SanDisk has been widely considered as one of the best brands of storage devices right now. This is because the company always delivers high-quality products at reasonable price points. Now, if you are looking for an affordable and budget-friendly SSD to upgrade your personal computer system, most probably, you are currently torn between SanDisk Z400S and SanDisk X400. We have talked about both models quite a lot in our previous articles, and both are very good for the money. Nevertheless, let us now see the comparisons before making a decision.
Design and Capacity Choices
Even though both SanDisk Z400S and SanDisk X400 are generally affordable and budget-friendly, it is interesting to know that SanDisk Z400S has indeed been designed to be a budget model, aimed for people looking for a low-cost upgrade from HDDs. SanDisk Z400S requires only low power consumption. On the other hand, SanDisk X400 is a higher model with additional features. We can be certain that SanDisk X400 has been made to be more robust, durable, and reliable. Nevertheless, both models come in the 2.5” form factor, which is very compact and lightweight, making them suitable for use in a limited space such as in a laptop or a notebook.
SanDisk Z400S is only available in two capacity choices, which are 128GB and 256GB. Meanwhile, SanDisk X400 is available in 128GB, 256GB, 512GB, and 1TB. In general, a larger capacity is better and more cost-efficient, as it allows you to use the storage device for a longer time before needing to get another one.

Performance and Features
SanDisk Z400S is very popular not only because of the low price, but also for the excellent performance. It claims to be able to outperform HDDs by a factor of 20, at the same time providing 5x more reliability at just 1/20th of the power consumption. It indeed makes a very good budget upgrade from HDDs.
However, SanDisk X400 has even better performance. It is especially much faster than SanDisk Z400S when handling mixed random read/write operations. This is because SanDisk X400 has been packed with the nCache 2.0 technology, which buffers the data in an SLC layer before sending them to the DRAM Cache, effectively and significantly enhancing the data transfer rate. Last but not least, SanDisk X400 is armed with TCG Opal 2.0 support for better data security and protection.
