is it worth buying a Western Digital WD Blue WD10EZEX 1TB 7200 RPM HDD with 6gb/s (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) AND a SAMSUNG 830 Series MZ-7PC128B/WW 2.5" 128GB (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)? in terms of speed, would the HDD match up with the SDD? If it does, i'd rather not spend the extra $90 and just go with the HDD. Thanks

Hard drive won't come close to the SSD. Without a benchmark on those two selections it's hard to give you a number, but the SSD will be 10 times faster. For what I do an SSD is exactly what I need. And data hungry application does benefit from an SSD

While that blue drive has good sequential speeds (150 MB/s on average), the average seek time is 20 ms. The seek time of an SSD is less than 1 ms, typically 0.1 to 0.5.

I use that blue to back up my ssd, because backups are streaming sequential access, not random.
