Box fresh SSDs are all very well, but they don't stay that way for long. Before testing, we give every SSD a going over by first installing a full copy of Windows 7 and then filling it to the brim with data. With early SSDs, this often exposed long-term performance problems. Happily, the latest SSDs take this sort of abuse in their stride.
