Western Digital VelociRaptor (1TB) - Spin Me Right Round

Launch SRP: S$429

Results - AS SSD Benchmark

AS SSD Results

AS SSD is a benchmark that uses non-compressible and completely random data. What this means is that the drives using the SF-2281 controller cannot compress the data first, which takes away one of the strong advantages of this controller. Therefore this is a useful benchmark because drives that use the SF-2281 don't gain an upper hand. 

Right from the get-go, we can see that even the fastest mechanical HDDs are no much for today’s SSDs. While sequential read and write performance is still somewhat decent compared to SSDs, the moment we move into smaller data blocks, the figures become ridiculously lop-sided in favor of the SSDs. Nevertheless, the new VelociRaptor drive has showed very significant improvements over the old drive which it replaces. Despite the larger capacity, sequential read and write performance was over 50% better while performance in the 4k, 64 queue depth run was over 30% better in read operations and a whopping 83% faster in write operations.

The Good
Significant performance improvements over old VelociRaptor drive
Reasonable price
The Bad
SSDs are still very much faster
No accessories
