Imation SSD versus Western Digital SATA: Performance test results

In today's shootout between Imation Pro 7000 solid state drives and Western Digital's VelociRaptor SATA disk drive (see "Product review: High price makes high-speed Imation SSDs a tough sell"), Mario Apicella finds that SSD is indeed the fastest storage that lots of money can buy.

In today's shootout between Imation Pro 7000 solid state drives and Western Digital's VelociRaptor SATA disk drive (see "Product review: High price makes high-speed Imation SSDs a tough sell"), Mario Apicella finds that SSD is indeed the fastest storage that lots of money can buy. Given the whopping superiority of the Imation SSDs in read I/O and read transfer rates, their advantages for search-intensive applications may help dull the pain of the price premium ($550 for a 16GB model, $1,700 for 64GB). But for write-heavier workloads, $300 for a 300GB VelociRaptor is a lot easier to swallow. See the results of Mario's speed tests below.
