Hitachi announced 3TB Ultrastar 7K3000 enterprise hard drives

New Ultrastar 3TB hard drives offer 7200rpm spin speed, optimsed for 24x7 operation

Hitachi GST has today announced its new Ultrastar 7K3000 enterprise-class hard drives, which are designed for use with 24x7 applications in data centres. The new 3.5in drives feature a capacity of up to 3TB and are claimed by Hitachi to be the "world's first and only" 7200rpm hard drives with a mean time between failure (MTBF) of 2 million hours. They are supported by a five-year limited warranty.

The new drives will be available in 6Gbps Serial ATA and 6Gbps Serial Attached SCSI interfaces and they are based on Hitachi's fifth-generation five-platter design, which according to Hitachi, is a technology that has an annualised failure rate (ANR) of 0.40 per cent over the last three years. In a press release, Brendan Collins, vice-president of product marketing at Hitachi GST said that "Raising our MTBF to 2 million hours on our new Ultrastar 7K3000 family reinforces this quality commitment. Our new Ultrastar drives will continue to play an important and growing role in data centres that require 24x7 availability for cloud storage, massive scale out (MSO) data farms, data warehousing, disk-to-disk backup, RAID arrays and more."

The energy requirement of the Ultrastar 7K3000 is claimed to be reduced compared to the previous generation of drives -- Ultrastar A7K2000 -- with the new drives boasting a 32 per cent power reduction when it comes to Watts per gigabyte.

With a dense 3TB capacity, up to 1.8PB (petabytes) of storage can be stacked in a typical 19in storage rack. The Ultrastar 7K3000 family of drives will also be available in 2TB offerings. The SATA interface drives are available now, while the SAS interface drives will be available in mid-2011.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.

Microsoft Office 365/Dell XPS 15 2-in-1

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

Brother PT-P750W

It’s useful for office tasks as well as pragmatic labelling of equipment and storage – just don’t get too excited and label everything in sight!

The Brother MFC-L8900CDW is an absolute stand out. I struggle to fault it.

MSI GT75 TITAN

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.
