The SD will say take 20 to 30 minutes to download onto the Mac's 2TB SSD but then only a minute or two to store on each G40.So far only issue is apparently some dead areas. Explanined: i save all data (foto images & movie 'footage' in duplicate, & try to load drive within 100 to 200 GBs of 4TB limit. There is discrepacy of 8 to 9 GB between the identical files on one or two drive pairs.

Am aware this is probably far far less than average usage.

Right now, I just got off the phone with SanDisk/Western Digital technical support. It was a very sad and frustrating conversation with technical support. I just received my second SSD drive from SanDisk only to be told that the drive had some issues right out of the box. I was offered a 20% discount off the Western Digital price of the same SanDisk professional G 40 SSD drive at their recommended retail price of $450, or I could return the drive to Western Digital and they would replace it.

I have always read good reviews and stories of SanDisk products, but the reality is far from the actual experience.Based on my experience with SanDisk products and their customer service I will not be buying another SanDisk or Western Digital product. I would also recommend anyone reading this review to not by SanDisk or Western Digital products.

I've have this SSD with 4 TB capacity for about a month with no issues running Time Machine from a brand new 14" Apple MacBook Pro with M3 Max, 96 MB memory, running macOS Sequoia 15 (+). After migrating via LAN from my 10 year old MacBook Pro just under 1 TB of date, I backed up the data via Time Machine to this SSD -- which took under 4 minutes -- maybe 3 minutes 30 seconds +/- some seconds. The apple.support technician who had helped me with the migration of data from the old to new laptop stated he never seen a drive consume 1 TB so quickly the data via Time Machine. My eyes were huge looking at the time remaining quickly counting down. It is REALLY fast, ran warm but not hot at the end of this transfer.

I'm looking to purchase a 20 B RAID 2 system; but, in the meantime, I'm quite satisfied with this SSD, which I will eventully use the one for processing very large photo files via Capture One Pro; the other as a Time Machine backup to the processing when traveling. SO, again, I'm purchasing another -- the speed and price makes a second a no brainer to me. I hope its durability lasts for at least a few years -- it sure seems so. Oh, to add, now having disciplined myself to not repeat, I have disconnected it trice without first ejecting it -- though with no issues -- definitely not a good practice!.

The drive arrived in perfect condition and worked great. I do want to mention an important variable in its operation for any person thinking of buying such a high performance drive: sometimes when I plug it in using the supplied Thunderbolt 3 cable, or using an Apple Thunderbolt 4 cable, it will not show up on my MacBook Pro M2 Max. My best guess is that if too many PCIe lanes are occupied by other tasks, including other drives, it will not show up, not even in Disk Utility. This makes me nervous because I then do not have the option of ejecting the drive before disconnecting it. On the other hand, if I disconnect other drives first, the PRO-G40 will show up every time. Do not risk any damage to your PRO-G40. If possible, always connect your PRO-G40 before ... MoreThe drive arrived in perfect condition and worked great.

The SanDisk Pro-G40 Thunderbolt SSD is an external drive for those who need uncompromising performance from their storage devices. Connected to my M2 MacBook Air, performance is simply astonishing and up to 50% faster than the internal SSD that my Mac came equipped with from Apple! Thunderbolt enables PCIe performance so it shouldn't be a surprise that the drive can hit 2700 MB/s reads. What I love about the PRO-G40 is that it also offers regular USB-C 3.2 backwards compatibility for use with devices that don't have open Thunderbolt ports. It does come with a short TB3 cable in the box which is a plus.As a byproduct of having internal NVMe level performance, the SanDisk Professional drive is a great choice for those who work on UHD+ video projects. My previous ... MoreThe SanDisk Pro-G40 Thunderbolt SSD is an external drive for those who need uncompromising performance from their storage devices.

What I love about the PRO-G40 is that it also offers regular USB-C 3.2 backwards compatibility for use with devices that don't have open Thunderbolt ports. It does come with a short TB3 cable in the box which is a plus.As a byproduct of having internal NVMe level performance, the SanDisk Professional drive is a great choice for those who work on UHD+ video projects. My previous external SSD was a USB-C 3.2 model which seemed pretty fast at 900 MB/s R/W performance when I got it about 2 years ago. However, when working on video projects I often found myself copying the input files to my internal storage when possible, so I was working off my internal drive with its higher performance and maximizing the speeds when it came time to export the finished video to my larger external SSD. With the PRO-G40, this extra step is eliminated as the drive is both larger and faster than my internal storage. Especially when stitching dozens of small clips, this drive can easily handle anything you throw at it.The PRO-G40 is also built like an absolute tank and can easily survive being tossed in a camera bag for an outdoor trip. The case seems to offer substantial heat dissipation capability as well. I say this because it gets warm quite quickly and doesn't seem to drop performance by much when hitting it with lots of writes.Finally, the drive comes formatted to work with Macs for Time Machine and is thus incompatible with non Apple devices out of the box. I've left mine formatted as APFS as I haven't used Time Machine for a few years, but I may eventually reformat for compatibility with my Android phone and Windows PCs. Just something to keep in mind if you plan to use this drive with a Windows computer.

Sandisk's latest Pro G40 External SSD brings Thunderbolt 3 speed along with durability and portability.With external storages becoming smaller, lighter, and more reliable, what distinguishes each is their speed and features. Sandisk's external SSD supports Thunderbolt 3's technology and allows for faster transfer speeds through its USB 3.2 Gen 2 interface. Having an SSD over a standard HDD gives you faster read speeds and portability (among other features), but having a drive that supports Thunderbolt 3 provides quicker speeds when using it with a computer or device that also supports Thunderbolt 3. When not using it with a device that supports Thunderbolt 3, the USB 3.2 Gen 2 speeds will also keep read and write transfer speeds quick.In one simple test I ran ... MoreSandisk's latest Pro G40 External SSD brings Thunderbolt 3 speed along with durability and portability.With external storages becoming smaller, lighter, and more reliable, what distinguishes each is their speed and features.

When not using it with a device that supports Thunderbolt 3, the USB 3.2 Gen 2 speeds will also keep read and write transfer speeds quick.In one simple test I ran using my Mac's Thunderbolt 3 interface, I copied 10 half gig video files and it took less than 3 seconds for the copy to complete. When testing the transfer speed with more files (2,500 files of pictures and videos), it was able to transfer them in 11 seconds! Since the Pro G40 is formatted in APFS (for use in Mac computers), it cannot be used simultaneously on Windows computers. This is not a defect but how all drives operate (needing a file system, in this case APFS). If you prefer to use the drive with a Windows computer, it would need to be reformatted and can be done so using Windows’ built in Disk Management utility. Keep in mind, if you reformat the drive, all data on it will be deleted and it is recommended for the data to be copied onto another device temporarily.In addition to the super quick transfer speeds, the rubber type enclosure (on the sides and back of the enclosure) of the SSD offers durability being able to survive drops of up to almost 10 feet as well as having a crush resistance of two tons (4,000 lbs)! While I don’t expect to run over it with my car, it is nice knowing that if I dropped it and it gets run over, my data will survive. Along with drop and crush protection, the G40 is also water resistant up to 1.5 meters (a little under 5 feet) and dust resistant (IP68 rating).As for the cons, I’m a little disappointed it doesn't include the latest iteration of Thunderbolt, which is 4. This would help for future proofing, competition against similar drives, and the speed that Thunderbolt 4 adds. The Sandisk Pro G40 2TB version, unlike the 1TB version, did not get too hot in my testing and can say I didn’t experience any performance drops while using it throughout my day.Overall, the Sandisk Pro G40 is a great external drive for long term or short term storage of your data. It is wickedly fast and is great when moving over lots of files or when you’re simply attempting to load up files (such as when video editing or loading up a stored video game). I would recommend this to anyone looking to find a small, durable, and quick external SSD drive for storing and backing up their data.
