 OCZ announces the Indilinx Everest

OCZ has just officially announced the Indilinx Everest. Based on the new generation SATA 3.0 controller previously known as Jet Stream, then Thunderbolt, which was supposed to be out as of 2010, Everest should allow Indinlinx to get back in the race.


Everest is made up of a dual core ARM CPU with a DDR3 cache at 400 MHz of up to 512 MB. It supports an SATA 6 Gb/s interface and has been designed for sequential speeds in the order of 500 MB/s for a total capacity of 1 TB maximum. These speeds are achieved with the help of 8 channels of Flash ONFI 2.0 / Toggle 1.0 Flash at speeds of up to 200 MT/s, while other controllers are limited to 166 MT/s.

OCZ says moreover that Everest is optimised for 8 KB pages that are found in recent flash memory and that it uses algorithms that have been specifically designed to reduce start-up times, with a gain of up to 50% on current SSDs, a figure to be taken with a pinch of salt as things stand.

Everest also stands out for its flash memory support, with 1xnm class memory already admitted, no doubt the 19nm memory recently announced by Toshiba as well as support for SLC, MLC and TLC memory. Also know as MLC 3BPC, TLC memory allows you to store 3 bits per cell. This makes for a significant reduction in production costs as the 25nm 8 GB chip announced in August 2010 by Micron is 21.5% smaller than standard MLC. However, its true value is questionable, with Micron itself holding back on using it in its SSDs, speaking since the beginning of 2009 of performances halved and lifespan divided by ten in comparison to MLC.

Things may have changed in this respect since then and OCZ says that Everest includes a proprietary technology, Ndurance, which is supposed to allow the use of memories with reduced lifespan. No details have unfortunately been given on Ndurance and all we know is that Everest uses error correction technology based on the BCH algorithm that can reach over 70 bits per 512 bits, where the SandForce SF-2000 is limited to 55 bits.

The Indilinx Everest platform is currently available for OEM qualification, with OCZ not giving any information on any future SSD based on the Indilinx Everest under its own brand. Although these raw performance levels aren’t likely to turn the world of SSDs upside down, TLC support, the integration of a specific algorithm on start-up and the Ndurance technology will nevertheless garner plenty of interest… we can’t wait to see all this in practice!

Crucial are currently the only manufacturer to market an affordable “new generation” SSD with the M4 64 GB. How does it do compared to its predecessor, the C300 64 GB and the C300 M4 128 and 256 GB models?

 A miracle firmware for Indilinx?

OCZ, who recently bought Indilinx, has just announced a new generation Indilinx firmware, code name Arowana. Running on both current Indilinx controllers such as the Barefoot and forthcoming ones such as the Jet Stream (castle in the air?), this new firmware has been announced as very promising.


Among the new features, OCZ is talking about HyperQueuing, which would allow sequential write gains and in random accesses support for 25nm memory as well as a technology known as INXtend that is supposed to improve the lifespan of reduced endurance flash chips.

No specific details are given but HyperQuening may well put an end to the slowdowns experienced with Barefoots in terms or random accesses, notably in writes on more recent controllers.

This would be very good news for those who own an Indilinx SSD, especially as the firmware will not be exclusive to OCZ. It only remains for Indilinx to bring out a new SATA 6G controller to confirm that it’s really back in business!



 SSDs at $1/GB end 2012?

Gartner have just published a few predictions with respect to SSD pricing. Reported by PC World, they indicate that while SSDs are starting to make more of an impact on the enterprise market, adoption by the general consumer is still limited by pricing. Gartner are predicting a 30% fall in SSD pricing this year and another 36% next. This would give us a price of $1 per GB for the second half of 2012. Currently the price per GB of an SSD such as the Crucial M4 256 GB is $2.03/GB on the other side of the Atlantic (VAT not included).


Several factors will come into play including an improvement in fabrication processes and an increase in production to respond to demand. While the price of chips may well be coming down this is not necessarily immediately reflected in the price of SSDs to the consumer. Few manufacturers have significantly reduced pricing following the movement from 34/32/nm to 25nm for example, with the trend actually going in the other direction on launch.
