Indilinx scores a big win from OCZ

OCZ Technology has traditionally used Solid State Drive (SSD)controllers from JMicron for its multi-level cell (MLC) SSDs. The controller and firmware used can mark a large difference in performance and long-term reliability.

DailyTech has been able to confirm that OCZ will use a version of the Barefoot SSD controller from Indilinx for the first time in its Vertex series of SSDs. Indilinx is a fabless semiconductor company specializing almost exclusively on SSD controllers and SSD technologies. It is backed by venture capital firms Softbank Korea Investment and MVP Venture Capital.

Its business operations are centered on the city of Milpitas, California, in Silicon Valley. It's also home to the corporate headquarters of SanDisk, LSI Logic, Adaptec, Promise Technologies, and Maxtor. Seagate and Western Digital also have a large presence in the area. However, Indilinx's main Research and Development center is in Seongnam, Korea.

The first Barefoot controller we saw in August last year was built on 90nm process technology, with a very fast read speed of 230MB/s and support of up to 512GB of MLC NAND flash using at least four channels. Indilinx classifies it as a second generation SSD controller, meaning it has maximum read speeds over 200MB/s and maximum write speeds over 150MB/s, using a native SATA controller.

The Barefoot controller is notable for using up to 64MB for data buffering, surpassing traditional hard disk drives. It also features ECC capability of more than 12 bits per sector to ensure reliability, with hardware implementations of both Reed-Solomon and BCH (Bose Chadhuri Hocquenghem) Error Correcting Code.

Indilinx is currently focusing on its third generation controller, codenamed "Jet Stream". It will feature ONFI 2.0 support and a SATA 6Gb/s interface, providing throughput of up to 600MB/s, with a target release date in the third quarter of 2009. Both Intel and AMD are working on new chipsets that will support 6GB/s.

OCZ will soon release its highly anticipated Vertex series of drives at a lower price than originally announced in December due to lower component acquisition costs and lower than expected production costs. Their 120GB and 250GB models will exhibit faster speeds due to the fact that the controller has access to a greater number of channels, providing a significant boost to read and write speeds over what was previously announced. These drives feature 64MB of cache, while the 30GB and 60GB models will have 32MB of cache.

Intel recently lowered prices on its lineup of SSDs, which feature an SSD controller designed by Intel itself. Competition has been fierce from drives like the G.Skill Titan and OCZ Apex series of second generation SSDs.

Delays to the Vertex line have been primarily due to firmware optimizations. According to sources inside OCZ, the company wanted to use the best version possible in all of its drives, rather than having end users perform it themselves or ship several different versions of firmware as is common in the hard disk drive industry.

Their latest version of firmware has been highly tweaked for performance and reliability. Wear-leveling algorithms are especially important in MLC SSDs in order to maintain long-term performance and write reliability.

Seagate, the world's top hard disk drive manufacturer, has been rocked by multiple firmware problems across its entire Barracuda 7200.11 product series, shaking its previously sterling reputation. Seagate's leadership has also been criticized for not responding to the performance threat posed by SSDs to sales of their 15k Cheetah and Savvio enterprise drives.

OCZ is currently updating the firmware of Vertex drives it has already produced. It was hesitant to provide a firm shipping date, but stated it would be out by the end of February. Initial shipments could be out as early as next week pending quality assurance testing, with retail availability several days after.

With better performance, higher reliability, and a lower price, the delay may well be worth the wait.

It's largely a firmware/controller issue. All of the cheap MLC drives used an equally cheap controller from Jmicron. It's probably why OCZ is throwing out press releases about their new manufacturer of controllers.

Anandtech looked at the controller issue here

This article was written because I took the initiative to talk to a couple of people and ask some questions. It is NOT some rehashed press release from OCZ, as you are insinuating.

OCZ has not been throwing out press releases about their controllers, they are quite happy with JMicron. The reason they went with Indilinx is bacause of the cache.

Read to find out more about the updated JMicron solution:

We were told in the OCZ forum that Anand got some Vertex in hand.

My guess is that you were surprised by the speed it offers so you wrote an article :D

Do I detect a bit of attitude? 8)

Well written article.

Any chance you have more performance info, over varying load conditions? I've seen some initial numbers, but would like to find out more on where the strengths and weaknesses are. And how would Vertex SSD's do in RAID? etc.

Press releases are spin documents put out by marketing departments. Their job is to sell you on a product.

My job is to provide more information so that DT readers can judge for themselves.

If I'm interested in something, I'll write it up. If it is boring or biased, I'll do my own spin. If it's a crap product, I can't be bribed to write about it.

Total coolness. And, again, an excellent job you have done. Having a passion for what you do really shows through to the reader, and in a sense makes it easier to defend your points.

I was thinking something along the lines of comparing the Vertex SSD to this ...

four x-25E's in RAID. Not so practical but I bet we've all thought about it, and the information content is very useful. As in, don't bother, due to marginal performance gains; your neighbor Mr. I.M. Rich does not win, since you've got to put a system together intelligently, not just simply throw money at the system.

Maybe the Vertex SSD does better - price/performance wise -because of the new controller?

Hi Mr Perfect,

Since this is my first post in this article I'd like to identify myself as an employee with OCZ. First, thanks for your comments, I can understand how concerns regarding controllers can arise. We are always looking for new options to improve performance and value in our SSD lineup.

In this case we did not release any information about our controller choice in the Vertex. In fact Janson had to really dig for the information, and it was only after we realized he already had more information than we originally thought did we confirm some of the facts that he had already discovered.

We are excited about this solution and will continue to release new drives as new controllers become available, we want to be able to offer customers the latest solutions based on the most up to date technology available.

You are dealing with Intel ppls here at anand :(

we dont get any solid reviews of any ssd setup that is not intel. We all know that is just the way it is. lol

We could not even get a review of a caching controller and a few cheap ssd drives that came to $500+ for the cost of 1 60gig intel ssd months ago.

Well I hope you manage to get a review posted on anand that is all fair and logical.

by that i mean. few cheap(broken controller) drives raid 0 on a sata card with ram. totalling $500 ish max.

then compare the speed/reliability. to a single intel M drive for the same money.

Yes it's a pet rant. intel have best production tech to make cheaper MLC/controller than rest of ssd market then charge $200+ above rest of market for what? A good controller.

I guess the logic that every $ you take from a punter. Is a $ less they can spend with your rivals. Is not well understood at intel :(
