It is a server-class drive in an M.2 form factor, but it might be out of the price range for many of us as it currently sells from Dell for $468.65.
接下來是比較 SSD 與 HDD。這邊的比較中,兩者都是相同的用途 (開機碟 & 系統碟):
The SSDs and HDDs we are reporting on are all boot drives. They perform the same functions: booting the storage servers, recording log files, acting as temporary storage for SMART stats, and so on.
If you will be at DEFCON 30 in Las Vegas, I will be speaking live at the Data Duplication Village (DDV) at 1 p.m. on Friday, August 12th. The all-volunteer DDV is located in the lower level of the executive conference center of the Flamingo hotel. We’ll be talking about Drive Stats, SSDs, drive life expectancy, SMART stats, and more. I hope to see you there.
官方有提到,低於 250,000 drive days 以下的數據僅供參考,因為資料量太少,在統計上無法提供結論:
For drives which have less than 250,000 drive days, any conclusions about drive failure rates are not justified. There is not enough data over the year-long period to reach any conclusions. We present the models with less than 250,000 drive days for completeness only.
The answer: It was a group effort. To start, the older drives: 4TB, 6TB, 8TB, and 10TB drives as a group were significantly better in 2020, decreasing from a 1.35% AFR in 2019 to a 0.96% AFR in 2020. At the other end of the size spectrum, we added over 30,000 larger drives: 14TB, 16TB, and 18TB, which as a group recorded an AFR of 0.89% for 2020. Finally, the 12TB drives as a group had a 2020 AFR of 0.98%. In other words, whether a drive was old or new, or big or small, they performed well in our environment in 2020.
