SAMSUNG T7 Shield 4TB, Portable SSD, up-to 1050MB/s, USB 3.2 Gen2, Rugged, IP65 Water & Dust Resistant, for Photographers, Content Creators and Gaming, Extenal Solid State Drive (MU-PE4T0S/AM), Black

Great, durable, and fast little drive! Certainly perfect for what I bought it for. I exclusively use Samsung drives, and this is no exception to the quality expected. The included software is very limited, but Samsung Magician recognizes it.

It is a great external ssd and the price can not be beaten. But I do not know who is able to reach the advertised number. I have Intel 13th generation i9- 13900k CPU and z690 motherboard. It is the latest PC you can get. I tested the write speed on different USB ports. You can not reach the limit of 3.2 gen 2 speed which is ( 10gbps/about 1000mb/s). It reaches consistently around 640-680mb/s. So even I plug it into USB 3.2 gen2x2 (20gbps), it still caps at that speed. So do not bother with if you have the 3.2 gen 2x2 (20gbps) port or not. If you plug into USB 3.2 gen1 ( used to be called USB 3.0, 5gbps), it will drop to 300ish mb/s. So you do need a 10gbps USB port to fully reach its potential. But again it wont reach the advertised 1050mb/s. 650mb/s is a lot less not close. It is still amazing that it is faster than 2.5 inch SSD and you can editing video directly on it with plenty fast speed.

I love this SSD. Im a videographer and needed something portable, reliable, and tough to store hundreds of gigabytes of footage on. Ive had the storage drive for a few months now and its working well. My computer isnt the best, so write/read speeds are exceptionally slow, but when I hook it up to a more powerful PC it gets hundreds of MB/s. Im not worried about the speed as much as I am the reliability, though. So far Ive used up about 400GB and its going strong. Obviously, itll take longer to see if it withstands the test of time, but so far so good. Ive dropped it a couple times and it was fine. Also, it looks super cool. Its smaller than I expected.

This is the best portable SSD I’ve ever had. I’d buy it again in a heartbeat.

This 4TB SSD T7 SHIELD is a real POWER HOG and overwhelmed my Android smartphone with draw and did not even boot. But, once plugged up to my Wenter active power multi-USB dock it roared to life. My Samsung T5 has no problem hooking directly to my smartphone, perhaps the SHIELD is a little different design. Thx!

I use it to backup a 2TB drive on an M2 MacBook Air and with the “Time Machine”, this external drive works pretty fast.

This Samsung external hard drive is extremely fast and reliable for video editing. I recommend this product!

Just to get the good fundamentals addressed first, yes, this external SSD is overall fantastic. Even with its protective shell, its an easy every day carry. I′ve transferred over 400GB to it already and its crazy fast, while never warming up too much. The cable it comes up with is really nice quality and stays connected without easily pulling out. It′s already serving me very well as a back up for my phone. Now lets talk about the app, which, unfortunately, we cant divorce from the product itself since the app is what allows you to encrypt and rename the SSD and update the firmware. It′s terrible. From the confusing two similarly named apps on the store, to the lag, to the keyboard that vanishes when trying to type in the password (at least on Android), to the annoying disconnection error messages that tell you to reboot your phone, to the barebones operations inside the app. You can still use it well enough to do the jobs you need it to and use a file manager separately, but its such a hostile user experience that I could only recommend people use the app after thorough warnings on what to expect and thats pretty unacceptable from a major manufacturer like Samsung. Overall though, a great backup option for people who want local storage with peace of mind.

Feels quality with the new version. rubber and metal. Awesome build quality. I tested this HD and Im getting around 400 up and down. Im not getting 1050 at all. And on Youtube people are complaining about it. I bought it because I had to. And thought Samsung was and is superior to other brands.

In debating between this T7 Shield, the T7 Portable Ive been eying, and another SanDisk Extreme drive, I opted to go with the one on sale, since performance should be similar enough: an NVMe drive with USB 10 Gbit/s connectivity. At first I was a little unimpressed with the performance of the drive. But then I realized, I was connecting this to a Mac with the drives factory EXFAT formatting. In my experience Macs dont perform as well as Microsofts own EXFAT drivers built into Windows, and the difference can be a couple hundred megs on the sustained writes. Reformatting it as APFS required converting the disk from legacy MBR to GPT (easily done, if you Google how to in Disk Utility, or trivial if you just reach for a Linux box). After giving the drive a Mac native file system, performance was now on par with what I expected. Since my goal was to use this as a Time Machine drive, I didnt bother testing this under my Windows machine but expect performance would have been solid with Microsofts native EXFAT support. In terms of ruggedness, it looks like a fairly standard NVMe/USB assembly was wrapped up in hard plastic to be suitably sealed from the elements. If there was a plug for the USB port, I wouldnt be surprised if I could drop this thing in a pool and dive in after it. The lack of such protection for the port is probably why the drive is rated IP65, for dust tight, spritz it with water proof, not chuck it in the pool proof (IP67?). Where the hard plastized/rubber casing shouldnt chip and nick like a typical enclosure would from being bounced around, I wouldnt suggest pitching it out the back of a moving truck or out of a helicopter in flight. The plastic is hard enough that being carried around in a bag or used in a less than gentle workplace shouldnt be a problem. I bet it would be great for getting out in the world and doing photography in fairly remote places. For my purposes, the drive is expected to see see harsh treatment in the form of being tossed in a bag with other tech and deposited on a desk. So Im less in need of the durable enclosure than I am appreciative of the NVMe performance. But its nice to have a drive I know can take the rigors of travel. Much like my SanDisk Extreme Portable SSD and my old Transcend hard drive. Compared to the T7 portable that has a more normal enclosure, Id say get which ever one is cheapest or that looks good to your tastes. But if you actually do need dust, water, and drop resistance, go with the T7 Shield ;).
