We're upgrading our server for our startup company that went live this past Sunday.

I was curious what some of the top brands/models of SSD drives that people would recommend. I will be using it in an raid array, emphasis on performance and reliability. This will be used in a server running SQL Server.

Is CDW the best place to price out the drives and a new server or should I shop around at theEgg, etc...?

I you look at Enterprise SSDs with a good reliability, best write performance without a heavy speed degration after some time of usage, check Intel's S3700 serie.
 
This is a probably a dumb question, but if we had to choose between 4x100GB and 4x200GB for a RAID 10 configuration, should we automatically go with the 200GB?

Are there any benefits for performance, reliability, and/or expected lifetime by going with the smaller sized drive?

Unfortunately I think we are priced out for any SSD's much larger. This is for a SQL Server installation.
 
A larger drive based on the same model (so that it uses the same controller and flash) should be expected to have a longer expected lifetime based on wear leveling since there will be more to wear level.
 
With SSDs, there is no real need to build Raid-10 like configs for best I/O.
SSDs are 100x better regarding I/O than disks, so this is obsolete.

I would use one mirror with a pair of large SSDs if your storage need is below 800 GB
If you care about reliability, build a 3way mirror. Try to stay below 70% pool fillrate.

ps
I have made some benchmarks about some pool design principles, you may check at

Thanks!

I snagged this and will digest it later, looks like a lot of useful information.
