SSHD vs. HDD

I'm currently in the market for a second drive for my Desktop computer. (My current drive being a 250GB SSD). I want the fastest drive possible without actually shelling out more money for another SSD. I'm currently between this Segate HDD and this Seagate SSHD.

So my main question is: Which of the above drives is faster, and/or do you have any other suggestions in terms of fast hard drives.

  1. The SSHD by far buddy! I have one, trust me, they're around 1-2 seconds slower than an SSD! That's way quicker than a HDD! ;)

    ^ I'm guessing you are using it as a OS + Program drive. In that case, yes it will boot to OS almost as fast as an SSD. For program load times you are at the mercy of what will fit into the SMALL 8 Gig Cache.

    Turtleshotz - I'm guessing you are going to use the drive as a storage drive.; Your overall experience will depend on How frequently you "call" the same file as Only upto 8 gigs of "files will be in the cache and these will be the most often used - all other files will load at the native speed of the HDD.
    Bottom Line, If you do call the same files repetitively then you will see a nice performance boost - if Not very little performance boost - U at the mercy of the caching algorithm. Personally, I find it better to couple a SMALL SSD say 32-64 gig that you can select which files to reside on SSD and a HDD for storage.
    This is how I've configured all my systems:
    .. SSD as OS + program drive
    .. 2nd SSD as a "working SSD" - Put my most often used data here.
    .. HDD for storage/backup
  3. Yeah I was considering the HDD mostly because the native speed was faster, being a 7200rpm drive. I'll probably mostly use this drive for playing games that aren't on my SSD and for storage. Since most games are bigger than 8GB, I don't really see how an SSHD would give much of an advantage.
  4. 7200rpm does not directly translate into speed. The rpm mostly influences access times.
    Larger drives will have denser platters, so they can transfer more data per revolution.

    Even the very best hard drives can sustain data transfer rates that are only 1/3 that of a ssd.
    In random I/o which is what the os does mostly, a ssd is 50x faster.

    Regardless, there is relatively little difference among mechanical drives from a performance point of view. If you want speed, and can afford a ssd, then that is the way to go. If you just want storage, then price and capacity should be the main metric.

    I see that. What is not known is how much capacity is required.
    A SSD makes a lot of sense for a second drive if a lot of capacity is not a requirement.

    Not a lover of internally cached HDD for a "data" drive. Their primary function was to be a OS + Program + data Drive allwing for improved boot times.
  8. Thanks for your help guys, I decided to get the HDD and an additional 120GB SSD. Thanks again.
  9. I have a more specific/related question.

    Would a HDD or a SSHD be better for my purposes?

    I need a secondary external drive. I have an SSD I use mainly for VM's, but I do need a larger capacity, secondary external. This will mainly be used for storage/backup, but I will probably only have 1 or 2 VM's on it (Whatever doesn't fit on the SSD).

    I'm wondering if an HDD with faster native read/write would be better or worse than a slower SSHD w/ 8gb of nand solid state.

    With mainly storage and a couple of VM's, will I really see a worthwhile performance difference with VM's?

  10. All hard drives perform about the same. Use them for low cost storage, not for performance.
