As you may have noticed, I have installed a ICYBOX IB-RD2262 USEb on my MacBook Pro. It contains two 500GB SATA disks. You can either use the “RAID Master” provided tools to create the RAID system or use the Mac OS X native RAID system. The main difference is that, using RAID Master, you’ll only see the rendered RAID disk in “Disk Util” ; whereas you will see both disks and the RAID system if you use the standard OS X configuration.
I wanted to check if there were any performance difference between native OS X configuration and RAID0/SPAN using RAID Master. Maybe using RAID Master, you benefit some hardware RAID system…
I got an ICYBOX IB-RD2262USEb RAID Enclosure for 2.5″ HDDs to plug some of my spare SATA disks into my Mac.
This enclosure has two main benefits. It enables me to plug my external 2.5″ disks using Firewire-800, which is faster and less CPU consuming than USB2, and it enables me to plug the two disks using a single cable. Another nice feature is that is also has an eSATA plug so that I may later connect it to my Synology.
So what I did is plug a Seagate Momentus 5400.6 500GB and Western Digital WD5000BEVT 500GB inside the box. Then use the Firewire-800 cable to connect them to my Mac.
First good new : the Firewire-800 cable gives enough power to bring both disks on. No need for additional power supply.
I just got a Crucial C300 SSD to plug in my Mac. And it came in revision 02 ; but the latest bug free firmware is revision 07.
To upgrade, just go to the Crucial website and get the “C300_FW0006.zip” archive. Unzip and burn the ISO file. Reboot, use ‘alt’ to drop to the boot selector and select the CD drive ; it appears as “Windows”. Let the process find your drive and upgrade the firmware to 06. When done, reboot.
Now, get the “C300_FW0007.zip” archive and replay the previous scenario.
After a few seconds, the SSD has the latest firware installed:
C300-CTFDDAC256MAG : Capacité: 256,06 Go (256 060 514 304 octets) Modèle: C300-CTFDDAC256MAG Révision: 7
So easy! And so nice it works on the Mac!
By default, my MacBook Pro goes into deep sleep (hibernate) mode when I close the lid. This is nice but I have 8GB of RAM and it is quite a slow process. Furthermore, I never went out of battery during a whole sleep process. So I’m going to avoid dumping my whole RAM content to the SSD disk and save of bit of it:
# pmset -a hibernatemode 0 # rm /var/vm/sleepimage
Should I want to re-enable hibernate mode, I’d run
# pmset -a hibernatemode 3
This enables going in sleep mode in 2 seconds, rather than a minute… w00t!
I had issues with my Seagate Momentus 5400.6 500GB… It felt very slow… But it also only had 10% free space left…
It’s been two weeks I’m trying to work on this… Defragmentation, Onyx on the system… Maybe it’s just to full… Thank my Sanyo HD1010 for that… So let’s go for it… upgrading to 8GB of RAM (from stock 4GB) and to TOSHIBA MK1059GSM 1TB.
