[H]ard|OCP just wrapped up a review of the 120GB Samsung 840, using their own ARM Cortex R4 based MDX controller and TLC memory for storage. They compare the speed of this drive to the 256GB 840 Pro, Kingston's V300 120GB and the Intel 335 240GB to contrast the difference the type of NAND used can make to performance. This is especially evident on the write and latency benchmarks, which fall well behind the competition. From [H]'s testing it is apparent that TLC memory is very vulnerable to reduction in size, the reduced channels really hurt performance and put the 120GB model far behind the larger sized 840s which they have tested with much better results.

"The 120GB Samsung 840 Series SSD features the powerful 8-channel MDX controller and TLC NAND. While this value SSD comes at a very good price, it also features much lower speeds than its larger capacity brethren. We put this value SSD through our suite of steady state tests to see if it can pass muster."

As the lifespan of flash memory in SSDs has become a topic of concern for many users, it is nice to see that the Samsung 840 500GB has a lifespan of some 14 years assuming a daily write load of 10GB. Since most users do not write 10GB to a drive day in and day out, that estimate is probably on the low end. If that doesn't have you excited then consider the cost of the drive, at $350 it is much lower than the $1/GB mark most other SSDs are at. There are some trade offs however, [H]ard|OCP saw comparatively slow extended write speeds though the read speeds were higher than the 256GB model. When you consider this drive do keep in mind that it is still going to be faster than a platter drive even when it is working on a task that other SSDs might do slightly faster.

"Samsung has released the first TLC NAND equipped SSDs into the market, creating the lowest price points we have witnessed for SSDs bringing large capacity SSDs within reach for average users. Today we test the 500GB TLC Samsung 840 Series SSD to test the performance in steady state of a large capacity TLC Solid State Drive."
