To be honest, I had never heard of MemoryCow but wish that i had in the past. Looking for this drive, my normal place , lets say its a Prime place, was £50 (or a shade under). I found this drive here, for £10 less and for that, I had excellent service, fast delivery and a product that's great and does what it says on the tin. I can heartily recommend this product and also MemoryCow and will be looking here first in future. (and no, I am not an employee/related to the CEO etc of this company, just a punter!)
