    Your Disk Storage?

    Hey AnimeBeoples. I’d like to ask about how you deal with disk space at home.

    Do you prefer magnetic hard disks or solid-state drives (SSD)?

    How much storage space does your current primary fixed disk have?

    How many external drives do you have in active use? Their sizes?

    What is the volume of your biggest USB thumb drive (memory stick)? Do you use it only for data transfer or also data storage?

    How do you deal with your older HDDs, thumb drives etc. that still work okay but can only hold a fraction (say, less than one fourth) of the data amount stored on any of those devices you have in active use?

    I finally reached the level of terabytes, like, maybe two years ago and I’m sort of wondering whether there is any practical use for my older storage devices, especially those that hold less than 200 megabytes each. Also, I’m generally curious about people’s preferences and solutions. And I have been very close to getting an SSD but still decided to wait and see how they are, compared to magnetic hard disks.

    I have a 490 GB SSD which, over 2 volumes, holds my OS and programs.
    I have a 980 GB SSD for my games.
    I have a 2 TB HDD*
    I have 2 8 TB HDDs about to be set up in RAID 1, though I'd love to get a 3rd for RAID 5
    I have a 5 TB external HDD containing my anime, though I want to transfer that to my RAID

    For pen drives I have a Kingston Traveler of 32 GB, it's my emergency recovery stick so it holds a multiboot of several Linux distros, tools and anti-virus.
    I also have a 64 GB stick that has a bunch of portable apps and I use to transfer files between my phone and PC mostly.

    * I actually had 2 old HDDs (500 GB and 750 GB) in my PC but together with the external HDD from the quote I transferred everything to the 2 TB one and put that in my case instead.

    980GB SSD

    I have a 256gb SSD in my macbook for and a 1tb external HDD for audio samples. Only have a 8gb USB on me for small install files I need at work.

    I found the 490 for cheap, was quite happy with it so a week later I wanted to buy a 2nd one, but then then 980 one was on an even bigger sale. SOLD

    When practical, I prefer SSD. They're much faster and should generally live just as long as ye old HDD. Though, of course, they're more expensive and might simply not be an option.

    How much storage space does your current primary fixed disk have
    I guess that would be my 490 GB SSD (as it houses the OS).

    How many external drives do you have in active use? Their sizes?
    A single 5 GB HDD.

    How do you deal with your older HDDs, thumb drives etc. that still work okay but can only hold a fraction (say, less than one fourth) of the data amount stored on any of those devices you have in active use?
    Generally I try to move as much data to as large as possible drives so I have a fewer number of drives in use (see my earlier post going from 2 older in active- and 1 bigger in dis-use to the bigger one in active use and the older 2 not in use).

    ... I'm sort of wondering whether there is any practical use for my older storage devices...
    Well unless you're planning on building your own dedicated machine for something specific or have older hardware you want to keep in working order; probably not much practical use..

    I've just recently (last Monday), implemented a single 1TB SSD. But Also use a 3TB HDD

    Thank you for your replies!

    It seems as if the solid-state drive is finally making its breakthrough. The reason I have been interested in it for several years is reliability. I do not care so much about speed, even if that is a convenient plus. Price per gigabyte is not my highest priority either, especially as far as we think 250-euro devices or cheaper. What I value the most is a disk that stands both time and occasional rough handling (such as moving a laptop from one table to another without switching it off). Once or twice I was very close to buying an external SSD that felt rather expensive to me. But at first I could not find volumes big enough. Later I learned about their observed unpredictability in the long run, even though it seems clear that they are far more shockproof than magnetic hard disks.

    As for the old HDDs, sure, I could keep a couple as spare parts for the old Fujitsu Siemens box that serves me whenever I need to save something off some old floppy disk. The other vague plan I have in mind is putting two or more old HDDs together (is that called RAID or something?). But I guess if my actual storage device sizes vary from 0,5 to 2 terabytes, then using disks smaller than 100 GB as parts of the combo makes very little sense and sizes smaller than 50 GB are completely out of the question.

    a disk that stands both time and occasional rough handling
    An SSD should last you as long as an HDD, however due to the physical way it stores data they're unsuited as cold storage. Since SSDs store information via electrical charges, if the device has been unpowered for a long period of time (think 2+ years) the charge will have likely leaked away and the data is forever lost.

    (is that called RAID or something?)
    RAID (Redundant Array of Independent Drives*) works best using identical drives, so if you plan on rigging a few random drives together it's better to use JBOD (Just a Bunch Of Drives*). JBOD has the added benefit (over RAID 0, this doesn't apply to other types of RAID) that if a single drive fails you don't lose all data on the other drives as well. The computer literally stores whatever it wants on a drive and simply moves on to the next when it's full.

    RAID 0 'stripes' the data over all configured drives. So if you have 4 HDDs in RAID 0 with 16 kB chunk size a 4 MB file will have the first 16 kB written to drive 1, the second to drive 2, etc, the fifth 16 kB chunk to drive 1 again etc etc. Untill the 4 MB is spread evenly over the 4 drives in 16 kB chunks totalling 1 MB each.

    What this means though is that your OS can access all 4 drives at the same time to read and write you file (effectively giving you 4x your slowest drive's performance), but also that if a drive fails you lose a chunk of data every 4 chunks, making data recovery impossible.

    Quickly;
    • RAID 1 mirrors all data on both drives. Drive size = half total drive space. Drive performance = slowest drive. If a drive fails; replace and rebuild array (no data loss).
    • RAID 5 stripes data on all drives and adds a parity chunk, requires 3 drives minimum. Drive size = number of drives - 1. Read drive performance = number of drives x slowest drive. Write drive performance = Faster than normal, but slower than raid 0 as more data has to be written (even less performance boost without dedicated RAID controller). A single drive can fail completely, simply replace and rebuild.
    • RAID 6 stripes data on all drives and adds 2 parity chunks, requires 4 drives minimum. Basically RAID 5, but supports up to two full drives failing; simply replace and rebuild. This also means you're reserving 2 full drives worth of data for redundancy; number of drives - 2. Even with complex RAID controller writing performance is significantly impacted.
    • RAID 10 - This is essentially 2 RAID arrays in one. You have two RAID 1 arrays combined in a RAID 0 array (data is striped over array 1 and 2, but within each array, the data is mirrored on the 2nd drive). This requires 4 drives, but gives you the performance boost of RAID 0 and the redundancy of RAID 1. Though your usable drive space is like RAID 1; half the individual drives combined. It also has the added benefit of being quicker to rebuild than larger RAID 1 array (i.e. if 3 or all 4 were in a single RAID 1) or a minimum (3 drive) RAID 5 array.


    * The acronyms originally meant something slightly different, but this is more accurate.
