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!!

安心のSanDisk品質。速度も十分満足！

データ保存用に購入。安心と信頼のSanDisk製SSD。公称値は1050MB/秒ですが、体感的には平均700MB/秒ほどで安定しており、動画編集やデータ転送でもストレスなく使えます。価格は少し高めですが、その分の性能と安心感はしっかりあります。長く使える信頼の一台。

非常にコンパクト・・・

デスクトップ化したノートＰＣに繋いで、ＰＣの内臓ＳＳＤを、データ（ファイル）の保存先にしない為に購入。自身初のＳＳＤ、、、とてもコンパクトで驚きました。基本的にはモバイルユースにしないので、もっと大きくても問題なかったのですが、ＳＳＤってのは、「メモリーの大きいヤツ」ですから、商品にするとこんなサイズになるのは容易なんですね。。(苦笑) 時代は進んでますなぁ、、、その昔、500ＭＢのＵＳＢメモリーを買ってテンション上がってた頃が懐かしい。。(笑)

まぁ、普通に使えます。

そこまで特筆するような快適さはありませんが、このクラスでは良い方だと思います。使い始めて間もないので、耐久性は今後検証していきます。
