SanDisk Professional: External Pro-G40 SSD is Fast and Expensive

#image_title

Western Digital is expanding its lineup of SanDisk Professional-branded external SSDs. The new Pro-G40 SSD offers 1 TB or 2 TB of storage in a dust- and water-protected aluminum case, as well as high transfer rates of up to 2,700 MB/s via Thunderbolt. However, the prices are quite a bit higher.

Thunderbolt 3 or USB 3.2
Designed as a new top model in the field of external storage solutions for professional users, the SanDisk Pro-G40 SSD is compatible with two interfaces with different performances: Transfer rates of up to 2,700 MB/s read and 1,900 MB/s write are promised via Thunderbolt 3, limited here by the built-in NVMe SSD. If the host system only supports USB 3.2 Gen 2 with 10 Gbit/s, a maximum of 1,050 MB/s read and 1,000 MB/s write should be possible.

The 111 × 58 × 12 mm (L × W × H) casing contains unspecified NAND flash with usable storage capacities of 1 TB or 2 TB. The two variants weigh 121 grams and 122 grams respectively; the additional memory chips in the 2 TB model also weigh a bit. A Thunderbolt 3 cable with a USB-C connector is included.

Protection against dust, water, and drops
The manufacturer describes the Pro-G40 as extremely robust and advertises a “drop resistance from up to three meters”, although a footnote indicates that a drop onto carpet is meant. The IP68 certification is more tangible and means, according to binding guidelines, that the SSD is dust-proof and also waterproof, at least up to a diving depth of one meter.

The casing material is supposed to ensure that high transfer rates are possible even during longer use since aluminum is known to dissipate heat much better than plastic.

For creative professionals who, for example, want to edit 4K videos in real-time and directly from the data carrier, or others with a desire for fast data transfers, the portable SSD is said to be ideal. However, the price is steep: the recommended retail price of the Pro-G40 with 1 TB is 471 euros, and the 2 TB model costs a whopping 740 euros.

The editors had initially thought the price information to be a mistake, since the US prices are around 300 USD and 450 USD, although this is without taxes. However, we asked the manufacturer for confirmation and the following statement:

“The pricing of our product lines varies worldwide due to various factors. These include customs duties, taxes, fees, and exchange rates. After launch, MSRPs may also change according to market conditions.”
