RAID0 to speed Lightroom [was: opinion on this AS-SSD result]

Gents: Need your opinion on this result.

From your experience, will I get 1:1 benefit if I add 1 or 2 more 240GB drives into the RAID?
If not, I'm thinking I should just double my RAM instead.

My need is to make Lightroom able to generate 100% preview as fast as possible.


Thanks in advance!

Funny.

Drives are 2x 240GB Sandisk Pro.
Doubled every mark, going from 1 to 2 drives.
Just wondering if I'd get same spees gain if I add 1 or 2 more into the RAID0

You won't because your chipset only has two SATA 6Gbps ports -- additional drives would run at 3Gbps. The real question is, what's the bottleneck in Lightroom? It's not necessarily the SSDs as it might as well be the CPU if the preview generation process is single-threaded. Besides, RAIDing SSDs only increases throughput, it does nothing to improve latencies, which may be part of the big picture here.

IME, so far it has boosted catalog imports and reads and improved 1:1 preview generation.

I'm also thinking to create separate catalogs to every job, just to limit the size of each catalog.

CPU is only a 2500K clocked @4.5GHz. RAM is 16GB.
I know I could benefit from going with an i7 (HT) and by doubling the RAM.
Only reason why I added more SSD was because I was running out of space on a single drive (for temporary work, permanent storage is in a Synology NAS).

So if I add more drives on SATA3G, the entire RAID would operate slower?
Bummer...
 
Maximum throughput on Z77 is around 1,200MBps; an PCIe3.0 LSI controller may be in your future.

Socio: Thanks. They're fast but probably tiny (480GB) compared to your SAS RAID.
What kind is it, Dell Perc?
