In the fall it was confirmed by Samsung that stale data on some 840 EVO drives would suffer performance degradation and released a tool to mitigate the issue which Al reviewed hereThe Tech Report recently heard of some cases of drives slowing even with the new EXT0CB6Q firmware installed and decided to investigate.  They took a 840 EVO 250GB SSD which had been filled with files to test the patch and was then left forgotten on a shelf for several months and tested the speeds.  The benchmarks showed an average speed between 35-54MB/s far below what you would expect to see from an SSD but in line with what users have been reported.  On the other hand another 840 EVO which has been in constant use since the firmware update shows no signs whatsoever of slowing down, though NTFS compression was recently used on the drive which could have refreshed the flash.  Obviously more testing needs to be done, keep your eyes out for updates on this new development.

"In October, Samsung patched its 840 EVO SSD to address a problem that caused slow read speeds with old data. Recent reports suggest the issue isn't completely fixed, and the results of our own testing agree."

Introduction, Specifications and Packaging


Today Samsung has lifted the review embargo on their new Portable SSD T1. This represents Samsung's first portable SSD, and aims to serve as another way to make their super speedy VNAND available. We first saw the Samsung T1 at CES, and I've been evaluating the performance if this little drive for the past week:


We'll dive more into the details as this review progresses.






The T1 comes well packaged, with a small instruction manual and a flat style short USB 3.0 cable. The drive itself is very light - ours weighed in right at 1 ounce.

If you have an entertainment system in your car, why not go whole hog and upgrade it with a specially designed Super Talent DuraDrive AT7 SSD.  Unfortunately you will be hard pressed to find one as they will generally be sold directly to the auto manufacturers but The SSD Review's look at it is interesting because it is the first look at Silicon Motion's new SM2246EN 6Gbps 4 channel controller.  The ATTO results when connected to an X99 motherboard were impressive, peaking at 554MB/s read and 446MB/s write.  It will be interesting to see which manufacturers install this in their vehicles and what usage scenarios would require this kind of throughput.


"Every now and then, we are fortunate to have SSDs reach our bench that one might not normally find within every day PC systems or servers. Our review today of the Super Talent DuraDrive AT7 SSD is just that; a SSD fully intended for the automobile industry, and more specifically In-vehicle Infotainment Systems."

Remember all those online 'experts' telling you that OCZ SSDs always fail?

The Tech Report has already shown a variety of SSDs can survive long after their write life cycle has been exceeded and that some drives can continue past 2 petabytes. Kitguru is performing a very similar test, specifically with OCZ Arc 100 SSD and have now passed the 100TB mark with the five drives they are testing.   Not a single one of these consumer level drives have died and only one of the drives has reported an error and that was one single bad  block.  While they have had problems with a specific controller in the past, they no longer use that controller and claims that all of their drives are tarnished is a bit of an exaggeration.  A specific performance was also finally addressed, but they are certainly not the only manufacturer that has needed to be called out to address performance degradation over time.  You can see the current results here.


"The drives all passed the warranty figure of 22TB at the close of December – our next test was to get them all past the 100TB mark. Would any fail?"

CES 2015: Crucial launches new MX200, BX100 SSDs, intros Storage Executive

At CES, I took a trip to the LVCC to be briefed us on a pair of new Crucial SSD models:


The new MX200 is an evolution of the previous MX100 line, with the most notable addition being Dynamic Write Acceleration. DWA can flip dies between SLC and MLC mode on-the-fly, and is detailed in our previous write-up of the Crucial M600 SSD. While the performance was a bit inconsistent in our M600 review, there have likely been improvements if Crucial is putting this feature into their mainstream consumer line. Also interesting is how Crucial intends to package this product in mSATA and M.2 form factors - these have historically been reserved for their higher end M550 line and were not available in the MX100.


Another addition is the BX100. For this drive, Crucial has decided on the Silicon Motion 2246EN, which should be able to let them get the costs lower than what is possible with the Marvell controller. As a budget targeted model, this one will only be available in the 2.5" SATA form factor. Below are the briefed specs from these two products;





Another addition is a software solution dubbed 'Crucial Storage Executive'. This is basically their 'Toolbox' solution and handles reporting of S.M.A.R.T. data as well as firmware updates. Crucial has chosen to go the unique route of configuring this tool as a background service that is accessed through a web browser on the host system (most competing solutions are a standalone application).


The best part of this launch is the pricing. Crucial SSDs have always been highly cost competitive, but look at that launch pricing on the BX100:


That's $0.40/GB for what looks to be a very decent SSD. These two models are set to ship Q1 2015, so we'll likely see them within the next month or so.

The full press blast for these pair of SSD releases appears after the break.

CES 2015: OCZ shows off new JetExpress SSD controller, Vector 180, Z-Drive 6000

Subject: Storage, Shows and Expos | January 9, 2015 - 02:36 PM |
Tagged: Z-Drive 6000, Vector 180, ssd, SFF-8639, sata, pcie, ocz, NVMe, M.2, JetExpress, CES 2014, CES

At CES, we stopped by OCZ and were briefed on their new SSD controller, the JetExpress:


As indicated on the placard, the JetExpress supports M.2 PCIe 3.0 x4 (M.2 is typically PCIe 2.0), and natively supports both SATA and PCIe / NVMe connectivity.


I found out some more goodies about this new controller. Aside from being configurable during production to support SATA or PCIe, this is actually a 10 channel controller (SSDs are typically limited to 8 channels). The controller can support LDPC *in addition to* BCH error correction. This is important as LDPC requires more compute power and is slower than BCH, so OCZ is baking in the capability to use BCH early on, and transition over to LDPC as the flash wears to the point where BCH can no longer efficiently correct bad pages. This means the JetExpress should be able to maintain very high performance while extending flash life out with LDPC only when it's needed.


Above is the Vector 180, which is launching soon. We are under NDA on this product, but nothing is stopping you from checking out the pic of what they had displayed above :).


Here's the Z-Drive 6000, an SFF-8639 (PCIe 3.0 x4) 2.5" enterprise SSD. The PMC Sierra controller supports NVMe connectivity and power modes are switchable to enable even higher performance. Performance looks to be very competitive with the Intel P3700, rated at 3GB/sec reads and 2GB/sec writes, as well as 700,000 4k random read and 175,000 4k random write IOPS. Our next OCZ review should be of the Vector 180, but samples are not out yet, so stay tuned!

OCZ's press blast for the JetExpress launch appears after the break.

CES 2015: Plextor announces M7e

Tagged: plextor, pcie, NVMe, Marvell 88SS9293, M7e, M6e Black, M.2, CES 2014, CES

Today Plextor announced the successor to the M6e (that we reviewed here) - the M7e:


The M7e uses the same Marvell 88SS9293 that will be in Kingston's Hyperx Predator, and the performance is certainly impressive:


1.4GB/sec reads and 1.0GB/sec writes. Plextor's demo compared to an identical testbed running a Samsung XP941, and the M7e was faster in nearly every performance trait.

Next up is a bit of a gorgeous refresh to the M6e - the M6e Black Edition:


The above photo was taken HDR, so the Black Edition appears darker than in the above photo. This is basically a repackaging of the M6e, in a housing that should run much cooler. Plextor got a bit creative designing this one, and they even added a SATA power connector - an option for those who feel their motherboard may not be providing sufficient power over the PCIe connector. Here's an exploded diagram for your viewing pleasure:


Plextor also announced an update to their DRAM caching solution, dubbed PlexTurbo 2.0:


Cached speeds were certainly impressive here, showing a roughly 2x improvement over the initial release of their software.

The M7e does not launch until mid-2015, but the M6e Black Edition will be coming *much* sooner, and we will have a review of the latter up within the next few days.

Press blast for the M7e after the break.

CES 2015: Silicon Motion SM2256 seen in action, capable of hybrid TLC/SLC caching

Subject: Storage, Shows and Expos | January 8, 2015 - 01:17 AM |
Tagged: CES, ces 2015, silicon motion, SM2256, ssd, tlc, slc

We first saw the Silicon Motion SM2256 controller at Flash Memory Summit, but now we've seen it live, in action, and driving several different types of TLC NAND.


Silicon Motion had this live demo running on a testbed at their suite:


The performance looked very good considering the 2256 is designed to efficiently push TLC flash, which is slower than MLC. As their representative was explaining that the SM2256 is currently being tested with Samsung, Toshiba, and SK Hynix TLC flash, I noticed the HDTune write trace:


Those familiar with HDTune and Samsung SSDs with Samsung's TurboWrite cache (from the 840/850 EVO) will recognize the above - the SSD begins writing at SLC speed and after that cache is full, the SSD then drops to writing at TLC speed. I specifically asked about this, as we've only Samsung flash provisioned with an SLC portion of each die, and the answer was that Toshiba and SK Hynix TLC flash also supports such a subdivision. This is good news, as it means increased competition from competing SSDs that can accomplish the same SLC burst writes as the Samsung EVO series.

We heard from a few vendors that will soon be launching SM2256 equipped SSDs this year, and we eagerly await the opportunity to see what they are capable of.

CES 2015: Mushkin launches Striker SSD, teases 4TB consumer PCIe, new M.2 and SandForce SSDs

Subject: Storage, Shows and Expos | January 8, 2015 - 01:00 AM |
Tagged: Striker, ssd, Mushkin, ces 2015, CES

At CES 2015, Mushkin launches their Striker 2.5" SSD product line:


The Striker is based on the Phison S10 controller, which should perform comparably to the Neutron XT that we reviewed back in November. We should point out that in the above photo, the Striker is sitting next to the Reactor, which is currently selling for $0.36/GB on Newegg.


This is a prototype of looks is to be a monster of a budget PCIe SSD. Using a Marvell SATA RAID chip to link four Silicon Motion controlled SSDs together in RAID-0, this beast is to (hopefully) be available in 960GB all the way up to 4TB capacities, and Mushkin is targeting $0.50/GB or lower when it launches later this year.


Details are slim here, but Mushkin is smartly jumping on the M.2 bandwagon.


SandForce has had their new controller in the works for far too long (we saw silicon demos like this last CES in fact), but we are hoping to see actual product released this year. Note this delay is solely due to delays in SandForce's development process.

Full press blast for the Striker after the break.

CES 2015: Storage Visions Sightings Part 2: OWC, Intel, Micron, Samsung

Subject: Storage, Shows and Expos | January 8, 2015 - 12:40 AM |
Tagged: storage visions, ssd, Samsung, owc, micron, Intel, ces 2015, CES

We covered some other Storage Visions sightings in a prior post, so now that a bit of the CES dust is settling down, here's the rest of what was cool to see at Storage Visions:


We'll start off with the Sonnet Tempo SSD Pro Plus, seen here with a pair of OWC Mercury Extreme Pro SSDs installed. This is a PCIe to 4-channel SATA HBA. The controller does not appear to employ RAID, leaving that functionality up to the host system OS. Two 2.5" SATA devices can be mounted directly to the PCB, and an additional two SATA channels are available through the rear panel eSATA ports. This card is marketed primarily as a storage expander for Mac products, and can be connected to a Mac Pro via a Thunderbolt-to-PCIe card expander.


Here is an ASUS Copper, which bridges M.2 (enclosed within a 2.5" housing) to a SATA Express link. This may be handy for current generation PCIe 2.0 x2 M2 devices, but with PCIe 2.0 x4 and 3.0 x4 SSDs on the horizon, a SATA Express device of this type will rather quickly become a throughput bottleneck.


Various recent enterprise SSDs. Bottom left is our first sighting of a P3500, sitting next to a Micron P420M, which is just below a Micron M500DC. The right side is all Samsung, and includes an XS1715, which is not SATA, but PCIe/NVMe via an SFF-8639 connector. There are a few M.2 units in the center, and what appears to be another 1715 HHHL unit (PCIe/NVMe) at the bottom right.

That wraps up the Storage Visions goodies. Stand by for more storage related posts as we comb through all of the press releases and photos from the meetings we attended earlier this week.
