The SSD Anthology: Understanding SSDs and New Drives from OCZ

Application Launch Times
You know the drill; grab a stop watch and let's see how fast some of these apps run. The first on the list was just how long it takes to boot my application testbed. This is a fully configured machine with over 50GB of applications and data. I started timing as soon as I hit the power button and stopped it as soon as I got to the Windows desktop. Note that around 15 seconds of the boot takes place before the machine ever finishes its POST:
Most of the SSDs perform similarly here and all of them are a good 20 - 30% faster than the WD VelociRaptor.
I tried launching Adobe Photoshop CS4:
Not all applications will launch faster than a VelociRaptor on a SSD, but let's not forget that the VelociRaptor is the world's fastest consumer desktop hard drive. Put one of these SSDs in a notebook and you'll completely redefine the word performance.

It's referred to as "discard" in the kernel functions.It works very well w/ SSD's that support TRIM, like fusion-io's drives.

This is the best review I've read in a very long time.Thank you very much!

Great in depth article on flash based SSDs. I'm waiting for PRAM though.orclordrh - Tuesday, March 24, 2009 - link
Very illuminating article, very well written and researched. It made me glad that I didn't pull the trigger on an SSD for my I7 machine and regret not buying OCZ memory! I'm interested in adding an SSD as the scratch disk for Photoshop CS4 to use. I don't really launch applications very often, say once a week on the weekly reboot and keep 6-8 apps open at all times. I have 12GB of memory for that. The benchmarks were very interesting, but what sort of activity does Photoshop scratch usage create? Large files or random writes? What type of SSD would be most cost effective here?An SSD does sound better than a SSD!

wait for ddr3 to enter the mainstream and buy loads of memory.use a ramdisk for your adobe scratch area. much faster than ssd and no wear to worry about (not that you would worry that much with modern ssds anyway).

there is also a paid for and more feature rich ramdisk out there. can't remember the name

I'll have to check when I get home, but I believe the recommended size for the scratch disk is upwards of 10GB. So would need a motherboard that supports a LOT of RAM to give enough to main memory plus a scratch disk.strikeback03 - Wednesday, March 25, 2009 - link
I was wondering the same thing. I'd guess it would be a lot of writing/erasing, so an SSD might not be the best from a longevity standpoint, but if your system is hitting the scratch disk often then the speed might make it worthwhile.mikepers - Tuesday, March 24, 2009 - link
Anand,I wanted to compliment you on what I think was an excellent article. This is the type of thing I really have always liked from Anandtech. The detailed background, the technical reasons for the issues and then a thorough review of the current state of things.
I just finished upgrading my desktop. The only remaining item I wanted to replace was the hard disk. I had been thinking about getting a Velociraptor but instead I just ordered a 60GB Vertex from Newegg.
Thanks again for all the work.

That sure was a lot to take in! Fantastic article though, it has really opened my eyes to the possibilities that Solid State Drives provide. Probably wont be buying one in the immediate future given the so-called depression and such things, but i will certainly keep up with SSD progress.Thanks again for your fantastic articles - im sure im not the only one who really appreciates them :)

Hey Anand, I just finished reading through this whole article and I'm very impressed with the thoroughness and how informative it was.You just acquired a new regular reader.
