SF-1200 vs SF-1500- Real World Differences?

Basically, I'm stumped between an Agility 2 and a Corsair Force.

They both have the SF-1200 chip, but... the Corsair Force has the "unlocked" firmware that allows it to do 50k IOPS in 4k aligned writes, while the Agility can only do 10k IOPS.

Is there a real-world difference between SF-1200 and an "unlocked" SF-1200 (basically a SF-1500) for personal, at home computers?

Thanks guys!

yes there is. id get the corsair force or mushkin castillo deluxe. IOPS are how many Input output operations per second your drive can perform. It comes into play when dealing with small files such as 4k read and writes. If you have a drive that can do 50k but its limit to 10k you feel kinda sad

This is not totally true, the agility2 can sustain 50k for about 10 sec then it starts to degrade toward 10k.

10+ sec of 100% 4k random read is pretty rare, In real-world situations you will never notice it.

I'll update with the link, but the benchmark I saw they had to write a special case just to show this difference.

On the otherhand if its only $10 difference just buy the vertex2

Edit:

I kind of mis-read your question.
Nope. It is a firmware difference.

This should be interesting eheh.

basically what we already know also since its enterprise it works with a large cap that stores power to finish write in power failure.
"Let's start with the obvious and what I suspected: there is no physical difference between the SF-1200 and SF-1500. It's the same die. The difference between the two amounts to firmware, validation and settings on the chips themselves. It's akin to Intel disabling Hyper Threading on the Core i5 750 but leaving it enabled on the Core i7 860; same die, different features."

1500 comes with a big capacitor for enterprise data security.

There are three firmware lines.... SF-1500, SF-1200 "SE", and SF-1200. While the physical controller is basically the same, the SF-1500 platform does have a physical difference. It expects a large cap to allow it to complete writes from cache in event of power loss.
