Swiss boffins unleash power of graphene on flash mem

A Swiss government research lab has reinvented flash memory using graphene and molybdenite in a way that should be faster, scale smaller, use less energy and yet more flexible than boring old NAND. Molybdenite is MoS2, molybdenum disulfide, which is similar to graphite and also has a lubricating effect. Atomically it is a …

The HP 3PAR StorServ 7000 series arrays

HP: Flash is better in than out. Better for us, er, our customers

HP is going to implement its all-flash arrays inside the StoreServ (3PAR) architecture and operating environment. This sets it at odds with every other all-flash array supplier and other believers of external flash silos. Of course there's also the added benefit that this tactic may prevent HP's StoreServ customers from buying …
