Vertex 3 was more expensive to manufacture back then. Regardless of whether Vertex 3 shares the same cheaper components internally with the Vertex 4, it will still be priced according to how much it costs when it first came out with normal price reduction over a few months afterwards.

read some review http://www.tomshardware.com/reviews/buy-ss...ion,3255-6.html, vertex 4 fair lower than vertex 3.

Vertex 4 is on a different controller, Indilnx Everest 2 which is a derivation of the Marvell controller which is more stable and reliable but slightly slower. The Vertex 3 uses the Sandforce SF-2281 which although is faster in some tests, are very unstable in the early days. I don't know about your Vertex 3 but it just so happens that it is one of the most unstable Sandforce drives out there. Given a choice right now, I'll go for the Vertex 4 over Vertex 3 which the Vertex 4 has shown improvements in speed from firmware updates.

this is my crucial m4 256gb with asrock z68 extreme 3 gen3

define unstable pleaseee

1. Random BSOD without any particular reason.
2. Possible of data corruption.
3. Firmware update for count-less time and yet same issue.
4. Give up and try to use other brand SSD.

But Intel Sandforce has been prove stable, AFAIK, but it's still quite new so... "waiting game"?
Anyway it's up to you to choose, but most people here would recommend something stable rather than got frustrated with complaint threads later.

Thank you, I'll stick to Vertex 4 then!

Issues of Intel 330 is starting to creep up slowly according to some sources, don't know how true are they.
My data collection doesn't say much has changed, again we can only tell by the end of the year or next.

It does show. Using m4. Will ss for you later

to all the sifu here...sorry that i might ask the same question... but now i'm very blur now...1st time know that ssd need to learn so much of thing.

i plan to get a 120gb ssd, which brand of the ssd that you guys actually recommend? looking for reliability and performance. thx in advance

is there any refference of LATEST ssd price and performances...it will be useful if pinned for a newbie like me
p/s just a suggestion

M4 Crucial! 128GB.

how about when it come to comparison between ocz vertex 3, intel 330 and samsung 830...all 120gb range

I would go for Samsung.

can i know the reason why? coz seem like intel 330 more stable compare to the rest.

guys, my 520 just died for no reason. cant even see it inside bios
is it warranty time? or is there any solution for this?

What is the best option nowadays? Toggle mode NAND or asynchronous NAND?

I bought and tested two 60GB SSD, Mushkin Chronos Deluxe and Force3. Was initially looking at Vertex 4 but gives up after reading it has lower iops. It does not seem like Toggle NAND equipped Mushkin beating Asynchronous NAND like Force GT comfortably. Is Toggle mode NAND still in the picture? Thanks you for your insight.

all sifu... can i ask is tis speed is normal or slow? im new in here
using intel 520 120gb

intel 330,crucial m4 or samsung 830.for laptop? 128GB

IMO if you often dealing with compressible files, 330 will do.
else, M4 or 830 will do.
