OWC Envoy Pro Mini 1TB (10Gb/s) SSD, Up to 940 MB/s Speed, Portable Flash Drive with USB-C and USB-A, Compatible with Mac, PC, Xbox, PS5, Professional Stick for Gaming, Storage, and Backup

This OWC Envoy Pro FX 2TB Portable NVMe M.2 SSD [ASIN B08YMR64RT] design is unusual and almost unique— it can't be overstated. Having the current interface Thunderbolt speed and (TB/ USB-C) connector for a Mac Studio (M1 Max, 2022) running macOS 12.3.1 ("Monterey"), OR being also able to alternatively use USB 3.0's full speed (5Gbps) with a Mac mini (Late 2012) running macOS 10.13.6 ("High Sierra"), OR alternatively use USB 2 (480Mbps) with a 17" MacBook Pro (Mid 2010) running macOS 10.13.6 ("High Sierra"), OR USB 1 (12Mbps) on legacy G4 Macs, allows me to have one single 2TB fast, rugged, portable drive that I can use as my primary user account folder!Now, I don't have to waste time syncing files on various Macs, nor duplicating directory structure changes to enable syncing. The latter is especially significant. No matter how diligent I try to be, there are always spontaneous directory structure changes I make, which I don't have time or access to duplicate on other Macs—then syncing becomes a nightmare.Perforance of this OWC Envoy Pro FX 2TB Portable NVMe M.2 SSD is excellent. Using ChronoSync 10, I created a 1.61TB 1.85 million file bootable clone of a Mac mini (Late 2012) internal SSD via USB 3.0 (5Gbps) in 3 hours 33 minutes 20 seconds, with full verification. ChronoSync scans the source, copies the source file, writes the target file, then fully reads the target written file, compares with the source file, and then writes a detailed log file entry. The NET aggregate throughput achieved was 132MBps (1.03Gbps) (3 to 10 times faster than similar ChronoSync cloning operations to a WD 12TB My Book HDD). As a software and hardware engineer, I can't rigorously compute the isolated write speed without more research, but I suspect it is roughly at least double the above net aggregate measured.This OWC Envoy Pro FX 2TB Portable NVMe M.2 SSD is physically built like an armored tank—I seriously think I could run over it (slowly) with a large SUV without fracturing the solid aluminum case. (Do NOT try this at home! ;-)The $549 I paid for this OWC Envoy Pro FX 2TB Portable NVMe M.2 SSD is small compared with the value received. Being able to buy new Macs with base SSD capacity already has saved me the OWC's price, AND I don't have to wait for a BTO (built to order) model to be queued. A stock base model Mac Studio 512GB SSD was immediately available. I would have had to wait 4 – 10 weeks, and spend $600 (for 2TB SSD) to $2,400 (for 8TB) more had the OWC Envoy Pro FX 2TB Portable NVMe M.2 SSD not been available. (As you may have noticed, Macs are generally useful for a long time. 10 – 20 years isn't extraordinary—for a Mac, that is. My 2003 Xserve G4 is still hosting Internet services.) Now that most new Macs generally do not have user upgradable drives, nor RAM, I would tend to max both. So $549 OWC likely saved me $2,400.I would definitely buy this OWC Envoy Pro FX 2TB Portable NVMe M.2 SSD again, and recommend others purchase as well.

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.

A very well made external Hard drive. Fast, I got the 2tb version to back up my system in case of a crash or problem. It is well worth the cost believe me. And takes up hardly any room. Other World Computer always has great products.

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.

This is a well made SSD with great performance.I contacted OWC tech support to see if there was a way for me to get information about the drive itself (hardware errors, firmware version, etc.). They directed me to their softRAID management software. That costs anywhere from $49.99 up to $249.99. While there is a 14 day free trial for the software, OWC should provide a free basic tool that allows SSD users to do basic management tasks on their SSD. Directing a user to a tool that costs up to 50% of the original cost of the SSD is ridiculous.
