I use mostly OCZ.  I have one RevoDrive and two Vertex 2s.  One little Kingston for a boot drive.  Format them to ext4, then use the "commit=xxx" mount option to slow down the journal writing.  Very fast and no reliability problems here.

Hi dibl,

a Kingston for boot? How do you do this?

[dibl]

When I built my desktop rig in 2010, I got an OCZ RevoDrive SSD, which is a PCI bus device (not SATA).  But when I tried to install the OS, I learned my Asus P6X58D-E motherboard's BIOS cannot see a bootable device on the PCI bus.  (A known issue if I had done the research first).  So the installer could not install grub and the boot files there.


However, the RevoDrive is seen by fdisk and any OS as a hard drive.  The problem is only with the BIOS.


To do the initial installation, I grabbed an old 40GB hdd and installed /boot on that, and the rest of the OS on the RevoDrive 120GB SSD.  That got my system booting and running.


Then, I bought a cheap 16GB Kingston SATA SSD, made a small partition for /boot, and made the rest of it swap.  I formatted the small partition ext2.

I copied everything in /boot to the first partition on the Kingston SSD, reinstalled grub to the SSD, made the mount line in /etc/fstab, removed the hdd, and it has been running fine ever since.

Hi dibl,

wow you made that! Thanks first of all for your information. I think I can good contribute by.
In the moment, I have to check whether the MB Asus H81M Plus has Bios or Uefi, so is an up to date one. I do not know, whether the transition phase is in the beginning or already on Uefi....have to find out.

[dibl]

@mylo, I think all the new main boards are UEFI.  If you can tell us how to deal with that, it will be good help for those of us facing the first time on a UEFI board.

Hi dibl,

of course I will share my experiences on that with the community. I have to check on monday price and delivery date and come back!

SSD=good. I'm very happy with my OCZ Vertex2. Make sure to set noatime and discard in fstab. Tom's Hardware do regular SSD comparison tests, and Samsung usually fare well.
On a side note, it's a shame that OCZ have declared bankruptcy and are being bought by Toshiba. http://www.anandtech.com/show/7559/toshiba-acquires-oczs-assets-for-35-million

* maybe OCZ bankrupcy  leads to more quality - nevermind, my old vertex 2 works ok, the new vector 256G works ok - one of my two samsungs 840 pro works without problems, the other 840 pro died silent after 3 Weeks of use
