OWC Envoy Pro Elektron Portable 2TB SSD, Super Fast External SSD with up to 1250MB/s Performance, USB 3.2 Gen 2 and USB 2.0/3.0 Backwards and Universally Compatible, NVMe Powered Portable SSD

This one is expensive for the capacity.But it works at speeds that compare to external SSDsIt's well worth the cost if you think you might need to actually fill it up in a hurry.This one was a huge help when windows updates caused a complete inability to boot on a PC and I had to boot up a copy of Linux then copy all the data off it (because of course being windows it's quicker just to re-install from scratch than fix the mess the updates can make). It was recognized by an older version of Linux just fine and I was able to copy things quickly and get the system back up and running.If you are an IT professional, I'd highly recommend you have one of these in your pocket.

I purchased the 4 TB version to serve as the external drive on my Mac Studio M1 Max for my (large) Lightroom and Apple Photos photo libraries. The speed of this drive is exceptional and perfect for large photo libraries (78K in Lightroom, 37K in Photos). LightRoom images load almost instantly. There is no observable delay as you click from one photo to another. I'm just sorry that I didn't get this earlier. I have a number of OWS devices, and they have always been top-notch. Maybe a bit pricey, but the performance and reliability are well worth it.

it is perfect！

I needed to upgrade my 2019 Retina 5K 27" Intel iMac because the Fusion Drive had developed file directory hash errors that couldn't be resolved with Disk Utility First Aid, even after running First Aid for several days.I eventually backed up (externally and offsite) and reformatted the Fusion Drive and reinstalled MacOS to remedy the disk errors. But the disk errors seemed like a harbinger of a potential impending hardware failure, and time to consider replacing the aging Fusion Drive with newer, faster solid state drive technology. SSDs have come way down in price since I purchased my iMac.There are three good options for upgrading the 2019 iMac drive:1.) Add a Thunderbolt external drive and make it the boot drive2.) Add an internal SSD mounted in place of the existing SATA drive inside the iMac3.) Replace the NVME drive connected to the PCIe bus behind the iMacs mainboard. This small NVME drive is part of the Fusion Drive and acts as a sort of drive cache. But since it connects to the PCIe bus on the mainboard, it has the potential to be the fastest upgrade option by far.Installing these options increase in complexity in the order listed above. But the internal SATA replacement is actually slower than the external Thunderbolt option. The PCIe NVME option #3 is the fastest option, but the hardest to do. It requires almost completely disassembling and removing the innards of the iMac to access the backside of the mainboard. And due to the technical depth of the task, it's pretty easy to screw things up.I opted for the easy upgrade, Option #1.The OWC Envoy Pro FX ($300) was $60 more expensive than a SanDisk alternative (SanDisk Pro 2TB Pro-G40 at $240). At first I ordered the SanDisk to save money. But after reading about very many user complaints about failed SanDisk external SSD, I cancelled my order and ordered the OWC Envoy Pro. I'm glad I did.The Envoy Pro FX drive has incredible build quality. The enclosure is beefy, machined anodized aluminum. Very thick and massive as a heat sink. I didn't appreciate this until I held it in my hands and felt the weight and solid construction. Nice job OWC!BlackMagic disk speed test now shows Write speeds exceeding 1518 MB/s and Read speeds of 2664 MB/s on the external Thunderbolt drive. That's almost 3 times faster than the internal Fusion Drive.I recommend the OWC Envoy Pro FX drive. And I am no longer a fan of SanDisk due to the controversy about lost data. I already have a 4TB SanDisk Extreme Pro Portable SSD. But due to the stories online, there's little confidence in SanDisk reliability today.

Small and powerful, fast transfer speeds. Perfect storage device to take with you everywhere

Wanted something to use with Mac's Time Machine. Wanted to be able to restore the computer if something happened and backing up files to the cloud isn't the same as Time Machine. This did the job. Only took under 10 minutes to back up my entire hard drive. Granted its a new MAC so there's not a lot on it. The drive told me I should have bought a larger drive, twice the size of my current hard drive, but it's fine for what I want.
