After Phoenix Pro who surfed the wave of the SandForce SF1222 controller, expands its range with G.Skill Phoenix Evo maintains the same controller, but sees its memory chips go into 25 nm. For what performance?
Instead NAND etched by 34 nm, Pheonix Evo therefore begins to date by providing chips 25 nm. Even if the controller remains unchanged, firmware it has naturally modified to support this new type of memory. Consequence of this firmware change, an over-provisioning revised upwards as 120GB for G.Skill Pro, we move to 115 GB. A situation that is found on the new SSD Corsair Force series, pass them also 25 nm.
Other figures revised downwards, those flows: while the Pro version of the Phoenix showed 285 MB / s read and 275MB / s write, the Pheonix Evo offers more than 280 MB / s read and 270 MB / s write. A very limited decline, certainly, but a decline nonetheless, at a time when other manufacturers commercialize 6Gbps SSD that panic counters.
G.Skill no end to sacrifice his Evo version with a MTBF which fall to 1 million hours, against 2 before, so that the security is of 3 years. And icing on the cake in the image of what was done on her OCZ Agility 3, G.Skill has opted for asynchronous memory, which seems to have a significant impact on performance in writing large files .. .
