SanDisk Professional PROJECT Reviews

Fast & dependable

I am a graphic designer, and I use this drive as the Time Machine for my desktop iMac. It arrived preformatted for a Mac, so installation was easy and quick. Although I have read that this model emits a slight sound, I can't hear anything, although it is only 18" away. Interestingly, the white LED "on" light can be toggled to off, low, and high -- something that might be useful to some users. Because it's my Time Machine device, speed isn't my highest priority for it, but I'll note that it does perform its backups much quicker than its predecessor. My only quibble with it is something that might be a function of my computer, not this drive. It's one of 3 external drives that I use, and the only one that doesn't automatically reboot itself if I have to turn off my computer. Instead, I have to use its password to reinstall it each time. My neighborhood is prone to power outages, so this is a nuisance. I'd love to hear of a solution. Meanwhile, I'll keep the password handy.

This drive did very light duty as a 2x/week backup Time Machine for my Mac. Died after 15 months. Would not recommend.

OK, at one point you're talking about 40Gb/s, and then 250 Mb/s r/w speeds. I don't get how they reconcile?
Asked by: Roderick
Thunderbolts 3 and 4 have a 40Gbps pipe. You can daisy chain up to 5 additional devices and all those devices use that 40Gbps pipe. The Pro-blade also gets 1000MB/s, so it uses more of that performance too. Interface vs disk speed is tricky stuff!

Why does the Pro-Blade slot on the G-Drive ...

Why does the Pro-Blade slot on the G-Drive Project transfers only 1000MB/S while the Pro-Blade Station reads/writes at 3000MB/S?
Asked by: Brett
The internal connection to the problade is at usb 3 speeds (its probably a cheaper and creates less heat), where as the Problade dock is a deadicated dock for the blades with a faster thunderbolt interface/pipeline. Its a shame, but 1000Mbs is still quite fast and good enough most of the time.
