    I strongly suggest against hybrid drives. It's just added complexity
    and therefore more ways and parts to fail with time.
    If you considering to buy hybrid HDD, chances are high you simply
    want faster performance for your system. I don't see why to choose
    slightly better solution (hybrid) over fastest one (SSDs).
    For a system disk and\or laptop upgrade, I'd stick with plain
    MLC-based (2 bit) NAND 250GB+ SSD (or NVMe if your system allows
    it), because they have the best reliability+performance+price
    ratings. Try to avoid TLC-based SSDs because they have much lower
    reliability and performance in comparison to MLC-based SSDs, but
    also much cheaper. And completely avoid QLC-based SSDs, which are
    cheap, but slow and unreliable, similar to USB flash drives.
    Backup your data (obvious), monitor health of your SSDs using
    S.M.A.R.T. and you'll be just fine.
    Also, watch out for manufacturers who use dark marketing practices,
    offering MLC-based (3-bit) NAND in advertisement, which is
    non-sense, but in reality they should be called TLC-based (3-bit)
    NAND, and also avoid manufacturers who is hiding real TBW or DWPD
    ratings of their SSD products and offer only useless MTBF rating.
    By using TBW or DWPD ratings you can calculate how long SSD will
    last in your estimated work-load.
