SanDisk Extreme Portable SSD 4TB (up to 1050 MB/s read, 1,000MB/s write, USB-C, NVMe Solid State Performance, IP65 rated for dust and water resistance, Updated Firmware) Black

Been using this for a bit now and it’s been great. Really fast when moving big files and doesn’t lag at all. Small, lightweight and easy to carry around. Does exactly what I need it to do, no issues so far, very good for content creation that need more and more space.

I've been a loyal customer of SanDisk for quite some time now, and the SanDisk Extreme 2TB portable NVMe SSD continues to impress me with its exceptional performance and reliability. This is actually my third purchase of this fantastic device, and I felt compelled to share my positive experience. First and foremost, the speed of this SSD is simply mind-blowing. With read speeds of up to 1050MB/s and write speeds of 1000MB/s, it's like having a turbocharger for my data transfers. Whether I'm transferring large video files or working on intensive photo editing tasks in Lightroom, this SSD handles everything with ease. It significantly reduces the time I spend waiting for files to load or transfer, making my workflow smoother and more efficient. The durability of this SSD is another standout feature. Its water and dust-resistant design give me peace of mind when I'm on the go. I can confidently take it with me on outdoor shoots or in less-than-ideal conditions without worrying about data loss. SanDisk has truly built a device that can withstand the rigors of real-world use. Moreover, the sleek black design of this SSD is not only aesthetically pleasing but also functional. It's compact and lightweight, making it easy to carry in my bag or pocket. The USB-C connectivity ensures fast and hassle-free connections with my various devices. What I appreciate most about the SanDisk Extreme 2TB portable NVMe SSD is its excellent value for money. SanDisk consistently delivers top-notch performance and durability at a price that won't break the bank. In fact, I've made it a yearly tradition to upgrade to a new one because the improvements are always worth it.

Great drive. Fast too. Compact and sturdy

My main reason for buying this 1TB ssd was for when I travel and and have lots of camera footage to backup from my shoots. Portability was a big factor, and hoping it would work with iphone (since there isn't a lot of info on it) The ssd itself works well however max transfer speed I've seen so far is approx 270 MB/S on magicbook pro using default hardware, nonetheless faster than my other HDD's. I have noticed it heat up a lot in use, more than the 500gb version. In terms of wire / usb-c port connection, it feels a little flimsy and weak. The ssd has a front patterned surface and a rubber back both of which seem to attract dust. Now onto iphone connection...I have tried both the 1TB and 500GB versions (with the supplied usb-c to usb adapter), both work with iphone (12 mini) via a genuine Apple Lightning to USB 3 Camera Adapter (make sure adapter is original as fake / defective wires have given me an unpredictable intermittent connection). In my experience the 1TB ssd loaded faster than 500GB on iphone. Now Iphone allows you to view ssd contents BUT as soon you start saving iphone files onto it or tinkering with the ssd's data you get the infamous 'This accessory requires too much power' sign. Even if you re-connect the ssd, once the sign appears once it keeps coming back. What worked to reverse it for me was actually connecting it to a laptop and deleting the iphone files saved on the ssd or the folders where data was altered. Another option is to scan for errors (whilst plugged into the computer), even if there are no errors I found that often the ssd starts working without needing 'extra power'. Another option to try, this has given mixed results tbh is to connect the ssd to iphone whilst it is switched off then turn it back on and see if the sign reappears. If you definitely want 2-way iphone-ssd use then you will need a power hub to power the hardrive (and also bypass the '...requires too much power' message, or if none of the above options work to get rid of the message). I bought the '...RSHTECH 5 Port USB 3 Hub with 4 USB 3.0 Data Port + 1 Fast Charging Port Portable USB Splitter with 12V/2A...' because it provided more power i.e 24W compared to similarly priced 5-port power hubs - so far so good! As a bonus iphone was able to read both ssds (1TB + 500gb) at once when plugged into the power hub. In terms of folder load time there was no difference for me using a power hub vs none. I didn't notice a difference in performance or predictability between an old iphone lightning cable vs latest lightning to usb-c cable. I have tried iphone (with ssd connected) plugged into a usb wall socket vs plugged into an apple 30w adapter, again no obv difference. Another point to mention, with big folders around 90gb (raw files/4k videos) my iphone struggled to read the content despite loading for 20+ mins? The successful cut off for me has been around 65gb folder size max, anything larger definitely gets divided into smaller folders. I did notice some large 4k videos load slowly and freeze midway, but the ssd did let me save them directly on my iphone despite this so was able to view them better that way. My Sandisk ssd-iphone experience so far (in summary): Option 1 - viewing/saving ssd content on iphone -> no power hub required Option 2 - deleting/altering ssd content and/or saving iphone content onto ssd -> power hub required Hope that helps, I struggled A LOT to find info on iphone sandisk ssd connection so thought I'd share all of my recent findings. On a sep note - the ssds worked absolutely fine with ipad Air 4th gen utilising it's usb-c port so no adapter required. Literally a case of plug and play - and definitely a lot faster than on iphone.

I have used this particular brand of storage for years with the same trustworthy results. The unit is small and compact yet boasts the saving of a massive 2 Terabytes of data. Now comes with a cable end converter that allows both USB 2.0 and USB 3 connection, which should facilitate almost all computer connections. The data transfer is quite fast and the process to use is simple. Once plugged into a PC, whether Apple or Windows, the window opens up to display the pre-installed software that should be activated to make the drive secure. Once this is set up you should create a simple password for first time use. This then allows the unit to be protected against data loss. It can be configured to 'remember' certain PC's so as it does not ask for the password every time used. This feature is great because if you lose the unit - it will not allow access to your data without the password. The unit is lightweight and small enough to slip into any laptop pouch or a pocket or handbag. More than happy to recommend.

Take this everywhere I go and it works with everything. Easy to install and took no time to format. Good value. Get good speeds on transfers.

It suddenly and without warning stopped working, so I cannot access the content. It worked beautifully and fast whilst it did. I used it to transfer photos and videos and even edit a video. But whilst editing the video it got hot, so I had to keep an eye on that and go easy... It STOPPED WORKING one day when it was connected to the laptop and was idle, I was not using it, so that was a big NASTY surprise! It's a lovely bit of kit but UNRELIABLE!

This SSD is awesome, so fast and pocket size. SSD's have come a long way in the past couple of years.
