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 - External Solid State Drive - SDSSDE61-4T00-G25

I’ve been using the SanDisk Extreme Portable SSD (1TB) to back up photos and video, and it’s been one of the most useful pieces of gear in my kit. Transfer speeds are genuinely fast, so moving large batches of RAW files or video clips takes minutes instead of forever. Drives in this line are rated around 1000–1050 MB/s read and ~1000 MB/s write, which makes a noticeable difference when working on tight timelines.  The size and build are a big plus. It’s small enough to keep in a pocket or camera bag, and the rubberized shell feels rugged. These drives are designed with water and dust resistance and drop protection, which gives some peace of mind when traveling or shooting outdoors.  Setup is simple with USB-C, and the included cable and adapter make it easy to use with both newer laptops and older USB-A ports. I’ve used it for everything from field backups to editing directly off the drive, and it’s been consistently reliable. If there’s one small downside, it’s that like most compact SSDs, it can get slightly warm during long transfers, but nothing concerning. Overall, it’s a great portable SSD, especially for photographers, videographers, or anyone who moves large files regularly. Fast, durable, and easy to carry, which is exactly what you want in a travel drive.

This seems to work pretty well. I don't have much to compare it to, since my last external drive was a disk drive, but it transfers data relatively fast and I like the password protection feature that comes with it. I haven't tested the limits of the storage, but I have used it right after it was in the cold (about 15°F) and it worked well. It's also a nice compact size, but not so small that it can get lost easy. Overall, I think this is a solid option for external storage. I bought a case for it separately, and it gives me some additional peace of mind that it won't be damaged, so I would recommend buyers do that, too. Is it worth the price? So far, so good. I'll definitively say yes if it's still working well in eight years or so (that's how long my old external disk drive is and it still functions well).

This is a great, compact external storage device suitable for documents, photos, and videos. I have the 2TB one and it holds all the info I need it to. I will likely purchase a secondary one in the future in order to separate my side hustle documents. I found the use of this portable SSD to be extremely simple and quick to figure out. Files transferred very quickly and quietly without overheating the devices in use. I appreciate the type C ports to plug directly into my MacBook, with the option to have a USB port for other computers. Highly recommend and likely will purchase another in the future.

What I liked the most is that it transfers files very quickly, so saving time when passing videos backups or jobs is a great advantage. In addition its size is super practical because it fits easily in the hand or in a backpack. and it weighs almost nothing

So once I got to the point where the library I wanted to carry around could no longer fit on the biggest USB powered drive I could find, I was having more and more of my bag taken up with storage. Well now I have the same amount of storage in less than a quarter of the footprint, including the protective cases. Less room required, higher performance, and no moving parts so it's noiseless. Yes it's definitely pricier, but if you can afford the additional cost you get the value back in convenience and performance. Can't wait for the next upgrade.

I purchased this drive to use as a local mirror/backup for a large Lightroom photo library (~2 TB and growing). While the drive works fine for short file transfers, it repeatedly disconnects during long, sustained write operations. I tested different cables, ports, and configurations on macOS, and the behavior was consistent: the drive would unmount during heavy continuous writes and cause backup jobs to abort. This may be fine for casual use or short transfers, but if you’re planning to use it for large photo/video archives, long backup jobs, or continuous mirroring, I’d recommend looking at a more conservative, thermally stable SSD designed for sustained workloads. I’m returning it and switching to a different model better suited for long-duration backups.

軽量で保存容量が大きため重宝しています。 iPadと接続して使用していますが、反応も早いためお気に入りです。

Very cool delivery, on time, very happy with the SSD drive, it is a little more expensive than the usual one, but since my previous hard drive failed and I lost all my data irrevocably, it is better to get a reliable drive, although the price is higher for the sake of reliability and quality.

Great otem

Works great ! Love how compact it is. Speed is great.

This is SSD is insanely fast provided you connect it using a USB-C cable and is very compact for an 8TB capacity it's insane! It is very reliable coming from a well known brand such as SanDisk.
