My usual reply is: “Never!” I then go on to explain that two factors work against this ever happening. The first is the fact that SSD prices are unlikely to ever match HDD price per gigabyte, which is the subject of a few posts on The SSD Guy, the most recent appearing HERE. The second reason is that most PC buyers find SSDs unappealing when they are shopping for a new PC because of the price difference between an SSD and an HDD of the same capacity.
There are six Continue reading
A very unusual press release crossed my desk last week. London-based SecureDrives has introduced a 2.5″ self-encrypting SSD that takes security one very large step further by physically destroying the flash chips within the SSD by remote command.
The flash chips are actually fractured, as is shown in the accompanying photo, which SecureDrives sent me to illustrate. Click the thumbnail to enlarge.
SecureDrives calls its product the SDSRDD which is short for Secure Drive SSD, Remote Data Destruction.
My first concern was that the product used some sort of explosive. The company put me at ease by explaining that the fracture process uses a rapidly propagating shock wave via a patented technology. They said that the fracturing process creates no safety issues at all.
The destruction command is initiated through a GSM receiver internal to the SSD. When destruction is required (i.e. the drive is lost or stolen) the SSD’s rightful owner sends a user-defined message or phrase to the drive from any phone in the world. The drive flips the encryption key and then fractures the NAND flash and security processor. The drive then returns a confirmation message to the phone. The destruction process is executed in milliseconds.
Readers may recall a post that I published two years ago about an external SSD from Runcore that over-writes the data in the SSD via a GSM command. The Runcore product uses over-writing, which can take minutes to perform, rather than a self-encrypted drive which is effectively erased in a few milliseconds. The Runcore product also differes because it does not physically damage the flash, and, as an external drive, it cannot be incorporated into a notebook PC’s housing as can the SecureDrives product.
It seems that secure SSDs are getting increasingly sophisticated over time. I eagerly await hearing about the next imaginative step designers will take to make their SSDs more secure.
This study breaks the market into 23 application types, and provides an explanation of each along with forecasts by major application category.
Virtualized systems will drive the greatest 5-year average unit shipment growth, at 85%, although the data center will retain its leadership in enterprise SSD consumption. Overall enterprise SSD unit shipments will grow at an annual average of 32% through 2018.
Since SSD prices are cost-based, with roughly 80% of the cost coming from flash chips, NAND flash price swings will cause Continue reading
On Thursday IBM announced its X6 product family, the sixth generation of the company’s successful EXA server architecture. A smaller byline of the introduction was the company’s new eXFlash memory-channel storage or eXFlash DIMM which is offered as one of many flash options available to X6 users.
IT professionals find it difficult to determine which SSD or flash array to buy or even whether they can get the speed they need from standard HDDs. There is an extraordinarily wide rage of IOPS (from hundreds to millions), latencies, and capacities, and this can be confusing. A new Objective Analysis report: How Many IOPS Do You Really Need provides, through a survey of IT managers and other end users, an understanding of the performance needs of various applications including IOPS, latency, and capacity.
This report answers questions that have never previously Continue reading
One popular argument to explain why SSDs have not displaced the HDDs in all PCs is that there isn’t enough NAND flash production capacity to support this business and there never can be.
This argument has been posed as long ago as 2007 by WD CEO John Coyne at an IDEMA conference (the source of this post’s graphic), SanDisk’s Eli Harari at the Flash Memory Summit in 2008, and Seagate‘s CEO Steve Luczo in a Forbes interview as recently as last April. These are captains of the industry. Their arguments make people stand up and take notice.
It’s a really flawed argument.
It goes like this: Continue reading
Not long after I started writing this blog I heard from Les Tokar, who runs The SSD Review. It seems that Les had been calling himslef “The SSD Guy” for quite a while before I started to use that name for myself.
Les was more than kind about my using the name as well, all he asked was for me to clarify that this blog and his are unrelated, which is spelled out with the disclaimer to the right of this post.
I find The SSD Review to be a font of useful information. If you haven’t read it, please give it a look.
As for Les Tokar, I offer a tip of the hat to a real gentleman and fellow blogger.
The SSD Guy has run across some confusion lately about fast erase on SSDs. It’s time to clear this up.
SSDs can undergo a very fast erase, and have had that capability for a number of years. After ruggedness this is probably the key reason the military is so enamored with SSDs.
Let’s say that you were out to capture a major terrorism kingpin and your helicopter crashed. How would you assure that the Continue reading
When I have a question about SSD retail pricing I know exactly who to consult. Andy Higgenbotham (pictured here) and his Price G2 service track HDD and SSD retail pricing and publish data to a very high degree of resolution.
Price G2 data has been used in another post in the blog: When Will SSD Prices Drop Below HDD Prices?
This company publishes weekly reports of pricing from all major HDD and SSD manufacturers (Seagate, Western Digital, Toshiba, Samsung, Intel, Micron, and the like) with information on market trends like this for the week of April 23:
Flat to increasing pricing continues throughout 2012. Only on the 512GB have we seen sustained price drops from Q1 and through Q2. The 512GB capacity currently sells for $1.05/GB in week 17.
Amid recent rumors of steep SSD price declines this service has served to disprove any notion that the SSD market is undergoing fundamental change. The SSD Guy highly recommends Price G2 for anyone whose business relies on timely and thorough HDD and SSD price tracking.
During Micron Technology‘s quarterly earnings call an interesting tidbit was revealed: PC OEMs and Micron’s sales channel partners are carrying SSD inventory from panic buys they made in response to Thailand’s floods.
It seems that Micron’s OEMs and channel partners expected the HDD shortage that resulted from the floods to create new market opportunities for SSDs. This is not an uncommon notion, and it was first discussed by The SSD Guy in a blog post early last November with another post added in January. It seems that the messages of these posts didn’t reach those OEMs.
Micron mentioned this because Continue reading
