"Hard Drive Stats for Q3 2018: Less is More"
"Hard Drive Stats for Q3 2018: Less is More"
https://www.backblaze.com/blog/2018-...failire-rates/ "As of September 30, 2018 Backblaze had 99,636 spinning hard drives. Of that number, there were 1,866 boot drives and 97,770 data drives. This review looks at the quarterly and lifetime statistics for the data drive models in operation in our data centers. In addition, we’ll say goodbye to the last of our 3TB drives, hello to our new 12TB HGST drives, and we’ll explain how we have 584 fewer drives than last quarter, but have added over 40 petabytes of storage. Along the way, we’ll share observations and insights on the data presented and we look forward to you doing the same in the comments." That is a lot of hard drives. And no SSDs (cost ratio still too high). Lynn |

Back in 2016, looks like Samsung planned to get SSDs down to twice the cost of HDDs by 2020. https://www.extremetech.com/computin...levels-by-2020 A newer article: http://www.enterprisestorageforum.co...omparison.html shows an SDD is still, at least, costs 7.4 times that of an HDD. At Newegg, a Samsung 1TB EVO SATA3 SSD is $200 ($167 now on sale). A WDC 1TB Black SATA3 HDD is $100 ($73 now on sale). Not quite 7 times the price but about 2 times (so Samsung has exceeded their timeline). When replacing a single HDD with an SSD in your home computer to boost its performance, the additional $100 is a tolerable one-time cost per computer. Replacing 100,000 HDDs with SSDs would cost $10 million. |

The HDD I'm using in the PC posting this message is a 2.1GB Western Digital drive from the mid 90s (like the rest of the PC). -- __ __ #_ |\| | _# |

Replacing 100,000 HDDs with SSDs would cost $10 million. Isn't their average drive size around 7 or 8 TB now ? Aren't multiple TB SSDs very expensive still ? I just picked comparable capacities for SSDs and HDDs. There are smaller and larger capacities for both with an escalated pricing rate as capacities go up (or as an old drive ages and becomes more rare despite being smaller). At whatever comparable capacity, SSDs are still way more expensive than HDDs for any datacenter to consider moving to SSDs. SSDs typically use NAND flash memory. However, the much faster DRAM also constitutes a solid state drive but requires power to retain its content. SSDs are NVRAM. DRAMs are not. DRAMs would need a battery to be long-term NVRAM; however, batteries are chemical so they would need to be replaceable (of course, non-replaceable batteries means deliberate obsolescence which manufacturers like, just like for smartphones). Pricing for DRAM is even more horrendous than for NAND: 16 x 64GB DRAM modules to give 1 TB of storage would cost $14K. 1TB HDD = $100 1TB SDD = $200 1TB DRAM = $14K Even SSD (NAND based) and DRAM will get replaced eventually. Someday memristors may show up for commercial consumption. https://www.techradar.com/news/compu...d-ssds-1222632 |
