New 4TB 64MB Cache 7200RPM Enterprise Grade SATA 6 0Gb s 3 5" Hard Drive | eBay

---

So I've ordered at least 120 of these drives now and they are currently in various burn-in stages and should go into production next week. After a few more weeks, assuming all goes well, we'll order another round. Overall, I am liking these drives so far and would recommend.

Testing:
We shoved all the drives in 36 bay Supermicro chassis and LSI 9280 cards and built out 3x12 disk RAID-0 configurations. From there, we would monitor the LSI card for errors as well as the system logs. For testing, we ran both a patrol scan on all the disks as well as a ---- badblocks -p 100 -w -v /dev/sdb ---- just to make the system do lots of reading and writing. If you have other good testing methodologies, feel free to tell me.

This process also prompted me to start documenting the tools that I am using and building more. They are available at: chuckleb/linuxdisktools · GitHub. It's a bit barren right now but I'll be writing up some in the next few weeks.

Reliability:
Of all the drives we have had, about 2 failed (dropped out of a RAID array) and 2 have media errors after about 4 days of testing. About 4 have shown signs of bus resets or unexpected sense errors, though I cannot attribute them directly to the drives. We've had a couple of slots on our test system that need to be re-validated. I would say about an overall ~4% failure rate out of the box, probably similar to any other vendor.

These drives are pairing up at 6Gb/s to the slots, have all the features of the RE drives, and the LSI cards like them. I've had dropouts using desktop drives and green drives on the LSI cards, this doesn't seem to happen.

The drives have a one-year warranty and the vendor is very willing to exchange, prepaid return label as well.

Pricing:
The prices have swung around in the past 2 months from a low of $135 to a current $145. This could be due to supply or they are just testing the market, but they have a large stock of them as far as I can tell. I suggest asking for a bulk discount. Credit card or Paypal only, they won't do a purchase order :(

Shipping:
They arrived well packaged, for small orders (<5 drives), they were in anti-static bags and wrapped in multiple layers of pink bubble-wrap. In the large orders, they were in the 20-pack drive boxes and also an interesting 32-drive box , all sealed nicely. The boxes all had adequate protection and nothing moved when we shook the boxes.

Seller communications:
Wonderful. Jackie is the rep that I have been working with and she's helped me bulk order as well as arrange for returns. Absolutely flawless support, answers questions clearly and prompt response.

Edit: 3 dead drives out of 125 so about 2.5% fail rate. All failed during initial tests.

Great write up, and very useful to find how enterprise guys are breaking in the drives. I have been looking for this type of info for a long time. Thank you. Time to breaking 24 nl-sas drives and 48 old 400gb data drives and see which ones are still working.

Can't say that this is the method others are using but it seems to kick the drives out pretty quickly. I have a whole stack that I need to run through this as well. Also trying to see if I can parse SMART for cases where I don't have an LSI card to get errors from.

You make me think about buying some of these. What do the SMART values like power on hours look like when you get them? I'm interested to see if these are "new" drives or drives where WD took an RMA, decided drive was good then resold as white label. I guess WD could reset SMART values too but meh.

I'm getting in a batch of 10 tomorrow and will pull POH before we send them to get installed. Here are the ones that I've been running on and testing. Unfortunately the LSI card gets in the way of SMART queries.

Must say that I am unimpressed by WDC's website. Provides no useful information. The drives seem to match up and the firmware seems current/correct.

Western Digital WD4000FYYZ
I'm with ya on the WDC site not being too useful. The ebay auction says 1.4lb each. The WDC link is 1.66lbs.

Are you able to spin down drives when not used? That would save much power I'd imagine.

1.658 lbs each according to my postage scale. It may weigh less when empty, the 0's are hollow in the middle like empty calories.

Yes, the drives spin down just fine through the LSI card. Assuming that I trust what the LSI card says, but mine shows my 2 GHS drives spun down right now at home.

So wish I could afford new drives right now. Although I might try to convince the wife on the 2TB Enterprise ones they have since my Greens are dying (thank god for RAID-z2)

Spiffy! You can always email and ask for discounted if buying bulk.

Wanted to mention that they are running out of then until the next batch. I had emailed to get a large order in. I am holding off for a few weeks until they restock, leaving the drives for you all to buy :). We aren't in a hurry yet...

I also have been using go hard drive for quite a while.

My latest purchase was 10 2tb drives for 57.95 a piece over 2 shipments. 3 were damaged in shipping, someone forgot to add the extra bubble wrap. This was the first time I have had any trouble. Drives were shipped back with a free shipping label, 5 business days from ship of defective drives to receipt of replacement drives.

Better return policy and service than any vendor I have ever delt with.

Back in Jakarta from Bali and about 30 more hours of flying left. I might buy a few just for NAS testing as an alternative to the lower speed NAS drives.
