Review: High-Speed Performance with Notable Reliability Concerns - I recently purchased the SanDisk Professional 4TB PRO-G40 SSD, enticed by its impressive specifications and rugged design. Initially, the drive delivered exceptional performance, boasting read speeds up to 3000MB/s and write speeds up to 2500MB/s when connected via Thunderbolt 3 . The aluminum core and IP68 rating for dust and water resistance gave me confidence in its durability, making it suitable for on-the-go professionals. However, after a few weeks of use, I encountered several reliability issues. The drive began to intermittently disconnect, requiring multiple reconnections before it would appear in Finder on my MacBook Pro. Additionally, I experienced problems with Spotlight indexing and occasional system freezes upon ejecting the drive . Despite these challenges, the drive's speed and ruggedness remain appealing. If you're considering this SSD, be aware of potential compatibility and reliability issues, especially with macOS systems. It's advisable to ensure your system's USB-C ports provide sufficient power and to use high-quality cables to minimize connection problems.
Review: High speed in a small package - I added this SSD to my M4 Mac mini to give it some extra storage space for LLMs and photos. I love the small size of this drive as well as the super high transfer speed of Thunderbolt. It's a great combo that's good for video or photo editing, data backups, or just general storage. My Mac recognized this out of the box, so I didn't even need to format it. If you're looking for some extra space and your computer supports Thunderbolt, take a look at this drive.

## Questions & Answers

**Q: What is the significance of 40gbps if the drive can only transfer at 2700mb/s? isn't only around 7% of 40gbps?**
A: Drive transfer is 2700 MB/s (mega bytes/s), since 1 byte=8 bits so 2700 x 8= 21600 mb/s, which is more than 50% of 40 Gb/s Thunderbolt

**Q: Will it work with the new iPhone 15 Pro Max for recording video direct?**
A: I purchased this to use with new iPhone 15 Pro for ProRes record. But it does not even get recognize from iPhone. I do not recommend to buy this if you are into using with iPhone.

**Q: imac 2017 model 10.13.6 - nearly to of memory - will this work on my older iMac?  Connects ok to the ports (no idea what they're called)...thanks!**
A: It’s my understanding that Apple’s Thunderbolt ports are backward compatible. So it should work. But you won’t get the full speed this drive is capable of delivering. This is a Thunderbolt 3 design.

**Q: Can this work (i'm concern over power needs and heat) with the iPhone 15 Pro Max for 4K 60 ProRes video?**
A: I tried mine (same combo) and it only detected as a thunderbolt device. I don’t know that it will work at all. (I’m planning on trying a different cable, I’ll follow up if it’s good news.)

### ⭐ DO NOT BUY: Constantly loses connection, no customer support
*by A***T on February 13, 2024*

I bought this to use as a backup for my computer, as well as for music production. The thing is great when it works - it’s hella fast, and so freaking tiny. Unfortunately, the device is constantly, spontaneously “improperly ejected” from my computer. I get constant notifications/warnings. I’m using the provided cable. It should just work. It’s less than a month old. I reached out to customer support a week ago and haven’t heard anything yet - not even a “thanks for reaching out” email. It might be worth it to check out their competition. This thing is too expensive for this kind of performance and (lack of) customer service, and you’re probably buying this because you need something reliable that actually does the thing it says it should do. Update: It’s been two months and I still am having constant issues with the drive spontaneously disconnecting. I still have not heard back from customer service after reaching out to the emails provided on their website. I also just wanted to say that I’ve had the overheating issues others have mentioned when it does work. Sometimes it seems to decide to just stop working because it gets so hot (which is yet another way I lose work thanks to this thing). I’m so upset that I spent so much money on this and have lost hours/days of work because of the problems this thing has. I’m in the process of trying to jerry-rig a solution - I just spent ~$50 on different kinds of tapes and cables to try to see if that will solve the problems. I cannot caution against this thing enough. Save yourself the headaches and heartaches of losing valuable data and go with the Samsung version. It may cost more up front, but you’ll be saving yourself in more ways than you know. Update 4 months later: Still no word from “customer support”. None of the cables (or tape) I purchased to try instead of the included one solves the issue, which is how I know without a shadow of doubt it’s an issue with this joke of a product and not my computer. This has been the worst purchase I’ve made in probably a decade. I’m going to end up buying the Samsung one, so I’m just out $400 because I made the mistake of not purchasing this with a credit card that might have offered more purchase protection. I still cannot caution against this thing enough. Do not make my mistake. Spend your hard-earned money on something that’s actually worth what you’re spending. Update 1.5years later: Just wanted to come back and state again how much I hate this hard drive after looking at other hard drives again and getting super sad and annoyed that I ever bought this one to begin with. It remains probably the worst purchase I've made for as long as I can remember. Please do not make the same mistake me and others made. It's not a cheap one to make. I literally will never purchase another sandisk product again because of this experience.
