You may remember the Silicon Motion SM2256 SSD controller that Al reported on during CES this year, even if you do not you should be interested in a controller which can work with 1x/1y/1z nm TLC NAND from any manufacturer on the market. The SSD Review managed to get a prototype which uses the new SM2256 controller, Samsung’s 19nm TLC planar NAND flash and a Hynix 440Mhz 256MB DDR3 DRAM chip. In benchmarking they saw 548MB/s sequential reads and 484MB/s writes, with 4K slowing down to 38MB/s for read and 110MB/s for write. Check out the rest of the review here as well as keeping your eyes peeled for our first review of the new controller.
"Controllers are the heart and soul of every SSD. Without one, an SSD would be a useless PCB with some components slapped on it. It is responsible for everything from garbage collection and wear leveling to error correction and hardware encryption. In simple terms, all these operations can be quite complicated to implement as well as expensive to develop."

Followers of PC Perspective have likely seen a pair of stories previewing the upcoming performance and features of USB 3.1. First we got our hands on the MSI X99A Gaming 9 ACK motherboard and were able to run through our very first hands-on testing with USB 3.1 hardware. The motherboard had built-in USB 3.1 support and a device that was configured with a RAID-0 of Intel SSD 730 Series drives.
We followed that up with a look at the ASUS USB 3.1 implementation that included a PCIe add-on card and a dual-drive mSATA device also in RAID-0. This configuration was interesting because we can theoretically install this $40 product into any system with a free PCI Express slot.
Performance was astounding for incredibly early implementations, reaching as high as 835 MB/s!
In that last article I theorized that it would be some time before we got our hands on retail USB 3.1 hardware but it appears I wasn't giving the industry enough credit. ASUS passed us a list of incoming devices along with release schedules. There are 27 devices scheduled to be released before the end of April and ~35 by the middle of the year.
It's a daunting table to look at, so be prepared!
The product categories are mostly dominated by the likes of the a USB 3.1 to 2.5-in adapter; that would be useful but you aren't going to top out the performance of the USB 3.1 with a single 2.5-in SATA device. Iomaster has one listed as a "USB 3.1 to MSATA & M2 SSD enclosure" which could be more interesting - does it accept PCI Express M.2 SSDs?
Minerva Innovation has a couple of interesting options, all listed with pairs of mSATA or M.2 ports, two with Type-C connections. What we don't know based on this data is if it supports PCIe M.2 SSDs or SATA only and if it supports RAID-0.
A couple more list dual SATA ports which might indicate that we are going to see multiple hard drives / SSDs over a single USB 3.1 connection but without RAID support. That could be another way to utilize the bandwidth of USB 3.1 in a similar way to how we planned to use Thunderbolt daisy chaining.
We don't have pricing yet, but I don't think USB 3.1 accessories will be significantly more expensive than what USB 3.0 devices sell for. So, does this list of accessories make you more excited to upgrade your system for USB 3.1?

It has been about a week since Al posted his review of the 256GB and 512GB models of the Crucial BX100 and what better way to remind you than with a review of the 1TB model, currently a mere $380 on Amazon (or only $374 on BHPhoto.com!). Hardware Canucks cracked open the 1TB budget priced consumer level SSD for your enjoyment right here, as well as running it through a gamut of tests. As expected their results are in line with the 512GB model as they both use a 4 channel controller, which does mean they are slower than some competitors drives. On the other hand the BX100 also has a significantly lower price making the 1TB model much more accessible for users. Check out their post here.
"Crucial's BX100 combines performance, endurance and value into one awesome budget-friendly SSD The best part? The 1TB version costs just $400."

Just over a week or so ago Allyn spent some time with the MSI X99A Gaming 9 ACK motherboard, a fact that might seem a little odd to our frequent readers. Why would our storage editor be focusing on a motherboard? USB 3.1 of course! When we visited MSI at CES in January they were the first company to show working USB 3.1 hardware and performance numbers that we were able duplicate in our testing when MSI sent us similar hardware.
But ASUS is in this game as well, preparing its product lines with USB 3.1 support courtesy of the same ASMedia controller we looked at before. ASUS has a new revision of several motherboards planned with integrated on-board USB 3.1 but is also going to be releasing an add-in card with USB 3.1 support for existing systems.
Today we are going to test that add-in card to measure ASUS' implementation of USB 3.1 and see how it stacks up to what MSI had to offer and what improvements and changes you can expect from USB 3.0.
USB 3.1 Technology Background
Despite the simple point denomination change in USB 3.1, also known as SuperSpeed+, the technological and speed differences in the newest revision of USB are substantial. Allyn did a good job of summarizing the changes that include a 10 Gbps link interface and a dramatic drop in encoding overhead that enables peak theoretical performance improvements of 2.44x compared to USB 3.0.
USB 3.1 is rated at 10 Gbps, twice that of USB 3.0. The little-reported-on nugget of info from the USB 3.1 specification relates to how they classify the raw vs. expected speeds. Taking USB 3.0 as an example, Superspeed can handle a raw 5Gbps data rate, but after subtracting out the overhead (packet framing, flow control, etc), you are left with ~450MB/s of real throughput. Superspeed+ upgrades the bit encoding type from 8b/10b (80% efficient) to 128b/132b (97% efficient) *in addition to* the doubling of raw data rate. This means that even after accounting for overhead, Superspeed+’s best case throughput should work out to ~1.1GB/s. That’s not a 2x speed improvement – it is actually 2.44x of USB 3.0 speed. Superspeed+ alright!

The sample size for the tests at KitGuru to see how well the OCZ ARC 100 SSDs stand up to their warranty are only five drives, now four as one has failed. The ARC 100 is rated for 20GB/day of host writes for 3 years, a total of 21.9TB and this one made it to about 322TB of writes before succumbing to errors. The other four are still going strong which lends credence to the claimed improvements that the Toshiba owned OCZ has made with their new SSD controllers. Even if you do suffer the death of a drive during the warranty period of three years the new hassle free ShieldPlus Warranty makes it very easy for you to get a replacement.
"The drives all passed the warranty figure of 300TB on 3rd February 2015 – but one of them has just failed with 322TB showing before failure."

Introduction, Specifications and Packaging
Micron's Crucial brand has been cranking out some great low cost SSDs for the past several years now. While their early drives pushed into the SATA 6Gb/sec interface before most of the competition, their performance was inconsistent and lagged behind some of the other more nimble solutions available at that time. This pattern was broken around the time of the M550 and MX100 launches. Those two drives were heavily competitive in performance and even moreso in pricing. Actually the pricing is probably the bigger story - when they launched, one of our readers caught a 512GB MX100 on sale for $125 ($0.24/GB)! We are coming up on a year since the MX100, and at CES 2015 Micron launched a pair of SSD models - the BX100 and MX200. Today we are going to look at the BX100 series:
Crucial aims to make the BX100 as their lowest cost/GB SSD ever - even cheaper than the MX100. Since Micron makes the flash, the best way to drive costs down is to use a lower cost controller. The Silicon Motion SM2246EN is cheaper to procure than the equivalent Marvell part, yet still performs rather well.
The Silicon Motion SM2246EN SSD controller
This is a great controller, as we have seen in our prior review of the ADATA SP610, Corsair Neutron LX, and Angelbird SSD WRK. From the specs, we can see that Micron has somehow infused their variant with increased write speeds even though it appears to use the same flash as those competing models listed above. We'll see how this plays out as the review progresses.

Tagged: Seagate, micron
The large storage companies have been teaming up for a while now, not simply through mergers and takeovers but also joint ventures between those who were once competitors. It is debatable if consumers will see much cost benefit from this cooperation but at least the products do seem to improve as specialties are combined. In this particular case we will see the traditionally disk based Seagate working with the flash memory maker Micron develop SAS products as well as SSDs for Enterprise customers. The idea of Serial attached SCSI SSDs is certainly interesting but in the current business environment you have to wonder how many companies will have the budget to invest in large scale migrations to flash based storage. It is far more likely this will bring new hybrid storage servers to the market, with SSDs in the front to provide bandwidth to frequently accessed data with HDD behind them for backups and cold storage. You can get a quick refresher on the other companies which have started cooperative ventures in the article at The Inquirer.
"SEAGATE AND MICRON have announced that they will join forces to work on projects together over a number of years."

Introduction and Background
We first got a peek of USB 3.1 at CES 2015. MSI had a cool demo showing some throughput figures including read and write speeds as high as 690 MB/s, well over the ~450 MB/s we see on USB 3.0 options shipping today.
We were of course eager to play around with this for ourselves, and MSI was happy to oblige, sending along a box of goodies:
Stuff we will be testing today (Samsung T1 was not part of the MSI demo).
For those unaware, USB 3.1 (also known as Superspeed+), while only a 0.1 increment in numbering, incorporates a doubling of raw throughput and some dramatic improvements to the software overhead of the interface.
Don't be confused between the USB 3.1 standard and the new USB Type-C connector - they are unrelated and independent of each other.
Yes, you’re all going to have to buy *more* cables in the future.
Type-C connectors will enable more simple cable design and thinner connections going forward but USB 3.1 will exist in both Type-A/B and Type-C going forward. Our benchmarking today will utilize Type-A.

USB 3.0, for storage, is fast. If you are using an external, spindle-based hard drive, it will perform basically as fast as an internal sibling would. Apart from my two SSDs, I do not even have an internal drive anymore. You can safely install games to external hard drives now.
But with USB 3.1, the spec doubled to 10 Gbps, which matches the first generation Thunderbolt connector. A couple of weeks ago, Tom's Hardware put it to the test with an ASMedia USB3.1 to SATA 6 Gbps developer board. Sure enough, when you are raiding a pair of Intel 730 SSDs, you can achieve over 700 MB/s read/write in CrystalDiskMark.
About the most interesting part of Tom's Hardware testing is their CPU usage benchmark. While USB 3.0 on Intel's controller choked a CPU thread, USB 3.1 on ASMedia's controller did not even reach half of a thread's maximum (the CPU in question is a Core i7-5930K Haswell-E at 3.5 GHz).
So until we get flash drives that are constrained by USB 3.0's fairly high ceiling, we might be able to have reduced CPU usage.
