In follow-up to my previous article about bind mounts<\/a>, here is the first in a series on storage strategies (while everything contained in this series is applicable to desktops and laptops, the main thrust will be towards servers). Today we’ll look at local\/simple storage options (DAS<\/a> – both the spinning and solid-state varieties).<\/p>\n

The most basic form of utilizable storage is the direct-attached (or DAS) variety. In short, DAS covers any drives that are physically connected to a computer – hard drives, SSDs, etc.<\/p>\n

Spinning disks, aka hard drives, are the most common form of DAS – and are extremely similar between consumer and professional levels (the only main differences are price*<\/sup> and guaranteed reliability): they’re a very mature, stable technology, and, excepting recent problems in Thailand<\/a>, have been pretty cheap for a long time.<\/p>\n

Depending on the server, there will be anywhere from 2-12 (or more) disk slots. If the disks are sized equally, they can be either added to a RAID (a topic for a future post on fault-tolerance), or used individually.<\/p>\n

A more recent alternative to hard drives have been solid-state storage<\/a>. SSDs use flash memory – which can be more fault-tolerant than disk drives because there are no moving parts. While, as with all devices, there is a failure rate with flash storage, it [generally] fails more gracefully than a spinning disk, as individual cells of the flash will wear-out\/become inaccessible, rather than a platter \u00a0physically crashing.<\/p>\n
