The Barefoot controller was designed in
Korea and is built on a 90nm process. It features TRIM support and
64MB of DRAM cache. The controller can be used for SSDs as large as
512GB. The fastest SATA SSD using the controller is OCZ's
Vertex Turbo, with a maximum read speed of 270 MB/s.
SATA II interface that the Barefoot controller uses is only capable
of 300MB/s. With protocol overhead factored in, the real world
performance of SSDs is already limited when reading from cache,
leading many SSD
manufacturers to create PCIe-based solutions.
New types of
flash like the DDR
MLC NAND recently announced by Samsung will allow much faster
read and write speeds with the next generation of SSDs. Motherboards
supporting a 6Gbps
SATA interface are already available.
Indilinx has been
working on its next generation Jet Stream controller featuring
6Gbps SATA and DDR NAND support for over a year. The new controller
is supposedly being designed for a 65nm process, and can be used for
SSDs as large as 1TB.
DailyTech has learned from
several industry sources that the new controller will begin
sampling in the first quarter of 2010; though it was supposed to
be sampling already. The first production batch of SSDs using the new
controller likely won't be ready until the second quarter.
news is just the latest setback to enthusiasts looking for a SSD
upgrade. SSD prices have risen dramatically over the last six months
as NAND flash prices have doubled. Strong demand for products using
flash like SD cards, SSDs, and portable media players is to
Enthusiasts shouldn't despair though. New SSD
controllers from Samsung
may be available soon, while Micron has just
announced the first 6Gbps SSD using its own proprietary
controller and firmware.
