Just two and a half months after purchasing SSD manufacturer SiliconSystems
, Western Digital has announced a whole range of SSDs under the SiliconDrive III brand.
The SiliconDrive III series will be available in 2.5in and 1.8in form factors with either a SATA or EIDE interface and come in a variety of capacities from 30GB to 120GB.
The 2.5in models come in 30GB, 60GB, 90GB and 120GB capacities, which is a strange step since most manufacturers jump straight from 64GB (approx 60GB formatted) to 128GB (120GB). Intel is the only other SSD manufacturer to offer something with a similar capacity with its 80GB X25-M drive.
Meanwhile, the 1.8in SiliconDrive III is currently only available in 30GB and 60GB capacities - the company doesn't detail plans to increase these capacities in the near future, but we presume that's on the roadmap.
In terms of performance, Western Digital claims the new drives feature sustained read speeds of 100MB/sec and writes of 80MB/sec for the SATA drives and 85MB/sec and 60MB/sec for reads and writes respectively on the EIDE models. This is quite a bit down on the ballpark speeds most high-performance SSDs are hitting today, but what makes it difficult to judge is the fact that Western Digital hasn't released pricing for these drives yet.
The company does, however, say that the drives are aimed at "network-communications, industrial, embedded computing, medical, military and aerospace markets," which suggests they might be more expensive than typical consumer-orientated SSDs.
