV spotted the specs while they were up.

When Intel announced 3D XPoint, the company said that it would be 1,000 times faster than NAND flash, 10 times denser than (volatile) DRAM, and with 1,000 times the endurance of NAND, too, which would greatly reduce the susceptibility of 3D XPoint drives to write-induced failures. The specs of this first SSD reflect these ambitions, but perhaps not in quite the way people would have expected.

The 2,400MB/s read speed is high, but it’s not king of the hill. Introduced in 2014, Intel’s SSD DC P3700, the company’s nearest equivalent product using NAND flash technology, boasts up to 2,800MB/s reads. Samsung’s consumer-oriented 960 EVO manages 3,200MB/s read performance.

Dolby Cinema: Twin laser projectors + object-based 3D audio = awesome

(credit: Iljitsch van Beijnum)

Earlier in the year, our own Sebastian Anthony had the opportunity to experience the new “IMAX with laser” cinema in Leicester Square, and it didn’t disappoint. Not to be outdone, Dolby Laboratories invited Ars UK to the new JT cinema with Dolby Cinema in Hilversum, the broadcasting capital of the Netherlands.

Middle-aged Ars readers may remember Dolby from the Dolby B noise reduction system used with cassette tapes. Younger Ars readers are probably more familiar with Dolby through Dolby Digital, the codec used to encode most digital audio on DVDs as well as TV broadcasts and Blu-ray discs. (Dolby Digital started out as a way to add digital surround sound to film, where the digital information is encoded on the unused space between the perforations of the 35mm film, where it can be read optically.)

The latest Dolby audio technology in cinemas is Dolby Atmos, which supports a few more audio tracks than older systems—128 of them, in fact. However, Dolby Atmos improves upon previous surround sound technologies not by simply adding more channels. Instead, it allows sounds to be dynamically placed in a 3D space. This is used to great effect when noisy objects fly over the audience; it sounds very realistic. To allow for these effects, the JT cinema in Hilversum has no fewer than 60 speakers on the walls and the ceiling of its Dolby Cinema-equipped auditorium. Dolby Atmos is currently installed in several thousand cinemas worldwide and films such as Spectre and the new Star Wars are available with a Dolby Atmos mix (in compatible cinemas).

Cisco Aironet APs + vinyl = awesome

Sure, white makes sense most of the time for a wireless access point, which is probably why the Cisco Aironet line comes in that color and no other (near as I can tell).

However, this state of blandness didn’t sit well with Markus Räty, a systems specialist in the NOC at University of the Arts Helsinki. Räty recently posted this message to the section of Reddit devoted to networking:
