Update : (My original review is not deleted you can read it below)
Don't bother buying this SSD and I'll explain why , loading in games were VERY fast, computer boot to desktop in 5 seconds after Bios screen "literally" after i have optimized everything of course, reading+writing speed was superfast etc performance wise this ssd was a beast, but then the unexpected happens
BSOD "Blue screen of death which will force your computer to get stuck/force shutdown" this SSD is not reliable at ALL in the long run, yes if you use it for 1-2hours you might get lucky and not get the BSOD but YOU WILL get BSOD guaranteed if you keep your pc on a lot, (my power settings is set to never turn off HD and everything is optimized trust me, i have followed step by step guides by OCZ and did troubleshooting with their forums+customer support for a week and the issue still remain EVEN AFTER i did RMA the first drive, i have tried the SSDs on more than 1 computer and the issue remains) so far after 3 week of use i usually get 1 BSOD a day on average, only 2 days i did not get BSOD (but again some days i got 2 BSOD in the same day) tons of people are posting about their BSOD in the official forums and OCZ answer is "RMA it because we can not recreate the issue in our lab" they want to keep you in the RMA loop hoping maybe they fix the issue later on maybe via firmware or to let your return window pass since RMA takes a while, their last 2.06 update did not help much either, it have removed the random daily freeze and replaced it with more BSOD
To make it short for you.... OCZ rushed the drive to the market, they want you to BETA Test it, you are stuck with them the moment you buy it, they will keep you in their "RMA or wait for firmware Loop" this SSD is a big "AVOID IT" for main drive (OS+Programs/etc) it will annoy you to no end and a solution atm as of may 26 does not exist neither OCZ admit it yet even when plenty of people are reporting the same issue, they will always try to blame your other hardware or software for the BSOD and never about their own SSD
If you want to be a beta tester go ahead and buy it, OCZ got no solution to offer atm, they are basically selling a product that works 90% of the time so some users wont notice it (those who use their computer 1-2hours a day) if you leave your computer +5hours a day or on all the time prepare to a daily BSOD, Until OCZ offer a solution this SSD get a 1 star from me "(would give it 0 if i can), replacing the SSD with another brand SSD or HD stops the BSOD so it's not a hardware issue from my computer, OCZ have reached a new low where they actually close threads when people complain about the BSOD, their excuse for closing some BSOD threads? not "everyone" is complaining about the bsod issue and if it was an error from their side (like buggy firmware) everyone should have the issue ! their solution is RMA your SSD if you are not happy, they refuse to admit the flaw in their SSD so don't expect any serious improvements anytime soon
PS : if you plan to use this SSD for a laptop, make sure you have access to a desktop first to update the firmware or a laptop with 2 HD slots , you can not update the firmware to 2.06 if it was your main drive (external usb etc wont work too) you need to have it linked directly to a motherboard, and make sure you have SATA3 because this drive is slow on SATA 2 (compared to many other SATA 2 SSDs)

(My Original review)
If you want a full Review about Vertex 3 there are plenty of those online, I just wanted to clear something up here.
(Update : Benchmarks below at the bottom)
Regular Vertex3 120GB = 4KB Random Read 20,000 IOPS/4KB Random Write 60.000 IOPS
""MAX"" Vertex3 120GB = 4KB Random Read 35,000 IOPS/4KB Random Write 75.000 IOPS
Regular Vertex3 240GB = 4KB Random Read 40,000 IOPS/4KB Random Write 60.000 IOPS
""MAX"" Vertex3 240GB = 4KB Random Read 55,000 IOPS/4KB Random Write 65.000 IOPS
(120GB Max got faster Write IOP yep also the Vertex 3 240GB MAX IOPS Max Write speed dropped from 520MB/s to 500MB/s)
Everyone should know that The only difference between the regular Vertex 3 and this MAX IOPS Vertex 3 edition is that MAX IOPS Edition got faster 4KB random write performance 75,000 IOPS (The regular one got 60.000 IOPS only) and it also have faster 4KB Random Read 35.000 IOPS versus Vertex 3 Vanilla at 20.000 IOPS
4KB Random speed is actually much more important than Sequential Access Read/Write (Sequential speed are important mainly if you are moving or copying very LARGE files which is rare to do to be honest when we are dealing with a limited 120GB storage)
What matters for real world use is the 4KB Random speed so the increase from 60.000 IOPS TO 75.000 Write should increase performance in theory but this speed boost wont be noticed by the average desktop user, where it actually helps is when you benchmark or if you are what i call "SUPER MULTITASKING USER"
Keep in mind that Random 4KB READ speed is also increased, The random read speed increase is massive and make it now almost as high as the 240GB regular Vertex 3, it seems that OCZ decided to release the max version because many reviews actually did point out that the 120GB Vertex 3 is not as fast as the 240GB version !, 4KB Random speed is the most important thing in your SSD imo (and reliability) , even with all those improvements I'd say if you find the regular Vertex 3 cheaper you should get it over the MAX IOPS Version unless you multitask heavily, I actually bought the MAX version for 50 box less than the regular version (Vertex 3 prices are going over MSRP right now due high demand)
If you want the BEST version of Vertex 3 then MAX IOPS is better than the Vanilla version that's for sure, however you shouldn't pay much more for this version over the regular version imo unless you need the extra speed or if the price difference was not much between the max and vanilla version, pick the cheaper one and you will be happy about it.
I'm happy with Vertex 3, I would not recommend the intel 510 series due the much slower 4k random speeds (But intel got the most reliable SSDs so far it seems plus Intel 520 are already leaked and will get released at Q3/Q4 2011, intel gonna increase the 4k random speed with 520 SSDs) the M4(C400) and C300 SSDs are solid drives with fast 4K random speed that is worth a look if you want cheaper but good options.
