Asus­tor AS4002T



NAS is com­ing on strong in leaps and bounds. They’ve be­come fully fea­tured servers ca­pable of all man­ner of func­tions. The porta­bil­ity of data be­tween de­vices is be­com­ing a pretty big deal even for the reg­u­lar con­sumer. De­spite all of the ca­pa­bil­i­ties a NAS of­fers, one area the con­sumer NAS has con­sis­tently been bot­tle­necked by is 1GbE net­work­ing. While 10GbE is noth­ing new, its pro­hib­i­tive cost has pri­mar­ily rel­e­gated it to the pro­fes­sional and en­ter­prise realms. Slowly we are see­ing 10GbE

lter down into the con­sumer space, and Asus­tor is at the head of this trend with the brand new AS4002T.

The AS4002T is de­signed to be a low cost de­vice that aims to ful l a sim­ple and ob­vi­ous role – net­work at­tached stor­age. The in­cluded ARM Marvell Ar­mada CPU is not suited for transcod­ing on the y or han­dling in­ten­sive tasks, but it’s more than suf cient for le shar­ing pur­poses and stream­ing to other de­vices. Its low power con­sump­tion means noise lev­els are low too, with the sound of the hard drives eas­ily drown­ing out any op­er­at­ing noise. 2GB of DDR4-2400Mhz RAM is nice to see mean­ing there’s enough ca­pac­ity to run a rea­son­able work­load with­out slow­downs or buffer­ing is­sues.

We have to em­pha­sise how much of a big deal 10Gbase-t net­work­ing is, es­pe­cially con­sid­er­ing this is a rel­a­tively low spec and af­ford­able ARM unit. If you’re us­ing a wired net­work, the painful time it takes to trans­fer gi­ga­bytes and ter­abytes of data over 1GbE is sim­ply un­ac­cept­able in 2018. We’re see­ing the winds of change though. 10GbE de­vices are slowly com­ing down in price and we hope that it will be only a cou­ple of years be­fore it be­comes ubiq­ui­tous. That will make the AS4002T a very wor­thy pur­chase with a long life. Asus­tor gives the AS4002T a three year war­ranty, a wel­come de­vel­op­ment.

The AS4002T looks like a very classy de­vice with its mag­net­i­cally at­tached front panel and sub­tle LEDs. HDD in­stal­la­tion is tool free and soft­ware in­stal­la­tion is as sim­ple as it gets which is key for the con­sumer mar­ket. It comes with a pair of USB 3.0 ports, the afore­men­tioned 10GbE port and a pair of 1GbE ports which sup­port link ag­gre­ga­tion.

A ma­jor part of the NAS user ex­pe­ri­ence is its soft­ware in­ter­face and the AS4002T, with the lat­est Asus­tor Data Master is one of the best in the busi­ness, with a host of apps and fea­tures. Back­ing up, se­cu­rity, sur­veil­lance, col­lab­o­ra­tion, cloud stor­age, VPN and more is all there.

So how does it per­form? As you’d ex­pect, reads and writes over a sin­gle 1GbE con­nec­tion are bot­tle­necked around the 110115MB/s mark with any modern hard drive. The dual 1GbE ports, when ag­gre­gated go a long way to al­le­vi­at­ing bot­tle­necks on the NAS side at least.

An SSD pro­vides the truest test though. We trans­ferred a 25GB le from a Sam­sung NVMe drive via an Asus 10GbE NIC di­rectly to a SSD in the NAS. We were able to reach a peak write speed of just over 480MB/s which is not that far from the limit of SATA when the over­heads are taken into ac­count. When you’re trans­fer­ring ter­abytes of data, these kinds of speeds are sim­ply a god­send and per­fectly il­lus­trate the ad­van­tages of 10GB net­work­ing. Now where are those switches and routers? It’s about time 1GbE went the way of the dodo.

The Asus­tor AS4002T ex­cels as a no frills stor­age so­lu­tion. If you’re look­ing for fast af­ford­able net­worked stor­age, this is as good as it gets. It doesn’t have the bells and whis­tles of some units, but if you’re look­ing for a unit that ful ls its role as net­work at­tached stor­age then the AS400T will serve you well for years to come, es­pe­cially as 10GbE in­fra­struc­ture be­comes in­creas­ingly af­ford­able. Let’s not for­get that class lead­ing three year war­ranty as well, mak­ing the AS4002T a very wor­thy fu­ture proofed pur­chase.
