If you look at their forums - there seem to be FAR fewer issues with the Vertex4's than there were with the sandforce drives. Hopefully the Marvell controller works out for them.
True, but preliminary newegg reviews don't look great for the V4, even though it does seem a bit better than the OCZ Sandforce models -- the Vertex 4 has 14.3% below-average reviews on newegg, which is significantly worse than comparable Plextor and Crucial models with a Marvell controller.
Saying that the OCZ Vertex 4 is better than the OCZ Sandforce models is similar to a car salesman saying that THIS car is better than a Yugo. Not exactly a ringing recommendation!
I just went through the newegg reviews for current (and recent) SSD models from Plextor, Samsung, Crucial, Intel, and OCZ. I computed the percentage of below-average (1- or 2-egg) reviews for each manufacturer, and in some cases, for particular models.
Overall percentage of below-average reviews by manufacturer:
3.5% Plextor
6.5% Samsung
7.2% Crucial
10.1% Intel
25.4% OCZ
Here are the percentage of below-average reviews for some specific models, also included the old Intel G2 model which is not included in the overall Intel percentage above (all capacities of a given model grouped together):
3.7% Plextor M3
4.3% Intel G2 X25-M/V
6.5% Samsung 830
7.2% Crucial m4
9.5% Intel 510
10.3% Intel 320
11.0% Intel 520
14.3% OCZ Vertex 4
23.3% OCZ Agility 3
26.2% OCZ Vertex 3
26.7% OCZ Solid 3
27.7% OCZ Vertex 3 Max IOPS
34.5% OCZ Octane
53.3% OCZ Petrol
NOTE: These are the percentages of below-average REVIEWS. You should NOT assume that this is the percentage of buyers who are unhappy, since many buyers do not write reviews. These percentages should only be used for RELATIVE comparisons between manufacturers and models, since such comparisons can be valid with the reasonable assumption that each manufacturer and model has roughly the same chance of an unhappy (or happy) buyer submitting a review.
