To Branden and Tulx both: cool! Any idea why it works? Is Garbage Collection good enough to compensate? I'm pretty sure that if the TRIM / RAID issue had been overcome I would have read about it.
i don't know enough about the inner workings of RAID or TRIM or garbage collection to be able to speculate why it works. i had no idea myself how RAID 0, JBOD, and leaving them as individual drives would compare so i benchmarked all scenarios, turns out RAID 0 was fastest so i stuck with it.
First - The effectiveness of CG is highly dependent on three factors:
(a) The Controller in the SSD, The marvel being the worst.
(b) The amount of free space
(c) How the user interface (uses) the SSD
Some comments on raid0
- Raid0 improves sequencial read/writes around 50/60% as branden pointed out on his. This provides a big benifit when working with large files. Does very little to improve small file random read/writes and no improvement in access time. These two factors are the most important in boot time and program load. - branden, how much did these two factor improve on your raid0 setup.
My 2 Cents:
- Raid0 may be the choice when you have a pair of larger capacity drives and can leave a fair amount unused. My personal oppion is that with 2 very small drives, Not recommended, unless you plan on using them as a data drive and leave 20% of the avalable space free. (2 x 16 - .2 x 32 = 26 gigs Dec, so really less - TOO SMALLL for a boot drive + no trim) Vs a 16 - 10% + a 30 - 10% as two seperate drives for data with trim.
