Yes, it's resolved. Do I indicate it somewhere?
I think as a thread owner you can choose to mark the thread resolved at the very first post of the thread. Most people don't. I didn't see you say Thanks, i ordered it or something that that I wasn't sure if that was the build you are talking about here. That's all.
Is the TRIM support important? Also, would you recommend using one SSD
for OS/programs and the second as a cache for the HDD? Finally, does it
make sense speed-wise to put the SATA III HDD into the Intel SATA II?
It can be important. Depending on how much of the drive is filled and how often you write to the SSD / use your computer basically, there is a chance that you begin to experience delays after all blocks are written once if you don't have TRIM. And the only way to get the speed back would be not use the computer for a while, reformat the SSDs or delete some files etc if you faced that situation. Also, lack of TRIM causes uneven wearing of the SSD that it can shorten the life of the SSD.
Also, I would like to point out that there is no benefit of putting OS / programs files in a RAID 0 array if that is what you are thinking of. RAID 0 only improves sequential speed which is relevant in large size file transfers such as transferring pictures / videos. The sequential speed is good for storage drives and their back up drives. OS and programs operations depend on random speeds / access time, instead of sequential speeds. Their operations require the reading of a loooot of tiny bits of data like several kilobytes, that the time it takes for the drive to get to the next bits of data to be read, that is what determines the speed of OS / programs operations. And that "random speed" / "access time" cannot be improved by putting hard drives or SSDs in a RAID 0.
So basically you have nothing to gain performance wise by RAIDIng the SSDs so long as you use the SSDs for an OS or programs , and you just lose TRIM support. Lol.
I am not sure how effective the acceleration of the storage drive is. You could try, but usually the perk of using an SSD as a cache space for a hard drive is that you install both the OS and programs on a regular hard drive, and then you can cahce some program files save on the HDD into the SSD space so that those programs load at the SSD speed.
SSDs do not necessarily have faster sequential speed than hard drives though most do. They are more for "random access time", not sequential.
So, it would make sense to
1. Run the Intel SATA controller in RAID "mode"
2. Run one SSD on Intel SATA III header for the OS
3. Run another SSD on Intel SATA III header for the programs
4. Put two storage hard drives in RAID 0 for faster sequential reading and writing, or RAID 1 for redundancy.
I mean as far as the speed of your 'data drives" is concerned you can improve the sequential speed by putting a lot of hard drives in a RAID array. At least that way you get more space for the money you spend lol. Using a more expensive SSD for the caching of a storage drive does not make sense to me..... unless you are doing something I can't think of right now. ...
