Thread: Solid State HDD's

big differences between brands....

do your homework

PS i didn't bother on my latest box

Brilliant. I use a 120GB one as my primary system and applications disk and keep the data on regular disks. Boot time is massively faster than anything with regular platter disks. Also my CAD package loads super-fast.

I am using an OCZ Vertex something or other which hasn't given any trouble at all for the last year since installing it.

just did a test in the workshop

the 128g ocz vertex 3 will load 64bit windows 7 in 19 seconds on a sata iii port

a western digital black 1tb sata iii 64mb cache 7200 rpm drive takes 40 seconds to do the same load

a seagate 7200.12 takes 39 seconds

the ssd is about twice the price of the 1tb drives (on average)

Hey Vlad,, I thought we'd already covered SSD's??
maybe the great database crash of '11 deleted it,,,
there was a great link to a test of the fastest SSD's around,,

Have our lives got so time precious that 20 seconds is an issue???

Dear me, we have got ourselves into bad shape.

Put the kettle on, hit the button.
Make a coffee and then sit at the PC ;-)
Much more relaxing!

I had a nettop running on a Corsair SSD. After 11 months the drive died, no longer recognised by the motherboard. It took 3 months for the distributor to give me a replacement, and the new drive is labelled "refurbished". Whilst that may be a functional replacement, I do not regard it as a replacement on an equal basis, because a refurbished drive has a far lower $ value should I choose to sell it.

So, the drive was quick, and used less power. But it failed after 11 months. I have used hundreds of disk drives, starting with 10MB drives in the mid 80's, through large RAID installations through to the current crop of 2TB+ portable drives. In all that time I have had only a couple of unexplained catastrophic drive failures (lost all data without warning). I have owned one SSD, and it failed catastrophically in 11 months.

I did some investigating, just out of interest. I do not recall where the information was located, but the warranty return rate on laptops with SSD's was far higher (two or three times) than for those traditional drives.

My personal conclusion is that if the 4W of power saving, or the few seconds of Windows load time is important, then spend the money and get a SSD. But make sure it's completely backed up, preferably in a "one button restore" manner so that when/if it fails you don't lose either data or time. Either that or use several SSD's in a RAID (protection not performance) so that the failed drive will not impact you too much. Of course all data should be backed up, but most people don't bother because generally speaking disc drives are fairly reliable. SSD's just don't seem to be.

By the way, the replacement "refurbushed" SSD is still on my desk. The time taken from un-sleeping my PC is not reduced enough by an SSD to warrant the effort, and I rebuilt the nettop with a traditional drive because I got tired of waiting for the replacement drive.....

Tombie I came to the same conclusion as you. Cheers all

OK, I've just found a use for my SSD where its performance can help but any reliability issues should not cause problems.

I've built a new PC using a motherboard based on the Intel Z68 chipset. This chipset uses Intels "Smart Response Technology", which allows a SSD to be used as a cache. There are two modes of operation, the "enhanced" mode in which data is simultaneously written to the SSD and the normal disk, and "maximised" in which the SSD caches reads and writes, and the writes are sync'ed to the normal drive intermittently.

I have configured a mirrored pair of 1TB hard drives, providing data protection (no performance increase) and then used the SSD with Intels SRT in enhanced mode to provide a cache from which data is read.

The system now automatically caches any reads to the SSD, so that future reads are far quicker (being SSD speed rather than spinner speed), but because all writes are made to both spinner and SSD, the write performance is not improved (writes are normally fairly minimal compared to reads) but a failure of the SSD will not kill the system.

And yes, it seem to work. Windows 7 load time is much reduced, opening programs is far quicker, and the system feels faster. All at minimal risk, and all using a 32Gb SSD that I already had.

So, whilst I still would not make myself dependent on an SSD, I have found a way to utilise the SSD performance advantage without (hopefully) creating a reliability issue. Obviously a mirrored pair of SSD's rather than spinners+SRT would give better performance, but for the far lower cost of a 32Gb or 64Gb SSD it would seem that with SRT we can have almost the best of both worlds......
