Fast read and write large data pack on hdd
<p>I have this issue. I have a list of file names.Each consists of date, hour and other int like parameters. Ex. 20130505_1240_8445_3336.ext. I broke it down to objects File(Int date, int hour, etc) And stored in List.</p>

<p>Problem is list contains 6 million Objects. My "slow" machine is making that list for 4 hours because of regexp i have to use there. I'd like to skip making that list every time i lunch program therefore i want to save it somehow. I tried to save it with binaryFormater as serialized object List. It was big, over 200Mb. I could easily save it but when i wanted to read it it was loooong wait. I would like to skip SQL part if i can. </p>

<p>Is there any smooth possibility to manage that big set of data? Preferably easily searchable and fast as can be. Speed is factor i care the most. Security have no matter to me. </p>

<p>Thanks in advance ;)</p>
