Introduction and Internals
We've seen USB 3.0 in devices for a few years now, but it has only more recently started taking off since controllers, drivers, and Operating Systems have incorporated support for the USB Attached SCSI Protocol. UASP takes care of one of the big disadvantages seen when linking high speed storage devices. USB adds a relatively long and multi-step path for each and every transaction, and the initial spec did not allow for any sort of parallel queuing. The 'Bulk-Only Transport' method was actually carried forward all the way from USB 1.0, and it simply didn't scale well for very low latency devices. The end result was that a USB 3.0 connected SSD performed at a fraction of its capability. UASP fixes that by effectively layering the SCSI protocol over the USB 3.0 link. Perhaps its biggest contributor to the speed boost is SCSI's ability to queue commands. We saw big speed improvements with the Corsair Flash Voyager GTX and other newer UASP enabled flash drives, but it's time we look at some ways to link external SATA devices using this faster protocol. Our first piece will focus on a product from Inateck - their FE2005 2.5" SATA enclosure:
This is a very simple enclosure, with a sliding design and a flip open door at the front.

James Clifford started his career at Unisys Corporation, working his way up to VP & GM of Orange County Operations during over 20 years at that company, essentially handling their global sourcing and foundry needs. From there he moved to Qualcomm and again spent quite a bit of time, almost 18 years, serving in a variety of leadership roles and ending his time there as the Senior VP & GM of Operations. He then headed to RF Micro Devices, Inc for a brief time before joining AMD today in the role of Senior VP of Global Operations and reporting directly to Dr. Lisa Su according to the story at DigiTimes. This is an exciting move for AMD, hopefully his significant experience in the semiconductor industry will help move AMD forward over the coming years and help them regain their share of the marketplace.
"AMD has announced James Clifford has joined the company as senior vice president of Global Operations, reporting to president and CEO Lisa Su. Clifford will be responsible for overseeing all aspects of AMD's end-to-end manufacturing and supply chain strategy."

Hot on the heels of Fedora's release last week comes a Beta release of Red Hat Enterprise Linux. The new release comes with updates to user authentication via LDAP, Kerberos and FreeOTP as well as Security Content Automation Protocol Security Guides which are standards intended to make compliance and security testing easier. OpenLMI is a standardized remote API for configuring Linux severs and will be very welcome for those who have to manage servers remotely and may be one of the most heavily tested of the new features on this OS. Lastly, The Register notes that this version brings little-endian support when running on Power8 hardware which will make porting applications far less of a nightmare than it currently is.
"RED HAT HAS ANNOUNCED the availability of Red Hat Enterprise Linux (RHEL) 7.1 Beta with enhancements to improve ease of use, manageability and performance, as well as support for IBM Power8 little endian architecture."

Are you still hunting for that perfect gift for the hardware and technology fan in your life? Or maybe you are looking for recommendations to give to your friends and family about what to buy for YOU? Or maybe you just want something new and cool to play with over the break? Welcome to PC Perspective's 10 Days of Christmas where we will suggest a new item each day for you to consider. Enjoy!
Getting media from your PC to your TV is still a feat that can often take complicated software and dedicated hardware. There are several methods for getting around this headache including things like the Amazon FireStick, Intel's Wireless Display technology and Miracast. But perhaps the most interesting, and one of the least expensive, is the Google Chromecast.
Chromecast is a small thumb-stick sized device that plugs into an HDMI port on your TV and then connects to your wireless network. From there you can connect to the Chromecast with your desktop, laptop or mobile device that uses Chrome as the browser. Essentially, anything that can you watch or read or stream in Chrome can be send wirelessly to your TV. In addition, for Android smartphone and tablet users, a growing number applications support streaming to the Chromecast directly including Netflix, YouTube, HBO Go, Hulu Plus, Pandora, ESPN, MLB.TV, Google Play Movies and Music, Plex, MLS, crackle, Vevo, Rdio.
The only annoyance in setup is that the Chromecast requires a USB connection for power - but most TVs today have the necessary USB port so you don't have to use an AC adapter.
But damn, for only $29, this is a neat gadget worth giving a try!
If you are having trouble picking out a gift for a loved one, consider buying an Amazon.com gift card! Amazon has basically every product on the planet for your gift recipient to order and purchasing gift cards through these links directly sponsors and supports PC Perspective! And hey, if you were to buy gift cards for yourself to do your own Amazon-based Christmas shopping...that wouldn't exactly be a bad thing for us either! ;)
