Hi everyone
So the thought is to add a 3rd (or 4th) Momentus XT drive/s to the array to see what sort of performance gains are to be had with the onboard NAND Flash that these drive contain running in raid 0,1 or 5.....Here's the glitch! I've just found some XT 250 Gb models for 35 quid delivered
which means I can grab 4 of these cheaper then 2 of the 500Gb units (I already have two of the 500s)....the only hardware difference is 16mg cache against 32 on the higher capacity units.
I'm reading a lot of "Cache only matters with slower drives and IDE" ....Anyone have any definitive idea?..... I've got a Highpoint-640 raid card arriving tomorrow and can't make up my mind whether to get 16 or 32cache drives, so its......
1) 4x250/7200 16mb cache-total...1TB with 64mb cache and 16 gb NAND Flash or
2) 4x500/7200 32mb cache-total...2TB with 128mb cache and 16gb NAND Flash.....Mmmmmmmmmmmmmmmm!
