SSHD - Performance comparison with HDD and SSD

   Information

We had several discussions regarding the benefits and performance of SSHDs. But since nobody had any real data, I decided to order a SSHD when a reasonably priced model was on sale at Newegg. I ran comparison tests with a HDD and a SSD and the details are below.

I have removed the original posting from here because it was polluted with Adware. But you can still access it from my One Drive - without Adware. I don't want my good name associated with advertisement for questionable products.

That's what I said at thje end of my evaluation. One day I will image the OS on the SSHD and compare it to my SSD. But as I said, that is a bigger job because I will have to physically change disks in my laptop (that's what I would use because I do not fancy to crawl under my desk where my desktop is).

Any other useful comments?

My experience with an SSHD was somewhat different. When I first installed it in my notebook, boot times didn't improve much but program loading was much faster and access of large blocks of data by a couple of programs (MediaMonkey and caliber) improved quite a bit. However, mostly because I kept deleting and adding large blocks of data in a short period of time, the NAND in the SSHD apparently became overwhelmed and everything slowed back down to HDD levels.

This is not to say SSHDs are not any good. They just aren't for everyone. If one uses a limited number of programs and pretty much does the same thing every time they use the computer, then they will see a dramatic improvement. I my case, I was better off getting an SSD.

LF, this is valuable input. I was sure that the SSHD is going to behave differently in different situations.

After the holidays I am going to image the OS from my laptop's OCZ Vertex III to the SSHD. Then I am going to run some benchmarks on the Vertex first. Then I switch the disks and rerun the same benchmarks on the SSHD.

Problem is that the OS does not register a lot of performance data. Apart from the boot and shutdown times in Events 100 and 200 in the Event Viewer, I know no other performance data that is recorded. Maybe I can find some benchmark program for the job.

The problem with benchmarks is they do not always reflect real use performance. Reports of seat of the pants performance are far more meaningful. Benchmarks are useful, however, as an indicator of how performance later compares to performance earlier; a drop in the benchmark provides a tangible indicator of when something is cause a drop in performance; basically, a diagnostic tool..

I think anything you measure is going to be a bit artifical because the next guy may have a completely different setup and different requirements. I just like to provide those numbers for whatever they are worth - it's better than armwaving.
