The spare one has a faster (and smaller) disk. WinSat numbers:
Main T500: Average Read Time with Sequential Writes 22.161 ms Average Read Time with Random Writes 20.880 ms Latency: 95th Percentile 123.878 ms Spare T500: Average Read Time with Sequential Writes 7.053 ms Average Read Time with Random Writes 12.511 ms Latency: 95th Percentile 57.014 ms I imaged the hard file from my main machine and copied that image to the spare. I also moved my 8 GB RAM over so the RAM size would be the same and the results are: Main T500, slower disk: 00:01:48 corba 00:02:54 demos 00:10:32 docs 00:05:59 hotspot 00:07:50 images 00:01:16 jaxp 00:03:00 jaxws 00:29:35 jdk 00:01:36 langtools 00:00:43 nashorn 01:05:20 TOTAL Spare T500, faster disk: 00:03:22 corba // slower 00:02:31 demos 00:04:44 docs // much faster 00:17:09 hotspot // much slower 00:03:35 images // much faster 00:01:31 jaxp 00:02:36 jaxws 00:21:41 jdk // faster 00:01:19 langtools 00:01:06 nashorn 00:59:41 TOTAL So the disk speed didn't make much of a difference Note the these times are about 0.5 hrs better than before. I had removed a few programs and files to free up space prior to being able to create an image that would fit onto the smaller 250 GB disk. The only thing related that was removed was VS2011 Express. Pete p.s. Thanks to all of the others that replied. Hopefully I'll get to your emails later today. > > -Dmitry > > > On 2013-08-09 20:25, Pete Brunet wrote: >> Any suggestions for SSDs?
