New SATA interfaces promise faster, smaller SSDs

SATA Express and µSSD specs announced
The Serial ATA International Organization has announced two new specifications for its humongously popular SATA interface - SATA Express and µSSD.
The SATA Express specification piggybacks the PCI Express interface to enable epic device speeds of 8Gb/s and 16GB/s - a marked increase on the current maximum of 6Gb/s.
The new specification is expected to be low-cost, and will support both current and new SATA devices.
"We expect the SATA Express specification to be completed by the end of 2011," said Mladen Luksic, the SATA-IO president.
Embed with Sandisk
The keyboard-challenging µSSD interface allows small SSD chips to be embedded directly on the motherboard itself.
By completely eliminating the standard SATA connector motherboards can be made more compact and far slimmer - a big advantage for the small motherboards that currently occupy laptops and tablets.
Memory manufacturer Sandisk has already started making its postage stamp-size iSSD chips in 8GB to 128GB flavours.
What's not clear is whether or not the chips will be consumer-upgradeable - we're guessing that they'll be soldered directly onto the motherboard itself.
This could make the µSSDs very appealing to certain console manufacturers, who'd rather their consumers didn't swap their tiny hard drives for far bigger ones.
