Though mine was a bit pricey: I went for the Intel X25-E 32GB. The OS and homedir are on it; Large datasets go on various Samsung SpinPoint 1TB F3 drives I've installed as well. The system is already more than a year old, and the free space is < 20%, which, I am assuming, means I've already filled the disk (due to deletes and the SSD wear-leveling algorithms) and already doing erases, and....the performance is still nothing short of AMAZING - sub-1ms seek time is a great thing when you scan the filesystem etc. It just feels as if Disk I/O is no longer my bottleneck (and the CPU is a Quad Core AMD PhenomII 955 with 8GB RAM...). Of course - I don't use swap. Performance after > 1 year as mentioned: # hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 722 MB in 3.00 seconds = 240.27 MB/sec As always, YMMV :) -- Shimi
