    I have a friend who need so guides on SSD.

    I'll explains the key components on SSD.

    1st is controllers, they are the brains of SSD. I recommend marvell controller, they are the best but not budget. sadly, not sure about others cause I only buys marvell controler and UNIC controller to support china, for motherland. honestly UNIC is quite good, but I always buys the low end ones cause I'm poor.


    2nd is nand. there are 7 nand makers micron, Samsung, SK hynix, intel, Toshiba, western digital and UNIC.
    highly recommend UNIC to support china, they are really good, it's used in c200pro. but those are expansive. I usually used Micron last time but now mostly using UNIC downgraded nand which is by some unknown brands.

    than non essential parts.

    ram cache. they are good, with a ram of 1 gb can really speed things up. I don't use cache, cause they are expensive, but you should get SSD with cache, don't follow me. I build my own SSD and it's difficult to find controller boards with a ram cache for DIY builds.

    SLC cache. they are non recommended, all SLC cache now days are MLC mimicking SLC. as SLC don't exist any more. and even MLC mimicking SLC are rare as fuck.

    capacitor. used to be enterprise grade ssd. but.... not anymore. well capacitor protect data lost for power cuts. a good example in consumer grade is E200P.

    USSAGE.
    OP, you should make a partition on your disk to prevent your disk gets full. companies like Kingston likes giving disk huge OP.

    to @Maid Chan if you sill don't understand there are @lnv @Jeebus and @runsing comments below.

    If I have to recommend, all of Hikvision c2000 series are good, their E200P are good too.
    support china and buy HIKvision now.

    if you are china haters, Western digital blue SN500 use to be good untill they nerf it and make it slower I think they change controller, not sure.
    Toshiba RC 500 is the best value for money now. At least 2 month ago, with so call china and the rest of the world like this, not sure.


    EDIT: PLEASE SUPPORT HIKVISION. the company is facing bankruptcy from sanctions from donor trump

    yeah, cause thread is easier to be navigated compare to conversation.

    I wish it is, I would like it if western digital sent me $$ or at least sent me some HDDs for some texts online.

    It's amazing how this went from a help thread to a "fishy scam message" you see on emails.

    well, I just give up writing details guides on what is a controller for and how is it more important than speeds and how it works. it will take days to write in English and some of the terms might no be accurate. and most of all your would not even understands even after reading at most just reads 1/4 of it.

    And westerners usually don't have the concepts of 3D NAND, and NAND layers, and how there are bad/downgraded nand in the markets.
    non-nerd will have hard time understand the different architecture of nand. example bit-line, memories cells and source plates.
    it's like using a bit technical staff people will like, "your speaking alien language." so most people will like, so which one is the best? even after me explaining after 20 page of how SSD works. this is even true in chinese PC nerd community. so In the end the one who read it are the few regulars at the forum even then I believe they already know all of those.

    well, Normal consumers no need to know what are xtacking. and what are the 64 level cells and what's not. I'm just lazy too.

    Most people don't know what Quantitative Easing is.

    However, everyone seems to understand "Print Money". Except it's not printing money but it's close.

    However, not many people can describe how and why it works (or doesn't). Not that it would mattered to most people even though it is quite important.

    that's why I just listed a few models. cause there is no point to teach normies about that's affecting IO speed, and how all technology affecting each other.

    but hikvision is really heading to bankruptcy lol, look at the stock price before Trump ban Hikvision and after the ban on HIKvision.
