My crazy SSD drive performances

My crazy SSD drive performances

I have three high end PCs. Each with an SSD.  One is an OCZ-Summit. Another is an Intel-25M and the newest is an OCZ-Vertex 3.

As a quickie benchmark, I copy the Winsxs directory (from the \Windows directory) back onto the drive and just look at the megabytes per second.

And wow, big differences.

The OCZ-Summit gets around 10 MB/sec.

The Intel-25M gets around 40 MB/sec.

And the OCZ-Vertex 3 gets about 110MB/sec.

When copying big amounts of stuff (or compiling big amounts of stuff) this is very noticeable.

I haven’t figured out what is making such a difference.  The PC with the OCZ-Summit is faster than the one with the Intel-25M. (Core I7-965 vs. an I7-920).  So is it the drive? The controller? Or something else?

The OCZ-Vertex 3 is on a SATA 6.0G controller and is a brand new drive so I’d expect it to be faster.  But 11X faster than the Summit?

Any thoughts?

An SSD isn't going to be any safer than a platter.  Both have finite lives.

Genuine long term storage will also mean minimum access/use.

Then you'll only have to worry about still having the hardware and/or OS to access it....

Hmm...why was I under the impression that the other big advantage to a SSD was that they didn't have any moving parts and had incredibly long, nigh on indestructible, life spans? I could have sworn I read that somewhere when I first heard about SSD's a few years ago?

No moving parts means immunity to high G impact damage [reasonably], and no 'mechanical' deterioration.....but finite 'rewrites' means there will come a day when an SSD will simply write no more....;)

Well, finite writes isn't a major factor in storage.. since storage is something you typically write once and then read over and over later (like installing games or storing video/picture data.

The read errors on SSD are typically very, very low. Mean Time Between Failures are theoretically somewhere in the 100+ years range, and the actual real world rate of failure on SSD is very low (Intel's drives are reported at 0.5% a year, which is decades of fairly safe storage). Standard plated HDD can have a fairly low rate as well, but getting into the 2 TB storage range it gets pretty high (over 9% on one of Western Digital's drives, that's only 10 years before you are almost guaranteed a failed drive).

 

Yeah, SSD isn't "perfect" and "immune to failure", but it's got a better chance at living long enough that you'll want to have newer technology than some of the other drives out there. Especially the big storage drives.

 

Edit: Oh, also.. most flash SSDs that are built today have write times measured in decades. Personally for me, if it lasts longer than 10 years, it'll likely be replaced by new technology anyways, or it was something I don't need anymore.

When I think back to 10 years ago, there's very little data that I still need from back then. On a business scale, maybe it's not as good. But on a personal level, I'll likely not run into problems with writes or reads, as long as the drive is dependable itself.

i would like to mention HDD´s like the WD Velociraptor 10k rpm and they run also via SATA 6G these things are big + fast and low on price and in my eyes a real option for everyone who does not want to spend 150-200USD on a 60gig drive its the best thing i have found that works nicely together with an SSD
But like with the SSD´s you will need the right MB to get the performance

From what I've read, Velociraptors are noisy because of the increased drive speed and the vibrations that speed causes. Though if you take them out of the heatsink they're encased in, and suspend them using elastic or something similar ( I use 3mm bungee cord to suspend my drives) it makes it nice and quiet. Unfortunately taking it out of the heatsink invalidates the warranty.

Starcandy bungee cord sounds nice but you can buy vibration absorbers for most cases these days or the case already comes with some screws with rubber absorbers.

Yeah, I've seen plenty of those kinds of things. The problem with them generally tends to be that they don't use a soft enough rubber/silicone to effectively absorb the vibrations.

That's my hard drive suspended with bungee cord, washers and some thumbscrews that came with the case. That puppy's going nowhere, and any vibration doesn't go through the case anymore. Nice and quiet, and it only cost about £2.50 for a metre of the bungee cord off eBay, which came in handy when I discovered the screw holes for my SSD won't accommodate any of the screws I have. ;)

It may sound stupid but the screws you use look exactly like the rubber screws i was talking about earlier only that yours are missing the rubber absorbers and i see no HDD racket. The solution is smart no doubt but IS that HDD hanging sideways ??

Just wanted to pop in and mention...my first Revo the firmware wouldn't update so I RMAed it, the second one will die on me after extended writes...so I'm RMAing it again...

Don't think I'll be buying OCZ again, this is lame.

Yes. Yes it is. Modern HDD have no issue with positioning, and there wasn't enough room in the drive bay to suspend it in a flat position. It's been running like that for a good year and a half now, I think. No problems with it.
