    I'm looking to buy another external hard drive. My current model is 500 gigs, and I'd like the new model to be two terabytes or more in size.

    My question is whether or not external hard drives of this size are less reliable than your typical hard drive that is under a terabyte in size. Also do Seagate or Western Digital have better reputations in terms of producing reliable large external drives? Thanks.

    As far as I know there is not much difference in reliability.

    Only thing is that when you do HDD tests you can see that in the end it usually gets rather slow as the physical way for the reader to get to the data that is stored far outside is longer and I assume without knowing for sure that with more GB they just add one or two discs inside the HDD. So there is more space at the further away parts of a big HDD than on a Small one which might affect the speed but than again thanks to USB which is already really slow it won't make much difference.

    Here is a picture (not by me) where you can see the usual behaviour of a HDD

    It is getting slow in the end so I would assume that you would notice this more if you have more data stored on the slow part like if it only fits 10MB who would care but if there would be 10GB on that slow part .... that might hurt a little bit XD

    One thing I'm curious about is data recovery. By this I mean what if I purchased a two TB external drive and a couple years later the drive ended up dying. Is external hard drive repair a service that can be purchased? Or would it be possible to send the dead drive to someone, along with a new drive, and transfer the data from the old one to new one.

    Depends on what exactly is Broken but usually it is way to expensive if even possible ... best choice if you wish to be on the save side is to get a NAS and configure a RAID depending on your needs.

    RAID 1 would cut the risk of data loss due to a broken HDD while it would not prevent data loss trough a Virus or accidental deletion ...

    I'm not concerned about a virus or deleting something of value. But if I were to purchase your typical Western Digital 2 TB hdd are the odds rather good of hardware failure not occurring for several years?

    Also you stated that it would be expensive to repair the drive (depending on the issue of course). How much, worst case scenario, would you approximate it would cost to repair a 2 TB drive?

    Yes. But.

    Data recovery specialists and forensic techs can disassemble a drive in a clean room, extract the platter and retrieve the data from the platters. That service costs, at the low end, thousands of dollars. It's usually reserved for valuable corporate data or the retrieval of criminal evidence.

    A new hard drive, if used regularly, should last you at least half a decade. Intermittently or infrequently, it should last longer. I have a drive from 1986 that's still functioning properly.

    Ah well the chances of a defect is not bigger than with a small sized HDD
    and Repairing cost is high enough for many company to not tell you on their web page XD

    I have seen offers from 150€ for only looking if it is even possible to repair !
    It would be much cheaper to get a NAS and do a RAID1 or just get two HDDs and copy everything important to both ;)

    Raid one is a "mirror" so you need 2 HDDs of the same kind than every data you put on HDD1 is copied over to HDD2 (you PC would only show 1 HDD)

    True !

    I'm glad to hear that the chance of a defect isn't bigger as the drive size increases. I've had my 500 gig WD drive for about three years now without any issues. It's disappointing to see how expensive HDD repair is though.

    I suppose I could look into cloud storage. Google Drive is cheap and obviously there's a certain comfort level going with such a well known company. Are there any known key drawbacks to Google Drive (such as file deletion for copyrighted material).

    If you back up your data on a regular basis or use a RAID array like Youkai mentioned earlier you shouldn't have to worry. Storing your stuff "in the cloud" involves a layer of trust that I really don't have for a company like Google.

    well you could get yourself something like WD Cloud but I think it is basically a NAS ....
    http://www.wdc.com/en/products/products.aspx?id=1140

    And you can have good luck with your HDD and have it work nonstop for many years and someone else can have the exact same model running only one hour a day and have a defect after a few month ...
    Like every mechanical thing it is possible to break down and you cannot really tell when this will be.

    Here is a Grafic by BackBlaze where they compared some HDDs they use in their Cloud service.
    They say that they are using only normal HDDs no Enterprise versions.

    Well I do like the idea of not paying monthly fees. But since I'm owning the cloud device, rather than using someone's server, wouldn't I be in the same position of being screwed as I'd be with a broken external hard drive should the cloud device malfunction?

    well yes ... you could get the more expensive "my Cloud Mirror" by WD ...
    There is a Raid1 pre-configured so you would to have to destroy two HDDs the same time to lose your data ...

    What exactly do you plan to store on your HDD that you need such a high protection ???

    If you need to make company backups you could do RAID1 plus an external save on a Tape as most companys do it but a Tape Drive is Expensive and have their flaws

    Or get yourself as exaple that WD Cloud and an extra external HDD ! so you would have your ext.hdd and if this breaks you have the cloud and vice versa.


    P.S. if you don't care who can look into your data you could even connect the my cloud to dropbox and have a copy of your clouds data there as well ...


    Here a link to BackBlaze

    I'm actually pretty careful with my current external drive. But with any form of newer technology there's always a risk of it breaking down rather quickly. And when it comes to videos and audio collected over the years that would be a real disappointment to deal with.

    The My Cloud Mirror seems really promising though. Thanks for the suggestion.

    even if the risk of failure doesnt go up, there is more for you to lose if you break a 5tb hdd filled to the brim with data than a 500
    gb, still both would be unfun.
