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.

Readers of PC Perspective have noticed that in the last couple of years a very familiar name has been asserting itself again in the world of gaming peripherals. Logitech, once the leader and creator of the gaming-specific market with devices like the G15 keyboard, found itself in a rut and was being closed in on by competitors such as Razer, Corsair and SteelSeries. The Logitech G brand was born and a renewed focus on this growing and enthusiastic market took place. We have reviewed several of the company’s new products including the G933/633 gaming headsets, G402 mouse that included an accelerometer and the G29 racing wheel.
Today Logitech is announcing the Logitech G Pro Gaming Mouse. As the name would imply, this mouse is targeted at gamers that fancy themselves as professionals, or aspiring to be so. As a result, I imagine that many “normie” PC gamers will find the design, features and pricing to be attractive enough to put next to the keyboard on their desk. This is a wired-only mouse.
The design of the Pro Gaming Mouse is very similar to that of the Logitech G100s, a long running and very popular mouse with the professional community. It falls a bit on the small side but Logitech claims that the “small and nimble profile allows gamers of many different game types to play as precisely as possible.” It’s incredibly light as well – measuring in at just 83g!
This mouse has 6 programmable buttons, much less than some of the more extreme “gaming” mice on the market, all of which can be controlled through the Logitech Gaming Software platform. The on-board memory on the Pro allows gamers to configure the mouse on their own system and take those settings with them to competition or friends’ PCs without the need to re-install software.
RGB lights are of course included with the Pro mouse and I like the idea of the wrap around the sides and back of the mouse to add some flair to the design.
Logitech is using the PMW3366 sensor in the Pro Gaming Mouse, the same used in the G502, G900 and others. Though mouse sensors might be overlooked for their importance in a gaming, the PMW3366 optical sensor is known to deliver accurate translations from 200-12,000 DPI with no acceleration or smoothing integrated that might hinder the input from the gamer.
The buttons on the Logitech G Pro use a torsion spring system rated at 20 million clicks (!!) which works out to 25 kilometers of button travel for the life of the mouse. The spring system used is designed to minimize effort and distance required for button actuation.
All aspects of the mouse were built with gamers in mind and with Logitech’s in-house professional gamers at the design table. Everything from the plastic feel, size, weight, etc. The scroll wheel is optimized for gamer’s use, not productivity, while the braided cable prevents snags. And the best part? The Logitech G Pro Gaming Mouse is set to have an MSRP of just $69.
The full press release is after the break and we are due to have a Logitech G Pro Gaming Mouse in our hands later today. We will follow up with thoughts and impressions soon!

It's been too long since we took a look at enterprise SSDs here at PC Perspective, so it's high time we get back to it! The delay has stemmed from some low-level re-engineering of our test suite to unlock some really cool QoS and Latency Percentile possibilities involving PACED workloads. We've also done a lot of work to distill hundreds of hours of test results into fewer yet more meaningful charts. More on that as we get into the article. For now, let's focus on today's test subject:
Behold the Micron 9100 MAX Series. Inside that unassuming 2.5" U.2 enclosure sits 4TB of flash and over 4GB of DRAM. It's capable of 3 GB/s reads, 2 GB/s writes, and 750,000 IOPS. All from inside that little silver box! There's not a lot more to say here because nobody is going to read much past that 3/4 MILLION IOPS figure I just slipped, so I'll just get into the rest of the article now :).
The 9100's come in two flavors and form factors. The MAX series (1.2TB and 2.4TB in the above list) come with very high levels of performance and endurance, while the PRO series comes with lower overprovisioning, enabling higher capacity points for a given flash loadout (800GB, 1.6TB, 3.2TB). Those five different capacity / performance points are available in both PCIe (HHHL) and U.2 (2.5") form factors, making for 10 total available SKUs. All products are PCIe 3.0 x4, using NVMe as their protocol. They should all be bootable on systems capable of UEFI/NVMe BIOS enumeration.
Idle power consumption is a respectable 7W, while active consumption is selectable in 20W, 25W, and 'unlimited' increments. While >25W operation technically exceeds the PCIe specification for non-GPU devices, we know that the physical slot is capable of 75W for GPUs, so why can't SSDs have some more fun too! That said, even in unlimited mode, the 9100's should still stick relatively close to 25W and in our testing did not exceed 29W at any workload. Detailed power testing is coming to future enterprise articles, but for now, the extent will be what was measured and noted in this paragraph.
Our 9100 MAX samples came only in anti-static bags, so no fancy packaging to show here. Enterprise parts typically come in white/brown boxes with little flair.
Introduction, Specifications and Packaging
Last week, Samsung flew myself and a few of my fellow peers in the storage review community out to Seoul, Korea. The event was the 2012 Samsung SSD Global Summit:
At this event, Samsung officially announced their new 840 Pro, which we were able to obtain early under NDA and therefore publish in concert with the announcement. The 840 Pro was largely an incremental inprovement over their 830 Series. Newer, faster flash coupled with a higher clocked controller did well to improve on an already excellent product.
As the event closed, we were presented with the second model of the lineup - the 840. This model, sans the 'Pro' moniker, is meant more for general consumer usage. The first mass marketed SSD to use Triple Level Cell (TLC) flash, it sacrifices some write speed and long-term reliability in favor of what should become considerably lower cost/GB as production ramps up to full capacity. TLC flash is the next step beyond MLC, which is in turn a step after SLC. Here's a graphic to demonstrate:

Allyn wasn't the only one blown away by the performance and efficiency increase of the new Samsung 840 Pro 512GB SSD, anyone who had a chance to review this drive saw incredible performance. It is not yet available for purchase but you can expect to see the 256G at $270 and this 512GB at around $600 when they do become available. Inside the 3-core eight channel MDX controller is paired with eight 64GB modules of Samsung’s new 21nm MLC DDR-2 toggle mode NAND, which give this drive its incredible speed. SSD Reviews came to the same conclusion that Al did, we need a new interface as SATA 6Gb/s is already being saturated by high end SSDs.
"Our report on the Samsung 840 Pro SSD begins post take off from Pearson Int’l Airport in Toronto and on route to Seoul, South Korea. Having had this SSD in our hands for some time, even the enormity of the Samsung 840 family release celebration cannot overshadow the performance of what just might be the hottest solid state drive to hit the streets to date. How does just under an extra hour laptop life and 100,000 IOPS grab you to start?"

Introduction, Specifications and Packaging
Samsung has been at this SSD thing for quite some time now. The first SSD I bought was in fact a Samsung unit meant for an ultraportable laptop. Getting it into my desktop was a hack and a half, involving a ZIF to IDE adapter, which then passed through yet another adapter to convert to SATA. The drive was wicked fast at the time, and while it handily slaughtered my RAID-0 pair of 74GB VelociRaptors in random reads, any writes caused serious stuttering of the drive, and therefore the entire OS. I was clearly using the drive outside of its intended use, but hey, I was an early adopter.
Several SSDs later came the Intel X25-M. It was a great drive, but in its earliest form was not without fault. Luckily, these kinks were worked out industry-wide, and everyone quickly accelerated their firmware optimizations as to better handle random writes. Samsung took a few generations to get this under control. The first to truly get over this hump was the 830 Series, which launched earlier this year. It utilized a triple core Arm 9 CPU which was able to effectively brute force heavy random write workloads. It also significantly increased the speed and nimbleness of the 830 across the board, which combined with Samsung's excellent reliability record, quickly made it my most recommended series as of late.
...and now we have the 840 Series, which launched today. Well, technically it launched yesterday if you're reading from the USA. Here in Korea the launch started at 10 AM and spanned a day of product press briefings leading to the product NDA expiration at 8 PM Korea time. This review will focus on the 512GB capacity of the 840 Pro model. We will follow on with the 840 (non-pro) at a later date:

Good morning from Seoul, Korea!
I'm here at the Samsung Global SSD Summit, where Samsung has officially launched their 840 Series of SSDs. This new controller features many advancements which enable it to climb past 100,000 IOPS in random reads (!!!). Samsung also claims peaks of 90,000 IOPS in random writes. These are seriously high numbers for any SATA SSD, and we will be publishing our full review of the 840 Pro once the NDA lifts later this evening (tomorrow morning for everyone back in the states).
Unfortunately there is nothing more I can disclose at this time, but stay tuned for more info! While all of you are sleeping tonight, I will be attending several briefings covering the 840, and those juicy tidbits will all be filtered into our review, so don't miss this one!
