This is a guest post from Mike Montemorra, who is a technology guru with long and successful career in computer industry. Mike keeps an eye on the latest developments in computer and storage technology and publishes his observations weekly. Below is his brief summary of what was important in the past week.
What did we learn last week?
If you’ve ever wondered how flash cells are programmed, wonder no more and read this from YeeTech and the Memory Guy. The illustrative videos show why flash cell writes take so much longer to complete and highlights some of the ways bits can be transposed, causing errors that are sometimes tough for even LDPC to correct.

…and if you think programming an individual cell to its correct level is difficult, consider programming an array of cells at various levels. The reprogramming of a single bit (similar to what can be done with HDD) is the holy grail of solid state storage and is difficult to accomplish. This article from Jim Handy (The Memory Guy) discusses the critical role of bit selectors in storage class memories. They are a must have!
It looks like Samsung is on track to spend over $22.6B in CY18 on CapEx, much of this for their 7nm silicon fabs as well as for 3D flash. This is pretty amazing given the dire predictions of oversupply in the industry recenntly, but it looks like these guys are getting ready for the next semi boom! Something to ponder as we enter CY19, the first half of which may indeed be slow.
SMG QLC drive reviews show that this technology is marginally acceptable for client applications and probably not yet the ‘HDD killer’ technology promised for enterprise cold storage. Also, right now, it is a lot more expensive than HDD’s but it does play well right up to the point that the SLC saturates and QLC writes begin. Both Tom’s Hardware and Anandtech published reviews this week.
There’s a lot of hype in this HPE press release but it is another of the ‘smart’ enterprise storage systems in development. I don’t know how well this will work with complex mixed workloads, but I get excited when I see these kinds of announcements as it means the industry is ‘getting it’ and the world of smart storage systems is upon us.
Monolayer diodes: A pretty cool new semiconductor fab approach that should be compatible with next gen litho… can we say ‘Moore’s law extendibility’ for another few years? Pretty amazing so watch for associated technology improvements that would allow these to be built into next gen silicon.
Team leadership is always difficult, especially when you are new to the group. These tips are fundamental and useful, so take them to heart. Most importantly, foster strong working relationships with your team members so their efforts become not only collaborative, but synergistic… try not to duplicate efforts and stay on schedule!
Ultra high speed HDMI cabling is now on the market... I wonder whether the rated 4x 12Gb/s speed can be maintained after you twist and scrunch that cable around the back of all your AV equipment a few times…
Beware! ‘Secure’ websites do not mean they are not malicious! Take this example:
Krebs elaborates here, but always keep your guard up no matter what site you are on, especially during the holiday season.
