# VMware vSAN vs Nasuni vs AWS Storage Gateway for an enterprise IT team replacing aging on-prem NAS: which is worth the migration?

<a class="a a--md" elv="true" href="https://www.g2.com/products/nasuni/reviews"><strong>Nasuni</strong></a><strong>:</strong> built for this job. The master copy of your files lives in cloud storage (like Amazon S3 or Azure), and a small box in each office keeps a local copy of the files people use most so they open fast. Every site sees the same set of folders, and continuous saved versions in the cloud can replace a separate backup. Trade-off: pricing is complex and pricey.</li>

<a class="a a--md" elv="true" href="https://www.g2.com/products/aws-storage-gateway/reviews"><strong>AWS Storage Gateway</strong></a><strong>:</strong> the lightweight bridge. Staff get the usual mapped network drives, but the files behind them live in Amazon's cloud, with recent ones cached locally for speed. Quick to set up, strong for backup and a gradual cloud move. Trade-off: it is a connector to AWS, not a full multi-site file system.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/vmware-vsan/reviews"><strong>VMware vSAN</strong></a><strong>:</strong> the outlier. It builds storage from the disks inside your VMware servers and is meant mainly for running virtual machines. It can serve shared folders, but that is a side feature, and everything stays in your data center, not the cloud. </li>

&lt;p&gt;From G2 reviews, Nasuni holds up best for a true multi-site NAS replacement where cloud becomes the source of truth. G2 reviewers who&#39;ve run the migration describe the single namespace across sites as the feature that justifies the price, with continuous versioning replacing backup infrastructure they were paying for separately. NetApp ONTAP deserves to be ahead of vSAN on this list for NAS replacement specifically, with reviewers citing it as the closest to a like-for-like NAS swap that also opens a cloud path, while CTERA comes up as the direct Nasuni alternative worth pricing when the Nasuni cost conversation stalls.&lt;/p&gt;
