The impact in performance you noticed can be caused by different reasons, here are some possibilities based on the information you have provided.
- We have to consider that the Intel® SSD X25-V was released in 2010, as well as your motherboard.
- The configuration of your system does not support TRIM, so the write performance of your SSD's may decrease over time. TRIM is not supported in RAID configurations. For more details about this, you can check the following document:
- You might want to check the health of your Intel® SSDs by reviewing the SMART counters, as it is possible that a failing drive may be causing performance degradation.
- It would be advised to perform a back up of the data, then update the SSD firmware, as well as system BIOS, and RAID adapter driver.
Use Intel® SSD Toolbox to check the status of the drives and update drive firmware.
Guess I should have stated that, Motherboard is on the latest bios version, raid adapter driver is the latest, as is the firmware of the SSDs. All SSDs check out as healthy with no issues in the SSD toolbox and a few other programs for comparison.
As for trim, should I really expect to see that dramatic of an effect with the hours/time on the drives? I know they are "old" but they sat powered off for nearly 2 years when I wasn't using the computer. Guess I'd have to ask some people benching really high numbers still with their X-25 series drives in a raid what they have hour wise.
Guess I didn't think about Trim as to me the drives don't really have that many hours. If the lack of Trim issue is that bad(that 2400 is a lot for an SSD raid0, probably will keep me from running SSDs in a raid until that changes I guess.
Unless you have any other suggestions, and I appreciate the ones so far, I'll have to dig into this more and decide what I want to do.
