SanDisk claims that Extreme 900 is capable of transferring files with the speed up to 850 MB/s (read/write). It’s because Extreme 900 supports USB 3.1. It also includes a USB-C port. Well, the test showed that what SanDisk claimed was not proven. In the USB 3.1 test it scored a sustained copy speed of 313MB/s and 269MB/s for writing and reading. With USB 3.0, it registered 165MB/s and 260MB/s for writing and reading. Still, this drive is by far one of the fastest portable drives on the market.

SanDisk Extreme 900 design

As mentioned earlier above, the design of SanDisk Extreme 900 is not too cool, especially if you are a fan thin-sized device. The design of this portable SSD is a bit bulkier than some portable SSDs available in the market today, say Samsung T3. However, it is still reasonable and you can keep be able to slip it to a large pocket. SanDisk Extreme 900 is protected by a shock-resistant aluminum and rubber casing.

In addition to its shock-resistant casing, there are several other features you will get from Extreme 900. As you can see from the specs table above, Extreme 900 features 128-bit AES encryption. To be able to use this security feature, Extreme 900 also comes preloaded with security software (SanDisk SecureAccess). Once the software installed, you can protect your files with 128-bit AES encryption. It’s just, you need to truly be careful if you want to use this feature. Once you forgot the password, you won’t be able to access your data anymore. In other words, you would be losing your data. Only use this feature if you think you really need it.
