Is WD being hands-off with the HGST drives? Why are they continuing to not inherit WD's poor quality?

Buck said it's operating independently. I trust his insight on the matter but I don't know why they wouldn't be replacing everything they do with HGST tech.

The data doesn't paint a very good picture of Seagate, yet they keep buying Seagate drives. Lots of people use their reports as the justification for not buying Seagate.

The most current report makes WD look worse. Once the 3TB "DM" Barracudas were removed from their pods, the rest of Seagate's drives fell in at approximately average levels of reliability, including the other 3TB Seagate models. If you read the whole post, they basically say that the Seagate drives still make the most sense because that 15% lower unit cost matters more for their needs than 50% greater per unit reliability (compared to HGST) based on the sheer number of drives they're using.

Some manufacturers may not be able to meet their volume demands either.

Yeah. They actually say that it has a lot to do with OEM availability from their channel partners.

They're not buying that many drives. They said they bought 16k drives last year? I can only imaging that Dell, HP, Levovo, etc buy orders of magnitude more drives. I can't imagine that the various HDD makers don't have the capacity to support their volumes. I'm sure they're buying from different channels though.

Consider that after the floods in 2011, these guys were going around to Sam's Club and Costco to buy up local stock so they could de-shell cheap external drives. I'm guessing they're not big enough to get the breaks they want/need directly from drive vendors or top-tier suppliers but too big for retail or consumer supply. I also wonder if publishing their reliability info strains any relationship they might have with drive manufacturers.

Or perhaps a "strained" relationship led to the publishing of their data? Or they want to get a better deal for HGST drives so massage the stats?

That's when they were small. I'd like to see a graph of their drive buying numbers per year. I'm sure they could get drives direct now.

I do not see HGST 6TB NAS drives listed in their data. I have several in my workstations and they've been fine but I'm a tiny sample.
I have one and it is rather oddly noisy. I'm concerned that an octo-RAD would be terrible.

I never understand their logic. Does the Backblaze just buy whatever is on sale that week? Most of the cheap drives are not designed for ser multi-disk environment with vibration detection and compensation, so how do they account for that?

They cost half as much enterprise drives and fail at a less than 25% (total) rate.
They've built their system around redundancy and can take the drive loses. Considering the number of drives that they buy, it's an acceptable trade-off.

I wondered how 99 drives recorded 12662 days of operation in a three month (90 day) period. You have to add back the figures from the Removed table to the closing Counts.
It's interesting how many 12 and 14TB drives seem to suffer from infant mortality, based on the Average Days to failure. The pattern suggests that after that, they're incredibly reliable.

Backblaze reliability for Q1 - 2023.
HDDs typically failed in under 3 years in Backblaze study of 17,155 failed drives
Seagate still stands out.

Storage is cool
I don't think that is correct takeaway. Plus the ArsTechnica headline is grossly misleading. They should have said something like "Of drives that failed, they typically failed in under 3 years." to be less misleading.
Also, "The drive with the lowest AFR[ Annual Failure Rate] (0.28 percent) and at least 2.2 million drive days is Western Digital Corporation (WDC)'s 16TB WUH721816ALE6L4 (Backblaze has 14,098 units)."
No, it's just showing that the most common age of failures is less than three yaers. That does not count the vast majority of drives that are still working. Their aggregate AFR is 1.40%. Other than the one 14TB Segate drive with higher than typical AFR, there is not a lot to practically separate them.Another necro thread rise...

Exactly, and the 16TB drives probably have limited hours as they would be newer drives.

From what I gathered, the reality is that Backblaze loses something like 1.5% of the drives it buys within three years. That's an astonishing level of overall reliability. Seagate drives are a bit less reliable, but they also cost less, so the relative value from their side very close either way.
