Rack mounted servers still need to access disk space and the faster the better.
|
|
|
|

Still don't get it : What matters is the user access time to the "cloud" server, which is by magnitude greater than the server disk space access time, so where is the benefit (from the user point of view) ?
Note: I might have a complete false image of how accessing remote data is working, so if this seems to be the case, feel free to send me to Google school first

There is still a difference in the access time between fixed hard disks and SSD. So, no matter what the "cloud access" time is, this difference is definitely going to add to the final equation.

"The Cloud" is not some mystical, magical fairyland where data with little wings flit around waiting to be accessed. It must exist in a physical form, at meatspace coordinates, and be connected to a physical network. Solid state drive technology is a good choice for that physical form. And even if your data is off holidaying on The Cloud, there is still a great deal of local storage that MUST occur, including the operating system, virtual memory, etc. Again, solid state drive technology is a good choice.

Shameel is right, but it's bad for the server as well: because a hard disk read is an physical process, the thread locks until it is complete, and no other threads can get accesses serviced until the HDD is finished. The use of an SSD means that one read doesn't have to block another (or at least not for so long) so the actual throughput of the server improves. Better server performance when loaded equals better user experience regardless of any cloud latency.

Ever noticed how the disk performance drops if you start e.g. copying multiple files at the same time?
if you have more (parallel) requests on the disk the access speed drops. if you have faster drive then the impact of such things gets reduced.

An end user accessing data from cloud storage may not see too much of a benefit, as you say, but a cloud based application (eg CodeProject Workspaces) that has the entire application, caching and database on hosted servers will always benefit from have its data storage on fast disks.

Imagine a service running on the cloud that needs to constantly access data - fast SSDs will be a major perf boost here.

The benefit isn't so much for a single user; but for multiple concurrent users. In IO bound workloads going to SSD storage can get a 5-10x reduction in server count/rackspace used (more of the latter since a server with a pair of mirrored SSDs is a lot smaller than one with a large raid for speed not capacity).

Most cloud servers actually use stripped SSD arrays.
|
|
|
|
|
power consumption and heat generation are much lower on SSDs. which might be a factor if you're using a lot of drives.

There was an absolutely great article The Insider reported on regarding SSD's. I'm caught up in fixing broken tests at the moment, otherwise I'd try and find it for you.

If it is the same that comes in my mind, I think I've read it.

If it's the one I remember (the vendor who was upgrading MySpace) it was dropped into the memory hole years ago in favor of newer case studies.

Then scroll to the bottom for the comments.
I have noted a couple of points about this 'Journalist' (and I am using the term journalist in a quite inaccurate way).

The torygragh does not beleive there are any other web sites so naturally they redirect everything back, just like Vorbis's head.
