OCZ's new top of the line SSDs use Samsung controllers

OCZ Technology is currently one of the top Solid State Drive manufacturers in the world. They have been aggressively developing new SSD products and bringing them to market, and can be credited for driving prices down through mass production and economies of scale.

As the company has never been afraid to experiment, they have tried prototypes with SSD flash controllers from different manufacturers. JMicron controllers are amongst the cheapest, so they go in lower end SSDs such as the Core and Solid series. The mid-range Apex series uses a JMicron RAID controller along with their flash controllers to improve performance. The high-end Vertex series uses a new flash controller from Indilinx that utilizes 64MB of cache to improve random read/write performance.

OCZ is currently developing their newest SSD series and will target it at the "premium" market. The Summit series uses a controller and firmware developed by Samsung. It also uses 64MB of cache to improve random read and write performance.

Sequential read speeds are expected around the 250MB/s range, while sequential write speeds are expected to be in excess of 200MB/s. Figures for random read and write speeds are currently unavailable, but those are increasingly becoming looked at by educated consumers as they more accurately represent real-world usage models. The firmware is still being tweaked, so performance numbers have not been finalized.

The design is similar to Samsung's own 256GB SSDs, which are currently available only to OEMs (Original Equipment Manufacturers). Power consumption for the Summit series should be also comparable, using around 1 watt at load. There will be 30GB, 60GB, 120GB, and 250GB models.

The Summit series is currently targeted for launch around the end of April. Pricing is expected to be moderately above the Vertex series, which has dropped dramatically in price over the last month. The 120GB Vertex model can now be purchased for around $300 with a mail-in rebate.

"
Ryan said we’d lose some sequential write performance. The drive would no longer be capable of 230MB/s writes, perhaps only down to 80 or 90MB/s now. I told him it didn’t matter, that write latency needed to come down and if it were at the sacrifice of sequential throughput then it’d be fine.
...
A couple days later and I got word that OCZ just got a new firmware revision back from Korea with the changes I’d asked for.
...
I couldn’t believe it. There was no way. “Sure”, I said, “send the drive over”. He asked if I’d be around on Saturday to receive it. I would be, I’m always around.
...
As far as I know, this is the one of the only reviews (if not the only) at the time of publication that’s using the new Vertex firmware. Everything else is based on the old firmware which did not make it to production. Keep that in mind if you’re looking to compare numbers or wondering why the drives behave differently across reviews. The old firmware never shipped thanks to OCZ's quick acting, so if you own one of these drives - you have a fixed version.
...
The entire production of Vertex drives was held up until they ended up with a firmware revision that behaved as it should.
"

So OCZ's Vertex line supposedly shouldn't suffer from the silly stuttering problems of the past - due to companies optimizing for pro-marketing seq. transfer numbers instead of more real-world random access stuff.

Looks like OCZ's Vertex and Summit product lines should finally give Intel's products some pressure in the closer to mainstream segment.
