About this deal

The evaluation scheme for DAS units involves multiple workloads which are described in detail in the corresponding sections. 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. 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.

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. The milled aluminum and rubberized coating provide a sturdy home for the NAND module mounted inside the SanDisk Professional G-DRIVE SSD. While its upper surface feels like hard plastic, the edges and underside of the Pro-G40 SSD feature a soft-touch coating that enhances grip and provides a pleasing tactile sensation. However, that coating comes at the expense of collecting fluff. 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. But the same as that counterpart, SanDisk doesn’t provide a pouch or case to carry the drive and its cables, a niche that some third party will undoubtedly fill.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. 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. 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.

But we can say with some certainty that any attempt to open it would immediately invalidate the five-year limited warranty. 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. As it comes pre-formatted for Apple APFS, Windows PC owners will need to understand how to use the Management Console and volume management to reformat the drive to a file system that Windows will understand.While it will work with USB 2.0 and USB 3.0 (aka USB 3.1), to get the best transfer speeds from it requires a port with USB 3.2 Gen 2 10Gbit/s.

Prior to looking at the benchmark numbers, power consumption, and thermal solution effectiveness, a description of the testbed setup and evaluation methodology is provided. Testbed Setup and Evaluation MethodologyWhy 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. That you can buy two Crucial X8 for the price of a single SanDisk Professional SSD that isn’t any faster suggests that either Crucial is underselling its line or SanDisk has entirely lost the pricing plot. For those purchasing the G-DRIVE SSD for their Apple Mac, all they need to do is connect it to a recent Apple Mac computer, as the drive is pre-formatted with APFS. 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.

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. And for those wondering if this high pricing is Brexit related, it isn’t. The prices for this range in France are equally inflated, being €163.99,€264.99, €410.99 and €769.99.

The SanDisk Professional Pro-G40 SSD has a premium quality feel and its sturdy outer shell withstands flexing during heavy-handling. It also emerges unscathed after multiple drops onto a concrete surface. 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.
