After many weeks trying to decide between the M4 and the samsung 830 i eventaully went with the OCZ Vertex. It dropped 40$ and i couldn't justify paying that much extra for two ssd's that supposedly perform slower.
Reliable? eh ocz is ok but i hear terrible things about their rebates... and that's 20 of the 40 i saved... lol
also the crucial m4 and samsung were 128gb vs. OCZ's 120gb but i was told that is because they left extra room on the sandforce ssd's for some reason.. longer life maybe? prevent u from filling it over 90%? something like that....
Anyways in the 120-128gb range taht is my reccomendation.
tbh though i dont think you can miss with any of those! great choices
None of the SATA III drives have been out long enough to Get a real user defined reliability, But you can get a good feel for "user Problems"
Generally the M4s, Samsung 830, and Intel 510 & 520 have about the best "satisfied" ratio when compared to the rest. (Note: the Intel 520 is the Only SF22xx that gets hig marks)
My recommendation has always been: M4s samsung 830s, or the Intel 510/520. Which One - Which of the three is on sale. If all three were within 10 bucks, then as listed, but in reverse order.
Have 2 128 gig M4s and one 128 Samsung 830s and 2 120 Gig agility IIIs (NOT REcommended)
PS: Outside of benchmarks - In real life usage you MIGHT see a nickels worth of diff in performance, And then again Might NOT - LOL
Bottom line, Samsung 830 or M4, which ever one is Cheapest and ENJOY it!!!
