Dual core vs. Multi-core?

What ReadyNAS are you interested in?

FWIW, the ReadyNAS devices are evolutionary products that may undergo various changes/improvements over time. For example, here is an old FAQ about the NV/NV+

» What is the difference between the ReadyNAS NV and NV+? First of all, the NV+ is an evolutionary running production change over the original NV. In retrospect, the NV itself was already improving through running production changes, and a lot of features we are introducing formally in the NV+ hardware had already started appearing in the latest batches of the NV, starting in August/September timeframe. So pretty much other than the LCD panel, the hardware on the NV+ is very much the same as the "rev B" NVs that we have been shipping. That said, I will post the improvement in the NV+ since the original NV which was introduced back in February this year. Keep in mind that the RAIDiator firmware runs across commonly across the ReadyNAS family, so the software features remain the same. LCD panel. Feedback on status and event information are now available immediately just by glancing at the NV+. By default, the IP address and disk usage of the NV+ is displayed, so there's no guessing what IP the ReadyNAS is set for and how much disk space is still available. Also status and events such as disk failure, disk removal and insertion events, USB device events, overtemp condition, etc are displayed as soon as it's triggered. This is in addition to the alerts and logging you've grown to be accustomed to with the ReadyNAS. In addition, boot statuses are now in readable form, so you no longer need to rely on a LED chart to see what's going on. The LCD panel will shut itself off after 5 minutes if there are no failure condition. This prolongs the life of the LCD and eliminates the unnecessary glow if the NV+ powered on at night. Also, it keeps the nice clean look you're accustomed to with the NV. Quiet power supply. The original NV had a small high-revving fan in the power supply that helped out in cooling the PSU components, but, let's just say, also caused the NV to be louder than it could be. The NV+ now uses a fanless power supply with updated components that can withstand the higher temps. This results in the NV+ being noticeably quieter than the original NV. The "rev B" NV also utilizes the same NV+ power supply. We value our original NV users, and will be providing a retrokit power supply kit that will allow for the same quiet operation. Improved fan circuitry. The mainboard now has a more robust threshold for handling the wider a ranges or fan RPM. The original NV fan safe range was ~1900-2100 RPM. The NV+ now utilizes a fan that can span speeds from 1600-3000 RPM, allowing for a slightly quieter setting at idle mode, and allowing the fan to spin up high enough for the hottest drives in warmer climates and air condition-less rooms. The "rev B" NV also utilizes the same mainboard with a different fan that ranges from 1600-2400 RPM. More robust scheduled power-on. The NV+ mainboard now handles scheduled power-on events more gracefully when there is no power to the unit. Previously with the original NV, a power-on event when no AC was applied would result in needing to release the battery before the NV would boot again. The "rev B" NV utilizes the same board so it will also handle this condition identically to the NV+. Retrospect for Windows and Macs. The NV+ comes bundled with a 5-user license for Retrospect for Windows and Mac users. We have a growing Mac user base (which we love), and partnering with EMC to bring a quality backup program for both Windows and Macs was definitely a high priority. Now more users have a choice on how to safeguard their data -- centralizing backups with our integrated FrontView Backup Manager or using Retrospect where FrontView Backup is not feasible.

Even the current generation of ReadyNAS "Business Edition" units have been updated to a 2nd Generation. They are now known as "ReadyNAS Pro" and the home user / prosumer line has been rebranded as "ReadyNAS Ultra" (formerly known as "Pioneer Edition"). During this change, the CPUs on some of the units were updated. Have a look here to see some of the CPU changes: http://home.bott.ca/webserver/?p=499

Second Generation: Pro2 – 1.8 GHz Atom D525 (dual core) Pro4 – 1.66 GHz Atom D510 (dual core) Pro6 – E5300 2.6Ghz CPU (dual core)

does the pro4 really have a slower cpu than the pro2?

Yes :-(

The 4-bay and 6-bay Ultra/Ultra Plus/Pro Series models were designed before the 2-bay models. The speed difference between the CPU in the Pro 2 and Pro 4 models isn't that much.

Well I guess the difference between 1.8 million and 1.66 million aint much either, but that 140,000 can still buy a decent house or a really sweet car or buy a lot of beer. :shock:

A dual-core processor is a multi-core processor.

Stating multi-core implies more than 2; since dual-core processors are generally marketed as such. It's like the difference between "a couple" and "a few".

I'm considering buying a Pro 6 to augment my NV+. I want to move to a 6 drive system to increase redundancy, and then do backups of the Pro 6 to the NV+ (which I will place offsite). I've seen the Pro 6 advertised as both multi-core and dual-core and I wondered if there was more than one model.

There is only one Pro 6 (RNDP6000-200). It is available including/without disks.

This is simply an example of marketing terms being used interchangablely, even if they technically may or may not be the same.

multi = more than one
dual = 2

dual = multi
multi >= dual
