3 out of 5 eggsOne works, one doesn't

This review is from: Western Digital Red NAS Hard Drive WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Pros: I ordered two of these. The drive that works does just what I want it to. Decent speed (though not the fastest) and works very well in my storage array.

Cons: One drive was DOA. I attempted to create a new RAID volume with the drive and it was immediately classified as degraded by the controller. I swapped sata ports and used a brand new cable to be safe, but problems persisted. A SMART check in HD Tune fired a warning and revealed that the drive had a high "Current Pending Sector Count" and an error test sent the pending sector count soaring. Over 2% of all sectors were found unusable by the error test.

Other Thoughts: I really dislike having to pay over $10 in shipping just to return a drive that should be working in the first place, especially with drives like this that are supposed to be reliable enough for your NAS.

1 out of 5 eggsDOA

This review is from: Western Digital Red NAS Hard Drive WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Pros: Newegg shipped fast. Packaging much better than the past, but could still be better. Shipped in cardboard box with two plastic inserts to suspend drive in air, and that was in another box with air pillows.

Cons: DOA DOA DOA. Been a long time since I got a DOA drive.

Other Thoughts: Added drive to fileserver and started array repair. It failed. I then ran a smart test & it had an LBA error.

5 out of 5 eggs

This review is from: Western Digital Red NAS Hard Drive WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Pros: Ran Bart's Stuff Test 5 ( HDD stress test) which takes 3 days to complete to see if the drive is bad or not. It passed the test and has been working great for 6 months(24/7) with out problems, No S.M.A.R.T errors at all . Not the fastest drive , but i knew that before buying it. I got it for the 3 year warranty.

Cons: Cost to much money, prices need to come down a lot!

Other Thoughts: Guys do you self a favor and run Bart's Stuff Test 5 ( HDD stress test) which takes 3 days to complete. If your hard drive is bad it will fail with in this time period. This way you don't lose you files. Also use Crystal disk info or HD tune to monitor S.M.A.R.T errors.

4 out of 5 eggs3 of 4 Totally Survived Fire

This review is from: Western Digital Red NAS Hard Drive WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Pros: I had four 2TB WD Reds in a Sans Digital external enclosure running RAID 5 that was sitting on top of a mid-tower and underneath an HP LaserJet in a house that burned for 36 hours. The heat caused the HP LaserJet above and the plastic in the USB ports of the mid-tower below to start melting. If that were not enough thermal stress, the fire department pour 250,000 gallons on the house and all this happened during a sub-zero winter. In other words, the drives got a really nice heat treatment: they were annealed an elevated temperature for an extended period of time and then rapidly quenched to below freezing.

Anyways, four 2TB WD Reds initially survived the fire. After about 6 weeks one began to fail. I have been using the other three drives for over three months now and it is clear that they have totally survived. So despite all the DOA/RMA issues with these drives, there is a level of reliability with them that is significant too.

Cons: Frankly, my beef with these drives is the performance. I replaced 640GB WD Blacks with these 2TB WD Reds. I did not expect to see much of a difference because I am only using FireWire-800 (not USB-3.0, eSATA or Thunderbolt), which I would have thought would have been the limiting factor... it wasn't. The performance took a very noticeable hit and playing HD content seems to require a couple seconds of buffering. Although I RMA'd my Red dead from the fire, I actually replaced it with a 2TB Black.

Other Thoughts: The performance of Reds is not good enough for a mildly demanding individual peripheral storage user... let alone multiple users in an NAS environment. In some situations WD should be completely ignored when they say things like you shouldn't use Blacks for RAID.

On the other hand, Sans Digital makes some beastly Mack Truck enclosures.....

5 out of 5 eggsvery pleased

This review is from: Western Digital Red NAS Hard Drive WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Pros: Got 6 of these (3 here, 3 elsewhere) and all of them have been running 24/7 for a couple months with no issues. Low power draw, quiet... perfect for a home NAS.

Cons: none really

Other Thoughts: I had heard some bad things about these WD Reds, but I got them anyway and have been happy. No issues at all.

5 out of 5 eggs2x WD 2TB Red

This review is from: Western Digital Red NAS Hard Drive WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Pros: -Plug and Play; I plugged both of my drives in via SATA3 and the motherboard BIOS instantly recognized the drives and wanted to format them.
-Fast; I have two of these set up in RAID 0 for games and they are nearly as fast as an entry level SSD. Benchmark on two fresh formatted disks was a bit shy of 250mb/second read and write.
-Reliable; I have never had a Western Digital drive fail on me and I expect these to be no different.

Cons: None as observed.

Other Thoughts: If you want a solid performing RAID or NAS solution this is the drive for you.

5 out of 5 eggsWorks well

This review is from: Western Digital Red NAS Hard Drive WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Pros: I've been using these drives a while and I have no complaints. I bought these to replace Seagate LPs that I was using that kept dying on me. No complaints.

Cons: none that I can think of

Other Thoughts: I little pricier than the Greens, which I've had trouble with in the RAID5 I am running. Black was a little more than I wanted to pay and now WD came out with Red. Definitely worth the extra money of not having to rebuild your array constantly.

5 out of 5 eggsGood speed for FreeNAS

This review is from: Western Digital Red NAS Hard Drive WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Pros: Have been running 6 of these in RaidZ2 with FreeNAS for just over a year, total actual running time around 7500 hours. Automated SMART tests and ZFS scrubs have never detected any errors.

Drives are fast enough for backups and file sharing. iSCSI across gigabit ethernet usually peaks at 500-600 Mbps.

Cons: Nothing in particular

Other Thoughts: Not the fastest drives but you don't need always need the fastest. These are fine for bulk storage.

4 out of 5 eggsIntelliPower

This review is from: Western Digital Red NAS Hard Drive WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Pros: These are not high performance drives, but I bought them for sustained performance in a RAID 5 server array. IntelliPower means they run from 5400-7200 RPM's as system needs require.

Cons: None

Other Thoughts: After talking with WD rep I am confident these work with a large number of untested RAID controllers. Don't be overly concerned about this when selecting a controller for your build.
