4TB Envoy Pro FX Portable Rugged External NVMe M.2 SSD Drive Thunderbolt 3, USB3.2 USB-C, up to 2800MB/s speeds, Drop/Shock Resistant Compatible with Mac and PC

Awesomely fast. Sustained 3Gbytes/second read or write with a MacBook Pro 3. It's annoying that the cable is permanently attached to the unit, but I understand that OWC don't want you to use just ANY old cable to connect it.

these drives offer fast no nonsense storage and are really solid. I haven't measured I/O speeds but for any musicians composers out there I am running 120+ Logic Pro tracks of large orchestral sample libraries, plugins and effects from these drives on my MacBook Pro without any latency problems or needing to bounce down. impressive. Not cheap but rec0ommedned

My 2017 iMac had become practically unusable, with a failing 1TB mechanical HD and 8MB of RAM. Attaching this as my boot drive has given it a new lease of life. Boot time, opening windows and apps are now a breeze. Genuinely surprised by the performance increase. Highly recommended for those he can't afford a new M2 Mac.

Blazing fast out the box on Thunderbolt 4 though not as fast as claimed but much faster than USB. both read and write speed were around 2300 according to Blackmagic speed checker. Switched on computer last evening to do some editing and drive would not mount on Thunderbolt. A call to OWC support confirmed the drive is a dead duck. I obviously did all the tests I could; tried it with different cables reformatted it using the USB connection that is 1/3 of the speed of Thunderbolt. Tried it on a different computer. No luck. It is, not a dead parrot, but a dead drive. It happens. It’s a pity as the drive is indeed built like a tank, but unfortunately a non working one on this occasion.

This drive is fast, for sure, but any USB-C cable seems very loose when connected to its single port. I just wouldn't trust that connection to last. The internal chassis behind the port doesn't seemed designed for durability. It's a shame - if the drive was updated with a snug, secure cable-to-port fitting, I would have kept it.

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 drive 2.) Add an internal SSD mounted in place of the existing SATA drive inside the iMac 3.) 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.

Extrem hastighet Med rätt anslutning. TB3 eller 4. Byggd som en tank.

Es muy rápido, cumple con lo que dice. Yo la uso para guardar librerías de instrumentos virtuales para composición y va muy bien.

見た目も質感も良い。 データ速度の速さは不自由なく使えている。

Petit SSD Tunderbold 4 un peu lourd mais respire la qualité... Time will tell 😉 Petit bémol cependant, la diode bleue/verte ne s'éteint pas à la mise en vielle de l' ordi et reste allumée tant qu'on ne débranche pas le câble. Note du 26 août 2025... Acheté en 2023 238,85€ 1T. Aujourd'hui, pile 2 ans > 354 € !!! A part cela fonctionne parfaitement
