Western Digital releases range of SSDs

Western Digital releases range of SSDs

Western Digital has started shipping a new range of WD-branded SSDs following its acquisition of SiliconSystems in March 2009.

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.

If it's not on the roadmap, would that mean they plan on decreasing the capacities?

When you say "released", d'you mean "I can go and buy one", or "I might be able to go and buy one in eighteen months, so long as they don't get bored with the idea in the meantime?"

Interesting that they are releasing EIDE SSDs, that would certainly suggest that they were going after the embedded market.

I never understood why the SSD lifespan is never mentioned. I think it's 2 years... so 100$ per year for few GB... really not worth it by extremes.

Hi Tim do you know which memory controllers these WD SSD's use? Indilinix, Samsung or the woeful JMicrons?

Many thanks

Um... OCZ SSD's have been doing that for quite a long time now, since the 'solid' series onwards

Also, forum link at the end of the article doesn't point to this thread ;)

I admit I'm surprised by this, i expected their first SSD to be a Raptor drive since it'd make sense

Because as far as I understand, those limitations have been largely overcome by now and modern drives have far larger write limits.

Not if its slower than a mechanical raptor... :)

Indilinx controllers are in the second generation of SSD's such as the new Corsair P256 and G.Skill Falcons.

I think I will wait for the third generation of SSD's before purchasing as they are still too expensive for me at the moment.
When they reach £1 per Gb I'll reconsider.

Good to see more players in the market though as it will increase competition, increase speeds and eventually bring prices down.
