Fusion-io inside video-sharing site

Elgato launches Thunderbolt SSD
Editor:- March 9,
2012 - Elgato
an external SSD for the Mac market with a
interface (10Gbps) and upto 240GB capacity.
comments:- the company says - "The
Thunderbolt SSD is the fastest single-drive storage solution for your Mac."
since I couldn't find any performance data in their datasheet - I'm unable to
comment on that claim. Elgato's product description does reassure us, however
that it comes in a good looking rock-solid metal enclosure. Oh well - that's a
relief to know. And it's all the significant info we need to know about any new
SSD before buying it. I must have been wasting my time for the past 20 years
worrying about that other stuff.
This is just another example of
sloppy consumer technical marketing. I'm so glad that I leave consumer SSD
news to other sites. But it's amusing to take a peek now and then.
Drobo's new SSD ASAP uses SAS SSDs from OCZ

"Just like larger organisations, SMEs should be able to
afford and enjoy the benefits of SSD technology and performance," said Tom Buiocchi,
CEO of Drobo. "For the best capacity and performance, our unique
data-aware tiering allows customers to easily and affordably add SSDs to the
same Drobo environment that already has high-capacity traditional disk drives."

NVSL paper discusses kernel adaptations to unfetter fast SSDs
March 8, 2012 - a recent white paper -
Safe, User Space Access to Fast SSDs (pdf) - published by academics at
Volatile Systems Lab) at UCSD - discusses techniques for reducing kernel
associated overheads in the filesystem by an order of magnitude without removing
security and file permissions.
The authors say - "Our intent is
that this new architecture be the default mechanism for file access rather than
a specialized interface for highperformance applications. To make it feasible
for all applications running on a system to use the interface, Moneta-D supports
a large number of virtual channels. This decision has forced us to minimize the
cost of virtualization."
EMC arrays will have WD SAS SSDs inside

comments:- after more than a year of waiting -
WD said this week
that it has obtained all required regulatory approvals for its acquisition of
HGST which will close this week. That will beef up

be disclosed afterwards.
3 years later:- in 2015 we learned
that no storage company was too big to be acquired when EMC itself joined the

and architectures are required - because traditional methods can negatively
impact performance - or - as in the case of RAID - don't always work.
"RAID is configured for
HDDs that fail
infrequently and randomly. SSDs
fail rarely as well, but fail predictably" says the author Jim Handy -
who warns that "SSDs in the same RAID and given similar workloads can be
expected to wear
out at about the same time."
He examines in detail one of the
many new approaches to high availability enterprise SSD design - that's used in

|SSDs are complex devices and there's a
lot of mysterious behavior which isn't fully revealed by
vendor's product datasheets and whitepapers. Underlying all the important
aspects of SSD behavior are
which arise from the intrinsic technologies and architecture inside the SSD.

SSDs impact the business of SAS SSD makers?
In the long term I think it will reduce the market size for SAS SSDs
because the new types of SSDs will provide faster throughput and lower latency -
