I have a 5200 (non-pro) and want to upgrade all my 5x 500gb drive with WD WD10EADS 1.0TB or Samsung HD154UI 1.5TB. WD WD10EADS has a very good reputation but it is more expensive than Samsung in terms of $/GB. However, as per thecus official compatible list, 1.5TB drive is not recommended for non-pro 5200.
I can get the price of Samsung HD154UI 1.5TB just 25% more than WD WD10EADS but I got 50% more capacity. Would anyone has experience on this two drive and have any comment?
Also anyone upgrade to WD Caviar Green WD15EADS 1.5TB. It is more expensive than Samsung but in terms of stability and reliability, is WD harddish better than Samsung. Pls advise

Hey mate.
I have 4 WD EcoDrive 1TB's in my original N5200BR NAS and they have been up and running constantly for nearly a year now. The 5th one failed a couple of months ago (reallocated sector then died) and I replaced it with a HD154UI. Works perfectly. In fact, what's crazy is that the Samsung actually runs a few degrees cooler than the WD's, so don't be fooled by the whole "WD EcoGreens are more energy efficient so should not generate as much heat" argument.
Before the WD's I had 5 Samsung 500GB drives in the box and they also worked perfectly. The only reason I replaced them was for extra storage. I now have those drives running in a RAID on my PC and they are still running perfectly after about 3 years now. 2 have failed but were replaced under warranty within a week.
Hope that helps you. If I were you I would got for the Samsung 1.5TB drives.

TLER can no longer be enabled on the new versions of WDxxEADS drives whereas CCTL can be enabled on the Samsung drive you mentionned so go with the Samsung.

Were you unable to enable TLER on these? I've just bought 5 myself. 2 were manufactured on 1st Oct 09 & 3 on 5th Oct 09. I've managed to enable TLER on all of these. What are your transfer rates like? I was running the latest "stable" firmware and my write speeds were all over the place, the drives seem to be pausing every couple of seconds. Anyway I felt brave and flashed the V2.01.10.17 beta firmware and this has helped the write speeds a great deal. The read was ok with both firmwares. |

Drewy,
I was getting 40-45 MBps write speeds (30-35 MBps before cpu upgrade) until one of the 5 WD15EADS-00P8B0 started having the stalling issue under heavy load reported by QNAP and Synology users and I think also by someone with a n3200 pro. In my case the busy light on tray 3 stays on during a minute or two freezing the array, then everything continues to work normal for a minute or so, stalls again etc.
Now I'm running the raid in degraded mode until I hopefully have the faulty drive replaced. The trouble is getting WD to accept RMA because their diag tool shows no error on the drive.
If they end up not accepting it I guess I'll try out 4xraid5 and the stalling drive as JBOD jumpered in sata1 (1.5Gbps) compatibility mode.
I also have 2 WD15EADS-00P8B0 manufactured 1 Nov. 2009 on which WDTLER.exe no longer works.

polywave: did you end up getting the Samsung hd154ui (1.5tb) drives? If so, how is it working and what version of the N5200 firmware are you running? Someone claims on this thread www.thecusforum.eu/showthread.php?t=1637to have gotten 5 of them working in a RAID5 array on an N5200 running 2.00.16 I have an N5200 (non-pro) running 2.01.09 and am close to pulling the trigger on several of these Samsung drives. The official Thecus documentation says not to go over 1tb so I'm looking for as many success stories as possible before spending the $ (and my time) on this. Also, does anyone know if I had to move from my current 2.01.09 back to 2.00.16 how I'd do that?

Maybe these drives will have issues with the N5200 (Pro) on the latest non-beta firmware because the EARS-disks run with 4k instead of 512bytes clusters as one of the first harddisks until now.
If you want to be sure, don't take a disk model not mentioned in the comp. list or tested with other users.
/edit: sorry, thought it was about the EARS-disks instead of EADS...

dconway, maybe this reply is too late for you. My N5200 is not pro version and I bought 3 Samsung hd154ui for raid 5 running around 2000 hours now. Everything is very good. The temperature is low. I got around 35-40M/sec which I think is Ok as my gear is not that great. My firmware is 2.01.10.17. I think it just depend on what price and support do you get. I think both Samsung or Western Digital is good.

I used to swear by WD drive, then I had a some WD4000RE 400gig drives, which all died within months.
I was so amazed a this mass death of WD drives I replaced the PSU in the machine with a bigger, more expensive one, and bought a UPS/power conditioner to feed them the smoothest power I could.
I replaced them with the 500gig RE drives, and guess what, they died too.
So for me that was enough, so when I bought my 5200Pro I bought the biggest drives I could for the cheapest price, and they were the 1TB Samsung Spinpoint F1 drives, and you know what, no problems at all. I've just replaced them with the new 2TB Samsung drives, but the old 1TB drives are still working perfectly well, so I will use them to backup critical data.
