Review: 🔥 Blazing Fast, Ultra-Compact, and Totally Worth It! - I absolutely loved my purchase! Exceeded my expectations from the very first use. The storage capacity of 1TB is perfect for anyone who needs extra space for large files, backups, photos, and videos without constantly worrying about running out of room. The performance is outstanding. File transfers take just seconds and, even under heavy workloads, the noise level is non-existent — completely silent, which I really appreciate. Another big plus is the compatibility. It worked flawlessly with my devices using USB-C, with no setup or additional software required. Just plug and play. The design truly stands out. It’s very small, exactly as shown in the photo, making it extremely portable and easy to carry in a bag or backpack. The fit in my hand feels great and gives a strong sense of durability and premium quality. Considering the speed, portability, build quality, and brand reliability, this SSD offers excellent value for money. It’s fast, compact, durable, and incredibly efficient. I highly recommend it to anyone looking for a powerful external SSD that delivers performance and convenience in a small package. An excellent choice! 🚀💯 Review: Excellent storage - I got this to hold my music library for my home server. I have been using it for about a month now and I liked it enough that I bought a second one. Transfers move quickly enough that loading the library over was not something I had to sit and wait on. It stays connected without dropping or needing to be reseated. The drive is small enough to sit next to the server without taking up any real space and it doesn't get warm to the touch. The rubberized body feels solid and the carabiner loop is there if you want to clip it to something, though mine just stays put. I didn't bother with the included software. Both of them have been running without a hiccup and I have no complaints. ## Features - Get NVMe solid state performance with up to 1050MB/s read and 1000MB/s write speeds in a portable, high-capacity drive(1) (Based on internal testing; performance may be lower depending on host device & other factors. 1MB=1,000,000 bytes.) - Up to 3-meter drop protection and IP65 water and dust resistance mean this tough drive can take a beating(3) (Previously rated for 2-meter drop protection and IP55 rating. Now qualified for the higher, stated specs.) - Use the handy carabiner loop to secure it to your belt loop or backpack for extra peace of mind. - Help keep private content private with the included password protection featuring 256‐bit AES hardware encryption.(3) - Easily manage files and automatically free up space with the SanDisk Memory Zone app.(5) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C59FBGG1 | | Additional Features | Portable | | Best Sellers Rank | #1 in External Solid State Drives | | Brand | Sandisk | | Built-In Media | Extreme Portable SSD, USB Type-C to C cable, USB Type-C to Type-A adapter | | Cache Memory Installed Size | 4 TB | | Color | Montery | | Compatible Devices | Desktop, Laptop, Tablet | | Connectivity Technology | USB | | Customer Reviews | 4.6 out of 5 stars 91,464 Reviews | | Data Transfer Rate | 1050 megabytes_per_second | | Digital Storage Capacity | 4 TB | | Enclosure Material | Nand Flash | | Form Factor | Portable | | Global Trade Identification Number | 00619659205027 | | Hard Disk Description | Solid State Drive | | Hard Disk Form Factor | 2.5 inches | | Hard Disk Interface | USB 3.2 | | Hard-Drive Size | 4 TB | | Hardware Connectivity | USB 3.2 Gen 2 | | Installation Type | Not Specified | | Item Weight | 1.76 ounces | | Manufacturer | Sandisk Technologies, Inc. | | Media Speed | 1000 megabits_per_second | | Mfr Part Number | SDSSDE61-4T00-G25M | | Model Name | SanDisk Extreme Portable SSD | | Model Number | SDSSDE61-4T00-G25M | | Number of Items | 1 | | Read Speed | 1050 megabytes_per_second | | Special Feature | Portable | | Specific Uses For Product | Personal, Business | | UPC | 619659205027 | | Warranty Description | 5-year limited manufacturer warranty | ## Product Details - **Brand:** Sandisk - **Color:** Montery - **Compatible Devices:** Desktop, Laptop, Tablet - **Connectivity Technology:** USB - **Digital Storage Capacity:** 4 TB - **Hard Disk Description:** Solid State Drive - **Hard Disk Form Factor:** 2.5 inches - **Hard Disk Interface:** USB 3.2 - **Installation Type:** Not Specified - **Special Feature:** Portable ## Images ![SANDISK 4TB Extreme Portable SSD (Old Model) - Up to 1050MB/s, USB-C, USB 3.2 Gen 2, IP65 Water and dust Resistance, Updated Firmware, Monterey - External Solid State Drive - SDSSDE61-4T00-G25M - Image 1](https://m.media-amazon.com/images/I/711-n+US0bL.jpg) ![SANDISK 4TB Extreme Portable SSD (Old Model) - Up to 1050MB/s, USB-C, USB 3.2 Gen 2, IP65 Water and dust Resistance, Updated Firmware, Monterey - External Solid State Drive - SDSSDE61-4T00-G25M - Image 2](https://m.media-amazon.com/images/I/912RwG2hN0L.jpg) ![SANDISK 4TB Extreme Portable SSD (Old Model) - Up to 1050MB/s, USB-C, USB 3.2 Gen 2, IP65 Water and dust Resistance, Updated Firmware, Monterey - External Solid State Drive - SDSSDE61-4T00-G25M - Image 3](https://m.media-amazon.com/images/I/81na9xbg9cL.jpg) ![SANDISK 4TB Extreme Portable SSD (Old Model) - Up to 1050MB/s, USB-C, USB 3.2 Gen 2, IP65 Water and dust Resistance, Updated Firmware, Monterey - External Solid State Drive - SDSSDE61-4T00-G25M - Image 4](https://m.media-amazon.com/images/I/91dnM5zzSAL.jpg) ![SANDISK 4TB Extreme Portable SSD (Old Model) - Up to 1050MB/s, USB-C, USB 3.2 Gen 2, IP65 Water and dust Resistance, Updated Firmware, Monterey - External Solid State Drive - SDSSDE61-4T00-G25M - Image 5](https://m.media-amazon.com/images/I/91Jdd5hzDhL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Questions & Answers **Q: how much faster is this than an external HDD?** A: With an SSD over HDD, you're obviously paying for the increase in speed. Nobody actually answered your question of "how much faster." Even though it's been over a year now, maybe it will help someone else. A typical portable HDD speed seems to be about 120 Mbps, whereas this drive claims 1,050 MBps read and 1,000 write. So about 8 or 9 times faster. Also, it is pretty fast relative to other portable SSDs. 1 GBps seems to be about the standard right now for drives in this price range. The T7 quotes the same speed, from what I can tell. Definitely not "3-4x" faster. The X5 quotes twice the speed (at twice the price). **Q: How to get the full 1000 mb/s? only getting about 800 mb/s write and 700 mb/s read. plugged directly into a macbook air m1 (2020). blackmagic test** A: The numbers quoted are for the raw data rate - how fast the drive can accept bits. You will never see this in real life. Some factors affecting real-world performance include: * File system overhead. Your file system (whether FAT, NTFS, HFS, APFS, ext or anything else) has overhead. This overhad consumes bandwidth, but you won't see it in a benchmark that only measures the data used by your files. * Your testing application may not be getting enough CPU cycles or USB bandwidth to be able to push data at the device's maximum speed. Testing labs use a computer with a specialized operating system that can ensure sufficient bandwidth, but an app running on a normal operating system can't make such a guarantee. **Q: It's not showing up on my ntfs for mac but is in finder. also keeps asking me to authenticate in order to do anything with it?** A: Ntsf is a windows format. A Mac will not write to it natively. You will need to get 3rd party software like Paragon or another to fully work with a ntsf formatted hard drive on a Mac. Format it to apfs if it is only going to be used on a Mac or buy ntfs for Mac software if you need to go back and forth. **Q: Can I use this as an additional storage *continuously* connected to my mac? any overuse or overheat issues?** A: Since my poor MacBook Pro 2016 has gotten slower because I refuse to update the OS (because I know what would happen), I started using my 2TB 1050mbps SSD Sandisc external drive for my heavy video editing and music production projects and it flies without any problem. I would say though that it is true that at some point it gets quite hot but nothing’s affected it’s performance. My advise is just connect it when you need it and that’s it. I love this little friend!! ## Customer Reviews ### ⭐⭐⭐⭐⭐ 🔥 Blazing Fast, Ultra-Compact, and Totally Worth It! *by M***S on January 27, 2026* I absolutely loved my purchase!

It’s pre-formatted to exFAT, which works with both MAC and Windows. Unfortunately, it DOES NOT WORK WITH the iPhone 11 Pro, which is what I bought it for. I read a bunch of great Amazon reviews, as well as YouTube reviews and videos. The one or two reviews I missed were the one’s that said this SSD is not compatible with the iPhone 11 Pro. I tried using it in conjunction with an non-Apple lightning to USB 3 camera adapter. When that didn’t work, I purchased an Apple lightning USB 3 camera adapter. The adapter has a built-in lightning cable, to attach it to the iPhone or iPod, and on the back side there’s a lightning port. This port can be used to connect the adapter to either a DC or portable external power supply. It also has a USB 3 port, that can be used to attach a camera, or other device. Once I connected everything to the iPhone and powered up the external power supply, I received the message, “Cannot Use This Accessory Extreme 55AE: This accessory requires too much power,” and the iPhone would not recognize the SSD. I checked to confirm that it arrived pre-formatted to exFAT, and it had. I ended up chatting with two Apple technicians, and an Apple supervisor. I pointed out that there are a number of videos that demonstrate the “how to…” use the SanDisk (and other) SSD’s to copy files to and from the iPhone 11 to the SSD. The bottom line was that the Apple Techs’ insist that there is no way to use an external storage device with an iPhone, even by using their Lighting to USB 3 camera adapter. Now, I’m an old-timer, so there’s certainly the possibility that I’m just not sharp enough to figure out where I went wrong. But, what I am sharp enough to figure out is how easy it is to return this beautiful little SanDisk SSD to Amazon for a refund. Love dealing with Amazon, but that’s another story. Even though I returned this SSD for a refund, I’m giving it all five stars, because when I connected it to my Windows 10 laptop, it was instantly recognized. Since I purchased this SSD to work with my iPhone, not my laptop, and knowing that I would be returning it, I didn’t try to transfer any files to it. Would I recommend the SanDisk Extreme Portable SSD to a friend? Only if my friend didn’t intend to use it to transfer files to or from their iPhone. ## Frequently Bought Together - SanDisk 4TB Extreme Portable SSD - Up to 1050MB/s, USB-C, USB 3.2 Gen 2, IP65 Water and dust Resistance, Updated Firmware, Monterey - External Solid State Drive - SDSSDE61-4T00-G25M - Case Compatible with SanDisk 1TB 2TB 500GB 4TB/for SanDisk PRO Extreme Portable SSD, External Solid State Hard Drive Storage Holder for SDSSDE61/ SDSSDE60/ SDSSDE81/SDSSDE30/SDSSDE60 (Box Only)(Green) --- ## 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.co.za/products/532624916-sandisk-4tb-extreme-portable-ssd-old-model-up-to-1050mb](https://www.desertcart.co.za/products/532624916-sandisk-4tb-extreme-portable-ssd-old-model-up-to-1050mb) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-08*
