That's more like it. Depending on the positioning of this Vertex 5, I don't really see a place between Vector (awesome drive, IMO a hair better than the 840 Pro) and Vertex 4. There isn't even a lot of room between Vector and the max bandwidth of SATA3, only smaller file type speeds. I did hear Vector has some issue with the first firmware being vulnerable to sudden power loss in a unstable overclocked system - they got a firmware out to resolve it but come on... if you don't know how to overclock don't.
Samsung's 840 Pro is still pretty comparable to the Vector. If price was the same, and power consumption (especially at idle) was NOT a factor, I'd give Vector the edge too! But the reality is that Samsung's 840 Pro drive is still excellent, and it's more affordable. It regularly goes on sale too. Right now there's about a $50 delta between the 256GB models. I'll take the $50, and spend it on a better processor or graphics card.
I hope every drive gets a firmware update. I am glad Windows gets updates even if a few bork some systems. I am glad OSX gets updates. I am glad my AV software gets definition updates. I am glad my Sony TV got an update or the Netflix would have been endlessly unwatchable. Updates and continued support is a good thing. Nothing electronic "just works" under ALL scenarios and under EVERY variable. There are so many variables and continuous change in PC computing which is why we have updates. Heck, a couple 840 Pro samples even died in professional reviews including one by Mr. Shimpi - they had to fix it.
