SSD and 7200 rpm drives in raid

[barry685]

Hi,
Im building a new PC. If this system includes a 120gb ssd as well as 2 - 7200rpm drives set up in a Raid 0 configuration which drive should be used for OS and programs and which for work files. This system will not be used for any video. Cpu will be Intel I7-2600k with 16gb memory.
Thanks

Hello,

...and what do you want to know ?

Best wishes

Use the SSD for OS/Apps and the RAID 0 for files. SSDs are blazing fast but simply too small to be useful for holding images.

Hi Niele,
What I meant by work files are the image files that are currently being worked on, they are stored on the drive temporarily. I will still have another drive or an external for general storage.

I understand that SSD's slow down their writes after many cycles.  The OS and application disk is written to infrequently and read from a lot so the write slow-down doesn't become much of an issue but your data file drives and especially temp and scratch file drives are continually being written, erased, and re-written.  Conventional hard drives are better in that role.

Modern SSDs don't really have aging issues anymore. For work files I believe either would be fine. Try both and see the perf?

All SSDs have these issues. New or old. The only difference is that the earlier generations could drop from 150Mb/s to 20Mb/s and the newer ones just drop from 250 to 160. Sure even the 160 is much faster than any HDD. (not even talking about 4k READ/Write where they outperform them even more) However, my limited tests show that for example a scratch disk is still better as RAID0 HDDs, compared to SSDs. (SSDs work if you have the time to reformat and earase them from time to time.

I decided to go the more expensive route and purchased 2 Crucial 128gb m4's. Will use 1 for OS the other for work files. Not implementing the raid feature.
