QLC is still pretty new, but it has much less endurance, but still on the order of years. TLC drives can be measured in many years. Any bit that is used too often will be ignored/data moved so that it isn't always getting burdened.īut good MLC SSDs durability can be measured in decades of normal use. Both SSD and hard drives will do wear leveling. SSDs will remove bad flash cells if possible, drives that are over-provisioned are best at this. HDD will attempt to recover data from bad sectors and move them to new ones, then truncate the bad sectors so they aren't re-used. Now both storage types have mitigation techniques. You also can't permanently store data on a hard drive, they do have a shelf life.
The spindle motor and read-write heads will also wear out. You can't endlessly re-write to a hard drive platter, eventually the grains the data is stored with will fail. HDD are far less reliable, on average, then flash storage.

To do an update without a read/write operation.Ĭlick to expand.Not sure where you got that information.

That is because it will have a harder time finding free nand blocks Sort of an internal raid-0 if you will.Īlso, a SSD will slow down as it approaches full. They have more nand chips that can be accessed in parallel. In sequential operations, they will be 2x faster than a hard drive, perhaps 3x if you have a sata3 interface. They will be 50X faster than a hard drive. That is what the os does mostly.įor that, the response times of current SSD's are remarkably similar. What really counts is the response times, particularly for small random I/O. Most desktop users will do one or two things at a time, so they will see queue lengths of one or two. They are done with apps that push the SSD to it's maximum using queue lengths of 30 or so. 20 years in a normal desktop environment.ĭo not be much swayed by vendor synthetic SSD benchmarks. Unless you are in a server environment updating the ssd heavily, the evo will be just as good.īoth will be long obsolete before they wear out. Today, endurance is no longer the issue it once was.

The big difference between PRO and EVO is that PRO will have longer endurance.
