tl;dr:The most economic value in Gigs per dollar is the TOSHIBA 1TB 2.5″ for $79.99 @ 12.5015627 GBs per $1 USD
I am in the market for 2.5″ SATA HDs, I have a server that insists that 2.5″ is the future, so that is what it holds. I wanted to know what was my best price per gig, so compiled below is a current (time of post) comparison with 2.5 SATA HDs found on Newegg.com. The reason for compiling this table was to determine the best value for space per dollar. Since most of these drives are 5.4k rpm, it is understood that the whole reason for these drives is simply storage. This makes many of the other speed factors become next to negligible. I plan on populating a server with these small and cheep drives, and running in some form of RAID to help boost the performance a tad.
|Storage (GB)||Price $ (USD)||1 GB/$1 USD|
You will notice that there is a 750 GB drive which has a better rating, the only reason for this is because it is refurbished, and has a limit to 5 per customer. Not exactly a standard product or pricing. Actual pricing starts at about $10 higher for the 750 GB models, which is also listed.
