  • The main difference between gp2 and gp3, however, is gp3’s decoupling of IOPS, throughput, and volume size. This flexibility – the ability to configure each piece independently – is where the savings come in.

  • On the opposite end of the spectrum, gp2 is quite inflexible. Sizing a gp2 volume involves considering both the storage and throughput requirements simultaneously, as volume performance has a baseline of 3 IOPS / GB, at a minimum of 100 IOPS. In other words, gp2 volume performance scales in proportion to volume size, until the 16,000 limit. As a result, gp2 volumes greater than 1TB are often oversized relative to the amount of data to be stored in order to increase the throughput.

  • That’s why you’re probably paying too much for gp2. The extra TBs of storage capacity – and the money spent to enable it – are essentially wasted, as they were only necessary to increase the IOPS limit. Fortunately, there’s a better way: paying for only what you need with gp3.
