I have a machine with a mix of sabrent and intel 660s, and this drive convinced me that I can't get rid of the intels fast enough.
HUGE! 4Tb is awesome for a single NVMe (though apparently there is an 8Tb option as well, but I'm sure that costs more than the PC I'm putting it in.
FAST! You can go faster if you get PCIe 4.0 (and since the price difference isn't even a 5% bump for 50% faster you should buy the Q4 instead if your system can fully utilize it) but on PCI3 3.0 device I'm satisfied. For reference, I moved 1.5 TB off a 2 Tb SSD onto this 4Tb SSD in under an hour including opening the computer twice.
Pricy! However, this QLC (4 bits per slot) brings the price down more than a $100 from the Rocket, without compromising speed.
In short, if you need a huge fast drive buy this. If it needs to be even faster buy a smaller sabrent. If slow is fine and portability doesn't matter you can't beat spinning discs for raw capability, but if speed or portability are needed with the capacity this is the drive for you.
