Why they didn’t use exFAT and a utility that runs on both platforms to reformat the drive for both groups is a mystery. Because that’s normally what Western Digital does, the overarching business that owns the SanDisk brand.
The milled aluminum and rubberized coating provide a sturdy home for the NAND module mounted inside the SanDisk Professional G-DRIVE SSD. Neither the name of the University of California, Berkeley nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission. The evaluation routine for direct-attached storage devices – portable SSDs, storage bridges (including RAID enclosures), and memory cards – all utilize the same testbed and have similar workloads with slight tweaks based on the end market for the product. Our testbeds have kept pace with the introduction of new external interfaces - Thunderbolt 2, Thunderbolt 3, and USB 3.2 Gen 2 via Type-C. In mid-2014, we prepared a custom desktop based on Haswell, which was then upgraded to Skylake in early 2016. A botched Thunderbolt 3 firmware upgrade on the Skylake machine meant that we had to shift to the Hades Canyon NUC starting in early 2019. This year, we have adopted the Quartz Canyon NUC (essentially, the Xeon / ECC version of the Ghost Canyon NUC) along with build components from ADATA Industrial - 2x 16GB DDR4-3200 ECC SODIMMs and a PCIe 3.0 x4 NVMe SSD - the IM2P33E8 1TB. The G-Drive SSD comes with none of these, regrettably. We can only conclude that those who designed the G-Drive SSD assumed that it would be mostly Apple macOS users purchasing this drive, and they have Time Machine and don’t need any other tools.
The specifications of the testbed are summarized in the table below: AnandTech DAS Testbed Configuration
Cool Aluminum Core: The PRO-G40 utilizes an aluminum core design that helps effectively draw heat away from the SSD controller and NAND flash memory while remaining cool to the touch and preventing throttling from heat saturation. The SanDisk PRO-G40 nails the storage trifecta creative pros need – speed, durability, and lots of space. This external SSD rips through transfers with blistering 3000MB/s bandwidth. The IP68 rating shakes off dust and even an accidental dunk in water. Plus, you get a massive 4TB to save all your projects. Therefore, for those with USB 3.0 (USB 3.2 Gen 1) ports, there is little point in purchasing this drive over cheaper options because you will never see its actual performance. In addition, I found that the 200 files from the Nikon Z7 II, which take up 9.74GB, transferred from the MacBook Air's desktop to the drive in approximately 5 seconds. Reversing the transfer direction took a similar amount of time. It means you’re not kept waiting around for your images to shift from one place to another.
A high-quality external SSD
We devote hundreds of hours of rigorous testing to help make sure your drive is worthy of your best work — and so you know your precious files are in good hands. s and 2500MB/s Read/Write Speeds: The PRO-G40 hits remarkable speeds up 3000MB/s read and 2500MB/s write over its Thunderbolt 3 interface. This bandwidth rips through transfers of 8K footage, giant photo libraries, or any media files you need to store or move. Both drives support S.M.A.R.T passthrough. X6 does not indicate TRIM as an available feature. However, we were able to activate TRIM in Windows on NTFS volumes in both drives. Temperature monitoring and obtaining health status (in terms of TBW) are simple for both drives. Microsoft Windows-using customers will need the technical knowledge and confidence to use the Windows management console to delete the existing partition and create a new NTFS or exFAT volume. Given the IP67 rating, it should handle the odd splash of water, being dumped in the dust and, with 2000lb of crush resistance, accidentally driven over by a family car.
Get fast NVMe™ solid state performance featuring 1050MB/s 2 read and 1000MB/s 2 write speeds in a portable, high-capacity drive that’s perfect for creating amazing content or capturing incredible footage. When connected to a PC using USB 3.2 Gen 2 ports, our speeds topped out at around 1,050MB/s reads with 1,000 MB/s writes on CrystalDiskMark 8.0.4, irrespective of USB-A or USB-C. The less optimistic AJA System test presented 881MB/s reads and 871MB/s writes using a 16GB test file. Included in the box are two 50cm cables, one each for USB-C and USB-A connections, allowing it to be connected to most computers that support USB. Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met:The port type is critical because USB 3.2 Gen 1 only offers 5Gbit/s of bandwidth, which equates to roughly 500MB/s, or the same speed as SATA SSDs can achieve. For those that own an Apple Mac, just connect the drive and then use it to manually copy files or configure it for Time Machine use. Probably the best aspect of this design is the available capacity, as many of the other SanDisk Professional SSDs are capped at 2TB, where 4TB of storage is available. Up to three-meter drop protection and IP65 water and dust resistance 5 mean this durable drive can take a beating. Capacity: With a spacious 4TB capacity, you can stuff this speedy external SSD full of all your photos, videos, audio recordings, game captures, and important documents.
Where this drive is better than the more expensive PRO-G40 is that it at least comes with both the USB cables most customers will need, and they are also a decent length. One curiosity is that the drive can supposedly handle being dropped 3 metres, but in the fine print, that’s onto concrete covered in carpet. The carpet requirement seems to be something of an odd detail, as the world wasn’t fully carpeted when we looked last. One area it does shine is that the NVMe inside has the capability for 256-bit AES-XTS hardware encryption, enabling the contents of the drive to be secured effectively.USB-C Connectivity: The PRO-G40 plays nice with both Thunderbolt 3 and USB Type-C ports. So you can experience great performance whether connecting to your MacBook Pro or an iPad Pro.
