Jim was not the only one who completed benchmarking Samsung's new 970 EVO Plus, The Tech Report also chewed on the new gum stick for a while. Whereas we had the 1TB model, it was the 500GB model which they reviewed and while many of the specifications are the same there are some slight differences worth investigating. Their custom RoboBench tests real performance and shows just how impressive this drives performance is. Not only is this drive faster than the previous generations, the price is also much more attractive as we are supposed to see this 500GB drive sell for $130 and the 1TB for $250; let's hope that is the case!
"Samsung's 900-series EVO drives have been mainstays since NVMe went mainstream. The company has released a newly refreshed version of the 970 EVO that's so good they gave it a "Plus" suffix. We take it apart to see if it's as good as it sounds."

Samsung today is launching a new member of its consumer-targeted family of NVMe SSDs, the Samsung 970 EVO Plus. Thanks to the upgrade from 64-layer to 96-layer V-NAND, this new drive promises significantly better write performance, a slight bump to overall responsiveness, and improved efficiency all in the same single-sided package at capacities up to 2TB.
This new drive, a mid-cycle refresh that keeps the well-regarded 970-series on the market, looks impressive on paper. But do those soaring advertised IOPS and insane write speeds hold up in reality? Check out our initial review of the Samsung 970 EVO Plus.

ServeTheHome got up close and personal with Optane DC Persistent Memory in an article posted yesterday, removing the heat spreaders and taking a look at (and several photos of) the components within.

"We are going to take a 128GB Intel Optane Persistent Memory DDR4 module, and open it up. Until now, Intel Optane DC Persistent Memory has mostly been photographed with its big black heat spreader. We ended up with a handful of modules not from Intel, nor a system provider, but a handful to use."
Among their notes we have this interesting find, as SK.Hynix is the provider of the module's DRAM, rather than Micron:
"On the other side of the module from the Optane controller is a DDR4 DRAM module, this one from SK.Hynix. Model number H5AN4G8NAFR-TFC. We are not sure why Intel would not use a Micron module here since Micron has been the manufacturing partner for 3D XPoint thus far."

Build and Upgrade Components
Spring is in the air! And while many traditionally use this season for cleaning out their homes, what could be the point of reclaiming all of that space besides filling it up again with new PC hardware and accessories? If you answered, "there is no point, other than what you just said," then you're absolutely right. Spring a great time to procrastinate about housework and build up a sweet new gaming PC (what else would you really want to use that tax return for?), so our staff has listed their favorite PC hardware right now, from build components to accessories, to make your life easier. (Let's make this season far more exciting than taking out the trash and filing taxes!)
While our venerable Hardware Leaderboard has been serving the PC community for many years, it's still worth listing some of our favorite PC hardware for builds at different price points here.
Processors - the heart of the system.
No doubt about it, AMD's Ryzen CPU launch has been the biggest news of the year so far for PC enthusiasts, and while the 6 and 4-core variants are right around the corner the 8-core R7 processors are still a great choice if you have the budget for a $300+ CPU. To that end, we really like the value proposition of the Ryzen R7 1700, which offers much of the performance of its more expensive siblings for a really compelling price, and can potentially be overclocked to match the higher-clocked members of the Ryzen lineup, though moving up to either the R7 1700X or R7 1800X will net you higher clocks (without increasing voltage and power draw) out of the box.
Really, any of these processors are going to provide a great overall PC experience with incredible multi-threaded performance for your dollar in many applications, and they can of course handle any game you throw at them - with optimizations already appearing to make them even better for gaming.
Don't forget about Intel, which has some really compelling options starting even at the very low end (Pentium G4560, when you can find one in stock near its ~$60 MSRP), thanks to their newest Kaby Lake CPUs. The high-end option from Intel's 7th-gen Core lineup is the Core i7-7700K (currently $345 on Amazon), which provides very fast gaming performance and plenty of power if you don't need as many cores as the R7 1700 (or Intel's high-end LGA-2011 parts). Core i5 processors provide a much more cost-effective way to power a gaming system, and an i5-7500 is nearly $150 less than the Core i7 while providing excellent performance if you don't need an unlocked multiplier or those additional threads.

As we are not going to see scanning tunnelling microscopes included in our home computers anytime soon this experiment is simply proof of the concept that data can be stored on a single atom. That does not make it any less interesting for those fascinated by atomic storage techniques. A single atom of holmium can be made to spin either up or down, signifying either a 0 or 1, and that spin state can be 'read' by measuring the vibration of a single iron atom located close by. The holmium atoms used for storage can be separated by a mere nanometer without interfering with the spin of its neighbours. The spin state only lasts a few hours but shows that this could someday be a viable storage technology. You can read more at nanotechweb, who also have links to the Nature article.
"Information has been stored in a single atom for the first time. The nascent binary memory was created by Andreas Heinrich at the Institute of Basic Science in South Korea and an international team."

Tagged: XPoint, Worm, storage, ssd, RocksDB, Optane, nand, flash, facebook
At their FMS 2016 Keynote, Facebook gave us some details on the various storage technologies that fuel their massive operation:
In the four corners above, they covered the full spectrum of storing bits. From NVMe to Lightning (huge racks of flash (JBOF)), to AVA (quad M.2 22110 NVMe SSDs), to the new kid on the block, WORM storage. WORM stands for Write Once Read Many, and as you might imagine, Facebook has lots of archival data that they would like to be able to read quickly, so this sort of storage fits the bill nicely. How do you pull off massive capacity in flash devices? QLC. Forget MLC or TLC, QLC stores four bits per cell, meaning there are 16 individual voltage states for each cell. This requires extremely precise writing techniques and reads must appropriately compensate for cell drift over time, and while this was a near impossibility with planar NAND, 3D NAND has more volume to store those electrons. This means one can trade the endurance gains of 3D NAND for higher bit density, ultimately enabling SSDs upwards of ~100TB in capacity. The catch is that they are rated at only ~150 write cycles. This is fine for archival storage requiring WORM workloads, and you still maintain NAND speeds when it comes to reading that data later on, meaning that decade old Facebook post will appear in your browser just as quickly as the one you posted ten minutes ago.
Next up was a look at some preliminary Intel Optane SSD results using RocksDB. Compared to a P3600, the prototype Optane part offers impressive gains in Facebook's real-world workload. Throughput jumped by 3x, and latency reduced to 1/10th of its previous value. These are impressive gains given this fairly heavy mixed workload.
More to follow from FMS 2016!

Microsemi's Flashtec NVMe SSD controllers are now in production, and as Computer Base reports (Google-translated version of the page available here) these controllers use twice as many PCIe lanes than current offerings with a x8 PCI-E 3.0 connection, and can support up to 20 TB of flash capacity.
Image credit: Computer Base
"The NVMe controller destined for the professional high-performance segment and work with PCIe 3.0 x8 or two x4 PCIe 3.0. The NVMe2032 has 32 memory channels (and) NVMe2016 (has) 16. When using 256-Gbit flash SSDs can be implemented with up to 20 terabytes of storage."
The 32-channel NVMe2032 boasts up to 1 million IOPS in 4K random read performance, and the controller supports DDR4 memory for faster cache performance. The announcement of the availability of these chips comes just before the start of Flash Memory Summit, which our own Allyn Malventano will be attending. Stay tuned for more flashy SSD news to come!

Thecus has announced their newest NAS with the N4810, an 4-bay design based on the existing N2810PRO 2-bay model. The N4810 offers up to 40 TB of hard drive storage support, and an Intel Celeron N3160 (quad-core) processor with 4GB of RAM, which can be expanded to 8GB.
Image credit: Thecus
"With the N4810 built on the hardware of its little brother, the N2810PRO, users are equipped with the same immersive multimedia experience. Delivering superb sharpness and colour contrasts in 4K resolution playback, accessed through the HDMI output or DisplayPort output, guaranteeing that the picture quality from movies is just as the director envisioned.
Connection to your digital sound system via a SPDIF output is available, providing crystal clear audio for music and movies. A new USB 3.0 Type-C port has been added to the three already equipped USB 3.0 ports. This Type-C connector is the size of a microUSB and has a reversible plug allowing cables to be conveniently plugged in either direction."
Image credit: Thecus
The NAS is geared toward the living room, with HDMI output along with DisplayPort, and display output up to UHD/4K. We took a look at the 2-bay N2560 NAS a couple of years ago, and on paper this new model offers a substantial upgrade as an entertainment/HTPC solution. Availability is set for this month.

Sony has developed a higher-capacity version of their Optical Disc Archive (ODA), which now allows up to 3.3 TB of archival storage with the promise of 100-year retention.

Of course the viability of such a system in the next century is unknown, and a working cartridge (which is similar to the multi-CD systems found in cars a few years ago) would be needed to access the data. The idea is certainly interesting considering the potential for failure with traditional hard drives, though hard drives are relatively inexpensive and offer more utility, unlike the write-once Sony ODA cartridges.

For those seeking pure read-only archival storage, the higher capacity of the second-generation Sony ODA at least brings it closer to parity with current hard drive storage.

Tagged: storage, ssd, solid-state drive, Samsung, PM1725, enterprise
The 950 Pro SSD is here, (and Allyn has the full review right here) and while it's the fastest consumer SSD out there, the latest enterprise SSD demo from Samsung is absolutely insane.
Image credit: Kit Guru
The PM1725 has a PCI Express 3.0 x8 interface, and a 2.5" version will also be available (though limited to PCI Express 3.0 x4). And with read speeds in excess of 6.2 GB/s the PM1725 sounds like a RAM disk. And if that wasn't enough the drive managed a million IOPS from a demo performance for this new SSD at Dell World in Austin, Texas.
Image credit: Tom's Hardware
Tom's Hardware had hands-on time with the card and was able to run a few benchmarks verifying the outlandish speeds from this SSD, with their 6.2+ GB/s result coming from a 128k QD32 sequential test, with the IOPS test run as a 4k random read.

I'm sure the price will be similarly out of this world and this of course isn't a consumer-oriented (or likely even bootable) option. For now the Samsung 950 Pro is the object of NVMe desire for many, and for $199.99 ($0.78/GB) for the 256 GB model and $349.99 ($0.68/GB) for the 512 GB model on Amazon.com the 950 Pro is pretty reasonable - even if they "only" offer up to 2.5 GB/s reads and 1.5 GB/s writes. I'd certainly take it!
