[zamoth]

OCZ announced its Z-Drive PCI Express solid state disks are now available. The memory company introduced two versions: the SLC-based e84 and the MLC-based p84. The Z-Drive e84 ships in 256GB and 512GB capacities, it features read speeds of up to 800MB/s, write speeds of up to 750MB/s and up to 16,000 IOPS (4k random write). The Z-Drive p84 is available in 256GB, 512GB and 1TB capacities, this model promises read speeds of up to 750MB/s, write speeds of up to 650MB/s and 10,000 IOPS (4k random write).

OCZ Technology Group, Inc., a worldwide leader in innovative, ultra-high performance and high reliability memory and flash-based storage as an alternative to hard disk drives (HDDs), today unveiled the Z-Drive, a PCI-Express Solid State Drive (SSD) designed to meet the stringent demands of enterprise computing clients. Unlike other solutions, the Z-Drive provides a cost-effective formula of performance, reliability, and upkeep for enterprise customers and their applications which require the benefits of solid state drive technology, but have previously been hesitant to adopt competing products due to the sheer cost of implementation. “Traditional enterprise storage technology typically requires overly complex infrastructure as well costly maintenance, and is often unable to deliver the level of performance required by OEM applications,” said Ryan Petersen, CEO of the OCZ Technology Group. “The new OCZ Z-Drive is an all-in-one high performance plug-and-play bootable PCI-E solid state drive that addresses these challenges head on, and meets the demands of the complete range of enterprise storage and data access requirements. The Z-Drive is designed not only to be higher performing and more reliable than conventional solutions, but also to significantly reduce both the maintenance and overall TCO for our clients.”

The Z-Drive is the result of the latest breakthroughs at OCZ and builds on the company’s expertise in flash-based storage. This proprietary SSD is bootable and takes the SATA bottleneck out of the equation by employing a high-speed PCI-Express architecture coupled with a compact enterprise-grade RAID array. With 8 PCI-E lanes and an internal four-way RAID 0 configuration, the Z-Drive delivers exceptional performance that translates to professional-class data storage in a complete, all-in-one form factor. Additionally, OCZ offers unique customization options for OEM clients that may require tailored hardware or firmware solutions for their business.

In addition, these impressive speeds are achieved all while providing lower power consumption, superior durability, and shock resistance compared to traditional rotational-based drives, translating into exceptional energy savings and reduced maintenance costs.

An ideal solution for enterprise clients that put a premium on both performance and maximum storage capacity including servers, storage arrays, supercomputing, professional media, and industrial electronics, the Z-Drive is available in 256GB, 512GB, and 1TB (p84 only) capacities to offer ample room for the complete spectrum of applications. The Z-Drive comes backed by a leading 3-year warranty and dedicated technical support, ensuring unparalleled peace of mind.

So this is a hard drive that use on PCI express slot?

So this is a hard drive that use on PCI express slot?

yes need PCIe 4x i add some information of all PCIe


In July of 2002 PCI-Express was approved, and in mid 2004 we started seeing deployment on Intel based motherboards, with the nForce4 and K8T890 adding AMD support later in the year. Why PCI-Express you ask? Wasn't PCI/AGP enough bandwidth for our ever increasing desire to move things along faster? Well, PCI Express is here to alleviate some short comings in the PCI world and to satisfy our ever increasing need for BANDWIDTH...

PCI (Peripheral Component Interconnect) was originally developed by Intel Corporation, but is now slowly coming to an end, by slow I mean it wont be discarded for a couple of years yet. PCI 2.2 bus and other revisions/iterations just don't provide us with enough bandwidth to support the increasingly bandwidth hungry and demanding peripheral cards. Hard drive controllers and networking cards just aren't provided enough bandwidth that some hard drives have the potential to offer.

The reason is because PCI only offers a throughput (maximum theoretical bandwidth) of 1.056Gbps while Serial-ATA hard drives can offer a maximum of 1.5Gbps (3.0Gbps with SATA II); however, if a SATA controller can only have a transfer rate of 1.056Gbps, the SATA drive will have a transfer rate of only 132MBps (megabytes per second), which is roughly equivalent to ATA-133 technology. This is true if there are no other peripherals requesting use of the bandwidth. PCI shares that 132MBps bandwidth as it only uses one PCI bus which is connected in parallel. Although there are other PCI versions available, most motherboards and components use the 32-bit PCI which operates at 33MHz.

Now for all of you with the Gigabit LAN cards must realize that at 1000Mbps you are using approximately 95% of your available PCI bus' bandwidth. This leaves little room for any other peripherals to use bandwidth. Currently the primary user will be using the Sound Card, Hard Drive and LAN on the PCI Bus, this could cause transfer issues, sound clipping and HD transfer interrupts. While most of us probably find PCI to be satisfying, we are rapidly approaching the point where PCI just won't be enough for our needs. Therefore, I present to you PCI-Express.

Bandwidth: AGP vs. PCI vs. PCI Express

PCI-Express should provide ample bandwidth for scalability well into the decade and perhaps even further. Currently, PCI-Express comes in five formats:

x1, x2, x4, x8, x12, x16. x4, x8, and x12 are likely to be reserved only for the server market while x1, x2, and x16 remain for the consumer for now.

Note: Each lane is comprised of 4 pins; x1 has one lane, x2 has two lanes, x4 has four lanes, and so forth. PCI-Express can transmit 100MB per second per pin.

Input/Output Bus Systems: [ISA = Industry Standard Architecture, EISA = Extended ISA, VLB = Video Electronics Standards Association (VESA) Local Bus, PCI = Peripheral Component Interconnect, AGP = Accelerated Graphics Port]





This is what the PCI-Express slots look like (excluding x2). These slots are attached to a switch (yes similar to that switch in your network) that controls the data flow. This is an improvement over a shared bus because each device pretty much has its own direct access to the bus instead of multiple components having to share the bus. This allows each device to use its full bandwidth capabilities without having to compete for the maximum bandwidth offered by a single shared bus. Then you add in the lanes of traffic that each device has access to then one can truly control much more bandwidth than previous PCI technologies. As mentioned before, x1 has one lane of traffic which is divided into input and output, obviously. Each lane is capable of providing approximately 500MB/s of bandwidth in both directions.

Eventually, x32 and possibly x64 slots will be realized for PCI-Express, but those probably won't be seen for a good while. Those slots are likely to be used for highly-demanding graphics cards. For now, desktop users will most likely see x1, x2, and x16 slots along with previous PCI slots on their motherboards. The following is a summary of PCI-Express:

• Much higher scalability over PCI bus
• Initially advantageous for hard drive controllers, gigabit LAN cards, and other bandwidth intensive devices
• Not necessary for a graphics upgrade as AGP 4x and 8x provide ample bandwidth for today's and tomorrow's Games. Games requiring the large amount of bandwidth PCI-Express x16 offers will likely be released in 2006.
• Not to be the ultimate deciding factor of a current system build as PCI and AGP should provide enough performance for your system unless you require gigabit LAN and other bandwidth-demanding peripherals.
• PCI-Express is still in its infancy and drivers and revisions will periodically be upgraded.

Cool!! but yet i got only one PCI-express slot that is my graphic card is using
