Our first custom file transfer test uses a single large compressed file and has been dominated by the Samsung SSD 840 Pro with a throughput of 330MB/s. The new Evo 840 drives did nothing to change this with their offering of 200MB/s – roughly 40% slower than the SSD 840 Pro. In fact, the performance of the SSD 840 EVO drives was comparable to that of the OCZ Vertex 4, Octane and the much older Samsung SSD 830 series. With RAPID enabled, the Evo’s performance improved significantly, with the 250GB model seeing a 19% boost from 196.8MB/s to 233.4MB/s and the 1TB version jumping 32%. We honestly didn’t expect RAPID to have much of an impact on these file transfer tests, but the results speak for themselves.
The Evo drives performed much better in our program copy test, which is comprised of many small non-compressed files (6104 files totaling 2.75GB). At 183MB/s, the 250GB and 1TB drives delivered performance on par with the OCZ Vector and Intel SSD 335. This time, however, RAPID only allowed for a minor 5% performance bump, which still left the Evo 5% behind the SSD 840 Pro.
The game copy evaluation is a mixture of small and large, compressed and non-compressed files (1336 files totaling 2.70GB). Although the SSD 840 Pro excelled in the previous transfer tests, the Evo drives were the fastest SSDs we’ve tested, with the 250GB model reaching 266.6MB/s and the 1TB model hitting 277MB/s. Enabling RAPID only increased performance by 3% for the 250GB model and 9% for the 1TB drive.
