OCZ unveils PCIe SSD drive; throughput tops out at 800MB/sec

The drives are internally configured for RAID 0

OCZ Technology Group Inc. today unveiled the Z-Drive , a PCI-Express (PCIe) solid-state disk (SSD) drive designed for enterprise-class data centers that boasts throughput speeds of up to 800MB/sec.

OCZ said the Z-Drive is bootable and takes the serial-ATA (SATA) bottleneck out of the I/O equation by employing a high-speed PCIe architecture coupled with a compact enterprise-grade RAID array. The drive has 8 PCIe lanes and an internal four-way RAID 0 configuration to increase performance.

The PCEe interface is currently rated at 500 MB/sec per lane (8Gbit/sec with 8 lanes). PCIe 3.0, to be released in 2010, will have a throughput rate of 1GB/sec per lane. SATA's maximum throughput is currently at 3Gbit/sec., although it is moving to 6Gbit/sec.

OCZ offers customization options for OEM clients that want tailored hardware or firmware options for their business.

"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," Ryan Petersen, CEO of the OCZ Technology Group, said in a statement.

The Z-Drive is available in multi-level cell (MLC) NAND flash memory and single-level cell (SLC) models referred to consecutively as p84 and e84. According to OCZ, the p84 Z-Drive has a maximum sequential read rate of 750MB/sec and a maximum write rate of 650MB/sec and, using a 4KB file size, a maximum of 10,000 input/output per seconds rate. The e84 Z-Drive has a maximum sequential read rate of 800MB/sec and a maximum write rate of 750MB/sec. The e84 Z-Drive can achieve up to 16,000 input/output operations per seconds.

The Z-Drive is available in 256GB, 512GB, and 1TB (p84 only) capacities. The Z-Drive comes with a three-year warranty with technical support.

OCZ did not offer pricing for the drive, which is normally dictated by its resellers.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
