The Intel 330 is just under two years old and sports a Sandforce 2281 controller coupled with Intel's own 25nm MLC NAND. This combination typically produces a performance profile that struggles with incompressible data and favours reading over writing. With peak and average sequential read/write speeds of 514/138 and 414/122 the Intel 330 is unable to compete in today's market and falls over 50% short of the group leaders which manage peak sequential read/write speeds in the 500/300 MB/s region. Small file 4K peak and average speeds are better and clocked in at 32/89 and 24/63 MB/s which is 10% below the group leaders. Overall the 330 has an effective speed of 370 MB/s which makes it one of the slowest 128GB SSDs I have seen to date. [Feb '14SSDrivePro]
The 250GB Samsung 850 Evo has a similar architecture to its hugely successful predecessor, the 840 Evo. Both drives are TLC based but the 850 uses 3D V-NAND as opposed to regular NAND. Both drives also feature a Turbowrite cache (TWC) which buffers up to 3GB of writes. The TWC enables high burst write speeds but when the cache exhausts write speeds drop to 300 MB/s. Comparing the 850 and 840 Evos shows that effective speed, has improved by 11% and the warranty has been extended from three to five years but prices are also up by 11%. The 850 Evo does put in superb benchmarks (second only to the 850 Pro) but these are only valid within the TWC. At current price levels the 850 Evo struggles to compete with the value leaders.
