Western Digital My Book VelociRaptor Duo Review: An Expensive Drive That Makes Good Use Of Thunderbolt

Featured image

Short version: Western Digital finally has released a new Thunderbolt external hard drive to justify the existence of the Thunderbolt port on your laptop. The My Book VelociRaptor Duo is a desktop external hard drive, which uses two 3.5-inch 1 TB VelociRaptor hard drives. These disks spin at 10,000 RPM and are a good compromise between speed and storage inside a desktop computer. Yet, using them in an external enclosure comes with a major drawback: a hefty price of $ 899.

Features:

  • Two 1 TB 10,000 RPM WD VelociRaptor drives
  • Two Thunderbolt ports for daisy-chaining
  • A Thunderbolt cable in the box — a $ 50 value
  • Drives can be replaced
  • RAID 0 or RAID 1 options to have a 2 TB drive (RAID 0) or two 1 TB drives always in sync (RAID 1)
  • Western Digital Product Page

Pros:

  • It’s fast
  • Daisy-chaining with Thunderbolt
  • You can replace a faulty drive

Cons:

  • MSRP: $ 899
  • Noisier than a MacBook Pro 13″
  • No USB3

Long version:

Before diving into some read/write tests, let’s talk about the external features of the VelociRaptor Duo. It is a heavy and bulky desktop hard drive that will sit on your desk in a corner and never move again.

At the same time, due to its speed and limited capacity compared to some desktop external hard drives — you can easily get a slower but comparably sized 6 TB drive for the same price — you will have to find a special use for it aside from storing backups of your computer. An entry-level NAS is another alternative that could be considered at that price.

For example, it would be a good addition to a current-generation MacBook Air limited by its 128 GB or 256 GB SSD. But SSD prices will certainly drop in the coming years.

The exterior of the VelociRaptor Duo is made entirely of plastic. It looks fine when sitting on your desk, but feels cheap when you are moving the drive around. A discreet LED indicates that the device is plugged correctly. The drive is also noisier than the MacBook Pro used to write this review, even when not reading or copying files.

It gets warm, but that’s not very important for a desktop external drive. You can change the hard drives quite easily without using a screwdriver. Even though VelociRaptor drives are standard 3.5-inch SATA drives, there is a sticker that says “Only use VelociRaptor drives.” It remains to be seen if it is a serious claim as for the European patent-protected Nespresso coffee machine or only marketing advice. Finally, a Thunderbolt cable is in the box, a $ 50 value.

Daisy-chaining multiple Thunderbolt devices is a convenient feature when using a laptop. For example, the VelociRaptor Duo is currently plugged to a MacBook Pro and a display is plugged to the VelociRaptor using a DVI to Mini DisplayPort adapter. Only one port is necessary on the laptop to use those two devices.

When it comes to performances, the VelociRaptor duo is a nice surprise. In Raid 0, we could measure 352.3 MB/s and 374.1 MB/s respectively for writing and reading large files. Yet, dealing with a lot of small files was much slower with 13.2 MB/s for random writing. That is the disadvantage of mechanical hard drives, but the VelociRaptor Duo appeared faster than the Buffalo MiniStation Thunderbolt. Clearly, the bottleneck is not the connectivity but the drive.

In real-world use, copying a folder from the MacBook Pro to the VelociRaptor Duo would not be relevant because of the 5,400 RPM hard drive found in that Mac. That is why we copied a 69 GB folder containing small and big files already on the VelociRaptor Duo. It took 13’02″, at an approximate speed of 89 MB/s. The same test would have been many times slower using a USB2 drive.

The VelociRaptor Duo is a particular drive filling a particular need for those that feel cramped using a small SSD as their main drive. It is expensive but makes good use of the Thunderbolt interface. Yet, it is very hard to recommend the drive because of the price. As SSD capacities will increase a lot in future laptops, a cheaper desktop external drive with Thunderbolt might be good enough. The rest of the money could be saved to buy your next laptop with a bigger SSD.

What Makes A City A City? New Visual System Identifies City Characteristics

Screen Shot 2012-08-18 at 7.39.06 PM

If you’ve been to cities and you’ve had enough, have you been to Paris, France? Paris is defined by a few magical characteristics – the street signs, the architecture, the street features – and a new system at Carnegie Mellon identifies cities based on their special traits.

The project describes a fairly complex algorithm that is able to find aspects from Google Street view.

Given a large repository of geotagged imagery, we seek to automatically find visual elements, e.g. windows, balconies, and street signs, that are most distinctive for a certain geo-spatial area, for example the city of Paris. This is a tremendously difficult task as the visual features distinguishing architectural elements of different places can be very subtle. In addition, we face a hard search problem: given all possible patches in all images, which of them are both frequently occurring and geographically informative? To address these issues, we propose to use a discriminative clustering approach able to take into account the weak geographic supervision. We show that geographically representative image elements can be discovered automatically from Google Street View imagery in a discriminative manner.

The system currently works in multiple city using large samples of images from cities around the world. Using these, the system can identify where a random photo was taken with some degree of accuracy. Interestingly, the system can also be used on everyday objects, including “discovering stylistic elements in other weakly supervised settings, e.g. “What makes an Apple product?’”

iOS Soars Ahead of Android Development As Apple Quietly Makes Move Into The Enterprise Market

ipadbiz

The Apple iOS is surging ahead of the Google Android platform for enterprise development, according to survey results from Appcelerator, the mobile platform development company.

In the largest survey of its kind, Appcelerator developers were asked what operating system is best positioned to win the enterprise market. Developers said iOS over Android by a 53% to 38% margin. Last year, in its second quarter survey, the two companies were in a dead heat for the enterprise market, tied at 44%.

In a surprise of sorts, Windows showed some life as 33% said they would be interested in developing apps on the Windows 8 tablet.

Each quarter, in conjunction with IDC Research, Appcelerator surveys its community of 340,000 developers. It is the largest survey of mobile developers. This quarter, more than 3,600 developers participated in the survey.

Apple’s dramatic push ahead is in part attributed to developers perception about Android. When asked what interests them, developers said the size of the market and the price point of the devices.

“Android s a consumer centric app in the eyes of developers,” said Appcelerator’s Director of Enterprise Strategy, Michael King.

Apple has also put more emphasis on supporting the enterprise through better security. They have worked closely with mobile device management companies such as MobileIron, SAP Afaria and Symantec’s Nukona.

On its Web site, Apple has successfully marketed its iOS products. For example, it markets the ways it is used; the companies that have adopted it; the apps and its security features. It beautifully shows the iPad and the innovative ways it can be used.  Its resources page helps people understand how to use, integrate, and support iPad in business environments.

In addition, Apple now has an enterprise associate in every Apple store.

Also reflected in the survey results, is a trend from consumer app development to enterprise apps. Two-thirds of those surveyed are building apps for their company or a business customer.

Enterprise managers are recovering from the bring your own device (BYOD) era. They are now learning how to manage devices and how to use them to innovate.

The interest in Windows is arguably as interesting as Apple’s gains. Could this be the new race between Apple and Microsoft?
