I recently transplanted a small PATA SSD into my SD 722. Here are the reasoning "after the fact" for me.
First of all, why change. After all, if it a´int broke, don´t fix it. Well, my machine has reached a certain age and why not? Good time of the year sort of right now. ( critique , not really that well argued )
The options for me was either a PATA SSD ( there are a few available ) or new harddisk.
Price -- SSD about 4 times as expensive, not very much money though as both came below the cost radar
Capacity -- about same, never had problems with 32G in my machine, so 64 seems reasonable
Power consumption -- about same for the total system
Performance -- both good enough
Weight, other factors -- both good enough
Reliability -- probably compareable in my usage. The harddisc has never had a problem. According to the numbers, as far as I can understand, I can expect the SSD to hold the next 10 years. From the manufacturer spec: Write endurance 80years@10GBytes write and erase per day at 128GB and 10 years data retention.
So basically, just for the fun of it. Will report back if things change.
My choice was one that a distributor around here happened to have in store:
MICROSTORAGE 1.8" 64GB SSD PATA MLC
MSD-PA18.1-064MJ
Had to pad it up with some extra foam as it is smaller than the 2,5" harddisc.
Thinking right now if I want to speed up one of my old laptops with a SSD. Not quite certain that it is worth the effort, might want to have a new instead ....
