The Corsairs that are readily available here are using Sandforce controller. So I guess no one dare to recommend it . Mostly going for the more reliable Marvell based controller, but for the Corsair (marvell based) need to import and the price is on the high side.


BTW TS add me to the user list

tskhang | Crucial M4 | 128GB x 2 | RAID-0
tskhang | Corsair Performance Pro | 256GB x 2 | single mode
tskhang | Plextor M3S | 128GB
tskhang | Intel X-25M G2 | 160GB

Nope, with PCIE 2.0 X 1, you only get max 500MB/s from the card.
Using 2 of your SSDs in raid, each will share the 500MB/s,
therefore you are actually getting the performance of a single SSD, maybe less.

You should be looking for at least a PCIe 2.0 x 2 card (500MB/s x 2 = 1000MB/s). But on the market, after x1, the next cards are in x4 (2000MB/s) and x8 (4000MB/s).

However, there are things which you need to research carefully, such as compatibility with your motherboard, your SSD, performance issues (different chipset/hardware-based/software-based RAID) and if the card supports booting.

Another point to ponder, since everyone knows that Intel SATA chipset gives the best performance for SSDs, so far none of the RAID cards are using Intel chipset. Heck even Intel branded RAID cards are just a re-badge of LSI cards. So the performance you get from a RAID card even with sufficient bandwidth, might be somewhere the same as your current on-board RAID controller. Some might improve the write speed, but decreases the read speed and VICE VERSA. It really depends on the characteristics of the RAID card.

Yes, LSI is one of the highly rated RAID cards out there. But even that, I have seen reviews from people saying it did not give them the full performance expected off their SSDs.

Yes, I did mention it depends on the characteristics of the RAID card.

The multiplies of the speed is a theoretical calculation of each number of lanes from a PCIe. That would be a general start to determine the capabilities of the card minus whether the RAID is able to perform at its max or not.

He did mentioned he was considering about a PCIe x1 lane card, so even that alone is already not suitable for RAID 0 2 SSDs, whether it can perform at max or not

IMO forking out on a RAID card, not knowing whether it will perform up to your expectations or not does not justify it, unless if your motherboard currently does not support RAID.

Your motherboard only have 1 PCIe x1 version 1.1, so no point to have RAID card, it would only run around your current speed.

Yes, or use your current mobo until you decided its time to upgrade. In terms of real life usage, with your SSD running at 250MB/s, it would still be faster compared to your HDD.

AS SSD or CrystalMark, link on the 1st post.

If you are upgrading from a HDD, then yes.

Like I said, if you are comparing a HDD to a SSD, you will notice a lot of difference, even if your SSD is running in SATA 2. However, difference between running SSD in SATA 2 and 3, the experience would be minor.

Yes
However, there are some requirements for it to work. Refer here
