The SanDisk 2TB Extreme Portable SSD is a powerhouse! With read speeds up to 1050 MB/s and write speeds of 1000 MB/s, transferring files is lightning fast. The 2TB capacity is perfect for storing large files and backups. Highly recommend for anyone needing reliable external storage!
Got two of them for my iMac to replace my oldish hard drives. Worked from the box, several terrabites (upwards of 6Tb) of data transferred from old drives to these drives within one day. Accessing the data from these drives has improved the performance of my Ventura based iMac quite noticeably. They take up less room than the old hard drives and they don’t need external power. I’m pleased with them.
It’s size is its greatest asset and it’s greatest downside. You could fit it into a shirt pocket, if you had one but it is so lightweight that it doesn’t stay where it is put! Other than that it works exactly as it should. I am a Mac user and have so far encountered no problems.
Highly recommended if you can’t afford RAID storage.
I also use a Samung T5 and T7 SSD storage as back-up drives and needed some extra fast external storage. The Sandisk Extreme Portable gets good reviews overall. Both devices are small and very fast in terms of transfer speeds. When I looked on Amazon to buy another storage SSD there was a good discount on the Sandisk Extreme Portable 2TB so I decided to purchase it over the T7. I’ve given it 4 stars as I always use the password/encrypt feature of these drives to keep my data safe and I just find the Sandisk Unlocker software less easy to use than Samungs equivalent. When I connect the drive it is detected straightaway by windows but the Sandisk Drive Unlocker is slow to detect the drive and unlock. The unlocker .exe was also being blocked by windows, which I have now allowed through Controlled Access. Maybe it’s just my laptop but If it worked as good as the Samsung software does it would be 5 star.
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.
DRAWBACKS:
1. Transfer is MUCH slower than expected, regardless of temperature. Using the front USB3 port of my Windows 10 i7 PC, which has a very fast NVMe ‘C’ drive, it takes a disappointing 8 seconds to copy an album to/from the Sandisk compared with 5 seconds to/from my portable USB3 Transcend HDD. It only takes 11 seconds to/from a very old USB2 Buffalo HDD.
It would probably transfer faster via a rear USB port but I don’t understand why the Sandisk SSD is that slow compared with the Transcend. It is a bit tedious making large transfers, taking a whopping 60% longer than the Transcend HDD that I HAD hoped it would replace.
Copying to/from USB ‘C’ on my i5 Surface-Pro is a bit quicker BUT it takes a few seconds saying, ‘Preparing to transfer’ so a single album transfer is even slower.
2. It is so small that it is very easy to forget where I left it 😉
ADVANTAGES:
1. Small & easily pocketable – about the size of a Weetabix but half the thickness.
2. Robust – I think.
3. Fast enough – for most purposes.
4. Light – 58g.
A qualified recommendation!
UPDATE:
I have now found that transfer speed is MUCH faster if you use the very short cable that is provided with the device. Unfortunately it is difficult to use that with my set-up.
I still don’t know why the Transcend HDD is so much faster than the Sandisk SSD with a 1 metre, high quality cable. What is so special about the very short Sandisk cable?
What it does reveal is that there are genuine differences between digital cables. You often read claims that it is not worth buying expensive digital cables but in this instance there is a BIG difference. Is that purely to do with the length of the cable? I doubt it. Electrons travel along a 1m cable in an almost un-measurable time.
Although originally a sceptic, have long recognised that hifi interconnect and speaker cables really can make a difference to the sound. I am interested to learn that digital cables are also significantly different.
