I'm happy so far....
Did you install the latest: Intel Rapid Storage Technology 9.6.0.1014 driver?

question for those of you with SSD, say i buy a 40gb SSD and fill 30gb with my install, will that hurt performance it being that full? i know with mechanical drives they slow down the fuller they get. does this apply to SSD?
Sorry but TRIM is not supported with these drivers on RAID0 or any other RAID volume. TRIM will work with (non member RAID) drives when the system is set to RAID in the BIOS, but you will not have TRIM support on any drive in a RAID array.Yes and for those who want to know Trim is supported in Raid 0 with the Vertex LE (sandforce)

It doesn't matter if it's 2x Intel G2 in RAID0/1/5 or 2x Sandforce based drives in RAID0/1/5. As soon as you build a RAID0/1/5 array from the 2 or more SSDs, TRIM is not passed by the RST drivers to the SSDs in the RAID0/1/5 array, the TRIM command is blocked by the RST driver.So even though they have trim support that is triggered, and then passed down from Win7 with these drives in an individual state... That would make all non Intel SSD drives not able to get Win7 trim support through the Intel ICH chip to the SSD drive sorta making it a monopoly. No?

However, using the RST driver, it is possible to still use RAID mode in the BIOS for ICHxxR and have TRIM support, as long as any SSD that you want to have TRIM support on is not part of a RAID0/1/5 array. In other words, any drive you wish to have TRIM support on, must be set to non member RAID in the BIOS.
You can also use the RST driver in ACHI mode and have TRIM support.
TRIM is just not passed by the RST driver for any SSD in a RAID0/1/5 array, and i personally have serious doubts if this will ever be possible in the near future with any reasonable level of safety for a RAID array.
I'm a little bit fuzzy on the difference between garbage collection and TRIM, maybe someone else can explain it for us.
Garbage collection sees blocks on the drive that are partially full and joins them with other blocks that are partially full so it "frees" up space for the drive to write to. Not doing so is why write speeds degrade over time. Garbage collection also wear levels the drive so different parts the the drive get written to equally so the drive doesn't wear out.
TRIM is when the OS tells the drive to delete a file, and tells it to cache the information that isn't being deleted from the block so the entire block can be erased and loaded with the information that is being kept. Without TRIM the block keeps the old data in it after it is deleted.
Ah, very nice :thumbsup: Thank You
Actually flash drives are known to get slow when they start to get full. The Vertex LE is only 100gb because it keeps 20% of the space is reserve to keep performance up as the drive ages and as it gets fullAs far as I know, no.

Here is exactly how much free space matters:
SSD Toolbox "optimization" was run prior to each bench. No other system settings were changed.
17.2 GB free:
25.8 GB free:
Pay particular attention to the write speeds.
Subjectively, there is also far less stalling when a large seq write is taking place, and the results are also more stable.
As far as Intel drives are concerned, they should be sold as 60GB drives for all practical (performance) purposes. This is basically a known fault of Intel's write combining algorithm - it works fast and beats the pants off of anything else with under high queue lengths, but needs plenty of free space. (anand discussed this in one of the articles).
thank you for that info, i was going to get 40gb SSD now i am going to get the 80 instead.
