HGST Deskstar NAS 3.5

  • neweggOwned For: 1 month to 1 year

5 out of 5 eggs I currently have seven humming in my FreeNAS raidZ3 array. 03/24/2016

This review is from: HGST Deskstar NAS 3.5" 4TB 7200 RPM 64MB Cache SATA 6.0Gb/s High-Performance Hard Drive for Desktop NAS Systems Retail Packaging

Pros: Fast, works good and survived a four pass badblocks test.

I have not done any major file transfer testing mainly due to the fact that a gigabit network link is currently the slowest part of the whole system. However creating a dataset that has compression turned off with DD gives me the below results(note since NewEgg filters comments you will need to look up the correct command structure if you want to do this):

dd if=/dev/zero of=testfile b#s=1024000 count=50000
50000+0 records in
50000+0 records out
51200000000 bytes transferred in 95.467597 secs (536307623 bytes/sec)
dd if=testfile of=/dev/zero b#s=1024000 count=50000
50000+0 records in
50000+0 records out
51200000000 bytes transferred in 59.494667 secs (860581335 bytes/sec)

That is a 47.68GB file Written in 95.467597 seconds and read in 59.494667 seconds. In other terms write at 511.462805748MB/s and read at 820.714316368MB/s. CIFS tops out around 130MB/s on a gigabit connection. In the future I hope to upgrade to some 10GB networking cards but at the very least this should keep me going for the next few years.

Cons: No smart conveyance test. The 3TB WD green has one yet this drive does not...

It probably will not get you in with the ladies unless they are geeks too though they are likely already taken. I am sure somewhere out there someone may have proposed to marry my computer though since the drives are so crazy fast it's a lot of hardware but 14TB of USEABLE space at SSD speeds....

Other Thoughts: This is in my Dual Xeon E5640 SuperMicro X8DT6-F, 48GB ECC ram FreeNAS system.

I currently have 2.1TiB used and my latest scrub took about 1.7 hours to complete. This is a raidZ3 array with 3 drive redundancy, What that means is basically if I load ten TB of data on it and up to three drives fail EVERYTHING is still intact.

I am using the in FreeNAS a FreeBSD variant and did a short SMART test followed by a four pass marathon of BadBlocks. After a short and long SMART test the drive was performing just fine. For those unaware of what bad blocks does here is a little info:

Badblocks performs a pattern write to the complete drive followed by a complete read. The patterns are, 01010101 10101010 11111111 00000000

Badblocks and smart testing is about 560 minutes per pass. A smart long test is a single pass while a complete badblocks pass is technically two full passes, one to write to the entire drive and one to read. This puts the drive active for around 84 hours straight. If it can pass that with flying colors then I think it's safe to trust with my data.

If you are getting a drive and not checking it for problems before you put your important data on it then do not complain when there is an issue. You have to think about how complex these things really are.

In 1956 a five MegaByte hard drive was nearly as large as a two refrigerators side by side.

The heads flying over the media float on a cushion of air about 3 nanometers over the disk which in this drives case is spinning at around 5400 RPM. This is the equivalent of a 747 flying at around mach 800 less than 1 centimeter from the ground counting every blade of grass while making less than ten unrecoverable counting errors in an area the size of ireland.


4 out of 5 eggs Case works pretty well, wish there was just a bit more room behind the drives. 01/16/2016

This review is from: Rosewill RSV-L4500 - 4U Rackmount Server Case or Chassis - 15 Internal Bays, 8 Cooling Fans Included

Pros: It's large enough to easily fit my 850watt modular PSU and Supermicro X8DT6-F board. The fans move a decent amount of air though I already replaced the rear 80mm fans with PWM fans and will get three 120MM PWM fans for the middle fans. The drive bays are large enough to fit all the drives and there will be a little space for airflow once my system is complete. I will be starting off with a seven drive RaidZ3 eventually expanding to two vDev's and a total of 14 drives. I currently have the drives staggered with three in one bay and two in the others with quite a bit of airflow.

Cons: When the bays are filled the airflow will require stronger fans. While doing a drive burn in with BadBlocks the temps were getting up to 36c, the room was around 76F at the time so when I expand the vDev the fans will have to move more air.

I would have prefered to have another inch or two of space behind where the drives mount for plugging in and arranging cables as well as something below the middle fans to help control the airflow and create a better push/pull configuration. Right now I am guessing that the middle fans are not working as well as they could but some foam rubber will fix that when I get a chance.

Other Thoughts: I have a pair of hyper 212Evo's in this for cooling. Since I am not using this in a datacenter I just did a little cave man engineering and knocked a couple dents where the coolers sit to give them clearance so the top will fit on. If I had not had them already mounted to the MoBo I would have just given the copper heat pipes a trim to make them fit.

The included fans are not even Rosewill fans, they are BOK brand Model BDM12025S .10A draw and 1600RPM for the information I can find. And in the 35 to 45CFM range for the 120MM fans. The 80MM fans are BOK brand BDM8025S .10A draw and 2000 RPM, I would estimate they move around 12CFM as the fans I replaced them with move that at their lowest RPM and were fairly close to the same flow. I replaced the 80MM fans with Cooler Master Blade Master fans and will likely use the same for the middle 120MM fans and get a faster nonPWM fan for the front fans rather than to try and use PWM fans that far forward.

Overall I think the case was well worth it and at a good price point for a home user who wants a lot of space for the money.

5 out of 5 eggs Works for my router 11/19/2015

This review is from: D-Link DGE-530T Gigabit Desktop Adapter 10/100/1000Mbps PCI 1 x RJ45

Pros: Works with Linux. Dropped it into my ClearOS based router box and changed a few settings and it works.

Cons: Could have cost less, been worth more, cured cancer, cleaned the air, fixed the hole in the ozone layer, generated clean power, fed the poor among other things but it didn't.

Other Thoughts: Turned an old 2.8Ghz P4 into a router. 3GB of ram in a intel board with dual NIC's. Sadly one was gigabit while the other was only a 10/100. dropped this in and the whole thing is great. It's humming away in a closet right now.
