Fantom Drives 4TB External SSD, 3D NAND Portable Solid State Drive, Thunderbolt 3 & 4 USB 3.2 Type-C, Fast & Reliable up to 3000MB/s, SSD Storage Drive, TB3X-3000N4TB

Once there's more than 1.5 TB on the Drive it slows to a trickle... Has nothing to do with thermal, but for some reason on multiple computers and different versions of OS it slows to 50mbps write speed.

UPDATE I reformatted the drive as APFS encrypted and saw ~4.8% drop in write speed to 2439-2446 MB/s. Read stayed in the low 2500s. Still blazing and now more secure. I also picked up a Maxonar Thunderbolt 4 half-meter cable for something a little longer. The included cable is labeled as Thunderbolt 3. There is no noticeable speed difference between them. ORIGINAL REVIEW I got the 4TB non-TLC with the 3k speed and it's delivering about 3x the write and 4x the read speed of my Samsung T7 of the same capacity, which is basically a USB 3.2 speed drive, not Thunderbolt. This is about 4 ounces heavier than the T7, with a solid feeling metal case vs. the T7's rubberized case,. It's a thicc little drive that's a smidger taller, wider, and thicker than the T7. I tested it against the internal drive in a 2 month old MacBook Pro M3 (16") and a 3-year-old desktop PC gaming rig. While it got blown out of the water by the MBP's internal drive which was 2-3x faster in each measure, it was 80% as fast on write and almost double on read compared to the desktop with NVME. When you see people claiming they sped up an old, slow machine by using some variant of this as a boot drive, I'd bet they're telling the truth. It's fast enough to power a number of low-to-mid-range laptops or even desktops if they have USB 4 or Thunderbolt 4. Obviously I just picked this up and I'm in a honeymoon phase. We'll have to see how durable both the drive and its speeds are. But I am predicting I am not going to have storage anxiety with my MBP for a while.

I recently acquired this CD player to complement my Mac Desktop. I have rated it with four stars due to a specific issue encountered during the setup process. Regrettably, the instruction manual lacks essential information regarding the default read-only formatting of the HD upon unboxing. The inability to add new files to the HD until it is reformatted to "read and write" posed a considerable challenge, necessitating an additional hour of troubleshooting. The resolution of this issue could have been expedited had the instruction manual included a brief clarification about the default formatting state and provided guidance on transitioning it to "read and write" functionality. Such an enhancement to the documentation would have significantly contributed to a more streamlined and user-friendly experience.

No idea if this is TLC, QLC or SLC, but it's freakin fast! fastest drive i've ever tested actually. I own the sandisk extremes that reads at about 1055mb/s and the OWC that reads at an amazingly fast 2700mb/s and this beast that leaves them all in the dust. Not sure why this is priced lower than the slower TLC version (picked up at $379!) but it's better and a newer model. Highly recommend and get it before they bump the price up.

I have attached read and write speeds on a Macbook M2 Pro. Not quite up to 3000 but fairly close. It's larger than I expected but in line with drives of the size and speed. Fast shipping.
