I am still hopeful for some customized options to manage the cache.

Once the Magician 4.6 is released and if there is something worthwhile to mention, I would update this article. The read cache is persistent, meaning a copy of the data map is written to disk every so often. The most noticeable about the write cache is it focuses on small random I/O by collating the data and writes it back in larger blocks. The cache size is dynamic, 25% of the RAM up to 4GB, split 50/50 between read and write. Based on the previous version, the RAPID technology uses the computer host SDRAM as an extra level of cache. Without it, there was no RAPID feature to test. It is unfortunate that the Magician 4.6 was not available for this review. Once the buffer is full, subsequent writes fall back to TLC performance. As long as the writes stay under the buffer size (buffer sizes below), write I/O should perform as SLC speed. In my opinion, TurboWrite is very ingenious solution to provide SLC performance.īy reserving a small portion of the V-NAND as emulated SLC, that space acts as a buffer, all I/O writes perform at SLC speed. Beside the performance increased, the endurance rating was greatly improved allowing Samsung to offer a 5 year warranty compared to the 3 years for the previous EVO generation. TLC or MLC 3 bits per cell really take advantage of the V-NAND since there are more bits cells compared to the MLC (2 bits per cell). The benefits are, less retries due to interferences, lower power consumption. The benefits are, less retries due to interferences, lower power consumption, increase NAND endurance and overall I/O performance Which translates into more room for voltage state changes, less interference and lower programing voltage. By going vertical, there are now more real estates for the cells in size and in between.
Instead of shrinking, V-NAND stacks vertical layers. Which are the most relevant I/O type regarding user experience. Although per Samsung, the MGX has been optimized for low capacity model and sequential read/write and random low level QD. The MGX is a dual core controller, which would be a “downgrade” compared to the three core ARM, MEX. I am going to summarize the internals and features. The only real difference is the form factor. The components and features of both drives are the same as the 2.5in big brother. TCG/Opal V2.0, Encrypted Drive (IEEE1667)

Only the PRO version offers a 10 years limited warranty. 5 years limited warranty is now the norm for the EVO line. form factor ranges from 120GB, 250GB and 500GB. The mSATA version is available in 120GB, 250GB, 500GB and 1TB (1000GB) while the M.2. There will be no new features nor ground breaking innovations, both drives are built with the same components as the 2.5in version but housed on a smaller PCB. What it means is, expect the same great performance as the 2.5in version but with a smaller footprint. While the mSATA version was expected, the M.2 was a pleasant surprise since that format is favored over the mSATA. It did not take long for Samsung to release two new form factors of their EVO series, the mSATA and the M.2.
