Am I a victim of the placebo effect? Please tell me!
I read a lot here how RAID 0 is not improving desktop performance, although it does improve the sequential transfer rate.
Well, I may be just experiencing the placebo effect, but I think it did improve performance of some apps in my case.
Here are the examples of the performance improvements I have noticed in some standard desktop applications when working with big amounts of data, tell me what you think:
1. Windows Media Player with a big media library.
Switching to the media library for the first time after player startup takes quite a lot of time with my collection of 13000 mp3s.
The library database is stored in a single 78MB file.
Seems like a sequential read to me...
2. Outlook Express startup with a lot of email (btw, i'm not using it anymore, for security reasons)
Takes a lot of time to start up with a lot of emails stored (about 2000 messages).
The email is stored in a couple of files that add up to about 300MB.
Again the read seems pretty sequential...
3. Windows Explorer
Expanding a folder the with a lot of subfolders (300+).
I think that's a sequential read, but I'm not sure. If you know NTFS, please educate me;)
If I'm correct these are examples where the sequential transfer rate plays a dominant role in slowing the application down (the drives work intensively, while the CPU doesn't) for a couple of seconds - which can be pretty irritating.
Please tell me if these examples are wrong for some reason and it's just my perception, or if these are indeed pretty much sequential reads and RAID 0 could in fact improve the performance in these cases.
