Most Dependable Hard Drives? Understanding the Backblaze Tests

Today, information is viewed as perhaps the most valuable asset on the planet. With our lives turning out to be progressively digitized, the requirement for dependable information stockpiling is at an untouched high. Thus, while you're searching for a hard drive to store your family photographs, recordings, and different information, you need something going to endure. Be that as it may, how do you have any idea when you've tracked down a solid drive?

Looking at the situation objectively, one of the most outstanding ways of testing hard drives for dependability is to run an enormous number of them for a really long time and observe how they all passage. Obviously, that is not possible for most purchasers. However, Backblaze - a distributed storage and information reinforcement organization that was framed in 2007 - has been doing this for quite a long time with purchaser drives and sharing their discoveries openly for nothing.

Beginning With Context


Before we get off course, we should separate a few languages and add a touch of setting so you have a superior edge of reference proceeding.


Boot Drive - A drive that the PC boots the working framework from. Of the all out 206,928 drives Backblaze makes due, 3,760 were boot drives that were excluded from their drive details report.

Data Drive - A drive exclusively utilized for putting away information. These drives contain no working framework documents and are utilized independently to increment dependability and diminish free time on the off chance that working framework issues emerge.

As Backblaze makes reference to in its report, the organization oversees and gives details to 203,168 information drives.


AFR - The annualized disappointment rate (AFR) - totally unrelated to yearly disappointment rate - is basically the assessed probability that a drive will come up short during an entire year of everyday use. Thus, in the event that a drive has an AFR of 1.5%, it's probably the case the drive has a 1.5% possibility flopping during a time of purpose.

In the event that you're keen on the math, Backblaze offers a compact clarification and the recipe they use to work out the AFR in their 2021 report.

Backblaze's Findings - The 3 Most Dependable Hard Drives in 2022


Since it has become so obvious who Backblaze is and has some setting in regards to their report, we can dive into the information. We won't go through the entire rundown of drives. All things considered, we'll just momentarily cover the main three most reliable hard drives as per their information prior to checking another things out.

Seagate 6 TB ST6000DX000


Perhaps of the most established drive in Backblaze's arrangement, the Seagate ST6000DX000 appears to be an unshakable entertainer.

These drives strongly contrast the disappointment paces of a significant number of the other Seagate drives they're running.

With a typical period of 80.4 months (very nearly 7 years), the AFR of the drives is a simple 0.11%, with just 1 out of 886 drives falling flat during 2021.

16 TB WDC WUH721816ALE6L0

In spite of the solid senior Seagate drives Backblaze runs, the WDC WUH721816ALE6L0 is among the most youthful drives in the setup with a normal of only 5 months.

In any case, they gloat a comparable AFR at only 0.14%, with just 1 out of 1,767 drives flopping through 2021.

HGST 12 TB HUH721212ALE600

In Backblaze's server farm, the HGST HUH721212ALE600 takes third put on the dependability diagram.

At a typical time of a little more than 27 months (about 2 years), these drives have a noteworthy 0.27% AFR, with just 7 drives out of 2,600 flopping in 2021.

How Useful Is Backblaze Data for Consumers?

For more than 10 years, Backblaze has been in the large information industry.

They give point-by-point reports of how their drives perform through each quarter, as well as a yearly report.

More completely open Digital space than the untamed West . . . ern.


So clearly, the information they give is significant to average purchasers… correct? Indeed, perhaps not.

Varying Environments

Backblaze utilizes purchaser drives in a venture climate, making their measurements a blade that cuts both ways for customary buyers.

From one viewpoint, they have an enormous number of drives to test, and push them a lot harder than home clients would run them, loaning trustworthiness to their measurements. All things considered, in the event that a drive can deal with long periods of discipline in a server farm, then running one at home ought to be a similar cakewalk. But, in light of the fact that they're run in an endeavour climate, there are errors that can deliver their measurements mostly unessential to a home client.

Specifically, Backblaze is (probably) running their drives in a temperature-controlled, somewhat sterile climate. This implies they can tune their current circumstance for the ideal activity and life span of their drives. Contrast that with your home, where residue is more probable an issue, and the temperature and dampness probably won't be as steady (particularly on the off chance that you can't manage the cost of cooling), and you can see a difference between the two.

Obviously, we offer SSDs also


To additionally confuse things, you can see that there was an issue through 2021 with their 14 TB Seagate ST14000NM0138 drives.

They saw that the drives, put away in a Dell server, were bombing in higher-than-normal numbers, provoking their curiosity, yet Dell's and Seagate's too.

While they're actually examining the issue with a group of drives that bombed in Q4 2021, a fundamental examination from bombing drives in Q2 and Q3 uncovered that a firmware issue might have had an impact.


This exhibits how a product issue extraordinary to their setup, as opposed to say the least of the actual drives, might actually influence their outcomes such that isn't completely intelligent of a house what is going on.

Negligible AFR Difference for Home Users

The AFR contrasts likewise show little inconstancy between various brands and models of drives through 2021. The all out AFR across north of 200,000 drives is a small 1%, with the most noteworthy being at under 5% for the year (and those were the previously mentioned Seagate drives that appear to be novel among the weak drives).

For a systematic Backblaze, whose business as usual is purchasing and utilizing drives to back up others' information, this apparently minor error is really immense. Indeed, even shopper drives of this type aren't modest, particularly while you're purchasing a huge number of drives a year.

Nonetheless, for a great many people, a minimal AFR distinction like this is probably going to assume a lower priority in relation to execution, cost, and limit. Without a doubt, Backblaze values those things as well. That is the reason they run so many Seagate drives, in spite of what their evidently not exactly heavenly AFR appears to bring up (Backblaze has expressed that they offer a harmony among life span and worth).

In any case, most purchasers purchasing drives are on a similarly restricted spending plan, and aren't hoping to make money, yet rather, get the best value for their restricted money.

Backblaze is Leading the Charge for Change

Though many distributed storage and server farms all over the planet keep their drive disappointment rates to themselves, Backblaze is driving the charge to offer straightforwardness to general society.

And keeping in mind that Backblaze's system may not be the most extensive and engaging, they offer a brief look into a genuine setting.

It likewise offers a factual premise from a somewhat huge pool of drives without monetary motivation to slant information - a much-needed reprieve from clearly one-sided maker claims and a bunch of clashing tales around the web.
