My existing laptop is a Dell Inspiron 15R, (N5010) with a Core i3, 8 GB memory and a 500 GB 7200 RPM HDD (I think SATA2), bough back in late 2010. Win 7 x64. I use it mainly for Adobe Lightroom, and the usual mail & web. No gaming or anything. Lightroom handles a large bunch of RAW files, each ~25MB in size. HDD Space is only partly an issue, as although the current HDD is full of photos, I push everything older than 12 months to a NAS. Space is tight, but manageable.
So I've looked at Pricespy, and see I have a choice of 64 GB SSD cache with 5400 RPM spindles, or 32 GB on 7200 RPM spindles.
I'd like to upgrade to a 1TB hybrid drive, but I'm not sure if the performance hit of going to a slower spindle for photography work would offset any gains made by the SSD cache. Otherwise, a 7200 RPM drive, with its smaller cache and also smaller capacity, at only 750 GB.
I imagine scrolling in LR through a catalogue of photos could tax the slower drive, but I'm not sure how significantly.
Has anyone experience or thoughts about this?
