How much extra storage should you build into your Sockle?
Start with 512 GB? Go right away for 2TB?
Is there an economy of scale in buying bigger SSD disks?
|Samsung T5 512GB||196$||0.382$/GB|
|Samsung T5 1TB||398$||0.388$/GB|
|Samsung T5 2TB||798$||0.389$/GB|
Conclusion: NO. The price per GB is +- the same for these common sizes of disks (price of Sept 2017).
Do the prices of SSDs drop with time (Moore’s Law)?
I expected this answer to be ‘YES’, because that was the impression I had. But it appears that in the last years, this trend has stagnated for SSD disks. Look at the price of 512GB internal SSD disks for the last 2 years:
If anything, it went slightly up. So should you wait to buy an SSD disk? No. Prices don’t really drop.
