sorry no experience using unraid

RAID migration will take very long on consumer type hardware. That is why it is advisable to fill up the bays with the largest drive capacity that you are comfortable with on the get go and be done with upgrading. It'll be too messy and time consuming if you upgrade later on.

A good Gigabit goes up to 120MB/s thereabouts. Well, the lousy type NAS boxes does not give you a lot of benefit in RAID 0. As you said, not enough processing power. You need a NAS with REAL CPU and memory.

Actually there are benefits of RAID 0 even though the combined throughput will exceed Gigabit speeds. Internal transfers are super fast. Transfers from internal array to external RAID box via eSATA is super fast.

No need to put everything in your desktop. I'm sure you know that you can use USB 3 or eSATA external box to store the hardisk externally. Can keep everything small and neat. Fast too.

If data is something that you can download again from the internet, then no point in getting RAID 5. It'll be faster to just download again than rebuilding the RAID array.

If data is really important, I would just put them on different hardisk and store them away.

dunno if you should consider RAID 5 as with data redundancy. for me a RAID 1 at least can consider, but definitely not RAID 5

different people have different requirement...

raid 5 more space with protection against 1 disk failure

most important is to hook up the NAS to a UPS

I m using raid 5. And experience before where 1 hdd in bad shape. Shut off, take it out and replace a new 1. ON it back and it took fews hour to generate back the data. Run smooth till now.

The nas and raid 5 work as what I want. 1 of my risk free backup plan.

what NAS u using ?

Using synology ds409+.

hai all,

I was thinking of getting a NAS for my home usage. my primary usage as follow :

1. BT download
2. Time Machine Backup of my Mac with redundancy
3. Media Stream of movie to my PS3

looking at my target usage, at minimum I need 2 bay NAS. the cheap enclosure I found so far is DNS-320 & buffalo linkstation duo (non-pro version). I bundle in 2 x 1TB he'd cost me less than 1k.

apart from those 2, any reliable similar product on the market?

thanks

as usual, the next one the sifus here will recommend u will be synology or qnap.. happy hunting.

Actually one will need to pay for quality and reliability...

thanks guys.

anybody use NAS to stream to ps3? how the performance?

I was searching online on HDD lifespan today and found this white paper from Fujitsu about using 2.5" HDD for server applications.

http://www.fujitsu.com/downloads/COMP/fcpa...ext-duty_wp.pdf


some of the points made seems relevant to me so I thought I did share. However read it with a pinch of salt... Fujitsu is a major 2.5" HDD manufacturer. Not the first time i read about using 2.5" HDD in server applications and it does seem like a very good solution (lower heat, noise, power consumption, vibration)

I guess price and size factors alone will prohibit us from using 2.5" into our valuable HDD server slots. But there is such a idea being implemented, see this

yeah seen it before. many post back i think i asked were to buy such a bay converter but nobody answer me.
but there are pretty expensive... about USD60+ before shipping. they also have the 4 drive versions.

how's this going CocoMongo?! has it arrived yet..?

That article was written way back in 2006. 2.5" in server environment is not new. My company's 1U and 2U server racks use 2.5" 10k Seagate Cheetah SAS drives. I think the main driving point behind the 2.5" form factor is the smaller size and lower power consumption. The downside of 2.5" drives is capacity but in a server environment and with RAID arrays, that is not a problem.

no info yet. I know he said the server reach him already, but i think he is just too busy to send it out. anyway knowing that prices of HDD is actually this high now there is no reason to rush him also. now torn between being eager and "meh"

that 6-slot 2.5" for 3.5" slot is awesome!! Can I know where I can buy that thing?

if u have already fully utilized the 4bays, do you need to change the power supply to power up these additional 2'5"s?

Hi, I did that before. I am using Synology ds110j.
The limitation is actually on the ps3 side due to limited file format ps3 can read.
PS3 not capable to read .avi, .mkv, etc...
