depends on the number of platters not size. but since higher size usually means more platters, they fail more often

there are some models which are the same size and have a different number of platters though. you can't recognize them by serial# or anything however. "get fucked" - the jew hdd cartel

don't buy anything higher than 2tb and check hdd statistics to make sure it's not fucking up due to some stupid wd green friendly technology or similar retarded shit.

>>
>>45512962
Why would you take backblaze seriously after they reported that enterprise drives had a higher failure rate than consumer drives with a such a low sample size? If two fewer drives failed, then enterprise drives would be considered more reliable in their original analysis.
For their current drive reliability report, it was mentioned that they were ripping drives out of portable drive enclosures.

The only drives ever to fail on me were a 1TB WD Green and a 2TB WD Blue. WD Blacks, Samsung, Toshiba, even fucking Seagate still works perfectly, and they are all 1TB or more and 5+ years old.
>>
>>45513317


Personal experience with drives isn't necessarily a good indicator unless you've had hundreds of drives as a good sample size.

Here's the only real advice for buying HDDs:

Avoid Seagate at all costs.

Generally buy WD or Hitachi. Hitachi is owned by WD and WD has stated that they still operate as an individual company with a different product.

Avoid WD Greens, they are cheap and slow and prone to failure. blues are OKAY for normal computing but blacks are better and have a fantastic warranty which makes them worth the price. Reds are for good for mass storage but don't operate particularly fast unless you have them in a RAID configuration.

Don't buy anything over 2TB in a single HDD.


TL:DR buy WD Blacks
>>
>>45513595
i have a 4TB WD Black. how fucked am i?
>>
>>45513852
Take your data off now and toss that shit out.
>>
>>45513595
you could buy over 2tb hdd's if theyre in a redundant raid array.

Otherwise 2tb is the highest i'd go
>>
>>45513852

Not necessarily fucked at the moment, but you will be a loot sooner than if you got one with a lower capacity, or more importantly, a lower number of platters.

Then again, they where dirt cheap.
>>
>>45513877

SSDs are, and have proven to be more reliable than mechanical HDDs. All that bullshit you heard about limited write capacity and random issues have been fixed at this point. Hell, even when the limited writes were being spouted as the reason not to buy SSDs, they were still theoretically able to write more times than an HDD before failure.

SSDs use a level of parity to avoid issues like this. The higher capacity SSD you buy, the more reliable (generally) because of increased parity among the cells.
>>
>>45513900

With HDDs you generally get what you pay for. Seagates are cheap enough to attract people to buy them but they fail at a significantly higher rate.

You'll hear people say they've run Seagates for years with no problems and that could be true but it's all really a gamble when buying HDDs. You could buy a great and reliable Seagate but the odds are low. You pay a little bit more for a WD or Hitachi and you increase the odds you get a good and reliable HDD.
>>
>>45513893

Nope, just set the mode to AHCI in the BIOS and it should be good. Samsung makes the best SSDs.

I've got a 3TB that I read/write from every day, going on a year and a half old with no problems. Read/Write speed hasn't been affected at all.
>>
>>45514163

I'm sure it sucked, but that's part of being an early adopter of technology, there are bugs that come along with it. At this point, this is pretty much fixed and no longer an issue. Firmware fixes have gotten a lot of those bugs fixed as well as new hardware.

HDDs do handle power failure better I will give you that, but by a margin that is sort of insignificant unless you live in some 3rd world country whose power stations are being bombed.

My friend is a defense contractor and has done some testing of SSDs for a certain large company and he did mention that he was disappointed about the failure rates with power surges in comparison to HDDs. He mentioned that after about 20 SSDs started acting wonky while after 40 most were dead. I don't know what the rate was with HDDs but he said they were a lot more reliable in that field. This was about a year and half ago though so this information may not be relevant at this time for newer SSDs.

As far as other areas of testing he did on the SSDs, one was a rapid change in temperature from around 300 degrees for 20 minutes down to about -20 degrees for 20 minutes and said that SSDs performed better than HDDs. I don't know what sort of relevance this test has in the real world but it's sort of a testament to the reliability I guess.

Reads and writes were much more reliable than enterprise HDDs.
>>
>>45514163
>power failure
Get Crucials. They all have a failsafe for that.

SSD are the most reliable, especially for write-once backups. Problem is the price is much higher than an HDD and the capacity much lower.

I can't believe it's 2014 and we aren't using 1TB optical media. Seriously, what the fuck. We should be buying blank TB discs for a dollar at this point, but they've not even been released yet. Fucking slackers.

They're fine for long term storage too, assuming the amount you need to store is small.
>>
>>45513171
You are partially right, Platter size and number of platters both contribute the data integrity problems.

1) the more platters the more chance to fail
2) the bigger the platter the higher the chance a physical defect on the drive will actually touch written data
>>
>>45514645
The only thing SSD's are bad at is capacity for the price.
That's it.
They win in any other area from HDD's
>>
>>45514659
The amount is irrelevant unless you hook it up every some time so it relocates the information as SSDs do. The information will wear out or get corrupted if you leave it in a safe for 10 years due to how it stores information.
That's why NSA, governments and libraries use magnetic tapes, or in this case HDDs, because its physical and won't wear out or go away unless you shake it like an idiot and ruin the platters or piss moisture at it.
>>
Bullshit son, HDDs have the same issue; if you don't periodically rewrite them, the magnetic data gets weaker over time until you start getting read errors. It's common practice to take your HDD every year or two and flip the bits back and forth.
>>
>>45513900
same here. i bought a 3tb hdd because it was on sale for $60. god damn it.

>>45514743
Magnetic grains on HDDs don't lose their magnetic properties just like gold doesn't lose its color you stupid fuck.
>>
>>45514292
>I don't know what sort of relevance
Well one has moving parts and the other doesn't so the later is more reliable in temperature change, that basic physics and don't even need a dick head soldier to figure that out.

4TB drives are just fine. A WD black comes with a 5 year warranty. I've never lost a single WD black drive, to drive failure.

Right now I'm running 2x 1Tb, 2x 2TB and 1x 4TB.

As I run out of space I pull the oldest drive and replace with a new one.

Functionally the risk of drive failure is about the same, Back in the day when a 80GB drive was huge people were doing oh what if it dies. Now with 6TB drives people say the same thing.

Don't put a WD Red into a system, they are built for NAS and have time access errors.

I can't wait for a helium filled WD Black drive.

I'll just leave this here. The drives are all in good SMART health, they've had light to moderate use over their 9 year lives. This computer was build during the transition to SATA from IDE, so its using a modified SCSI controller to handle SATA which is why it comes up weird in speccy for the last one. They're all Seagate btw, last one is 160GB, first two are 80gb and in a Windows "RAID 0".

>>45514814
How does that even work? They sealed and pressurized the drive? I've never seen a drive that didn't have the little air hole for it to breath.
>>
>>45513279
The 840 also is still experiencing voltage drift, experiencing crawling read/write speeds, and has yet to be patched like 840 evo. The performance is the issue.
>>
>>45514839
The air hole is so things can expand under heat. The spindles themselves are sealed off entirely. I suspect helium filled drives will have some expanding airtight sleeve around them.
>>
>>45514839
Helium drives don't need to "breath" like normal air filled ones. Air ones breath to accommodate with changes in air pressure. They also reduce the friction on the drives making them quieter and much more reliable. This also makes it possible to put the platters closer together for higher capacity.

This. this is why you don't buy high capacity drives. It's a lottery- some are good, some are garbage. they of course make sure only the good ones from their best factories go to reviewers etc, and everybody else gets to roll the dice.
>>
>>45514770
No, but their orientation. The information is not stored in the magnetic properties but in the arrangement. And that decays with time due to entropy.
>>
So who the fuck is HGST? It says "A Western Digital Company" so I assume they are reputable. Is this how they rebranded Hitachi? I'm considering getting their 4TB as a backup drive for all my other drives.

It doesn't decay, what you are thinking of is demagnetization due to too densely packed magnetic domains.

>>
>>45515115
It is physical storage, arrangement of physical grains with magnetic properties. The only problem with HDDs was when you have too densely packed domains and this induces the grains to influence each other to change orientation over time and "demagnetize" so to speak. It doesn't have anything with losing magnetic properties just like gold won't lose color. Cobalt alloy fixed this, as did finding ways to avoid too densely packed domains.
So yes, the platters last a lifetime unless the head hits them and you fuck up the HDD via shaking, or shit gets fucked due to moisture.

The SSD is a different more complex story, it needs charges from time to time to make the information last and that's why it often rearranges data.

These aren't sponsored results. They use drives differently than you might, benchmarking other portions of a drive to determine its life in _their_ situation.

Some consumer drives will fare much better with constant writes than others will. Some drives will fail more often if they're spun up erratically. There might be voltage droop from a bad power supply that certain drives handle better than others, or you might be rougher with your drives than they're being.

I don't think their numbers are faked, they just don't apply to everyone.

Not really. There was some test of various SSDs and Intel is confirmed to use proper capacitors for proper shutdown. I use a Seagate 600 Pro which, though not included in that test, does have proper power failure handling advertised and in in hardware.

>>45514292
It didn't suck if you went with non-Sandforce drives which is why Intel and Samsung have such great reputations. They did proper testing and validation. Eventually Intel did adopt Sandforce in some drives and they had a decent reputation though I'm glad they are back to in-house relatively speaking.

AFAIK SSDs don't need heaters for cold weather operation and I agree with the reliability as long as you use drives that are known to be good.

>>45516677
Seagates had a reputation for being the most reliable but that was pre-2000. As the study I cited earlier suggested, maybe the Enterprise reliability stems from the fact that people are conflating the use of enterprise drives with their use in fault tolerant arrays.

>>45516903
The bathtub curve as found by both backblaze and the 100,000 drive study didn't exist. Failures over time just gradually increase.

>>45516650
I do have a UPS. ECC, ZFS, backup to Amazon Glacier too which I'm sure is more fault tolerance than whatever you are running.
>>
>>45512720

Yes.

Until 2 TB or whatever you want is a single platter.

>crazy unreliable

I don't think anyone in this thread works with HDDs enough to actually make a judgment regarding platters. I work for a fucking NAS company. Everyone uses 2TB or larger HDDs. You know what fails? Shitty HDDs like Greens. It has nothing to do with capacity. It theoretically adds more ways to fail. In reality it doesn't happen.

tl;dr this entire thread is bullshit
>>
>>45518354
>>45517872
>>45518275
you don't have to use GPT.
You only need bigger sector size. If you use 4kb instead of 512 bytes(legacy), your windows(I think even XP) can see up to 16TB with MBR.

>>
>>45518916
Why bother using MBR anymore anyway? Windows 7 has absolutely no problem booting from GPT on a UEFI system. I've been doing it for years. Unless you're running on a really old board, MBR is pretty worthless these days.

yes but only until recently. It's still relatively new. And x86 win7 cannot. So it's still kinda compatibility/legacy thing.

If they had 'crazy' failure rates, the company would fold, or stockists would just stop carrying them.. they don't want the hassle of mass RMA's and the bad rep that would carry on to them.

Don't forget to account for the rotational velocidensity, you constantly lose data due to this.

Buy a 2nd one and run raid-1. Because you will have staggered the purchase the chance of simultaneous failure is pretty small.

I don't run non-raid anymore except on throwaway installs, or machines that access important data only over nfs.

Pro tip: Use Speedfan's SMART data analysis feature to determine whether your drive is going to go tits up soon or not.

Speedfan goes farther than just SMART data by giving weight to different SMART data different weight based on the drive model to more accurately determine whether failure is imminent or not.

That rebuttal is full of shit. Backblaze's earliest drives were WD Greens, which would've gone into crappy rev1 racks just like the early Seagates. Despite that, the 4-year WD Greens have survived much better than the 4-year Seagates. Similarly, if you compare their Hitachi and Seagate batches of similar age and capacity, the Seagates fail at higher rates.
>>
>>45536339
Something about reds not moving data from sectors if they get fucked because the assumed purpose of reds is to use them in a raid array (for data redundancy). So if 1 sector gets fucked on 1 drive then data is on the other drive anyway.
