I use several different computers to test ERDAS IMAGINE for speed and scalability. Hexagon Geospatial has a working agreement with HP, so we get some HP equipment before its release to the market, and then use if for several years in processing and testing. <br /><br />For laptops, the biggest concern is disk speed and RAM. You should have at least a 7800RPM disk. This is not related to the software, but to the image data stored on disk. <br /><br />For RAM, you need a minimum of 8GB for OK performance. But, you should strongly consider more RAM as the OS will take up a lot of that RAM. Also, laptops and low end desktops do not have sophisticated hard disk controllers, so they use the main CPU and RAM for this task.... thus cutting into your memory usage and processing power. <br /><br />The key to a good hardware value, a balanced approach. More than 8GB RAM with a 5400RPM disk is not a good idea. Likewise, less than 8GB RAM with a 7800RPM disk is not a good idea. Try an HP laptop with 16GB RAM and a 7800RPM disk with a small SSD for swap space (virtual memory). I think you’ll like that. <br />Paulhttps://www.blogger.com/profile/13894940986452821719noreply@blogger.comtag:blogger.com,1999:blog-1883623975517863992.post-23566089937911359362014-12-22T10:19:55.214-05:002014-12-22T10:19:55.214-05:00CAN i use a laptop with high components CAN i use a laptop with high components Anonymoushttps://www.blogger.com/profile/10832095134929460213noreply@blogger.comtag:blogger.com,1999:blog-1883623975517863992.post-83739479463104993552013-05-29T11:31:37.111-04:002013-05-29T11:31:37.111-04:00Hello Timo, somehow this post got trapped in bit p...Hello Timo, somehow this post got trapped in bit purgatory. I agree with your comments. I have started playing with SSDs and they sure hold a lot of promise. We have been researching with some 64-bit code of ERDAS IMAGINE. This is part of the work we have been doing for some time. Some remove sensing workflows will benefit quite a bit from expanded RAM, some not so much. We are identifying the highest value workflows in our research.

SSD's are fast and in case data is small enough to put in a SSD you see that performance is so good that disk is no longer limitation. So you even can run multiple processes simultaneously without losing any time as jobs were run individually.<br /><br />2) When using big internal SATA drives consider using some SATA controller cards instead of just using the motherboard connectors. In motherboard disk control is in CPU and OS but in controller cards disk is controlled via this card. That in generally boosts disk performance in long run when disk control is given to some deticated device.<br /><br />3) As you comment external drives are wast of time. If still external drives are mandatory as they sometimes are make sure that connector is something else than USB2 - so in practise USB3, eSATA or FireWire - with that you can save a lot if external drive is only option available.<br /><br />timo<br /><br />ps. Hint for using more than 8gb of RAM is my next investment. I thought that 8Gb is enough as I never manage to consume it all but if that helps I will try. RAM is not that expensive nowdays.Anonymoushttps://www.blogger.com/profile/09614540707883127323noreply@blogger.comtag:blogger.com,1999:blog-1883623975517863992.post-7471834789401416592013-04-29T06:17:21.667-04:002013-04-29T06:17:21.667-04:00This is my favourite topic too.
