smzdm上有网友给的链接，美国一个数据中心的人自己统计的，希捷故障率得令我肝儿颤，幸亏我的大多是4T的dm000，希捷的3T和1.5T是重灾区啊。接合使用日期来看，WD的红盘也阵亡率过高。妈的还是日本人靠谱，谁知道哪里能买到日立HGST的4T/6T 5200转硬盘

What is the Best Hard Drive?January 21st, 2015

It was one year ago that I first blogged about the failure rates of specific models of hard drives, so now is a good time for an update.
At Backblaze, as of December 31, 2014, we had 41,213 disk drives spinning in our data center, storing all of the data for our unlimited backup service. That is up from 27,134 at the end of 2013. This year, most of the new drives are 4 TB drives, and a few are the new 6 TB drives.Hard Drive Failure Rates for 2014
Let’s get right to the heart of the post. The table below shows the annual failure rate through the year 2014. Only models where we have 45 or more drives are shown. I chose 45 because that’s the number of drives in a Backblaze Storage Pod and it’s usually enough drives to start getting a meaningful failure rate if they’ve been running for a while.

Notes:
The total number of drives in this chart is 39,696. As noted, we removed from this chart any model of which we had less than 45 drives in service as of December 31, 2014. We also removed Storage Pod boot drives. When these are added back in we have 41,213 spinning drives.
Some of the HGST drives listed were manufactured under their previous brand, Hitachi. We’ve been asked to use the HGST name and we have honored that request.

at Is A Drive Failure For Backblaze
A drive is recorded as failed when we remove it from a Storage Pod for one or more of the following reasons:
The drive will not spin up or connect to the OS.
The drive will not sync, or stay synced, in a RAID Array.
The Smart Stats we use show values above our thresholds.

Sometimes we’ll remove all of the drives in a Storage Pod after the data has been copied to other (usually higher-capacity) drives. This is called a migration. Some of the older pods with 1.5 TB drives have been migrated to 4 TB drives. In general, migrated drives don’t count as failures because the drives that were removed are still working fine and were returned to inventory to use as spares.
This past year, there were several pods where we replaced all the drives because the RAID storage was getting unstable, and we wanted to keep the data safe. After removing the drives, we ran each of them through a third-party drive tester. The tester takes about 20 minutes to check the drive; it doesn’t read or write the entire drive. Drives that failed this test were counted as failed and removed from service.Takeaways: What are The Best Hard Drives
4 TB Drives Are Great
We like every one of the 4 TB drives we bought this year. For the price, you get a lot of storage, and the drive failure rates have been really low. The Seagate Desktop HDD.15 has had the best price, and we have a LOT of them. Over 12 thousand of them. The failure rate is a nice low 2.6% per year. Low price and reliability is good for business.
The HGST drives, while priced a little higher, have an even lower failure rate, at 1.4%. It’s not enough of a difference to be a big factor in our purchasing, but when there’s a good price, we grab some. We have over 12 thousand of these drives.

Where are the WD 4 TB Drives?
There is only one Storage Pod of Western Digital 4 TB drives. Why? The reason is simple: price. We purchase drives through various channel partners for each manufacturer. We’ll put out an RFQ (Request for Quote) for say 2,000 – 4 TB drives, and list the brands and models we have validated for use in our Storage Pods. Over the course of the last year, Western Digital drives were often not quoted and when they were, they were never the lowest price. Generally the WD drives were $15-$20 more per drive. That’s too much of a premium to pay when the Seagate and HGST drives are performing so well.
3 TB Drives Are Not So Great
The HGST Deskstar 5K3000 3 TB drives have proven to be very reliable, but expensive relative to other models (including similar 4 TB drives by HGST). The Western Digital Red 3 TB drives annual failure rate of 7.6% is a bit high but acceptable. The Seagate Barracuda 7200.14 3 TB drives are another story. We’ll cover how we handled their failure rates in a future blog post.
Confidence in Seagate 4 TB Drives
You might ask why we think the 4 TB Seagate drives we have now will fare better than the 3 TB Seagate drives we bought a couple years ago. We wondered the same thing. When the 3 TB drives were new and in their first year of service, their annual failure rate was 9.3%. The 4 TB drives, in their first year of service, are showing a failure rate of only 2.6%. I’m quite optimistic that the 4 TB drives will continue to do better over time.
6 TB Drives and beyond: Not Sure Yet
We’re beginning the transition from using 4 TB to using 6 TB drives. Currently we have 270 of the Western Digital Red 6 TB drives. The failure rate is 3.1%, but there have been only 3 failures. The statistics give a 95% confidence that the failure rate is somewhere between 0.1% and 17.1%. We need to run the drives longer, and see more failures, before we can get a better number.
We have just 45 of the Seagate 6 TB SATA 3.5 drives, although more are on order. They’ve only been running a few months, and none have failed so far. When we have more drives, and some have failed, we can start to compute failure rates.
Which Hard Drive Should I Buy?
All hard drives will eventually fail, but based on our environment if you are looking for good drive at a good value, it’s hard to beat the current crop of 4 TB drives from HGST and Seagate. As we get more data on the 6 TB drives, we’ll let you know.
What About The Hard Drive Reliability Data?
We will publish the data underlying this study in the next couple of weeks. There are over 12 million records covering 2014, which were used to produce the failure data in this blog post. There are over 5 million records from 2013. Along with the data, I’ll explain step by step how to compute an annual failure rate.

数据安全可不是闹着玩的

作者: momou 时间: 2016-7-27 09:06

是不是又是那家数据中心的？
当时说日立的硬盘损坏率低不是应为后期才换的，跟早起的希捷根本不是在同一起跑线上。

日立和东芝的硬盘好像一直不是多么靠谱，只不过用希捷和WD的人比较多用日立和东芝的人比较少，所以给人感觉好像希捷和WD的坏的多。

Hardware.fr 2015下半年法国通路硬件返修报告榜上HDD返修率：
HDD—机械硬盘恭喜东芝蝉联N次冠军
- Seagate 0,60% (上季度 0,68%)
- HGST 0,81% (上季度 1,16%)
- Western 0,90% (上季度 1,09%)
- Toshiba 0,96% (上季度 1,34%)
