WD And Sandisk Join Forces
Western Digital and Sandisk have teamed up to create Western Digital’s first hybrid storage device that uses Sandisk’s iSSD and Western Digital’s Caviar Black hard drive.
Western Digital, which has dabbled in solid state disks (SSDs) for the enterprise market, has stayed away from hybrid drives that use relatively small SSDs to act as cache for hard drives. Now the firm has teamed with Sandisk to create its WD Black Solid State Hybrid drives with 500GB capacity.
Western Digital is pitching its hybrid drives at laptop makers, offering units with 5mm, 7mm and 9.5mm heights. The firm said Sandisk’s iSSD uses 19nm NAND flash and claimed it is the world’s “smallest and most advanced semiconductor manufacturing process”, a claim that Intel might question.
Kevin Conley, SVP and GM of client storage solutions at Sandisk said, “By combining SanDisk’s unparalleled flash memory expertise and technology with the hard drive know-how of Western Digital, WD Black SSHDs [solid state hard drives] offer outstanding hard drive-like capacity, and the slim form factor and the level of performance that you will only get with flash memory solutions.”
Seagate was first to introduce hybrid drives with its Momentus XT range, which offers an impressive performance boost over mechanical hard drives for certain workloads. The problem for Western Digital and Seagate is that hybrid drives are merely a stop-gap rather than a long term strategy, with SSD prices falling rapidly due to competition in the SSD industry as opposed to the hard drive industry, where Seagate, Western Digital and Toshiba have a comfortable ride.
Is Non-Volatile Memory The Next Craze?
A report from analysts Yole Developpement claims that MRAM/STTMRAM and PCM will lead the Emerging Non-Volatile Memory (ENVM) market and earn a combined $1.6bn by 2018. If the North Koreans have not conquered America, by 2018 then MRAM/STTMRAM and PCM will surely be the top two ENVM on the market.
Yole’s Yann de Charentenay said that their combined sales will almost double each year, with double-density chips launched every two years. So far we have only had FRAM, PCM and MRAM to play with and they were available in low-density chips to only a few players. The market was quite limited and considerably smaller than the DRAM and flash markets which had combined revenues of $50bn+ in 2012, the report said. In the next five years the scalability and chip density of those memories will be greatly improved and will spark many new applications, says the report.
ENVM will greatly improve the input/output performance of enterprise storage systems whose requirements will intensify with the growing need for web-based data supported by cloud servers, the report said. Mobile phones will increase its adoption of PCM as a substitute to flash NOR memory in MCP packages thanks to 1GB chips made available by Micron in 2012, it added. The next milestone will be the higher-density chips, expected in 2015, will allow access to smart phone applications that are quickly replacing entry-level phones.
Super Talent Outs New SSDs
Super Talent has announced a new line of SATA III SSDs, the Super Talent SuperNova. Aimed at the business market, SuperNova SSDs will be available in 128 and 256GB capcities.
Although it has not announced any details regarding the new SuperNova lineup in its official press release, Super Talent did note that SuperNova features high transfer speeds and “the most secure encryption” on the planet, as well as the proprietary RAISE technology that virtually eliminates unrecoverable read errors.
After some digging around we managed to find that SuperNova is based on Sandforce SF-2200 controller paired up with ONFI Synchronous MLC NAND chips that should provide enterprise level of reliability. The sequential performance is set at 555MB/s read and 525MB/s for write while random 4K performance is at 90K IOPS read and 85K IOPS write, for both 128 and 256GB models.
Adata Outs 40MB/s UHS microSD Card
Adata has launched a 32GB UHS-1 microSD card offering 40MB/s write bandwidth.
Adata, which recently has been making a big push in the solid-state disk (SSD) drive market, has announced its first microSD cards that support the UHS-1 specification. The firm’s Premier Pro cards come in 8GB, 16GB and 32GB capacities with the firm citing read bandwidth of 45MB/s and all important write bandwidth of 40MB/s.
The SD Card Association defined the UHS-I specification as part of its SD Version 3.01 standard, and while Adata’s new cards boast impressive speeds there is a lot of headroom left, with UHS-1 supporting bandwidths up to 104MB/s. Adata’s cards, roughly translated to the ‘X’ speed rating used on a number of memory cards, come out at 266X.
Ray Chu, product manager at Adata said, “These cards have the best read and write performance among all comparable products offered by the industry’s key players. When that is combined with the aggressive pricing options in store for this line, the result is going to be a bonanza for our customers worldwide.”
