OWC Envoy Pro FX External SSD 4TB NVMe, M.s Thunderbolt3 USB3.2 Gen2 USB-C Transfer Speed Up to 2800 MB/s

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。

今までiMacのHDDのみでしたが容量が足りなくなったのでSSDにしました。 音源読み込みも早くなってかなり快適です。

Mac Book用に購入しました この商品を購入する前はUSB 3.2 Gen 2のSSDを使っていましたが相性が悪いのかそれほど読み書きが早くはありませんでしたし発熱が激しかったのでThunderbolt3接続出来るこちらの商品を購入しました。 結果はとても快適な速度が出ますし発熱は全く気にならないレベルで動作します、筐体全体が分厚いアルミで出来ているので他製品と比べると重たいですが放熱は完璧だと思いました、USB 3.2 Gen 2規格は曖昧な部分があるらしくMacとは相性が悪いですね。 youtubeの情報ですがOWCはAppleなどの企業と関わって仕事をしている会社なので信頼がおけると思います。

OWC ENVOY PRO FXの2Tを購入して1ヶ月が経ちました。使用して全く問題ありません。速度も十分に早いです。ENVOY PROにFusion用の仮想環境を構築していますが、速度も早くトラブルも全くありません。使用中はほんのりと暖かくなりますが、内臓SSDよりは温度は低いです。iMac Proの内臓SSDとENVOY PROのDiskMarkの測定結果を載せます。

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.

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.

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
