    I'm in the market for either of these and I deal with large files (4k footage, virtual instrument libraries, large sample files). Would an enclosure affect the speed in any way? I'm looking at getting an SATA III to usb c enclosure with a 6gbps interface.

    Samsung claims the QVO 1tb endurance to be 360TB. Some other manufacturers like Crucial MX 500 1TB which is a TLC SSD also claims to be 360TB. How this can be true?

    Então o EVO é melhor? E levando em conta o preço, qual o melhor?

    @15:40 That was a pretty terrible guess buddy. Half way through 2020 and ssd's cost more than double what you thought they would!

    Great video. That's precisely I only use Samsung drives, even for Rpi 4's as Evo 860 SSD, Evo 860 Pro SSD and Samsung 970 Evo plus NVMe drive. My entry level TLC SSD drive of preference is still Crucial MX500, mostly for experiments. I know they may be overkill for my PS4 Pro, Rpi 4's, Odroid-N2 and even for my Lattepanda Alpha, but who cares since I love squeezing every extra MB/seg out of them.

    If you're worried about the TBW/Durability I checked my SSD's TBW after a month of owning it and considerIing it was under heavy use (windows and app and game installs) it still will last me 25 years… Not kidding. So don't worry about tbw

    Samsung as a company the comes with many caveats, like TVs and monitors constantly having quality issues or shortcomings yet they have a great advertisement department. Over priced electronics does not mean better quality 😶🙄😷😷😷

    bullshit comparison…who is going to use a drive that is always empty? u should test with the drive reasonably filled

  • Grimmer2006
    Posted 21 mins ago 11:45 am

    Nice and interesting and good video.
    But 72gb is NOTHING, come back when you need to transfer several terrabytes. This is where the speed really makes a difference 🙂

  • Chinh Nguyen
    Posted 21 mins ago 11:45 am

    hey, may i ask a question. buffer size 12gb when did it reset? I'm using for shadow play temp file. that buffer write it reset when I stop record or after I reset my PC ?
    If I use the PC all day then that buffer size won't reset until I reset the PC, right? Because temp files are continuously written.

  • Nefff
    Posted 21 mins ago 11:45 am

    What about large downloads? Like game files that are up to 200GB in size? Would the write speed be affected during the download?

  • PinnacIeSaint
    Posted 21 mins ago 11:45 am

    What he says makes a lot of sense but from what it appears to me is that he's connecting via a USB SATA cable which to truly test he should actually install the drive simply because of the USB limitations. From what I recall on the newest USB version it maxes at roughly 500gbs whereas a direct SATA connection should get higher speeds.

    4:55 EVO(TLC) is Made in Korea. It worth to be paid more already.

    I have a Samsung 1TB QVO drive and its fine for everyday use.(Browsing, Office work and gaming) I have never had the need to transfer 42GB or more of data at one go. Also I am using it with Samsung magician which uses a chunk of system RAM to speed it up, and it really flies along. I would certainly get another one.

  • ay1ism
    Posted 21 mins ago 11:45 am

    Did you paste the copied files from the SD card at thesame time on the two SSDs?

  • GoogleMeme
    Posted 21 mins ago 11:45 am

    Somebody really needs to make a research about how long it takes before these SSD keep data being turned off.
    Such technology should have a period after that cells lose charge and data becomes garbage. I wonder if it takes a weeks or months or years for data on SSD to disappear.
    My SSD is being turn on every week at least. It should self refresh itself when turn on. There is no such problem on HDD, coz they use very strong magnetic field and can keep data for years.
    HDD have another problem – mechanics can stop work (motor get stuck) after long enough storage. I believe newer SSD become less reliable, especially during storage being turned off.

    Also thanks Samsung for at least documenting SLC cache size. Many crappy OEMs don't even bother documenting such important parameter. As crappy LCD monitor OEMs which doesn't specify bitness of screen panel (6 bit + FRC or 8 bit).

  • JayzBeerz
    Posted 21 mins ago 11:45 am

    most companies and stores never list if a ssd is slc, mlc, tlc or qlc so it makes it hard to make a decision on what to buy.

  • Lordspalse 007
    Posted 21 mins ago 11:45 am

    Pls does the dram and slc cache in 2tb evo also facilitates read speed or is it strictly meant for writes only?Thanks

  • herman gaviria
    Posted 21 mins ago 11:45 am

    I'll update you on the price of the 2TB EVO today in 2020, today is 5/1/2020, Amazon is selling 860 EVO's at $346. The 860 QVO on the other hand is at $286. This is some fuckery because I was just about to buy the EVO when it was only around 260 dollars. Now let me tell you, I'm a student and this shit really upsets me, and with you telling me that QLC is not reliable idk what to do.

    I see at the end you're using Linux Mint – An excellent Linux which I also use (usually in a dual boot configuration with Windows 10) and thoroughly recommend for anyone wanting to transition away from Windows.

  • Alby Tastic
    Posted 21 mins ago 11:45 am

    Samsung claims up to 1400TBW for the 4TB QVO on their website: "and backed by a limited warranty of 3 years or up to 1,440 TBW"

    Does this apply to all manufacturers other than Samsung? How about NVM.e?
