ssd for video editing

[beginner99]

My Dad wants to buy a new Computer for home video editing. As far as I understood the biggest bottleneck for this usually is the harddrives and CPU. It's suggested to run the OS and Applicaltion on a different drive from the video/project files.

My first idea was to go RAID 0 for video files. 1 Tb 7200 drives are around 100.- here. Space is not an issue but aren't 500 Gb drives slower? (because older, less dense?) Also the don't seem to be much cheaper, like 80.
Besides the risk RAID 0 with the default Intel RAID consumes CPU time. No idea how much, but because CPU is other limiting part I thought why not get an ssd for this?
The crucial 128 GB would be available for 279.- here which is a little more than 2 1 TB drives but not much and sure less if you buy a separate RAID controller.

Thoughts?

is 128 Gb enough space? Assuming it's only for working not for storage? I never done it. Do you work with raw files? = much more space. encoded files would be a non-issue.

Get the two 1TB in RAID0.

SSDs usually are not as good with writes as with reads, plus their big benefit besides faster transfer rates is with access times, AKA random reads, where they totally destroy spindle drives.

Doesn't video stuff do more sequential reads/writes? Two modern 7200RPM drives with 500GB platters in RAID0 should be close to the sequential reads of an SSD and best it in writes. The king of SSD writes are ones with Sandforce controllers, which don't do too well with uncompressable data.

Yeah I read some other stuff. Depending on how you edit (compressed/raw; SD/HD) and Effects projects supposedly can get huge, eg. larger than 128 GB. Not to mention the wear on the ssd.

Thanks!

EDIT: one restriction with raid 0 is case space, eg meaning bigger case needed. ssd can be put anywhere with tape...

Are you seeking approval from us to twist your dad's arm into buying a big SSD or are you really trying to find him the best solution without going overboard with cost?

no I agree raid o is the way to go + 1 separate ssd/hdd for OS. He prefers a small case and small cases with many internal hdd bays are very rare.
