You're on a budget. You want to know if it'd be better to stripe a couple of smaller SSDs or simply buy one larger performance-oriented drive. Today we're comparing one, two, and four 30 GB Kingston SSDNow V drives to Zalman’s new 128 GB N-series SSD.

Benchmark Results: 512 KB Random Reads/Writes

Testing random reads and writes with a block size of 512 KB is an important scenario, as average file sizes have been increasing over time.

Random 512 KB reads still happen faster on the Zalman N-series SSD than on any of the two RAID setups based on the 30 GB SSDs.

The same results apply to 512 KB random writes.
