Samsung adds USB 3.0, 7200RPM rotation to S2 portable HDD
Samsung has updated its S2 portable hard drive line, adding a quicker interface and spindle speed. The series was bumped to 640GB last year, and this refresh doesn't seem to change anything capacity-wise. However, the company has dropped USB 2.0 in favor of USB 3.0 connectivity.
That probably won't affect real world transfer rates much (if at all), but Samsung says "the on-board USB technology reduces the size of the hard disk casing and delivers reduced power consumption." What will boost performance is the drive's quicker 7200RPM rotation (up from 5400RPM).
The 2.5-inch S2 Portable 3.0 drives come preloaded with software utilities including Samsung Auto Backup, as well as SecretZone and SafetyKey for data encryption and password protection. Both 320GB and 640GB units will begin shipping this month in Europe. Word is mum on pricing and US availability.

SanDisk unveils stamp-sized 64GB SSD
SanDisk has revealed a new class of solid-state drives that supposedly offers more speed and storage than any competing solution. The firm's integrated SSD or "iSSD" crams up to 64GB of memory into a BGA package measuring 16mm x 20mm x 1.85mm and weighing less than one gram. In more relative terms, SanDisk says that's about the size of a postage stamp and lighter than a paperclip.
Performance-wise, the iSSD peak at 160MB/s sequential read and 100MB/s sequential write rates, which isn't far behind most full-size 2.5-inch SSDs. It actually surpasses a handful of the budget drives listed on Newegg, and it's rather speedy for storage that is largely aimed at compact devices such as smartphones as well as tablets, portable media players, netbooks and smartbooks.
Samples of the iSSD are currently shipping to OEMs in capacities from 4GB to 64GB. The press release notes that pricing is dependent on the order quantity, but avoids mentioning any numbers. The company didn't say when its new drive will enter mass production, nor did it spill the names of any buyers, but you can bet Apple and other large players are preparing their checkbooks.

Rumor: Nvidia GeForce GT 430 coming in a few weeks
After a less than stellar debut of the Fermi architecture Nvidia finally won us over in the $200 price segment with the GF104-based Geforce GTX 460 graphics card. We've heard a flurry of rumors about lower-end (read: more affordable) derivatives for quite a while, and now, Fudzilla brings word of the latest rumored addition to the lineup: the GeForce GT 430.
The new card will reportedly arrive "in a few weeks" featuring a 700MHz core clock speed, a 900MHz memory clock, and a 128-bit memory interface. Although the number shaders is not mentioned, the GT 430 is most likely to be based on the GF108 graphics core, which is believed to sport 96 shader processors and should be targeted at the sub-$100 market. That said, Fudzilla is still trying to find out whether the card will be a retail product or an "OEM only" card available in pre-built PCs.
Other products reportedly in the pipeline include a 512 SP card based on the original GF100 core, as well as the GTS 450, 440, and 445 cards powered by the mainstream GF106 chip, with the GTS 450 expected to arrive in mid-September.
