OCZ enters yet another market, jostling with Fusion-IO and Super Talent for enterprise and enthusiast dollars

The promise of fast access speeds has lured many enthusiasts over to SSDs already. Maximum capacity is doubling every year, and costs are dropping due to new process technologies being introduced.

One of the most important target markets for SSD manufacturers is enterprise customers. They are demanding the fastest access speeds possible, whatever the cost. SSDs are often used in a tiered storage scenario, replacing short-stroked 15k RPM mechanical hard disk drives. Even though SSDs are expensive in terms of cost per gigabyte, they offer the greatest performance return for servers due to their fast access times and read/write rates. Power and cooling requirements are also greatly reduced.

OCZ recently launched their Vertex EX series of SSDs in order to compete in this lucrative market, but SSDs are already starting to be limited by the SATA interface. Companies like Fusion-IO, which counts Steve Wozniak on its Board of Directors, have faced the problem by using the PCI-Express interface, which is available using 1, 4, 8, and 16 lane slots on most motherboards.

Super Talent recently announced its RAIDDrive SSD with up to 2TB of storage, but won't be available until June. It uses an x8 PCI-E slot to achieve read speeds of up to 1.2 GB/s, far exceeding the 300 MB/s design limit of the SATA 2.0 specification.

OCZ will compete against the RAIDDrive with its own Z-Drive SSD using a PCI-E 2.0 x4 slot. It will feature a combined 256MB cache managed with an onboard RAID controller. Capacities of 250GB, 500GB, and 1TB will be offered. Maximum read and write speeds vary for each model in the series, although the maximum sustained write speed will be limited to 200 MB/s for all Z-Drives. Random read and write speeds were not made available.

While weighing only 500 grams, the Z-Drive will also save space for power users already looking to RAID Vertex drives. It has a MTBF (Mean Time Before Failure) of 900,000 hours along with a 2 year warranty.

 “It is our goal to deliver tailored SSD solutions for the complete spectrum of high performance applications,” said Eugene Chang, Vice President of Product Management for the OCZ Technology Group.
“Designed for ultra high performance consumers, the Z-Drive takes the SATA bottleneck out of the equation by employing the ultra fast PCI-Express architecture with a RAID controller and four Vertex controllers configured in four-way RAID 0 within an all-in-one product, making this solution ideal for applications that put a premium on both storage performance and maximum capacity.”

Pricing and shipping dates have not yet been announced. However, based on the current cost of Vertex drives, pricing around the $800, $1400, and $3000 marks for the 250GB, 500GB, and 1TB models respectively can be inferred.

"SATA 3" is officially being called "SATA 6 Gbit/s" at the moment and does not reach speeds of 10Gbit/s, but rather 6Gbit/s, making is still much slower than PCIe. Even at its best, SATA 6Gbit still won't match PCIe. I think we are going to see an upset in storage interfaces in the coming years. As companies fight for faster SSDs, they will be FORCED to use PCIe in order to compete with drives like the Z-Drive (as well as similar products coming soon from Patriot and G.Skill).

I don't think "SATA 3" has much a future...

What I really meant to say is "I don't think 'SATA 3' has much of a future as a performance interface." Chances are good that if PCIe storage devices take off, we'll see PCIe controller cards with SATA 3Gbps and eventually SATA 6Gbps ports. So SATA 6Gbps will still have a place, but perhaps only as an internal connection method for PCIe controllers.

That would be awesome if it happened like that...

The problem is that using a controller designed for hard drives, including spin-up times, tolerances, and so on will slow down and limit the speeds of SSD drives that do not have these issues. What is really needed is a new type of interface that is designed with SSD in mind, including the higher transfer rates.

So, how do you deal with this situation if you want to make a high performing SSD other than a dedicated controller card that goes into a slot? You could make a controller with a proprietary connection method, but without standards, who would buy such a thing other than corporations that buy into the idea?

I don't think this is a traditional HDD RAID controller. I have seen no statements or evidence to say one way or the other, but even if it was, it clearly isn't posing a problem for these drives to hit incredible speeds.

Enterprise doesn't use SATA to begin with so that's a non-issue.

There's also 6GB SAS.

allso its gigabit not gigabyte
so its max speed with out overhead is likey to be 500-550MB/s, thats Half the speed of the OCZ vertex Z-Drive can offer

dam thing is very costy thought (id prefer to just get 250gb norm vertex + 1gb HDD)

Gbit/s = gigabits per second.

what about a hard disk drive with multiple sata lanes?
