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?
Lot of you have seen this already, but Backblaze continues to track HDD field reliability. This blog shows (to me) that they (Backblaze) are buying on price and reporting associated reliability. This table is their historical summary and a good representation of field reliability in a moderate workload enterprise application. Based on reli, one would expect HGST to be the products of choice, yet there are many more STX drives in the mix. I’d welcome alternative interpretations:
Host managed SMR hits the mainstream! Nice job from WDC on deploying the industry’s first host managed HDD at the highest capacity yet. Ever since Google’s ‘Disks for Data Centers‘ paper, we knew these products were coming and we can expect all HDD makers to deliver similar products. I hope these all behave similarly or the industry will be in for further share erosion. I suspect that a variant of the host managed approach will soon be available for SSDs as well.
A good discussion on some of the big things going on in solid state storage by folks who know. Enjoy! For regular technology updates, go to Jim Handy’s website. He also allows you to subscribe to his podcasts.
