Well that was an alphabet soup of a title.
Samsung has just announced a new line of SSDs, based on three bit per cell (TLC) memory, for enterprise customers. The Samsung 845DC EVO is rated at 530MB/s reads with 87,000 IOPS. The company will also cover up to 600TB of writes under its warranty (no mention of length in years, though). The drive will be available "later this month" in 240GB, 480GB, and 960GB models. Samsung did not mention price in their press release, but Anandtech claims the 240GB will be $250, the 480GB will be $490, and the 960GB will be $969.
Samsung's SSDs will give you some TLC???
This is basically $1/GB scaling, plus $10. I must admit, this is getting pricy. In the consumer space, we have recently seen 512GB for $199. That said, SSDs are not known for sticking to their MSRP. Also, these are enterprise-rated drives. Being TLC-based, I wonder how much (if any) SLC-style write cache was included, as per the consumer 840 EVO.
Lastly, Samsung claims that these drives use around 4W under load. This is much lower than hard drives but a little high for SSDs, according to benchmarks that I have seen. That said, there are a few ways to parse that (for example, if they mean that its peak is typically 4W, which would be pretty good for a 960GB drive).
The Samsung 845DC EVO will be available later this month for a little over $1/GB.

ADATA has been showing off some upcoming products at Computex, and it's all about DRAM.
We'll begin with an upcoming line of PCIe Enterprise/Server SSDs powered by the SandForce SF3700-series controller. We've been waiting for products with the SF3700 controller since January, when ADATA showed a prototype board at CES, and ADATA is now showcasing the controller in the "SR1020" series drives.
The first is a 2TB 2.5" drive, but the interface was not announced (and the sample on the floor appeared to be an empty shell). The listed specs are performance up to 1800MB/s and 150K IOPS, with the drive powered by the SF-3739 controller. Support for both AHCI and NVMe is also listed, along with the usual TRIM, NCQ, and SMART support.
Another 2TB SSD was shown with exactly the same specs as the 2.5" version, but this one is built on the M.2 spec. The drive will connect via 4 lanes of Gen 2 PCI Express. Both drives in ADATA's SR1020 PCIe SSD lineup will be available in capacities from 240GB - 2TB, and retail pricing and availability is forthcoming.
Continuing the DRAM theme, ADATA also showed new DDR4 modules in commodity and enthusiast flavors. Both of the registered DIMMs on display (an ultra-low profile DIMM was also shown) had standard DDR4 specs of 2133MHz at 1.2V, but ADATA also showed some performance DDR4 at their booth.

No pricing or availability just yet on these products.

SATA Express is an interface to either connect a hard drive to PCIe lanes, or up to two drives via SATA. Obviously, PCIe bandwidth over a cable connection is the real draw. To use the full speed, however, the drive needs to be able to communicate over PCIe. Currently, the standard uses two PCI Express 2.0 lanes (1 GB/s).
Now that Z97 and H97 have launched, WD is set to show off the technology at Computex. The above image is apparently of a dual-drive product, containing 4TB of rotating media and 128GB of SSD memory. I am immediately reminded of the Western Digital Black2 dual drive which Allyn reviewed last November. That product crammed a 120GB SSD into a 2.5" 1TB HDD, which appeared to the system as two separate drives. The drive has "Technology Demonstration" written in red font right on it, but it could be a good representation of what the company is thinking about.
WD also asserts that their prototype uses standard AHCI drivers, for OS compatibility.
If you want to see this product in action, then -- well -- you kind-of need to be at Computex. At some point, you might be able to see it in your own PC. When? How much? No pricing and availability, again, because it is a tech demo.
Introduction, Specifications and Packaging
Intel has a nasty habit of releasing disruptive technology, especially in the area of computer storage. Among the first of those releases was the X25-M, which was groundbreaking to say the least. At a time where most other SATA SSDs were just stopgap attempts to graft flash memory to a different interface, Intel's SATA SSD was really the first true performer.
With performance in the bag, Intel shifted their attention to reducing the cost of their products. The next few generations of the Intel line was coupled with leadership in die shrinks. This all came together in the form of SSD releases of increasingly reduced cost. Sure the enterprise parts retained a premium, but the consumer parts generally remained competitive.
Now Intel appears to have once again shifted their attention to performance, and we know it has been in the works for a while now. With the SATA bottleneck becoming increasingly apparent, big changes needed to me made. First, SATA, while fine for relatively high latency HDD's, was just never meant for SSD speeds. As SSD performance increased, the latencies involved with the interface overhead (translating memory-based addresses into ATA style commands) becomes more and more of a burden.
The solution is to not only transition to PCIe, but to do so using a completely new software and driver interface, called NVM Express. NVMe has been in the works for a while, and offers some incredible benefits in that it essentially brings the flash memory closer to the CPU. The protocol was engineered for the purpose of accessing flash memory as storage, and doing so as fast and with the least latency as possible. We hadn't seen any true NVMe products hit the market, until today, that is:
Behold the Intel SSD DC P3700!
Introduction, Specifications and Packaging
Back in July of last year, Micron announced production of 16nm flash memory. These were the same 128gbit dies as the previous gen parts, but 16nm means the dies are smaller, meaning more dies from a single wafer, ultimately translating to lower end user cost.
It takes a bit of time for those new flash die shrinks to trickle into mainstream products. Early yields from a given shrink tend to not have competitive endurance on initial production. As production continues, the process gets tweaked, resulting in greater and longer enduring yields.

The Flash Voyager GTX is Corsair's attempt to be an SSD over USB 3.0. Differentiating itself from a standard USB flash drive, the Voyager GTX includes TRIM support, S.M.A.R.T. monitoring, and interfaces with USB Attached SCSI. It also comes in two, SSD-sized capacities, 128GB ($119.99) and 256GB ($199.99). These drives are rated at 450MB/s read and 350MB/s write.
This pricing structure puts the Voyager GTX against the Samsung 840 Pro, which is an interesting comparison to make. Both drives are backed by a five (5) year warranty and, while the 840 Pro has higher read bandwidth, the write speeds are fairly comparable. IOPS and write durability is not listed for the Corsair Flash Voyager GTX but, even if they are marginally behind, this has the advantage of USB.
Benchmarking should be interesting for this. I would be curious if this could lead to portable OS installations and abrupt boosts to Steam library sizes, both with SSD-like speeds.
The Corsair Flash Voyager GTX USB 3.0 drives will be available in July. The 128GB version has an MSRP of $119.99, while the 256GB is listed at $199.99.

Today Corsair annouces the Voyager Air 2, a wireless hard drive with 1TB of storage which can connect to iOS and Android devices, as well as PCs and Macs.
The Voyager Air 2 is battery-powered and rechargeable (Corsair estimates 7-hour battery life from the high-capacity rechargeable lithium-ion battery), and the included software syncs with Dropbox and Google Drive and supports AirPlay streaming to an Apple TV. It supports 802.11b/g/n Wi-Fi connections for multiple users within a 90 foot range, and can stream 720p high-definition video to up to five devices at once.
And the Voyager Air 2 has quite a bit more functionality than just streaming content over Wi-Fi. It can serve as a wireless hub to share internet access via wireless passthrough, and it also functions as a USB 3.0 drive for fast data transfers when connected to a computer.
The Voyager Air 2 will be available this month with a suggested price of $179.99.
The N2310 is a budget dual-bay NAS from Thecus and an interesting product beyond the low cost for this category, boasting a number of features that help set it apart.
Apart from the primary role of a network attached storage (NAS) device - you know, storage - there are some interesting things a piece of hardware like the N2310 can do. This inexpensive NAS is actually a server, too, so beyond storing up to 8TB of data it’s powerful enough to replace a dedicated PC for certain tasks - the kind of tasks that some of us leave a PC running 24/7 to accomplish.
In this review we’ll take a look at some of the functionality that helps set the N2310 apart, as well as the kind of real-world performance you might expect to see.
It’s All About the Gigabytes
There are more reasons now than ever before for large storage options. Even though SSD’s are at their lowest prices ever most of us still need to supplement a fast boot drive with some traditional spinning disks. Just think about what accumulates in an average year on your PC… photos, music, videos, program backups and images, you name it. All those GB’s have to go somewhere, and there are obviously internal and external hard drives to share the load. However, regardless of the local storage option you might chose, it’s not always so convenient to actually access this stuff again. Clearly, the easier it is to access your files, the better - and not just from one device. So, having centralized storage is a great idea, right?
Between computers, tablets, and of course our phones, there are generally quite a few connected devices in the average technology-inclined home. And while every device mentioned can connect to the internet - and cloud storage has become very popular - there's still something to be said for local content management. Beyond the convenience of sharing sometimes massive amounts of data easily at home, another benefit of always-on storage is backup. Ideally, every computer in the home would be backed up locally as well as the cloud, and a great way to take care of the local side of backup is with a NAS. Setting one up is very easy these days, with a growing number of affordable options from various vendors.
Thecus makes an interesting case for a budget NAS with the N2310. For a comparison, Allyn recently looked at Western Digital’s My Cloud EX2 network drive, and this is a highly polished all-in-one solution is now selling for about $199 (without drives). The Thecus N2310 is less expensive at $149, and both offer two 3.5” drive bays. (The My Cloud is also offered pre-populated with drives providing up to 8TB of storage.) These “diskless” enclosures present a good opportunity to save some money up front, and whether you choose to run on two drives you happened to have around the house or office, or if you want to go out and grab a couple of Western Digital 4TB Red drives, they can accommodate your situation.
Let’s take a look at the Thecus N2310.

The Super Talent RAIDDrive II Plus is a rather interesting take on a PCIe SSD card, it's USB 3.0 connected 25nm MLC NAND storage is on one PCB with a SF-2281 to handle the traffic and on the second PCB is an LSI 2108 RAID on a Chip and 1GB of DDR2-800. That LSI RoC can support most RAID modes, giving you either higher performance or increased reliability all on a single PCIe SSD card. For testing purposes The SSD Review used RAID 0 and found that except in one certain scenario the card was outclassed by a single Intel 480 SSD. If you are not scared of a tough price of $4/GB on a 2TB device and need fast large block sequential reads and writes with no expectation of quick random reads nor writes this is a good choice. Otherwise you might want to consider other alternatives but the technology on this device is rather intriguing.
"The second type of PCIe add-in-card storage takes more of a brute force approach. These devices typically have off-the-shelf SATA/SAS controllers and connect via a PCIe bridge. Think of a HBA/RAID card connected to a SATA SSD, but on a single card. These designs have many advantages and disadvantages. While the cost and time-to-market can be low, they are inherently limited due to the architecture."
