Out of those 4, I would choose the Mushkin Enhanced Chronos Deluxe.
It's one I usually suggest. It's a good reliable model.
In all honesty, it's really just that I'm torn between the Chronos Deluxe and Corsair Force Series GS. Both have similar specs, and the reviews look good for both.
EDIT: I did find, however, that the GS has some issues with AMD based north/south bridges, which results in SATA 3Gb/s speeds instead of 6Gb/s. Researching on the Chronos now...
The Chronos is probably the best priced, I admitted the Corsair Neutron is probably the better performer right now, but using a relatively new controller is an unknown factor. Atleast with that particular sandforce controller you know it's going to last, It's had time to prove itself. The Corsair GS, it's nothing special, it's new, but the Chronos was doing those numbers last year.
Yes I agree it's not the fastest because the Neutron beats it, but it's not 25% faster, maybe less than 5% faster. It's negligible when it's comes to know why you buying will be reliable with your data and will work without issues.
If money is not really an issue, the Corsair Neutron has the best guarantee at 5 years I believe. I might be wrong but most are 3 years. Worth checking out if their is any fine print on it. But that is nice to have if the worst happens.
