This article analyzes why BackBlaze uses enterprise hard drives. The content is detailed and easy to understand. Friends interested in "Why BackBlaze uses enterprise-level hard disk" can read it slowly and deeply along with the idea of Xiaobian. I hope it can help everyone after reading. Let's learn more about "Why BackBlaze uses Enterprise Hard Drive" together with Xiaobian.

Famous foreign cheap cloud storage manufacturers have just announced the hard disk data statistics of 3Q 2017. Let's share these statistics.

First look at Q3 hard disk failure rate statistics, we see that the overall bad disk rate is about 1.84%. Overall, HGST has a better bad disk rate than Seagate, but why does BlackBlaze use so many Seagate drives? Because it's cheap, haha, there should be a reason for the supply.

In terms of capacity, BackBlaze uses the most 4TB hard disk, but it is also slowly being replaced by 8TB hard disk. This means that the price/performance ratio of 8TB hard drives should exceed 4TB hard drives.

If we look at the cumulative hard drive failure rate, we see that the Japanese hard drive failure rate is lower. However, Seagate's failure rate has also improved significantly.

BackBlaze basically didn't use enterprise-class hard disks, but now it suddenly uses a lot of enterprise-class hard disks. Why?

We see that in fact, the failure rate of enterprise-class hard drives is not superior at all, and it is almost the same as that of consumer-class hard drives.

8 TB Consumer Drives: 1.1% Annualized Failure Rate

8 TB Enterprise Drives: 1.2% Annualized Failure Rate

And enterprise-class drives consume more power and are more expensive than consumer-class drives, so why did BackBlaze start using enterprise-class drives in large numbers?

BackBlaze summarizes the following points:

Enterprise hard drives are priced down and within their budget; and enterprise hard drives have a warranty of 5 years, compared to 2 years for consumer hard drives.

Enterprise hard drives are faster, and their internal usage statistics show that with enterprise hard drives, the amount of data loaded per day increases by 40%. Therefore, we do not think that the speed is the same, the speed is the same, in fact, it is not, because the enterprise hard disk has a relatively large cache, the processing capacity of the command is also stronger, so there is still an advantage in performance.

3. Enterprise hard disk supports PowerChoice technology, so that it can sleep deeply when not in use, and the power consumption can be reduced by up to 54%. Below are the metrics for one of Seagate's hard drives, which we see supports multiple hibernation modes.

I share these today, mainly when I usually do storage projects, I often see users purchasing storage, and often ask for hard disks. Let's see if these requirements are reasonable.

1, requires the use of Seagate hard disk. In fact, from the above results, HGST hard disk is also good, and even the failure rate is lower. Therefore, I feel that users generally do not need to specify the brand, because storage manufacturers generally certify multiple manufacturers 'hard disks at the same time, random delivery, mainly for the stability of supply. Designated brands may cause delayed delivery.

2, requires the use of consumer-grade hard disk, reduce costs, this is especially in a lot of monitoring storage scenarios, very sensitive to cost. In fact, we see that enterprise-class hard disks still have advantages in performance and power consumption control. Therefore, enterprise-class hard drives are still worth the money. After all, consumer hard drives aren't designed for 7x24-hour scenarios.

About why BackBlaze uses enterprise hard disk to share here, I hope the above content can make everyone improve. If you want to learn more, please pay more attention to the updates of Xiaobian. Thank you for your attention to the website!
