Title: What 1TB - 2TB HDD do you recommend?
Post by: hartlenb on December 27, 2010, 08:51:15 AM

I'm looking to replace the unsupported WD Green drives (WD10EARS) that I bought before reading this forum.  They work:  I can read / write data but they're pretty slow (~ 6MB/s write).  From what I've found in this forum and on the web the DNS-321 is capable of ~ 14MB/s.

So, I'm looking for recommendations on drives that you've found to work well with the DNS-321.

Thanks for your opinions.

Any 512 Byte sector SATA drive, it really doesn't matter. Seagate, Samsung, Hitachi, WD...

I'm using two WD green drives but they are the WD20EADS.  The WD-EARS drives are not supported.
The reason you are seeing the slower data speeds is not the drives fault, they are rated for 3000Mb/sec though a SATA II connection.   Your 100 base T network connection is the bottleneck.  During large transfers to the nas I'm getting between 9 and 11 Mb/sec.  Try shortening up your cable runs and remove any coiled up lengths and keep your network cables away from AC power.  You can get your 14 if you replace your nic and routers to ones that run gigabit ethernet or 1000baseT.

Hope this helps.

Thanks for the answers. My network gear (routers, switches) and NICs are all gigabit capable and are all configured to allow gigabit traffic.   

I downloaded a NAS benchmark tool from Intel.  It's supposed to simulate various traffic patterns and measure the NAS' effectiveness.  One test it simulates is concurrently streaming 4 720p video streams.  Another is straight forward file copies.  Avg throughput for the streaming was 8.8MB/s.  File copy to NAS was 11.9MB/s (writes) and filecopy from NAS was 10.0MB/s.  So my performance may not always be as bad as Windows was showing when I first posted.

I've also just ordered two Seagate 2TB drives to compare performance.

i am using 2 samsung 2tb spinpoint drives (fry's oem specials) they appear to be working fine so far - the unit is freezing but that appears to be the embedded "servers (upnp av and itunes)" issue
