[fw] Backblaze lists most reliable hard drives based on its massivecloud study
The results from three years of use were revealing: Western Digital's drives lasted an average of 2.5 years, while Hitachi's and Seagate's lasted 2 and 1.4 years, respectively. Even so, some of the individual Hitachi models topped the reliability charts. "Hitachi does really well. There is an initial die-off of Western Digital drives, and then they are nice and stable. The Seagate drives start strong, but die off at a consistently higher rate, with a burst of deaths near the 20-month mark," Backblaze wrote in its official blog. "Having said that, you'll notice that even after 3 years, by far most of the drives are still operating." http://www.computerworld.com/s/artic...dy?source=cwfb -- @~@ Remain silent.

Seems they had clocks to set them to break at precisely near a year, including warrantee replacements. Funny after 10, 15 years that the game still hasn't changed, other than SSDs as boot option only. |

Over the years, and with several dozen HHDs, I've had better luck with WD (blacks and reds only since they've been color coding) than with the others. Hitachi has been responsible for the worst experiences. Larc |

Hitachi has been responsible for the worst experiences. Hitachi took over IBM. I didn't think much of them, IBM, back when they started outsourcing to oddball places such as Malaya, Turkey, Pakistan, whatever...2- to 6-hundred MEG capacity circa;- switching to WD, I don't know, pre-1T drives, when WD had a defense contract and touted themselves for supplying the US Navy's needs;- after that, moving up to T-class, Seagates, whenever I can got them, FUJI and whatever else then that has garnered some decent reviews. Most of those, a few "green class" drives, couple blacks, sit off to the side for three storage docking stations (some of which work lower and won't hit 2T) -- all being either 1.5 or 2T drives. Those CompUSA WD's, short-term burn-out sales items, really burned my butt, though way back when, it's so probably time now I went back with half-a-mind better not to buy on impulse sales. I stocked up pre-typhoon, no more $59 2T drives, although I could handle a 3T for something less than a bill, WD withstanding, do-able deals now if for nothing more than a challenge of "software" partitioning it out on some transitional scheme with older, 1st-gen dualcores MB BIOS-es -- XP/SP1 complain or no W7 dependencies. Heh - Got to hold on to those things or they'll have you somewhere, in ****-for-shineolaland, floating off on some cloud service. |

Seagate acquired Samsung also back in 2011. Maybe they're still using different manufacturing sites despite the acquisitions. |

So you should replace half of your drives ever darn year? I didn't read it, although I'd hazard it's a case study in a 24/7 abuse scenario, likely networked and streaming for continuous access and non-stop rewrites. I've drives here, Seagate 200G capacity, that are going on 5-7 years continuous runtimes, 24/7, just without all that abusive activity. Quite the contrary, I'm a bit of a gearfreak optimizer, been messing with caches and compression schemes since Day1. Well...I did have one, so far, that's went belly up, I believe as a result of a failed, undetected front-case fan;- In any event, before this summer, I'm taking a Dremel tool, 1/8" shanks to cut out and customize the front plastic facade for all my cases, (including an expensive Antec), so I can be visually stimulated with the exactitude of what, precisely, the hell is going on. Zero drive-failure tolerance and a new leaf for paging through my newest book. (In any event, last study I looked at, I doubt would be radically unrevealing, on a concensus on HD-to-brand failure skews are there really aren't any: There are both plenty of bad and good drives in any batch/make, so just buy what you got and bring it along for today's lunch on Potluck St.) |

So you should replace half of your drives ever darn year? You replace them as the SMART statistics, or the drive performance, dictates. In my case, I replaced the same drive on a yearly basis, twice, and eventually got a clue and changed brands. We'll see how well that works out, in a year or two. In other words, it's adaptive behavior, until you find something you can trust. The nice thing about the drive "failures" here, is you can use SMART to get some idea whether the drive is in trouble or not. Whereas, I've had a few Maxtor drives which just failed in the period of a day or so (before a backup could be made). Modern drives can still fail due to firmware issues, but I detect that possibility, by reading forums where outraged users discuss the latest firmware issue (like forums.seagate.com). Example of a search term I might use, before purchase. site:forums.seagate.com st32550n firmware That's what you'd enter, if you were planning on buying a ST32550n hard drive from Seagate. Or maybe you'd search for "st32550n problem" or "st32550n spin down" or the like. If you want to view the SMART parameters, keep a copy of HDTune handy. That's what I use. The free version has enough capabilities, to keep track of your disk. The purchased version includes read/write capabilities. If you like the tool and want to reward the author. http://www.hdtune.com/files/hdtune_255.exe The ones in red boxes should be zero. The scale is not linear, and the value "zero" means "we haven't passed the threshold yet". The drive can spare out a *lot* of sectors, before problems show up in the red boxes. And for me at least, I hardly ever find a Current Pending Sectors problem. Which is baffling, unless the parameter just doesn't work right. http://imageshack.us/a/img10/2134/cffn.gif Some failing drives, you use the "benchmark" tab and benchmark the drive. The occasional downward spike in the graph, is OK. It is the nature of these benchmark curves, that they're interrupted by other activities on the computer. For example, when the benchmarker "crawls over" the pagefile, the computer may not behave quite normally there. And I don't know exactly why. In any case, if the area where your OS sits, the benchmark graph has a pronounced and sustained "bad spot", you might use that as a replacement criterion. On my last drive failure, that's why the drive was replaced. The two zero values in the red boxes, did not betray that failure was a possibility. SMART is not a guarantee of problem detection, merely an additional tool to keep an eye on. In the past, we wouldn't nave looked at SMART, and the drive would just seem to die one morning, taking all the data with it. That's how it used to work. Firmware issues can also cause abrupt failures, but at least for one of the firmware-based failures (data structure corruption), recovery of the drive was actually possible without disassembling the drive entirely. The drive in that case, had a serial interface with TTL logic levels, and a cell phone USB serial adapter could be used to "talk to" the drive, and give it commands. The command set is not documented, and some rocket scientist figured out what voodoo you had to type to reset the drive. Expect that very few drive problems, will be fixed that way. Without documentation of the command set, we haven't a clue what capabilities are in there. Paul |
