File Compression & Encryption:

Website: WinRAR
We used the Intel X25-M SSD to provide a uniform performance base between all the boards tested in file compression and decompression.



Again we see very little difference between the boards but on average the DS4 performs ever so slightly better than the UD4P.

File Decompression & Decryption:

The two RAR archives created during the compression and encryption tests were then decompressed and decrypted.



In decompression there's a little more favour for the UD4P here in large file handling, but overall it's not much between all the boards.

Multitasking Performance

Website: MPC-HC
Website: 7Zip

To run multiple applications well you need a powerful (ideally multi-core) CPU and plenty of RAM. Our multitasking test performs a massive file backup (with encryption) using 7Zip, while simultaneously playing back a HD movie file using Media Player Classic, making it a seriously demanding test for any PC.


The UD4P again tops the table, but by a small margin, with the DS4 running a few seconds slower but still mid-field.
