SanDisk 1TB Portable SSD – Up to 800MB/s, USB-C, USB 3.2 Gen 2, Updated Firmware – External Solid State Drive – SDSSDE30-1T00-G26

Use the factory USB-A to USB-C cable!
Some of the one-star reviews complain they did not get anything close to the stated 800MB/sec read speed. When mine arrived I fired up Crystal DiskMark 9 and did my own science project. First, I ran the SanDisk from my Asus ProArt 13 with a high-quality USB-C to USB-C cable (Anker). Results were indeed pathetic — 49MB/sec read speed. I was ready to write a flaming one-star review myself! Then I re-ran the test using the supplied USB-A to USB-C cable. I wasn’t expecting a big difference; I was actually expecting slower results. After all, everyone knows USB-C is faster than USB-A, right? Well, the numbers did not think so — the USB-A cable was good for reading 900+ MB/sec! Commensurate speed ups in write speed, too.The several lessons here: (1) never assume; (2) hold on to that factory USB-A to -C cable! It’s not very often you can get an 18X speedup in a piece of hardware just by switching cables.

This is a great choice for great price
I am really pleased with the SanDisk 1 TB Portable SSD. It’s so small that I can put it in any pocket, or slide it in any small space. It’s portable, compact, and efficient. I recommend this!

Impressively Small & Fast, Comes with Useless “Bonus” Software
TL:DR: Very fast, very small & portable, seems trustworthy, will likely buy again — but with a concern-inducing install procedure and utterly useless included security software.I’ve used SanDisk cards on & off in several cameras over the years, so when my backup drive died & took a couple of years worth of Time Machine backups with it, the 2TB SanDisk external SSD looked like a good step forward. It’s impressively small, and while the cable is a tad shorter than I like it’s still plenty long for basic everyday use. I did have to put an adapter on the end (standard USB to mini-USB for my MacBook Pro) but I’ve had to do that with a *lot* of devices so… no big deal. (Just keep the need for an adapter in mind if you’re buying this product.)The disk mounted almost immediately when I plugged it in, and I could do all the read/write/delete operations I’d expect to normally do. I opened the .dmg file to install the SanDisk Security app and had not problems… Until I ran that software and it kept telling me “Attach a supported SanDisk drive.” I then opened the “SanDiskSecureAccess” folder and instead of disk images found a pair of PDFs. I opened the one referencing MacOS downloads, read the short instructions, and clicked the “Ready to Download” link — and Safari opened a page on the SanDisk website that stated, “Not available. This answer is no longer available.” I tried searching on the website but finally gave up after confusing and/or hardware-only results.I then opened Time Machine on my Mac, then decided to rename the SanDisk drive (until now mounting as “External SSD”). The rename failed several times with the warning that the chosen name was either too long or had the wrong characters; it finally succeeded when I used just 10 letters, no blanks or other characters. I then went to add it to Time Machine and MacOS told me I had to reformat the disk because it was in an incompatible format. I copied all the files on it to a folder on my laptop and did the reformat, which completed in just a few seconds.By this time I had some misgivings but decided to push ahead (and am now glad I did). I restarted my MacBook Pro just to clean stray “stuff” out of memory, then tried the SanDisk Security program one more time — same results, it can’t see the new drive. I then went into Time Machine, told it to use the new drive as backup (not encrypted), and let it run — and about an hour later I had a full backup of the entire file system (appropriate, since it was the first-ever backup for this drive and my main drive only has about 180GB left free out of 1TB storage space).Since then, I’ve had multiple automatic hourly backups and three manually-triggered backups run successfully and quickly, glitch-free. I’m going to uninstall the SanDisk Secure Access app (it’s useless, but at least an uninstaller is included) and make sure I label the new drive properly. I’m likely to buy another one or two over the next year (one for photos and one for podcast files) because my external archive drive is old enough to be of concern… So I’m calling this one a 95% win, deducting one star for all the oddness of the prep, need to reformat, and over 30MB of wasted space for the useless security software.

My new product
Great product and a low price delivered on time.

Trata-se de um HD SSD externo muito bom e rápido. Pequeno e fácil de transportar em case pra HD SSD, embora infelizmente ela não venha com o HD.

サイズが小さいのでPCに簡単に付け変えHDDとは比べ物に成らないHDDも最近は小さいけど　もっと小さいPCの種類に差は有ります　が　USB3 接続で読み書き共に早い　満足しています

Good
