Got a chance to play with some SSDs. Ran some Xbench benchmarks and some general observations. One of the SSDs was crazy fast! the contenders are: 1) Baseline: apple 5400rpm 250GB hard drive (fujitsu) 2) Apple 128GB SSD (Samsung MLC) 3) Intel X25-M 80GB SSD (MLC) 4) Intel X25-E 32GB SSD (SLC) the machine is a late 2008 15" macbook pro with 2.8 processor and 4gb ram. For the tests I ran xbench 3 times for just the disk benchmark. I then averaged the results for the final score. Click on the below graph for the full size version As you can see from the results the Apple SSD is not really that much faster than a hard drive. In terms of subjective feel, it's a little snappier, but not clearly so. Some rough times: Apple (Fujitsu) HD Boot Time: Approx 1:05 - from power on to desktop Apple (Samsung) SSD Boot Time: Approx 58 sec Apple (Fujitsu) HD Launch Safari - about 3.5 sec, or 2 bounces of the icon on the dock. Apple (Samsung) SSD Launch Safari - about 1.5 sec or 1.5 bounces of the icon on the dock. I'm not sure it's worth $500 to upgrade to the Apple SSD. The Intels, on the other hand, have a clear performance advantage. The X25-M (MLC) 80GB makes the system feel significantly snappier. Boot time was about 50 sec, and safari launch was under a second (less than 1 bounce of the icon on the dock). What blew me away was the Intel X25-E (enterprise) drive. It's SLC, although only 32GB. Boot time was a insane 20 sec! and safari launch was instantaneous. Unfortunatley 32GB is probably too small for any kind of serious use. I see some people are modding their macbooks to replace the optical with a second hard drive. That would be ideal: the Intel X25-E for the system drive along with a second hard drive for data storage. Anyways, thought this community would enjoy seeing the results of high-end SSD testing. Let me know if you have any questions or would like me to run additional tests.
