USB Flash Drives
SSD: Form Factor, Capacity, Memory Controller, Interface, Sustained Sequential Read, Sustained Sequential Write, 4KB Random Read, 4KB Random Write.
HDD: Form Factor, Capacity, Interface, Sustained Sequential Read, Sustained Sequential Write, RPM, Cache.
USB Flash Drives: Capacity, Interface.
Media: Speed, Capacity, Read/Write/Re-writable.
Operating System: You want something with really good Random Access Times and 4KB Random Read and Write speeds. This is why SSD's seem to be the fastest out of any other form of storage when installing an operating system. The better the Random Access Times and 4KB Random Read and Write speeds, of the drive that the OS is installed on, the more responsive the system appears to be and can also dramatically decrease boot times.
Programs/Games: SSD's are still the best choice for this use, because the faster Random Access Times and 4KB Random Read and Write speeds seem to dramatically decrease the load times of the games or programs. However, since SSD's still have a high $/GB ratio especially when compared with HDD's, it is common place to see people moving their games and programs to a high RPM HDD or RAID configuration. A high RPM HDD or RAID configuration can also be more beneficial than an SSD in some respects for programs and games that continuously write to the drive, as some SSD's, especially those of the 1st Generation can have dramatically shortened life spans if continuous writes are to be made by the programs or games on the drive.
Data/Files: HDD's are want you want to be using for data or files as they are generally considered better than SSD's for moving larger files such as videos or pictures. Also HDD's are much cheaper than SSD's and also offer a greater capacity meaning that you will have the ability to store more files and be more cost effective. The cheaper price of HDD's makes it much more affordable to put together RAID configurations, which are popular for storing files as you can create RAID arrays which have elements of redundancy, so if one of you drives fail, your data will still be intact. RAID 1 and 5 are both popular configurations to use when storing important data.
Media: Media is more commonly used for movies and music, and it is more common to see both blu-ray discs and DVD's than other forms of media these days. DVD's, while good, their capacity limitations and technological limitations at time of release means that they are only capable of putting out 720p video, which is not you full HD resolution, and is also only capable of holding a 5.1 surround sound audio track. However, blu-ray discs can put out 1080p, full HD resolution video (and now 3D) and is capable of holding full HD, 7.1 surround sound audio tracks, making them ideal for audiophiles and movie buffs alike. Then depending on what playback the video requires to be smooth will determine the speed that the disc must be, and as for whether you want it to be Read/Write/Re-writable, the user can determine what editing privileges they want.
