Unbelievably inexpensive networked storage options have emerged, but it’s a case of ‘False Economics 101.’
PCMag has a post advising how to avoid the pitfalls of cheap storage:
The proliferation of huge, cache-laden SATA disks in the consumer market has led to an ever-expanding array of very inexpensive networked storage products for business. More often than not, these devices offer both NAS and iSCSI SAN functions that, until recently, were found only in enterprise-class storage products — at a fraction of the cost. Are these ultracheap alternatives right for you? That depends on who you are and what you do.
A huge range of performance variables separate true enterprise-class storage products from their inexpensive pretenders. The most glaring is transactional performance. Most low-cost storage devices are based on a small number of very large SATA disks rather than larger numbers of SATA or higher-speed SAS/FC disks. These types of configurations will yield extremely anemic transactional performance, which would generally make them poor choices for hosting a busy database or mail server.
What if that’s not what you want, though? If you’re a small business without a whole lot of transactional disk performance needs or a big business that just needs a very large, low-cost parking lot for some big data, are these low-end storage devices a good option?

So be careful when you venture into the land of low-cost storage. Take a hard look at what your storage will be used for — and how it’s going to get fixed when it breaks — before you congratulate yourself for saving a dump truck full of money. Sometimes, the dump truck you know is better than the one you never saw coming until it ran you over.
