SanDisk Professional 2TB PRO-G40 SSD external Drive, Portable SSD, up to 3000 MB/s, Solid State Drive, Thunderbolt 3 (40Gbps), USB-C (10Gbps), Ultra-rugged IP68 dust/water resistance. Formatted exFAT

This first thing to know about the Pro G40 is to discard the included cable and use a true Thunderbolt 4 cable if you are using a Mac M1 or above. The second thing is to ignore the results from other reviewers who didn't use a fast cable to run their tests. See the results I obtained with a TB4 cable and a Mac Mini M2Pro in the included graphic. It actually exceeded the 3000MB/s rating and also properly identified the internal WD-Black SSD that SanDisk is using (lower left corner). Initially I used the included cable as did another reviewer, but those results didn't quite make 1000MB in sequential reads. Something had to be wrong. I don't know why such a feeble cable is included with this very fast drive...but that's the reality. For readers of this review I held my breath and dropped the G40 from waist high first on carpet, then on a floor protector as one uses under an office chair, and finally on a very hard floor. The performance before and after was identical for practical purposes. The accompanying performance chart numbers are the results after the 3 drops. This drive puts my SanDisk Extreme Pro 4TB and Costco SanDisk Extreme Go 2TB in the rear view mirror, each performing at roughly a third of the speed of the G40. And for those of you who are curious, the Costco SanDisk Extreme Go is a slightly slower performer compared to the SanDisk Extreme Pro. I hope this review makes clear how to obtain the best performance of this very fast and rugged portable drive. I tested 5 TB4 cables each under $20 from Amazon and found they all performed identically, so take your pick, it's a good investment. Otherwise it makes no sense to buy this expensive drive. Highly recommended.

Rapide bien

Il mio iMac 27 del 2019 5K con Fusion Drive ha ripreso vita grazie a questo prodotto: Utilizzato come disco di avvio, nonché principale (Grazie ai 2 TB), il computer è diventato una scheggia. Ero un pò dubbioso visto il prezzo, ma è anche vero che non avevo voglia di cambiare dispositivo, tenendo presente la qualità dello schermo e della bontà del dispositivo, tipo di storage a parte. Consiglio questo prodotto per chi, come me, ha un computer altamente valido, ma con un hard disk meccanico che fa da tappo, e vuole aggiornarlo senza troppe difficoltà o rischi (dovuti ad esempio alla sostituzione interna dell'Hard Disk, che su Mac è particolarmente complicata e rischiosa), o a chi ha bisogno di uno storage importante ma veloce quanto un SSD interno e molto resistente Davvero un ottimo prodotto, con prezzo elevato, ma giusto per la qualità e prestazioni che offre.

Minimal packaging. Light and compact. Ready to use on a MacBook. What’s not to love?
