On a Flash memory disk, read speeds are always faster then write speeds.
Is Trim enabled?
Type this cmd
fsutil behavior query DisableDeleteNotify
It will give you one of two results, either a 0 or a 1. A zero indicates that TRIM is enabled correctly, a one means that it is not. If you have a TRIM-compatible SSD, but find that Windows 7 hasn't enabled the command, you can easily do so by running this command:
fsutil behavior set DisableDeleteNotify 0
Even write speed being relative "low" as 130 MB/s it's still good and you wont notice any difference with a higher write speed as most operations on a drive are read.
My opinion: Don't worth a change.
