Any info on internal RAID speed?

Hi everyone.
I have a P150 and a W350 here and I plan on using dual SSD in RAID 0 with both machines. Are the RAID cards on Clevos designed with those fast SSDs in mind? Is there any chance the RAID hardware will become a bottleneck?

 

On the P150 you wouldn't be limited by the Raid controller, but rather the Sata controllers themselves, The primary being a Sata III connection at 6gb/s vs Sata II at 3gb/s in the ODD and Msata bays.

The W350 does have two HDD bays and you should be able to raid across there with no issues or concerns for bottlenecks.

 

Why the raid setup? You really do need a specific use in mind to warrant the combined drives over a single larger drive.

 

Also, if I recall correctly, one - if not both of those models - use software RAID rather than a dedicated RAID controller chip.

But it's the end of a long day, so I may recalling incorrectly.

 

Thanks for the replies.

Arr... forgot this. [facepalm.gif] Was only thinking about pairing SATA III's and didn't realize I don't even have 2 of them.

Looks like OS-level soft RAID (two partitions on the SATA III paired with one on the SATA II, maybe plus another on the mSATA) is the way to go. Linux installs would be fine, but Windows is going to be left out of the configuration.

That would be great, at least for the W350.

I'm playing with 50GB+ datasets and the slow hard drive is getting in the way of productivity. If my calculations are right, even with 2 SATA III SSDs at full speed, storage I/O or swaping can still be the bottleneck for some operations.

 

even bottlenecked that ssd raid config is gonna make for one hell of a speed bump besides, depending on the size of ur individual database parts there wont even be any difference between sata 2 and 3, since those only limit the throughput of sequential data transfer of very large individual files like movies or bigass iso files. when it comes to I/O performance the sata 2 ports wont bottleneck ur raid setup (unless ur combined small file I/O of ur two ssd's exceeds 2x300MB/s, which i highly doubt )

The 50GB+ is not one database (that would be too small to mention), it's one single image file.

So ya, SATA III's would help a lot.

It would be out of my reach in terms of money, but just out of curiosity, will any crazy manufacturer/modder build a PCIe SSD for laptop use?

 

That'd be pretty sweet, but I won't be holding my breath... and now you have me wanting it.

 

SATA Revision 3.2 supports SATA software protocols over PCIe hardware interface (known as SATA Express). From 8 Gbps up to 16 Gbps!

Derek is right about the SATA controller though. 7-series chipsets support RAID 0 array with TRIM, but the bottleneck, again, is the SATA 3 Gbps.

 

The P170 would let you run two SATA III drives but it might be worth holding out for haswell, I sure hope it has more ports.
