Paul Alcorn's Blog
After covering both Storage Visions and CES 2014 I have had a bit of time to reflect on the technology and subjects we covered at both shows. I was lucky enough to speak with industry leaders in both enterprise and client applications both shows, and today I bring you a roundup of our conversations. Feel free to click the links for greater insight into each topic.
SanDisk has made tremendous headway with their SAS Optimus line of SSDs, which are shockingly close to price parity with the high performance SAS HDD segment. SanDisk is also working closely with their partners to usher in the next era of business class SSDs. The burgeoning corporate market is ripe for the picking, and the increased TCO advantage outlined by Tarun Loomba from SanDisk is sure to come into consideration for just about every CIO in the planning stages of new procurement and system upgrades. The looming retirement of Windows XP is a huge factor in the corporate space, and migration to a newer operating system often requires new hardware. With their focus on business-class SSDs, SanDisk is striking while the iron is hot.

Between the Racks takes on SSD v HDD Endurance
The key to a great product evaluation is always going to rely upon comparisons. Coming to conclusions based upon the performance of competing devices is the bread and butter of what I do for a living. Writing a conclusion is elementary, provided you keep it simple. One merely rehashes the stats and chats a bit about the performance of Device A compared to Devices B, C, and D.
One juxtaposition we rarely cover is the comparison of an SSD to an HDD. In most cases, it is unfair to compare the performance of an enterprise-class SSD to an HDD. The performance isn't in the same ballpark, and until lately the price hasn't been either. We tend to keep the comparisons confined to similar devices. Plainly put, SSD vs SSD is a fair fight. It just doesn't seem feasible to prop up an HDD in the ring for a faster and more powerful SSD opponent to pummel to death.
With the continued development of MLC, and even smaller lithographies in the near future, the price-per-GB of enterprise SSDs has fallen into striking range of performance 2.5" SAS HDDs (10K and 15K). The tremendous pressures placed upon the 2.5" performance spindle-based market drags the SSD vs HDD comparison back into light.
In a recent article I was making some basic comparisons of an entry-level SAS SSD and a traditional 2.5" 15K HDD. Aside from the comparisons on price, capacity, and other features, one item really stuck out. While crunching the numbers it occurred to me that endurance isn't quite as clear-cut as one would expect.
I tend to be more of a nuts-and-bolts type of guy than a blogger. Most of the time you can find me in my cramped office, elbow-deep in a server, testing storage products. Luck, some great people, and a bit of hard work have combined to grant me early access to some of the most cutting-edge enterprise storage products on the planet.
Some guys design the engine, while others design the interior, and somewhere an executive smoking a fat cigar rakes in the cash from sales of the vehicle. In between there are a whole host of industry observers, marketers, and what-not. Everyone has their own unique role, and their own unique viewpoint.
Of course the enterprise storage industry is much the same, with similar voices all clamoring for your attention. They all want to bestow upon you, dear reader, their own spin.
Personally, if I could ask just one person for their opinion of a new car I would go to the test driver. He's the guy that, in Top Gun parlance, "kicks the tires and lights the fires". How fast does it corner? What's the 0-60, and not the specs please, tell me what you see and actually feel out there on the track. How does it handle?
