Basically, no it's not as bad as customer reviews make it seem.
For one, those who buy on perceived quality (of the company, product and support combined) generally will go with Intel. They'll also know that Intel has awesome support when you need it. They'll use that support and generally have a positive experience even if they have to RMA the drive. Less people with problems on Intel drives will end up at the point of posting a review.
Those who buy on price are likely to get OCZ, or perhaps sometimes Corsair on a good deal. People who buy on price frequently aren't too solid on how their warranty works. They're also likely to bitch really loud at the drop of a bit. There were definitely issues with Sandforce drives and OCZ in particular at different stages of their availability. There have been a rather large number of firmware revisions and then throw in the 34->25nm switch inside the same SKUs. Really a bad move for OCZ, I for one will not purchase their products again. A higher percentage this type of buyer will post a negative review on a bad experience, even a bad experience with a happy ending. They'll also neglect to update the review with the happy ending part.
I have 2 OCZ Vertex 2's that are running just fine, never an issue and both get hit reasonably hard. Here's the one in my 24x7 home server drive is ~245 days old:
Code:
9 Power_On_Hours_and_Msec 0x0032 100 100 000 Old_age Always - 5912h+09m+33.540s
12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 25
231 SSD_Life_Left 0x0013 094 094 010 Pre-fail Always - 1
241 Lifetime_Writes_GiB 0x0032 000 000 000 Old_age Always - 960
242 Lifetime_Reads_GiB 0x0032 000 000 000 Old_age Always - 2624
When I bought OCZ I was going on 2 things, price and my understanding of the performance of SF based drives. I need high 4k random IOPS both read and write. At the time of purchase it was my determination that the Vertex 2 had what I needed at the right price. I was also willing to take a slight gamble on less than great support if the drive should fail. I've had all kinds of hardware fail and dealt with everything from Intel's great support (dead CPU) to non-existent defunct support (abit mobo).
Given that I am happy with SF based drives for my needs it's looking like Corsair is going to be my go-to since I've dealt with their support before (RAM and PSUs) and it is definitely among the best in smaller companies. (When I say smaller, I mean smaller than Intel/HP and similar)
