Question 1

SanDisk Extreme Portable SSD or Samsung T7 Shield 4TB: which should I choose?

Accepted Answer

Their published peak speeds are the same: up to 1,050MB/s read and 1,000MB/s write. Both are rated IP65 and for drops up to 3 meters. Choose the SanDisk if its carabiner loop, compact shape, or included USB-C-to-USB-A adapter better suits your setup; compare current prices and availability if those features are not deciding factors.

Question 2

Should I get this SanDisk Extreme or the Extreme PRO for faster transfers?

Accepted Answer

Choose the Extreme PRO if your computer supports USB 3.2 Gen 2x2 and faster transfers matter: it is rated up to 2,000MB/s read and write, versus this drive’s 1,050MB/s read and 1,000MB/s write. On a host without Gen 2x2 support, the PRO’s rated top speed may not be attainable, so this Extreme is a practical fit for standard USB 3.2 Gen 2 connections.

Question 3

Is this 4TB Extreme faster than the previous SanDisk Extreme Portable SSD?

Accepted Answer

Yes, based on the published maximum speeds. This model is rated up to 1,050MB/s read and 1,000MB/s write; the earlier 550MB/s generation was rated for up to 550MB/s read. Choose this model when faster transfers and 4TB capacity are useful; actual speeds depend on the connected device, port, and workload.

Question 4

Should I buy the 2TB or 4TB SanDisk Extreme Portable SSD?

Accepted Answer

Choose 4TB if you need more room for large photo, video, or game libraries without swapping drives. Choose 2TB if that capacity covers your needs and you prefer a lower-capacity configuration. Both are in the same product line, rated for up to 1,050MB/s read and 1,000MB/s write; the choice is primarily about storage capacity.

Question 5

Can I use this SSD with both Windows and Mac computers?

Accepted Answer

Yes. The SanDisk Extreme Portable SSD is listed as compatible with Windows and macOS. For sharing files between both systems, check the drive’s format and reformat it if needed; reformatting erases existing data.

Question 6

Can I use it to back up a Mac?

Accepted Answer

Yes. Best Buy’s product Q&A says the drive can be used with Time Machine on a Mac. The drive itself does not guarantee automatic scheduled backups; set up a backup tool such as Time Machine.

Question 7

Can I back up photos and videos from a USB-C phone?

Accepted Answer

It can work with compatible USB-C smartphones for file backup. Phone compatibility and the steps for accessing or transferring files depend on the phone; SanDisk’s Memory Zone app is listed for supported Android devices.

Question 8

Is it suitable for carrying files while traveling?

Accepted Answer

It is designed for portable use, with a carabiner loop, up to three-meter drop protection, and an IP65 rating for water and dust resistance. These protections do not make it waterproof or protect it from every kind of damage.

Question 9

Is the SanDisk Extreme 4TB reliable enough to be my only copy of important files?

Accepted Answer

It should not be your only copy of important files. Reddit users have reported failures, data corruption, and freezes on 4TB Extreme drives, while other users report trouble-free use. These posts are anecdotes, not a failure-rate estimate; keep a separate backup.

Question 10

Will the 4TB Extreme Portable SSD reach its advertised speeds?

Accepted Answer

Its listed maximum is up to 1,050 MB/s read and 1,000 MB/s write, but actual speed depends on the host connection and setup. Reddit users report varying results across USB-C enclosures, so the maximum should not be assumed for every device or connection.

Question 11

Is the 4TB Extreme Portable SSD suitable for video-editing work?

Accepted Answer

Its 4TB capacity and listed speeds up to 1,050 MB/s read and 1,000 MB/s write make it a candidate for storing or working with large media files, but reported freezes and failures mean it is safer to use with a separate backup rather than as the only location for active projects.
