In The Tech Report's ongoing SSD endurance challenge, three SSDs are soldiering forward. We have reached the thousand-terabyte mark, which is at least five times more than any of the survivors are rated for. These survivors: The Corsair Neutron GTX, the Samsung 840 Pro, and the Kingston HyperX 3K. Technically, the HyperX was able to reach 1PB of written data with performing only 716TB of actual writes, due to compression.

Of course, each of the drives are less-than prestine. The Corsair Neutron GTX 240GB was slowly decreasing in its "life" attribute since the beginning, claiming to be somewhere between 75% and 80% with a fairly linear decline. If this trend continues, the drive will reach "zero" at around 4-5PB of writes. That said, its read speed has substantially dropped from the time between 900TB and 1000TB of total writes, from 500MB/s to just under 400MB/s. Also, this "life" could drop substantially if the drive encounters reallocated sectors (which this model has apparently yet to do).

The other two drives are a similar, remarkably successful story.

The Kingston HyperX drive is reporting itself to be substantially worse off, within the last 10% of its life. That said, even though it claims to be pining for the fjords, it is still working and has only reported a couple of reallocated sectors, those occurring in the last 100TB of writes.

The Samsung 840 Pro seems to still be going strong, although it had more zero or "a couple" of reallocated sectors -- every hundred terabytes yields about 500 reallocations.

As always, this is just our brief discussion of what The Tech Report found out. Be sure to check out their full article for many more benchmarks, tests, and conclusions.

Computex 2014: Samsung 845DC EVO Enterprise TLC SSDs

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.

3840x2160 for Cheap!!

It has been just over a year ago when we first got our hands on a 4K display. At the time, we were using a 50-in Seiki 3840x2160 HDTV that ran at a 30 Hz refresh rate and was disappointing in terms of its gaming experience, but impressive in image quality and price ($1500 at the time). Of course, we had to benchmark graphics cards at 4K resolutions and the results proved what we expected - you are going to need some impressive hardware to run at 4K with acceptable frame rates.

Since that story was published, we saw progress in the world of 4K displays with the ASUS PQ321Q, a 4K monitor (not a TV) that was built to handle 60 Hz refresh rates. The problem, of course, was the requirement for a multi-stream connection that essentially pushes two distinct streams over a single DisplayPort cable to the monitor, each at 1920x2160. While in theory that wasn't a problem, we saw a lot configuration and installation headaches as we worked through the growing pains of drivers and firmware. Also, it was priced at $3200 when we first reviewed it, though that number has fallen to $2400 recently.

IMG_0053.jpg

Today we are looking at the Samsung U28D590D, the first 4K panel we have seen that supports a 60 Hz refresh rate with a single stream (single tile) implementation. That means that not only do you get the better experiences associated with a 60 Hz refresh rate over a 30 Hz, you also gain a much more simple and compatible installation and setup. No tricky driver issues to be found here! If you have a DisplayPort 1.2-capable graphics card, it's just plug and play.

The Samsung U28D590D uses a 28-in TN panel, which is obviously of a lower quality in terms of colors and viewing angles than the IGZO screen used on the ASUS PQ321Q, but it's not as bad as you might expect based on previous TN panel implementations. We'll talk a bit more about that below. The best part of course is the price - you can find the Samsung 4K panel for as low as $690!

Using TLC flash to offer consumer level pricing to data centers?

Subject: General Tech | April 30, 2014 - 12:59 PM |
Tagged: Samsung, ssd, tlc

Samsung has been working with TLC flash for a while now, both the original 840 and the 840 EVO utilize that type of flash, the increased yields offer lower pricing at the cost of a reduced number of writes before the flash begins to fail.   The Register has posted their announcement of a new product line aimed at the data centre; the PM835T family will come in 240GB, 480GB and 960GB models and will also use TLC flash, with pricing predicted to be comparable to consumer level drives.  With Samsung's 10nm-class TLC flash the experts at SMART suspect a 500 phase/erase cycle lifetime however depending on how Samsung has designed the drives the actual number could be much higher, they do offer a 3 year warranty on their current TLC drives.  For now Samsung is not releasing an official expected lifetime for these drives which raises a question, will enterprise feel the short term cost savings are worth the long term replacement costs?

"Triple-level cell (TLC) flash chips mean fabs can extract more flash capacity from a silicon wafer, and so production costs are lower than for two-level cell MLC technology. Samsung says it gets "a 30 per cent increase in manufacturing efficiency compared to SSDs that use 2-bit NAND flash components."

Another 4K Monitor Option: Samsung U28D590D 28-in Display for $699

Subject: Displays | March 31, 2014 - 12:20 PM |
Tagged: deals, 4k, Samsung, u28d590d

Ever since CES we have been expecting an onslaught of 4K monitors to make their way to the market. Today Amazon.com listed the Samsung U28D590D for pre-order for the price of just $699. This is a 28-in display with a 3840x2160 resolution and support for 60 Hz refresh rates courtesy of the DisplayPort 1.2 connection.

samsung4k1.jpg

That's a hell of a deal for a 4K monitor, especially one capable of 60 Hz (likely through MST)! Worth noting is that the monitor is a TN panel so picture quality won't be as good as the IPS options still selling for over $2500, like the ASUS PQ321Q we reviewed previously.

The panel has a pair of HDMI inputs but both are listed as only supporting 30 Hz 3840x2160 resolutions without any mention of using them both simultaneously.  

You can find the full specifications list on Samsung's website, and we are working to get a sample in for testing in the next two weeks!

Fancy a preview of the Samsung Galaxy S5?

Tagged: Samsung, galaxy s5

Some lucky Aussies at The Register sweet talked their way into a Samsung Galaxy S5 and have put together a brief preview for your reading pleasure.  There are many new features you will someday be able to use, even if El Reg couldn't quite test them yet.   There is a battery saving mode which should help road warriors and a fingerprint sensor which is touted to work with NFC to turn your S5 into a replacement for your credit cards so you don't have to carry them with you.  There is more to see in the article, including the Galaxy Gear Neo smartwatch.

"This time around Samsung is keen on its battery-saving mode, IP67 rating and, once again, fitness features. Samsung Australia personnel swore blind all of those features were designed for an “Aussie lifestyle”. Because down here we all go to the beach every day, a supposition only slightly less believable than the notion that an S5 design meeting considered how to optimise sales in a nation of 23 million."

Samsung 840 EVO 1TB SSD for $469, 750GB for $388

Subject: General Tech, Storage | March 18, 2014 - 06:58 PM |
Tagged: ssd, Samsung, ocz, Intel, corsair

Back in January I wrote a short editorial that asked the question: "Is now the time to buy an SSD?" At that time we were looking at a combination of price drops with a lack of upcoming hardware releases. Since that published we have seen the release of the Intel 730 Series SSDs and even the new Crucial M550.  While those are interesting drives to be sure (review pending on the M550), they aren't changing our opinions on the currently available, and incredibly cheap, solid state options.

While looking for some new hardware for the office, I found that the 1TB Samsung 840 EVO is now at an all time low $469!  That is one of the faster SSDs on the market, and one of Allyn's favorites, for $0.469/GB!!  I have included an updated table below with some of the most popular SSDs and their prices.  

Series Capacity Cost/GB Price
Samsung 840 EVO 120 GB $0.69/GB $83 - Amazon
  250 GB $0.55/GB $139 - Amazon
  500 GB $0.51/GB $259 - Amazon
  750 GB $0.51/GB $388 - Amazon
  1000 GB $0.46/GB $469 - Amazon
Samsung 840 Pro 128 GB $0.92/GB $119 - Amazon
  256 GB $0.77/GB $199 - Amazon
  512 GB $0.74/GB $413 - Amazon
Intel 530 Series 120 GB $0.91/GB $89 - Amazon
  180 GB $0.80/GB $144 - Amazon
  240 GB $0.62/GB $149 - Amazon
  480 GB $0.87/GB $419 - Amazon
Crucial M500 Series 120 GB $0.57/GB $69 - Amazon
  240 GB $0.49/GB $119 - Amazon
  480 GB $0.47/GB $229 - Amazon
  960 GB $0.45/GB $439 - Amazon

The biggest price drops were seen in the higher capacity drives including, the Samsung 840 EVO 1TB and 750GB models, the Intel 530 Series 480GB drive and even the Crucial M500 960GB and 480GB drives.  Numerically the best value is with the 960GB Crucial M500 drive at $0.45/GB but it is followed very closely by that 1TB Samsung 840 EVO.  

evo1.jpg

As of now, the Intel 730 Series of SSDs is available for sale on Amazon.com but their price per GB comparisons don't really match that of the EVO or M500.  They are great drives, just read Allyn's review to see the proof of that, but they are targeted at the very performance conscious.  The Crucial M550 is brand new, and looks interesting; expect us to dive more into that line very soon.

For me personally, grabbing a 750GB SSD is incredibly enticing and I think I'll find a handful in my cart to update our older 180GB SSD test beds.

The fix was in, hope you saved those 14 year old receipts

If you bought RAM between 1998 and 2002 from Samsung, Micron, Hynix, Infineon, NEC, and Toshiba in the USA, you are entitled to a small payout, assuming you have proof of purchase.  The DRAM makers never admitted guilt and chose to settle out of court and you have until August 1st to follow the link in The Inquirer's story to put in a claim.  If you wish to opt out and sue them yourself you have until May 5th to do so but you might be better off taking the $10.
