how much faster is this than an external HDD?

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).

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

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.

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?

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.

Can I use this as an additional storage *continuously* connected to my mac? any overuse or overheat issues?

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!!

3rd Purchase. Never misses a beat.

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.
