The hard drive market has become a lot less sexy in the past few years thanks to SSDs. What we used to consider "fast" for a hard drive is relatively slow compared to even the cheapest of today's solid state drives. But there are two areas where hard drives still rule the roost, and that's in terms of overall capacity and cost per gigabyte. Right now you can buy a 4TB hard drive for the same cost as a 256GB SSD, so the two are in separate universes in that regard. We love SSDs and think just about everyone should run their OS on one, but most aren't large enough to hold all user data over a long... Read more...
In the data center, every little bit that saves on cooling or power consumption helps, and to that end Western Digital’s HGST brand is shipping a new hard drive that’s designed for higher-capacity storage, higher storage density, lower power consumption, and lower cooling requirements. The HGST 6TB Ultrastar He6 features the company’s 7Stac disk design, claiming 50% higher capacity in a standard 3.5-inch form factor over competitive 5-platter, 4TB drives. As we first wrote about last year, though, the premier feature of the new HGST platform is that it’s filled with helium... Read more...
HGST (formerly Hitachi Global Storage Technologies and now a wholly owned subsidiary of Western Digital) claims that its latest mobile hard drive, the Travelstar 5K1500, offers the--and we quote--“highest storage density of any hard disk drive today”. Those are strong words, but HGST may have something there. They crammed 1.5TB into a 2.5-inch, 9.5mm chassis that houses three platters. The drives also feature 32MB cache and a 6Gbps SATA interface with 5400 RPM speed. At idle, the Travelstar 5K1500 consumes just 0.5W of power and emits 2.5 bels, making it both power efficient and very... Read more...
When it comes to hard drives, performance is important but capacity is king. Western Digital is keeping pace with growing storage trends--including several of its own lines of products--by unveiling new 4TB versions of its WD Black desktop hard drives. The 3.5-inch drives offer 7200 RPM speed, 64MB cache, and SATA 6Gbps interfaces in addition to a handful of features designed to enhance accuracy and promote longevity. These include dual actuators that use two heads for more accurate positioning over data tracks as well as dual processors which are designed to enable significant performance boosts.... Read more...
When considering a new storage solution, most users try to find the right balance between speed and capacity. SSDs are super fast, no doubt about it, but an HDD spinning at 7200RPM or 10,000RPM will still offer solid performance, and you have access to dramatically more storage capacity for a far lower cost per GB compared to an SSD. Western Digital’s 4TB WD RE SATA drive certainly satisfies the need for capacity. And at a 7200RPM spindle speed with a SATA 6Gbps interface,64MB of cache, and up to 171MBps sustained transfer rates, the performance balance is there as well. In the enterprise,... Read more...

When it comes to adding a performance-enhancing upgrade to your system, a good SSD can’t be beat, but storage capacity is an ever-growing need as well. There was a time when a 1TB drive seemed grossly (deliciously?) excessive for the average user, but these days anything less than 500GB seems woefully undersized. Even casual users who play a few games, shoot a little video here and there, and maintain a modest music library need lots of storage. HDDs continue to increase in capacity yet remain reasonably priced in light of solid state offerings, to the point that you can have yourself a multiple-terabyte... Read more...
