  1. Question: If the SSD portion of the Hybrid dies, is the data on the Hard Disk portion of the drive still accessible?

  2. Arun Kumar

    It should be. I am yet to come across any statement that negates my theory.
    Anyway, it would be saved and not ruined so you can access it using special tools if it cannot be accessed directly. But I think the SSD, being just a cache, if dies, the data on Hybrid drive can still be accessed without any problem.

    Their could be a potential for data loss if the sad portion of the drive fails.

    If the data within the SSD is merely a backup of data on the HDD portion then the data loss would be minimal. However, if the data is only stored in the SSD portion then many important files will be lost.

    Based on the above points,
    SSDs are much faster compared to Hard Disk Drives
    SSDs are more costly compared to Hard Disk Drives
    SSDs can die without any warning so you may lose your data if not already backed up

    If you know of a Hybrid 4TB HDD that has a SDD cache that can back up the data on the HDD PLEASE let us know!

    The problem here from the two replies seems to be that some don’t seem to see what the cache portion of the drive is.
    The cache is a temporary store whilst the data is written to the disc, once written the cache is emptied.

    which would be a better option 1TB – SSD or 500GB Hybrid drive ?

    I know this is a fairly old post, but the answers seem to have died off…

    My understanding of the SSHD is not that it actually, physically stores data on the flash memory. After all, 8GB is nothing, I am not even sure that’s enough space to store Windows these days.

    From looking into it, it doesn’t store the data, only the cache information needed to boot up the program, much as RAM does.

    As such, if the SSD section dies, you shouldn’t lose any information as the data is physically on the HDD section.

    If that seems a bit confusing, think of it like this: Say you load Diablo 3. The game needs certain files to run. The drive learns what these files are and if you frequently use them, transfers the data to the flash memory, so it loads that ‘particular’ information much faster.

    The result is a drive that gets faster with your most common programs the more you use them.

    Apologies if I am wrong on this and feel free to correct me :),

    500GB Hybrid drive is the best option, since it’s cost is lower than an SSD. Things like Applications will run at almost the same speed as an SSD.

    It’s not “much costly,” it’s “much costlier” or “more costly.”

    appalling spelling full of grammatical errors. How could I ever take anything in this article serious?

  12. Jamie Powell

    lol appalling grammar.

  13. Jamie Powell

    He don’t know what he’s talking about “The technology used in Hard Disk Drives (HDDs) is cheap and hence you can get large amounts of storage space for low cost” LOL REALLY. MY SCSI hard drive are certainly NOT made with “cheap” components. Running for 8 hours now in a server and never switched off. The guy is an idiot. Needs to go back to school for his grammar / spelling and college for I.T. Idiot

    I bet the authors knows multiple languages and English is not his first one. How many languages do you know you turd? And anyway who the F cares about grammar! 😀

  15. Jamie Powell

    people who want to read something credible and reliable and those with the brains to interpret it. Clearly they don’t know multiple languages owing to the fact they cannot figure out the most basic most spoken one in the world 🙂 Regards

  16. Jamie The Poo

    You imbecile, the most spoken language in the world is Mandarin! Ever heard of it??

    Anyway be happy in your ignorance. Over and out.

  17. Jamie Powell

    1. Mandarin Chinese

    Native speakers (2010): 955 million
    Non-Native speakers: 194 million2. English

    Native speakers (2010): 360 million
    Non-native speakers: 603 million

    Depends if you go native or non speakers. Doesn’t require world war 3.

    It should be – “Appalling spelling; full of grammatical errors! How could I ever take anything in this article seriously?’
