i got a question the reason i change in my efi bios to ahci rather ide was because i seen a major increase in read/write speeds...now let say if i get another ssd to make it much faster and majorly more space should i raid it?? and if i do then how will this effect my hhd's i have and my dvdrwr i have on the sata ports??? please any help would be great,...thanks...this is my setup just incase you guys want to see my built:::: http://youtu.be/PJA9YDKE8Hc http://youtu.be/PJA9YDKE8Hc
A second SSD will obviously give you more space, but there is a trade-off. If you raid the two together, it will definitely increase sequential read/write speeds. However, you lose the ability to keep the SSDs nice and fast with TRIM implementation. I know the drivers don't support it, and from my reading I'm pretty sure you can't use the toolbox to do a manual TRIM.
So on one hand you get nice and fast speeds - but on the other, you effectively shoot yourself in the foot in doing so. When the performance begins to degrade, you;d need to image backup your installation, break the array and do a secure erase on each SSD, before re-creating and restoring the image backup.
An alternative is to manually manage putting data/programs on each individual SSD. Probably a pain in the arse, and you'll probably wish you had bought a single larger SSD. You won't get RAID-performance for sequential read/writes, but at least you won't have to worry about TRIM.
In regards to optical drives or other HDDs, if theyre not part of the array (obviously not optical / dvd drives) they just show up like normal in windows. You create the array before you install your operating system, and this array is what the OS will see as a logical disk. Non-member disks or other drives just appear as normal.
ps. i looked at your video - you appear to have the memory modules installed both in "Channel B" (i.e. single channel). Check your BIOS post screen (unless it has the fancy graphic enabled, which hides all this information), or google a program called "CPU-z" - it has a memory tab which will tell you if you are running in single or dual channel.
oh okay so i wouldnt mind getting another ssd just two sepreatly not raid then and have them as ahci...as for the memory yes i do see them as single how could i fix this??
You should have 4 dimm slots. 2 one color and 2 another color. Put the ram in the same color slots, usually slot 1 and 3. Each slot is a different controller, with 2 sticks they both need to be on the same controller.
what should i do about this... please help...some people just dont disable this..but i did...so should i not disable this...ii dont mind reformatting all and do this step???help thanks....
Well, to see it in effect, benchmark your new SSD (pretty much done). Then, fill it up so all blocks are written to (if you run the full diagnostic scan from within the intel toolbox, it should write to pretty much the entire SSD, save a few gig) and then benchmark again. You might have to leave some time after writing to it so TRIM can do its thing.
The only way to know TRIM is working is via testings before/after a few GBs of random writes/deletes.
1) If your OS supports TRIM (W7, Linux, FreeBSD, OpenSolaris, etc)
2) If in Windows, run "fsutil behavior query DisableDeleteNotify" via CLI. If the result is '0', TRIM is enabled by the OS.
3) What SATA driver are you using? (Microsoft or Intel only)
4) Confirm the SSD is plugged into a controller using the MS or Intel driver.
If all four points are met, you can assume TRIM is working.
im using the intel rapid storage technology 10.1.0.1008 for sata...
im using windows 7 home premuim...
its plugged into the 6gbps sata port on my asus motherboard...http://www.asus.com/Motherboards/Intel_Socket_1155/P8H67M_PRO/ http://www.asus.com/Motherboards/Intel_Socket_1155/P8H67M_PRO/
is this good??
can you specify the run to 0 proceedure please...cmd or regedit??
"fsutil behavior query disabledeletenotify" only tells you that the TRIM command is being sent by the OS. It does not necessarily mean it is being executed by the SSD.
no what im saying is that 0 means that the trim is enabled by the os right? but is there no way of knowing if it is exactly doing it with a app? or such?
It means that trim is enabled. your SSD supports trim. It is a logical assumption that the SSD is being Trimmed. You will know in future benchmarks when the ssd maintains the same performance. If you want to test it, open the Intel toolbox, run the full diagnostic scan. Wait a few hours, then benchmark it again. If your benchmark is close to the one you have already done you will know that trim is working.
Don't forget there are drivers and controllers between the OS and SSD, which can prevent a TRIM command from reaching the SSD.
TRIM commands are sent by Win 7 by default. (0). If a TRIM command gets to a TRIM enabled SSD it will execute the command by default. Exactly when the TRIM command is executed by the SSD is down to the SSD.
With a TRIM enabled OS & SSD "all" you need to do is make sure your controller can pass the command.
The default Win 7 MSAHCI driver enables TRIM pass through as do the Intel RST drivers.
If you use any form of a raid array however TRIM will not be passed to the SSD, unless the SSD is a non member of raid array. (There is some evidence that a pure software raid can pass TRIM, but no concrete prove).
Intel were going to provide a matrix that helped people understand if a system configuration could pass a TRIM command, but they never got around to it.
Shame, because the question is asked over and over again.
