Samsung creates F2FS file system for NAND flash storage, submits it to the Linux kernel

Has the lack of NAND flash storage-optimized file systems been bugging you? Then you’ve got something in common with Samsung, which has developed F2FS (or “Flash-Friendly File-System”) for the memory of choice for mobile devices and its specific “internal geometry.” It’s based on a log-structured method, but tackles problems associated with older file systems intended mainly for retro, spinning-disk storage. The company isn’t keeping its hard work behind lock-and-patent either — it’s gone open-source and submitted the file system to the Linux kernel, meaning you could see it implemented in Android hardware of the future. It’s nice to see Sammy contributing code for the greater good, and if you’ve got the skills to understand it, a low-down of F2FS is available at the source below.

PQI announces USB3.0 U822V Speedy

The Foxlink Group’s Power Quotient International (PQI), the world leader in wireless storage devices, initiated a race for speed today by officially announcing the launch of the Intelligent Drive U822V Speedy portable USB flash drive. PQI USB3.0 U822V Speedy offers exceptional speed. Compared to the traditional USB2.0 interface, a read speed of 88MB/Sec translates to an increase of 293%, while a write speed of 66MB/Sec is a 330% increase. It is akin to the incredible speed one experiences …

Nintendo Wii U expandable memory explained, TiVO hardware not built in

The Nintendo Wii U may only have 8 to 32GB of internal memory, but the company’s taking a decidedly open approach to expanding that memory: add your own. “You can plug in a full-on three terabyte hard drive if you want. I’ll love you as a digital consumer,” Nintendo America CEO and president Reggie Fils-Aime told us during a post-press conference investor Q&A. Much like Sony’s PlayStation 3, the Wii U allows for expansion of memory via USB, whether that memory be Flash or otherwise. Fils-Aime explained that, with the continuously dropping price of memory, there was little reason to offer pricing for the Wii U — available in $300 and $350 — tied to an evolving hardware model.

“The reason we did it that way is that the cost of that type of storage memory is plummeting. What we didn’t want to do is tie a profit model to something that’s gonna rapidly decline over time. We’ll let the consumer buy as much as they want, as cheaply as they want,” Fils-Aime said.

Fils-Aime also confirmed that the Wii U doesn’t have TiVO hardware built into it — functionality will require an existing TiVO box. The same goes for DVR functionality, which Fils-Aime said Nintendo doesn’t want consumers to bear the expense of.

Fujitsu and Acacia resolve patent disputes with settlement, keep it out of the courts

Fujitsu and Acacia resolve patent disputes with settlement, keep it out of the courtsFujitsu’s bank balance may be a little lighter today, since Acacia Research Corp. has reported that subsidiaries of both companies have signed a settlement deal over patent disputes. As usual, Acacia is keeping tight-lipped about exactly what the patents cover, but a little digging on our part has revealed they are related to flash memory and RAM technologies. The agreement resolves lawsuits in the works at district courts in Texas and California, which is probably a good thing. After all, these cases can get pretty messy when they go to court.

Samsung’s New Superfast Chips Could Fuel Your Future iPhone [Guts]

Samsung starts mass-producing 4x faster mobile flash memory, kickstarts our phones and tablets

Samsung starts massproducing 4x faster mobile flash memory, kickstarts our phones and tablets

Samsung isn’t content to leave fast NAND flash memory to traditional solid-state drives. Its Pro Class 1500 promises a big jolt to the performance of frequently pokey smartphone and tablet storage. By how much? That name is a clue — it reaches 1,500 IOPS (inputs/outputs per second) when writing data, which along with 3,500 IOPS data reads is about four times faster than any previous embedded flash chip Samsung has tested. In the real world, that leads to as much as 140MB/s when reading data and 50MB/s for writes. The speed comes after Samsung has thrown virtually every trick in the book at its new chips, including a dense 20-nanometer manufacturing process, quick toggle DDR 2.0 memory with its own controller and a new JEDEC memory standard with 200MB/s of bandwidth to spare. Samsung hasn’t named customers for the 16GB, 32GB and 64GB parts that are rolling out of the factories, although we’d do well to remember that a flourishing phone business doesn’t guarantee that the only major customer is Samsung itself: even in the face of legal challenges, Samsung still has at least one noteworthy client that tends to snap up much of its flash supply.

Lexar XQD memory cards announced, will duel with Sony for Nikon D4’s attention

Lexar XQD memory cards announced, will need to duel with Sony for Nikon D4's attention

Nikon’s D4 is currently the only belle at the XQD ball, and until now, Sony was its only memory suitor. However, Lexar’s just arrived with a new line of cards to compete for the D4’s affections. The Fremont-based company says it collaborated with Nikon to build the PCI Express-based memory, and that they’ll hit the market sometime in the third quarter of 2012 — with no mention of specs or prices so far. Unfortunately, that means we don’t know how Lexar’s offerings will stack up against Sony’s H-series or S-series cards already on the market. That said, while you wait for more details about Lexar’s new cards, feel free to check out the lovely data the D4 will be putting on ’em when they arrive.

Sony S-Series XQD memory cards hit speed record at 168MB/s, starting at $500 for 32GB in Japan

sony-xqd-memory-card-speed-record-168mb-s

Sony’s new S-Series XQD memory cards will be the fastest you can buy when they arrive on the Japanese market July 11th, with a transfer speed of 168MB/s — a boon if you’re shooting continuous raw photos or high data rate HD video. The company claims that you’ll need a Thunderbolt connection on your computer to take advantage of all that speed, which comes via the PCI Express Gen interface used for the memory cards. The 32GB and 64GB models will also have plenty of space to put all that media, but you’ll need to pay for the privilege, to the tune of $503 and $754, respectively. Of course, those prices may not be an issue if you’ve already plonked down the coin for one of the few devices that support them.

Seagate and DensBits team up on solid-state drives for the home, call truce in the HDD versus SSD war

Seagate Pulsar XT 2It’s an understatement to say that Seagate started off on the wrong foot in its attitude towards solid-state drives: the company only slowly came around to embracing flash memory, and then mostly for the enterprise crowd and hybrid drive lovers. A newly-struck partnership between Seagate and controller maker DensBits is signalling a more serious attempt to offer SSDs to everyday users. Along with catering to the business folk, Seagate wants its new teammate’s help on building “low-cost, high-performance” consumer SSDs. Most of the drives for the plebeians will use slower but denser 3-bits-per-cell memory made on a process under 20 nanometers, while the suits will get faster 2-bits-per-cell flash for their servers. The deal doesn’t have any timetable attached, although Seagate’s decision to pour equity cash into DensBits suggests it’s not just a one-time fling.
