QNAP's already stuffed an Atom processor into a few of its NAS devices, but it looks like the company is still only just getting started, and it's now rolled out yet another model in the form of the SS-439 Pro Turbo NAS. Like the similarly designated TS-439, this one will accommodate four SATA drives of your choice, although the SS-439 opts for 2.5-inch drives to keep the NAS even more compact. Otherwise, you can expect to get 1GB of DDRII memory in addition to that Atom N270 processor, along with support for RAID 0/1/5/6/5+hot spare configurations, three USB ports, two eSATA ports, and all the usual security measures you'd expect from a small business / SOHO-minded NAS. No word on pricing just yet, but it looks like this one should be rolling out to retailers right away.
