What HDD is needed for a video distribution server?

Question

Hard disks

Which HDD is better to choose for distributing video content (one movie 1.5, 2GB) with a limited speed (300 kb) per user, will simultaneously download 200-250 users, I tend to 2xWD VelociRaptor 1TB (RAID 0) or 4xWD Se WD1002F9YZ (RAID 10 ). Channel: 1GB
Will these drives handle the load?

Answer 1

IMHO, but it's better to use the WD Red series for file cleaning.

Answer 2

more depends on the volume, it is better to refuse raid in such a small configuration
On nginx, almost any 4 screws with aio and lumpy reading will easily give out two gigabits.

Answer 3

1) there should be several disks.
2) The RAID array must be of the appropriate level for throughput and I/O operations.
it is better to test in real conditions, tk. synthetic calculations do not take into account many parameters.
