Samsung TurboWrite endurance

[sambrightman]

Several reviews - including Anand - have mentioned TurboWrite on Samsung 840 EVO and newer drives increasing performance. Nobody appears to question to what extent the SLC zone wears out, since it is dealing with every write to the disk in a concentrated area. I also note that the endurance tests use very large continuous sequential writes, which likely take the buffer out of play. Does anyone have a bit more detail on the technology? Can it wear out? Can the TurboWrite zone move around?

SLC zones have 100K write endurance so why bother? MLC is like 10K and TLC like under 3K.. Huge difference in their performance.. Also using a disk cache helps with the endurance as you write out finished blocks rather than every bit of data you send to the drive. It all helps.. Both caches help write out longer and bigger blocks so less erases take place. I dont think mass copying files would help in any saved writes using these techniques.. But take the swap file where a lot of little bits of data are written and read all the time. It helps in such situations. In many cases the turbo write zones can be set to a percentage of the drive, unless they are separate chips like some on some kingston drives which uses 5 or 10GB of SLC to cache data.
