What is IOPS?

what is it? what significant does it make for ssd? 

 

If possible,make Fast as Possible video please

Input/Output Operations Per Second. It's basically a measurment of how many random read/writes a storage device can do per second. In theory a higher IOPS count = higher performance, but in real life, it depends on a lot of other factors.

Input/Output per second. More operations means more operations in r/w it can do per second. To convert to MBp/s, use the theoretical equation: IOPS * 4 (because 4k random read/write) / 1024. If a SSD had a read of 85,000 IOPS: 85,000 * 4 / 1024. 340,000 / 1024 = 332 MBp/s. It's just theoretical, your mileage may vary.

i thought its related to the ssd longevity lol, apparently im wrong. how to know its longevity? if its possible

Look up endurance tests. There are lots of sites which get SSDs and put them under very harsh conditions with constantly reading and writing large files. They continue to test the SSDs performance every now and then to see when the SSDs performance really starts to degrade.

i see...thanks for the tip

longevity is not only related to endurance, but on other stuff aswell. Proper controller, the whole pcb design, firmware... Everything matters.

In fact, most of the SSD faulires don't come because flash wears out (that really happens rarely) but due to controller faulire.

 

 

tl;dr

Just dont be scared of all the reliability numbers you may get. Get a drive, that is most recommended (right now this is either mx100 or 840evo, whatever comes cheaper) and always use a backup.
