5 out of 5 eggsGreat Drive for NAS

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive - Bulk

Pros: - Ordered 5 of these 2 months ago with 0 DOAs so far for RAID6. Works flawlessly.
- I can transfer to my NAS at up to >100MB/s. Compared to the 10MB/s I got with my old NAS, I'm in love.
- I was considering going with the newer 6TB drives, but I've always preferred base-2 drives, 1TB, 2TB, 4TB etc. Idk why, just a preference. Not only that but since I got these on sale, they were quite a bit cheaper per TB than the 6TB drives.

Cons: The only con I can think of I would never take an egg off for because its the problem that all drive manufactures do. In computers, the prefixes are on a 1024 scale, not 1000. 5 x 4TB HDDs in RAID6 would give 12TB of usable space. But do the math and I end up only getting 10.9TB.... Robbed of an entire terabyte of usable space. Not only that but I left it open to another RAID6 5-drive array to double my space eventually, which would mean another terabyte gone.

Other Thoughts: NewEgg... What has happened to the delivery service? I ordered all my parts at once, paid all at once. After watching my packages sit in a warehouse on the tracking website all weekend, I received 4 different packages on Monday, 2 from UPS and 2 from FedEx. The worst part of all was that the DIMMs I absolutely NEEDED to run my build were still in a transit in a seperate 5th package that I needed to wait for. So I had my NAS all built and ready, and got to sit there and stare at it till the DIMMs arrived. That was great, thx.

5 out of 5 eggsUpdate on Drives

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive - Bulk

Pros: Great NAS Drive
Quiet
Low Power
Got it on sale for $170 when I bought it
Still alive (Purchased 11/13/13)

Cons: None

Other Thoughts: I have four of these in a three 5.25" bay to four 3.5" bay converter by Silverstone (CFP51-B). They are attached to an LSI 9260CV-8i controller on one breakout cable. When I originally got the drives, I ran all four through WD's extended burn test on their diagnostics tool. All four survived. I then make a RAID 10 array with them. It took about seven and a half days to build the array. Being RAID 10, I get only 8 TB to use as storage. I don't mind though.

These are in my personal computer, so they get turned off when my PC does. I have also moved my PC around quite a few times (On work travels) and these drives have not gone bad in any way.

I plan to build a separate NAS system that will stay at home for 24/7 use. That will probably use ten 6 TB Red Drives (8 in array and 2 for hot spares). I just have to save up for it, but these drives have proven their worth to me.

Also, I would have to note that on this LSI controller, please note that you cannot expand RAID 10 arrays. You can expand RAID 5, 6, 50, or 60 though. So I would buy all of the drives up front to make the array (From different time periods though to make sure they don't all die at the same time).

5 out of 5 eggsGreat Drive for External Enclosures

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive - Bulk

Pros: This is a great drive for use in external enclosures. It runs very cool.

Cons: None when used for the intended purposes. Don't make this your main hard drive inside a computer. For that, use the Western Digital RE series.

Other Thoughts: I usually pair this drive with a Icy Dock MB559U3S-1SB and connect it to the computer using eSATA.

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive - Bulk

Pros: Size and price combo.
Part of 3 drive NAS in QNAP.
Been running since Christmas day.
Installed with no issues.

Cons: none

Other Thoughts: Did not have problems noted in reviews. I did not do any special formatting. I simply put each drive in a tray and inserting them into the QNAP 451. Ran QNAP utilities and all good. Running RAID5 with three drives. Will add forth with price hits $140.

Other Thoughts: Newegg delivery is going downhill

I remember Newegg as having great delivery service but it has gone downhill. They now use a company called Ontrac that does not deliver on weekends. This is also a Newegg policy according to a rep I was talking with on Saturday.
The product ships from City of Industry to San Diego. A few hour drive. Ordered Friday and called ontrac Saturday to go pick up my product. Oh wait… Newegg doesn’t allow this. I now have to wait until Monday to get my product that is sitting in a warehouse 20 minutes away. A newegg rep tells me they can change the delivery address back to my workplace because that is what I do on Mondays… I find out today that they can’t actually change the delivery address and the rep just lied about it. So I have $300 worth of product sitting on my doorstep.

Poor delivery service. Another major site had my drives to me the next day.

5 out of 5 eggsBest 4TB HDD for NAS or Desktop

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive - Bulk

Pros: - Extremely low vibration
- Almost completely inaudible
- Runs very cool
- At 5900 RPM, its as fast, if not faster than most 7200 RPM drives
- Excellent option for simple dekstop storage even though its a NAS rated drive
- No excessive headparking issues with NASWare 3.0 firmware; some 2.0 eqipped drives might need to use WDIDLE to adjust delay (Google will walk anyone through this easily, tech knowledge level is irrelevant to perform this), though not all have.

Cons: None observed
