(On a carpeted concrete floor.) Review: SSD is wonderful! - Ordered this for fast external storage, and it’s been excellent. Speed is the headline. When connected over Thunderbolt, transfers are noticeably faster than standard USB drives—large files move quickly, and it keeps up without slowing down mid-transfer. For things like video files or large projects, that makes a real difference. Build quality is another strong point. The drive feels solid and durable, not something you have to baby. It’s compact too, so it’s easy to keep in a bag without taking up much space. After using it across a few different systems, it’s been reliable—no disconnects or weird behavior, just consistent performance. One thing to keep in mind: to get the top speeds, you’ll need a Thunderbolt-compatible setup. It still works over USB-C, just not at the same peak performance. Compared to other external SSDs, this one stands out for speed and build quality, especially if you’re moving large files regularly. For the price, it’s a great value if you actually need that level of performance. It’s not just storage—it’s fast, dependable storage that keeps up with demanding use. 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. ## Features - Super-fast speeds up to 3000MB/s(1) read and 2500MB/s(1) write with Thunderbolt 3 (40Gbps), capable of moving 50GB in 1 minute or less - Dual-mode compatibility with both Thunderbolt 3 (40Gbps) and USB-C (10Gbps) - Ultra-rugged design with high-level IP68 dust/water resistance, 4000lb crush resistance, and 3m drop resistance (On a carpeted concrete floor.) - Cool aluminum core pulls heat away from the internal drive to help maintain super-fast transfer speeds - Pro-grade enclosure for premium strength you can feel - Drive Format: Mac ready (APFS) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BW6715SV | | Additional Features | Dust Resistant, Portable, Water Resistant | | Best Sellers Rank | #47 in External Solid State Drives | | Brand | SanDisk Professional | | Built-In Media | PRO-G40 SSD, Quick Start Guide, Thunderbolt 3 (40Gbps) Cable | | Cache Memory Installed Size | 4 | | Color | Information Not Available | | Compatible Devices | Mac, PC | | Connectivity Technology | Thunderbolt , USB | | Customer Reviews | 4.0 out of 5 stars 1,078 Reviews | | Data Transfer Rate | 3000 Megabytes Per Second | | Digital Storage Capacity | 4000 GB | | Enclosure Material | Information Not Available | | Form Factor | Portable | | Global Trade Identification Number | 00619659195991 | | Hard Disk Description | Solid State Drive | | Hard Disk Form Factor | 0.5 Inches | | Hard Disk Interface | USB 3.0 | | Hard-Drive Size | 4 TB | | Hardware Connectivity | Thunderbolt | | Installation Type | External Hard Drive | | Item Weight | 0.27 Pounds | | Manufacturer | Sandisk Technologies, Inc. | | Media Speed | 2500 | | Mfr Part Number | SDPS31H-004T-GBCND | | Model Name | SanDisk Professional PRO-G40 SSD | | Model Number | SDPS31H-004T-GBCND | | Number of Items | 1 | | Read Speed | 3000 Megabytes Per Second | | Special Feature | Dust Resistant, Portable, Water Resistant | | Specific Uses For Product | Business, Multimedia, Personal | | UPC | 619659195991 | | Unit Count | 1.0 Count | | Warranty Description | 5-year limited manufacturer warranty | ## Product Details - **Brand:** SanDisk Professional - **Color:** Information Not Available - **Compatible Devices:** Mac, PC - **Connectivity Technology:** Thunderbolt, USB - **Digital Storage Capacity:** 4000 GB - **Hard Disk Description:** Solid State Drive - **Hard Disk Form Factor:** 0.5 Inches - **Hard Disk Interface:** USB 3.0 - **Installation Type:** External Hard Drive - **Special Feature:** Dust Resistant, Portable, Water Resistant ## Images ![SANDISK Professional 4TB PRO-G40 SSD - Up to 3000MB/s, Thunderbolt 3 (40Gbps), USB-C (10Gbps), IP68 dust/Water Resistance, External Solid State Drive - SDPS31H-004T-GBCND - Image 1](https://m.media-amazon.com/images/I/713UKhxDZSL.jpg) ![SANDISK Professional 4TB PRO-G40 SSD - Up to 3000MB/s, Thunderbolt 3 (40Gbps), USB-C (10Gbps), IP68 dust/Water Resistance, External Solid State Drive - SDPS31H-004T-GBCND - Image 2](https://m.media-amazon.com/images/I/8166AOetb+L.jpg) ![SANDISK Professional 4TB PRO-G40 SSD - Up to 3000MB/s, Thunderbolt 3 (40Gbps), USB-C (10Gbps), IP68 dust/Water Resistance, External Solid State Drive - SDPS31H-004T-GBCND - Image 3](https://m.media-amazon.com/images/I/81NlqKV14xL.jpg) ![SANDISK Professional 4TB PRO-G40 SSD - Up to 3000MB/s, Thunderbolt 3 (40Gbps), USB-C (10Gbps), IP68 dust/Water Resistance, External Solid State Drive - SDPS31H-004T-GBCND - Image 4](https://m.media-amazon.com/images/I/91KkMXrOzVL.jpg) ![SANDISK Professional 4TB PRO-G40 SSD - Up to 3000MB/s, Thunderbolt 3 (40Gbps), USB-C (10Gbps), IP68 dust/Water Resistance, External Solid State Drive - SDPS31H-004T-GBCND - Image 5](https://m.media-amazon.com/images/I/81eqSM14AIL.jpg) ## Available Options This product comes in different **Size** options. ## 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: Unclear. I’ve ordered an iPhone Pro Max but cannot even find information about whether or not it will work at speed with Thunderbolt 4 cable. Apple only says that it is “compatible” while it mentions specifically other devices like MacBooks that would benefit with top transfer speeds up to 40GBps. **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: Need to back up 500gb of 2012 MacBook Pro; would this be a good choice to do so? (No lightning/usbc port)** A: It wouldn’t, no. I had no luck using it with a USB-C to USB-A cable, not adapter. I tried several brands/kinds, but none worked. If I recall, TB 1 and 2 don’t offer power output, so you’re out of luck there as well. Though, if you want to spend an unreasonable amount of money on this, plugging the drive into a TB3 or 4 dock and connecting that dock to the laptop using a TB3 ->TB2 adapter may work. ## Customer Reviews ### ⭐⭐⭐⭐⭐ SSD is wonderful! *by P***T on April 19, 2026* Ordered this for fast external storage, and it’s been excellent.

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. ## Frequently Bought Together - SanDisk Professional 4TB PRO-G40 SSD - Up to 3000MB/s, Thunderbolt 3 (40Gbps), USB-C (10Gbps), IP68 dust/Water Resistance, External Solid State Drive - SDPS31H-004T-GBCND - Cable Matters [Intel Certified] 40Gbps Thunderbolt 4 Cable 3.3ft with 8K Video and 240W Charging - 1m, Compatible with USB4, Thunderbolt 3 Cable and USB-C - Lacdo Hard Drive Carrying Case for SanDisk Professional PRO-G40 SSD 1TB 2TB 4TB USB-C External Solid State Drives EVA Shockproof Water Repellent Storage Travel Bag, Black+Gray --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/533823399-sandisk-professional-4tb-pro-g40-ssd-up-to-3000mb-s](https://www.desertcart.sk/products/533823399-sandisk-professional-4tb-pro-g40-ssd-up-to-3000mb-s) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-25*
