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

  @ Anonymous1916 Thank you. I feel like I'm inclined to Samsung T5 now. It has less heat. Otherwise, I don't know when I use NVME to burn out. I just want to keep it plugged in the imac and don't want to unplug it

  @ Anonymous5122 no SSD right now.. They are all new purchases, but I originally wanted to assemble them myself. The performance is higher when the price is similar. Now I feel that NVME is too heated. I still prefer to buy ready-made SATA-based external hard drives

  @ Poster nvme itself is hot...

  I am using Samsung T5, installed Windows to go, and it has been running stably for a year

  Does the computer have a lightning port?

  If it is not for video and audio editing, there is little difference in daily use between sata3 and Thunderbolt hard disk. If your iMac is not afraid of losing its warranty, you can consider disassembling it and replacing it with the hard drive

  @ Poster prefers the Samsung t5 solution, which often requires mobile plugging and unplugging, with stability first, followed by speed.

  @ Anonymous358 I also feel now that it should not be broken due to overheating. What I want to say is that does a built-in NVME hard disk like imac also have a radiator? A memory chip also needs a radiator. I always think it's too exaggerated...

  @ Anonymous4518 Mainly looking at the reply above, I feel that NVME can reach 950M using usb3.1gen 2, which is still quite different from sata's 520M
• Anonymous4518 Mar 31, 2019
  @ Poster Then let me repeat it, [If it is not for video and audio editing work, the difference in daily use between 950M and 520M is very small.]

  This is a typical barrel theory. The actual speed depends on the shortest board of the hard disk, hard disk box and computer First, clarify a few basic concepts: 1. USB3.0 (same as USB3.1 Gen1) rate: 5Gbps 2. SATA3 rate: 6Gbps 3. USB 3.1 Gen2 rate: 10Gbps 4. Thunderbolt 3 rate (half speed): 20Gbps Thunderbolt 3 speed (full): 40Gbps For hard drives using SATA3 protocol (2.5-inch hard drives or M.2 hard drives): 1. Just find a USB3.0 hard disk box. Maximum theoretical rate: 5Gbps 2. Perfectionists can use the USB 3.1 Gen2 hard disk box and connect the hard disk box to the USB 3.1 Gen2 interface of the computer to fully utilize the performance of the hard disk. Maximum theoretical rate: 6Gbps For hard drives using the NVME protocol (M.2 hard drives): 1. If it is only used on computers equipped with a Thunderbolt 3 interface, use a Thunderbolt 3 hard drive enclosure to maximize the performance of the hard drive. Thunderbolt 3 (half speed) Maximum theoretical rate: 20Gbps; Thunderbolt 3 (full speed) Maximum theoretical rate:: 40Gbps. As the speed of the hard disk is likely to not reach the interface speed, the actual situation is based on the speed of the hard disk 2. If it is possible to use a computer without a Thunderbolt 3 interface but with a USB3.1 Gen2 interface, only the hard disk box with a USB 3.1 Gen2 interface can be used at this stage. Maximum theoretical rate: 10Gbps. Thunderbolt 3 hard drive enclosures equipped with the JHL7440 Lightning Controller are not available until the controller is widely available 3. If it is possible to use a computer with only USB3.0 (same as USB3.1 Gen1) interface, there is a big hole here! A huge pit! A huge pit! The USB3.0 interface can only provide 5V, 900mAh power, but this power is less than the power consumption required by most hard disks using the NVME protocol. In this case, the hard drive is easily burned!!! Situations such as dropping speed are even more common. Never use it like this!!! At this time, the hard drive with SATA3 protocol should be used

  @ Anonymous10281 I am now equipped with a hard drive case + Samsung 970 EVO, the required current is 896mA, but the USB-C port of Macbook Pro can only output 500 mA, and my heart is broken.
• Anonymous10874 Oct 13, 2019
  @ Anonymous10873 Brother, if the current is not enough, how is the speed? I plan to use Orico hard disk case + 970 EVO Plus for mac

  Here's a word for those who have just stepped on the pit. If you want to attach an expansion hard drive to MBP, Samsung T5 solution is definitely better than NVME plus USB-C box. Although struggling with these two solutions, the price of T5 500G is similar to that of NVME 1T, so I bought a Crucial P1 1T plus Orico's USB-C box. The feeling is hot, hot, hot, hot, hot, hot, hot, hot NVME is really too hot. The main control chip is more than 50 degrees when it is turned on. When it reads and writes, it goes straight to 70 degrees. Orico's pure aluminum alloy box looks good, but the chip is so far away from the shell that it cannot dissipate the heat at all. Then the main control temperature wall speed limits, and the writing speed drops to double-digit MB/s. Stuffing a passive heat sink inside to allow the chip to contact the shell can improve a little bit, but unless you open the box and blow it wildly with a fan, it will be of little use. In terms of speed, the empty disk writing can reach 9xxMB/s at first, but it quickly drops to double-digit MB/s after the cache hits the wall with light and temperature. If you just copy a few gigabytes of movies each time, it will have little impact, and the data transfer is so slow that I want to cry, which is not as fast as my mechanical hard drive. The reading speed is not affected too much and can maintain 9xx. Returned it for T5. If you plan to hang on the computer for a long time, T5 is the best choice.

  @ Anonymous10875 Thank you for providing the information, but why is nvme so hot? The macbook is also nvme's hard drive, right? How does it solve the hot problem? I feel that the heat dissipation should be better outside

  Seeing that there are still people who keep collecting this theme, I would like to add it. Based on the suggestions given by everyone in their replies, I bought Samsung T5. I have been using it for more than a year now, and it is very stable. It has never been unstable when it has been plugged into the computer without unplugging it.
