Intel 320 Series vs. OCZ Vertex 2 (vs. Apple)

Actually this post should be called NO OCZ NO or something like that…

I already wrote about the OCZ Vertex 2 E once or twice with somewhat mixed feelings. Now after 6 months with the first one, and 3 months with the second one, I wouldn’t recommend buying any of these again. Well, at least not if you’re using Apple.

60Gb OCZ Vertex 2 E in my Mac Mini (6 Months old):

  • huge loss in performance (maybe due to the lack of TRIM in OSX?)
  • sometimes the mini won’t fall asleep or just wakes up again

120Gb OCZ Vertex 2 E in my MacBook Pro (10 weeks old):

  • performance is still good
  • suspend2disk doesn’t work. Known bug. OSX will crash. OCZ promised to fix it - but didn’t!
  • sleep and direct wake-up results in the SSD not being recognized for ~10 minutes!!! No booting possible!

Most of the issues with OCZ’s SSDs seem to be sleep/hibernate related and from what I’ve heard do mostly affect Apple products, but their crappy support prevents me from buying any of their products again. They promised to release a firmware upgrade which fixes suspend2disk, but they did not. They closed the thread in their forums and don’t even respond to requests via eMail. But hey! At least they release the OCZ Vertex 3 - so you possibly get all these bugs fixed for just 180€!

All these issues and their non-responding support made me replace the Vertex with the new Intel 320 Series SSD. They might be slower according to their specs, but performance isn’t everything

Which leads me to the next part of this post…

The Intel 320 120Gb SSD! I installed this one in my MacBook Pro last week and what shall I say? After one week everything is great. I’m not talking about pure performance. I didn’t NOTE any difference in real life performance, but just in case… here is a simple sequential performance check:

The Intel is a tad slower in pure sequential write performance, which is a bit disappointing considering it’s one generation newer than the Vertex 2… But, now to the important stuff

  * Suspend2Disk: works
  * Closing and directly opening the MBP: works
  * Support: Well... it's Intel. I don't expect it to be any better than OCZ's.
  * The good feeling of reliability: works

I haven’t received any negative reports from friends about the Intel X25-M  (the 320 Series predecessor) nor have I found much on the Interwebs… so I’m much happier with the Intel now…
