External SSD choice: M.2 hard drive + adapter box v.s. Samsung T5

by Poster Mar 29, 2019 60
A 1T like the Samsung T5 costs about 1100, which contains SATA and is subject to the bandwidth limit of 6G. If you buy an M.2 hard disk such as WD's Blue 1T, it costs about 769 plus a box, it only costs more than 800, which is only subject to the 10g bandwidth limit of usb3.1, so it seems that an M.2 hard disk plus an adapter box is the best solution? I don't know if there are any mistakes in the analysis, I always feel that there is not such a good thing

    @ Anonymous1917 Thank you. I searched for it. It seems that there is no one on a certain treasure yet

    @ Poster More than 100 hard disk boxes, the promotion is 3.1 of the theoretical 1000M/second I think it's definitely not gen2 Having a severe fever But the write speed of 400 is enough for me

    @ Anonymous1914 Is it because of NVME fever? Why do those SATA hard drives feel that there is no heating problem?

    @ Poster Mine is intel760 Samsung should be hotter

    Don't compare the speed. There is not much difference in the speed of the current main control chip. Samsung uses its own main control, and most other boxes are VIA, JMS, and ASM. The main difference is the stability, high-speed reading and writing, and the main control chip The heat is also very large. You get what you pay for. If you pursue stability and high speed, you will be Samsung. If you pursue cost performance, you will be assembled. The price of high-end boxes plus high-end NGFF is close to that of Samsung.

    @ Anonymous1959 thank you. Is it that NVME has greater heat than SATA? Samsung T5 is SATA, right

    @ Poster It's hot when you don't use it, but it's hot when you use it. Don't listen to those manufacturers. Personal experience shows that the passive heat dissipation effect of these boxes can't keep up. This thing has too much heat. Summer is coming, and it is necessary to actively cool down. If you want to rely on a small hard disk box to passively cool down, you can only unplug it as you use it. After all, copying things is very fast. Also, I haven't bought the Blue you mentioned. I searched for it in a certain treasure and it's from NGFF? I'm not familiar with this agreement. But buy now why not use NVMe's. P.S. Now profiteers can't write USB3.0. After the name change, profiteers all write USB 3.1 directly and deliberately omit Gen1. Be careful, don't be misled.

    @ Anonymous1914 1000M/s is Gen2, and then whether your computer end support supports Gen2 is the decisive factor. Everyone has a Type-C shape, so you won't know it without looking at the parameter table.

    @ Poster nvme can only perform with Thunderbolt interface, and the price of hard disk boxes supporting nvme and Thunderbolt 3 is too high. The heat generation of nvme is much larger than that of sata interface ssd. When choosing a box, you must have active heat dissipation. In addition, there are not many computers that support the lightning interface. If you simply make a mobile hard disk, using nvme is too cost-effective. Generally, mac computers use nvme external hard disk as the system disk. Because the built-in hard disk of mac computers is too expensive, you can choose one With a small capacity, external large-capacity nvme is used as the system.

    I am also struggling with these two. The nvme usb 3.1 gen2 adapter box X treasure costs about 100 yuan. In terms of performance, I have read many reviews. If the SSD has no bottleneck, the speed is almost 1GB/s. The disadvantage is that it generates a lot of heat. Another advantage is that it will be easier to upgrade the SSD in the future. I am also considering Samsung's T5 solution. The advantage is that it is integrated and looks better. The disadvantage is that it seems to be an 860evo with a sata channel inside. Due to the speed limit of sata, the heating situation is unclear. Currently, I am using the msata + msata to usb3.1 gen2 adapter box, which will be hot for Windows to go. In addition, there is a thunderbolt 3 solution. At present, the price is too much, and the speed has been increased, but the price is that the price has increased several times, and the price/performance ratio is too low.

    @ Anonymous1916 I just plan to plug it in to the computer all the time without unplugging it. So, Samsung T5 is the best choice? After it's too hot, the speed and life will be affected, right?

    This mainly depends on the internal solid-state bus standard and external interface, even if you buy an off-the-shelf PSSD. Attached is a previously compiled list of SSD boxes https://docs.google.com/spreadsheets/d/1XqXU9mqIah0865b5b _ O5nm5u2gozaxEpXnDG29yJ2OI

    I bought the SL100 Pro just released by Lexa some time ago, with a speed of around 950 M/s
  • Poster Mar 29, 2019
    @ Anonymous10800 It should be nvme in this one, right? How about the heat after running at the full speed of usb3.1gen 2?
  • Poster Mar 29, 2019
    @ Anonymous358 Is nvme hot because the heat dissipation assembled by yourself is not good, or is the finished nvme mobile hard disk also hot? Like this sl100pro. Is the finished one now basic or based on sata?
  • Poster Mar 29, 2019
    @ Anonymous5122 Thank you for this. Are these boxes almost the same and can run full min (bus bottleneck, interface bottleneck)?
  • Anonymous4367 Mar 29, 2019
    HP P800 or Samsung X5 is a little expensive to own without any trouble
  • Poster Mar 29, 2019
    @ Anonymous1916 I looked at the finished box of NVME and basically has a heat dissipation structure. It means that NVME itself generates a lot of heat. I really don't understand that this M.2 has a miniaturized interface. I thought it could reduce the size, but it turns out that it generates a lot of heat and needs to rely on the radiator. The combined volume is larger than a SATA disk

    @ Poster is too hot. If the speed will be affected, it proves that the main control has the ability to adjust the temperature. However, there seems to be no hard disk boxes on the market now, so I said it should be equipped with a small fan to blow. Lifespan is definitely affected.
  • Anonymous5122 Mar 29, 2019
    @ Poster I think it mainly depends on the hard drive you have now, and what box you buy for what hard drive you have. If you don't need an external box to cut 4K video, the experience is basically the same. If it is the former, choose the box with thunderbolt interface.
