Introduction, Specifications and Packaging
Where are all the 2TB SSDs? It's a question we've been hearing since they started to go mainstream seven years ago. While we have seen a few come along on the enterprise side as far back as 2011, those were prohibitively large, expensive, and out of reach of most consumers. Part of the problem initially was one of packaging. Flash dies simply were not of sufficient data capacity (and could not be stacked in sufficient quantities) as to reach 2TB in a consumer friendly form factor. We have been getting close lately, with many consumer focused 2.5" SATA products reaching 1TB, but things stagnated there for a bit. Samsung launched their 850 EVO and Pro in capacities up to 1TB, with plenty of additional space inside the 2.5" housing, so it stood to reason that the packaging limit was no longer an issue, so why did they keep waiting?
The first answer is one of market demand. When SSDs were pushing $1/GB, the thought of a 2TB SSD was great right up to the point where you did the math and realized it would cost more than a typical enthusiast-grade PC. That was just a tough pill to swallow, and market projections showed it would take more work to produce and market the additional SKU than it would make back in profits.
The second answer is one of horsepower. No, this isn't so much a car analogy as it is simple physics. 1TB SSDs had previously been pushing the limits of controller capabilities of flash and RAM addressing, as well as handling Flash Translation Layer lookups as well as garbage collection and other duties. This means that doubling a given model SSD capacity is not as simple as doubling the amount of flash attached to the controller - that controller must be able to effectively handle twice the load.
With all of that said, it looks like we can finally stop asking for those 2TB consumer SSDs, because Samsung has decided to be the first to push into this space:
Today we will take a look at the freshly launched 2TB version of the Samsung 850 EVO and 850 Pro. We will put these through the same tests performed on the smaller capacity models. Our hope is to verify that the necessary changes Samsung made to the controller are sufficient to keep performance scaling or at least on-par with the 1TB and smaller models of the same product lines.
Introduction, Specifications, and Packaging
Lexar is Micron’s brand covering SD Cards, microSD Cards, USB flash drives, and card readers. Their card readers are known for being able to push high in the various speed grades, typically allowing transfers (for capable SD cards) much faster than what a typical built-in laptop or PC SD card reader is capable of. Today we will take a look at the Lexar ‘Professional Workflow’ line of flash memory connectivity options from Lexar.
This is essentially a four-bay hub device that can accept various card readers or other types of devices (a USB flash storage device as opposed to just a reader, for example). The available readers range from SD to CF to Professional Grade CFast cards capable of over 500 MB/sec.
We will be looking at the following items today:
- Professional Workflow HR2
- Four-bay Thunderbolt™ 2/USB 3.0 reader and storage drive hub
- Professional Workflow UR1
- Three-slot microSDHC™/microSDXC™ UHS-I USB 3.0 reader
- Professional Workflow SR1
- SDHC™/SDXC™ UHS-I USB 3.0 reader
- Professional Workflow CFR1
- CompactFlash® USB 3.0 reader
- Professional Workflow DD256
- 256GB USB 3.0 Storage Drive
Note that since we were sampled these items, Lexar has begun shipping a newer version of the SR1. The SR2 is a SDHC™/SDXC™ UHS-II USB 3.0 reader. Since we had no UHS-II SD cards available to test, this difference would not impact any of our testing speed results. There is also an HR1 model which has only USB 3.0 support and no Thunderbolt, coming in at a significantly lower cost when compared with the HR2 (more on that later).

Samsung's M.2 SM951 PCIe SSD was never originally intended to be sold on its own but thankfully the 128, 256 and 512GB models are showing up on Newegg and other sites and the speeds it can reach are very impressive. The Tech Report tested the 512GB model and saw it beat the Intel 750 Series in IOMeter at a queue depth of one, though the Intel SSD still shows off its prowess at higher queue depths. Their testing showed that the speed of the flash produces enough heat that the drive throttles itself so you should consider rigging an active cooling solution if you do pick up this drive. Check out their full review to see some very impressive numbers and boot times.
"Samsung's SM951 SSD squeezes a quad-lane PCIe Gen3 interface onto a diminutive M.2 form factor. It offers incredible performance under the right conditions, but it also struggles in some scenarios. Our in-depth review explains the drive's strengths, weaknesses, and unique enthusiast appeal."

One hub to rule them all!
Inateck sent along a small group of connectivity devices for us to evaluate. One such item was their HB7003 7 port USB 3.0 hub:
This is a fairly standard powered USB hub with one exception - high speed charging. Thanks to an included 36W power adapter and support for Battery Charging Specification 1.2, the HB7003 can charge devices at up to 1.5 Amps at 5 Volts. This is not to be confused with 'Quick Charging', which uses a newer specification and more unique hardware.
- L/W/H: 6.06" x 1.97" x 0.83"
- Ports: 7
- Speed: USB 3.0 5Gbps (backwards compatible with USB 2.0 and 1.1)
- Windows Vista / OSX 10.8.4 and newer supported without drivers
Densely packed brown box. Exactly how such a product should be packaged.
Power adapter (~6 foot cord), ~4.5 foot USB 3.0 cord, instruction manual, and the hub itself.
Some quick charging tests revealed that the HB7003 had no issue exceeding 1.0 Amp charging rates, but fell slightly short of a full 1.5A charge rate due to the output voltage falling a little below the full 5V. Some voltage droop is common with this sort of device, but it did have some effect. In one example, an iPad Air drew 1.3A (13% short of a full 1.5A). Not a bad charging rate considering, but if you are expecting a fast charge of something like an iPad, its dedicated 2.1A charger is obviously the better way to go.
Performance and Usability:
As you can see above, even though the port layout is on a horizontal plane, Inateck has spaced the ports enough that most devices should be able to sit side by side. Some wider devices may take up an extra port, but with seven to work with, the majority of users should have enough available ports even if one or two devices overlap an adjacent port. In the above configuration, we had no issue saturating the throughput to each connected device. I also stepped up to a Samsung USB T1 which also negotiated at the expected USB 3.0 speeds.
Pricing and Availability
- $34.99 (Amazon)
Inateck is selling it these direct from their Amazon store (link above).
- Clean design 7-port USB 3.0 hub.
- Port spacing sufficient for most devices without interference.
- 1.5A per port charging.
- Low cost.
- 'Wall wart' power adapter may block additional power strip outlets.
At just $35, the Inateck HB7003 is a good quality 7-port USB 3.0 hub. All ports can charge devices at up to 1.5A while connecting them to the host at data rates up to 5 Gbps. The only gripe I had was that the hub was a bit on the light weight side and as a result it easily slid around on the desk when the attached cords were disturbed, but some travelers might see light weight as a bonus. Overall this is a simple, no frills USB 3.0 hub that gets the job done nicely.
You love the dock!
Today we'll take a quick look at the Inateck FD2002 USB 3.0 to dual SATA dock:
This is a UASP capable dock that should provide near full SATA 6Gb/sec throughput to each of two connected SATA SSDs or HDDs. This particular dock has no RAID capability, but exchanges that for an offline cloning / duplication mode. While the FD2002 uses ASMedia silicon to perform these tasks, similar limitations are inherent in competing hardware fron JMicron, which comes with a similar toggle of either RAID or cloning capability. Regardless, Inateck made the logical choice with the FD2002, as hot swap docks are not the best choice for hardware RAID.
The pair of ASMedia chips moving data within the FD2002. The ASM1153E on the left couples the USB 3.0 link to the ASM1091R, which multiplexes to the pair of SATA ports and apparently adds cloning functionality.

Tagged: transporter, NAS, dropbox, connected data
Today Connected Data (makers of Drobo) announced NAS integration with their Transporter 75 and 150 business private cloud storage devices.
The premise of this addition is simple. Businesses can simply point a Transporter 75 or 150 unit at their local NAS device and have that storage accessible via the usual Transporter methods. These work very much like Dropbox, where files can be synced across systems or available from a remote source, except in this case the 'could' is provided by a box located and secured at the business offices.
Transporter devices can also be added to smaller branch offices or other locations. Those remote locations can keep a subset (or all) of the data from the main office, preventing the need to have a full copy of all data synced across each and every system. The Transporter Desktop app can map shared folders and access them straight off of the network. Shares can also be synced with a local copy if the user chooses to do so.
It's good to see Connected Data continue to develop this platform, and we hope to see this NAS integration feature added to the smaller capacity 15 and 30 models as this would help speed adoption and integration for smaller businesses that have started out with all content on a smaller local NAS.

ADATA's Premier SP600 SSD family is aimed at the budget conscious consumer, it is not often you see 32 and 64GB drives released along side the more common 128, 256 and 512GB models. The previous Premier Pro 128GB is selling for $50 so you can expect a similar or lower price for models with the new controller. Mad Shrimps benchmarked the drive and saw great results while the drive was fresh and empty of data but the performance dipped after the drive began to fill up. On the other hand at such a price and with a three year warranty you should not discount the drive altogether but there are certainly other choices at a similar price point.
"The new revision of the ADATA Premier SP600 SSD is incorporating one of the newer Jmicron JMF670H controller, which is accompanied by one Nanya NT5CB64M16FP-DH as buffer and also eight ADATA-branded MLC NAND Flash memory chips. Premier SP600 is meant for the entry to mainstream market and while the product succeeds to deliver good read speeds, it fails to impress in the writes department."

If you find yourself running low on space on your phone and need a handy way to extend your storage you could consider the Samsung Wireless HDD. A mere 19.9x89x126.5mm and 275g it won't take up a lot of space but will allow up to five devices to connect over 802.11 b/g/n WiFi to stream the content stored on the drive. It also has USB 3.0 connectivity to help you load up the drive before you head out on the road and you can even steal some of it's 7 hour rated battery life by using it as a charging station for your phone. Kitguru tested multiple streams and found that two simultaneous connections work perfectly but it is best not to exceed streaming to a pair of devices. The five device rating seems to refer more to the number of saved connections than to the number of streams you can run.
"While many users these days may have several terabytes of PC storage space, mobile storage is yet to catch up. Many phones come with just 16GB of internal storage, while 128GB is just about as good as it gets. This means most users simply cannot fit their media collections on their mobile devices – which is far from ideal."

Tagged: U.2, ssd, SFF-8639, pcie, NVMe, Intel, computex 2015, computex
Intel has announced that the SSD Form Factor Working Group has finally come up with a name to replace the long winded SFF-8639 label currently applied to 2.5" devices that connect via PCIe.
As Hardwarezone peeked in the above photo, the SFF-8639 connector will now be called U.2 (spoken 'U dot 2'). This appropriately corresponds with the M.2 connector currently used in portable and small form factor devices today, just with a new letter before the dot.
An M.2 NVMe PCIe device placed on top of a U.2 NVMe PCIe device.
Just as how the M.2 connector can carry SATA and PCIe signaling, the U.2 connector is an extension of the SATA / SAS standard connectors:
Not only are there an additional 7 pins between the repurposed SATA data and power pins, there are an additional 40 pins on the back side. These can carry up to PCIe 3.0 x4 to the connected device. Here is what those pins look like on a connector itself:
Further details about the SFF-8639 / U.2 connector can be seen in the below slide, taken from the P3700 press briefing:
With throughputs of up to 4 GB/sec and the ability to employ the new low latency NVMe protocol, the U.2 and M.2 standards are expected to quickly overtake the need for SATA Express. An additional look at the U.2 standard (then called SFF-8639), as well as a means of adapting from M.2 to U.2, can be found in our Intel SSD 750 Review.
It's been a while since we reviewed Intel's SSD 750 PCIe NVMe fire-breathing SSD, and since that launch we more recently had some giveaways and contests. We got the prizes in to be sent out to the winners, but before that happened, we had this stack of hardware sitting here. It just kept staring down at me (literally - this is the view from my chair):
That stack of 5 Intel SSD 750’s was burning itself into my periphery as I worked on an upcoming review of the new Seiki Pro 40” 4K display. A few feet in the other direction was our CPU testbed machine, an ASUS X99-Deluxe with a 40-lane Intel Core i7-5960 CPU installed. I just couldn't live with myself if we sent these prizes out without properly ‘testing’ them first, so then this happened:
This will not be a typical complete review, as this much hardware in parallel is not realistically comparable to even the craziest power user setup. It is more just a couple of hours of playing with an insane hardware configuration and exploring the various limits and bottlenecks we were sure to run into. We’ll do a few tests in a some different configurations and let you know what we found out.
