Introduction, Specifications and Packaging
Micron paper launched their 5100 Series Enterprise SATA SSD lineup early last month. The new line promised many sought after features for such a part, namely high performance, high-performance consistency, high capacities, and relatively low cost/GB (thanks to IMFT 3D NAND which is now well into volume production since launching nearly two years ago). The highs and lows I just rattled off are not only good for enterprise, they are good for general consumers as well. Enterprises deal in large SSD orders, which translates to increased production and ultimately a reduction in the production cost of the raw NAND that also goes into client SSDs and other storage devices.
The 5100 Series comes in three tiers and multiple capacities per tier (with even more launching over the next few months). Micron sampled us a 2TB 'ECO' model and a 1TB 'MAX'. The former is optimized more for read intensive workloads, while the latter is designed to take a continuous random write beating.
I'll be trying out some new QoS tests in this review, with plans to expand out with comparisons in future pieces. This review will stand as a detailed performance verification of these two parts - something we are uniquely equipped to accomplish.
New Products for 2017
PC Perspective was invited to Austin, TX on May 11 and 12 to participate in ARM’s yearly tech day. Also invited were a handful of editors and analysts that cover the PC and mobile markets. Those folks were all pretty smart, so it is confusing as to why they invited me. Perhaps word of my unique talent of screenshoting PDFs into near-unreadable JPGs preceded me? Regardless of the reason, I was treated to two full days of in-depth discussion of the latest generation of CPU and GPU cores, 10nm test chips, and information on new licensing options.
Today ARM is announcing their next CPU core with the introduction of the Cortex-A73. They are also unwrapping the latest Mali-G71 graphics technology. Other technologies such as the CCI-550 interconnect are also revealed. It is a busy and important day for ARM, especially in light of Intel seemingly abandoning the sub-milliwatt mobile market.
ARM previously announced the Cortex-A72 in February, 2015. Since that time it has been seen in most flagship mobile devices in late 2015 and throughout 2016. The market continues to evolve, and as such the workloads and form factors have pushed ARM to continue to develop and improve their CPU technology.
The Sofia Antipolis, France design group is behind the new A73. The previous several core architectures had been developed by the Cambridge group. As such, the new design differs quite dramatically from the previous A72. I was actually somewhat taken aback by the differences in the design philosophy of the two groups and the changes between the A72 and A73, but the generational jumps we have seen in the past make a bit more sense to me.
The marketplace is constantly changing when it comes to workloads and form factors. More and more complex applications are being ported to mobile devices, including hot technologies like AR and VR. Other technologies include 3D/360 degree video, greater than 20 MP cameras, and 4K/8K displays and their video playback formats. Form factors on the other hand have continued to decrease in size, especially in overall height. We have relatively large screens on most premium devices, but the designers have continued to make these phones thinner and thinner throughout the years. This has put a lot of pressure on ARM and their partners to increase performance while keeping TDPs in check, and even reducing them so they more adequately fit in the TDP envelope of these extremely thin devices.

With CES right around the corner, we’re about to be buried in a deluge of announcements from consumer electronics vendors. Since I was not able to get out to CES in person this year, Qualcomm offered to give me a sneak peek at their new “Streamboost” technology they’ve just announced and will be showing at CES. I got to spend some time on the phone with Ciera Jammal, their PR rep and Michael Cubbage, Director of Business Development in their networking unit. For those of you that may not recognize Michael’s name, he was one of the co-founders of Bigfoot Networks that brought us their “Killer Gaming” line of Ethernet and wireless products. Acquired by Qualcomm in the fall of 2011, the merged Bigfoot and Qualcomm teams have now released “Streamboost”.
So, what is Streamboost you ask? Simply put, it’s an innovative Quality of Service engine that’s much, much more than what’s available for consumer QoS today. QoS on most current consumer products only looks at what ports traffic is flowing across and prioritizes the traffic based on a simple list of what ports should be given priority at the expense of traffic on lower priority ports. There’s no analysis of what the actual traffic is and in cases where different types of traffic flows over the same port (port 80 for example) it doesn’t offer any benefit at all. The Streamboost engine on the other hand, will actually inspect the packets in real time, determining not only what port the traffic is using, but what the traffic actually is. So for example, Streamboost will be able actually be able to tell that one stream is 1080p YouTube video while another is Standard Definition Netflix traffic, even though they are both on port 80, and give both streams the bandwidth they need.
Once the engine determines what type of data is moving through the connection, it will give that connection the bandwidth it needs to run optimally, but no more. The “no more” piece is important because it frees up bandwidth for other applications and connections. If there is not enough bandwidth available for the “Optimal” setting, it will then drop back and make every effort to give the connection what’s been determined to be the “Minimum acceptable” bandwidth needed for that type of traffic.
How does Streamboost know what bandwidth is Optimal and what bandwidth is Minimum? Well, Qualcomm has studied various types of traffic ranging from YouTube to Netflix to Call of Duty to torrents, and they’ve come up with the Optimal and Minimum bandwidth values for all types of traffic. This data will be included in a “Detection and Policy Table” on the router that the Streamboost engine will reference. My first thoughts when I heard this was that it sounded great, but what happens when that table gets out of date? Qualcomm has thought of that as well and Streamboost includes an opt-in, cloud based service that will keep your router’s table up to date. Not only that, but if the router encounters a new type of traffic not in its table, it will capture a few packets and send them up to the cloud (anonymized of course) to be analyzed and added to future table updates. Your router should actually perform better as it’s table is updated and will be better after a year than it was on Day 1. However, if you’re not interested in being part of the “Opt In crowd”, the engine can also be manually updated at any time.
The UI looks great and will let you drill down into your bandwidth use either by application or device. Speaking of devices, Streamboost can detect the various types of devices on your network and lets you prioritize based on those criteria as well.
D-Link and Alienware are the first two partners onboard with Streamboost and will be showing routers with the technology at CES as well as releasing them this spring. All in all, after speaking to Qualcomm, I think I’m going to hold off my planned router upgrade until I can get my hands on a new router with Streamboost built in.
