About $3000 worth of Intel --- mainstream SSD's = 240GB space (6 in raid 10) today, 2x to 3x that storage area in 1
year.
Random reads are even easier, provided you don't need more than 500GB or so.
And with something like ZFS + L2ARC you can back your data with large slow iops disks and have cache access to data
withoutrequiring mirrors on the cache ($3k of ssds for that covers 2x the area, then).
