## Description

HGST 0F30144 Ultrastar He12 512E ISE HUH721212ALE600 12 TB SATA 3.5" 256MB Cache 7200RPM Hard Drive

Review: Good drive - These are good drives, used for storage /backup so rarely run-up but haven’t let me down yet.
Review: Bought this based on its excellent results in the Backblaze reports. Performance is good and great value for 12TB and 7200rpm. One small annoyance: there are more mechanical noises than I expected from a modern HDD (and this drive has passed all SMART and bad sector tests). They are audible through a full tower ATX case (Fractal Design Meshify 2XL) despite being mounted using rubber grommets etc. So you certainly know when it's working, much like a 1990s HDD or 5.25"/3.5" floppy drive. Not a big deal for me but something to be aware of.

## Features

- Instant secure erase (ISE), endurance optimized with field-proven helium design
- Dual safe firmware for reliable updates, power efficient with lower idle W/TB than air-filled drives
- High capacity storage for big data storage applications, perfect for cloud and hyperscale storage that need durability and security
- Optimal for high-density data centers and centralized video surveillance for reliability, capacity density, and power efficiency
- 5 year manufacturer warranty, 2.5 million hours mean time between failures

## Questions & Answers

**Q: What is the warranty on this 12GB drive?**
A: Hi, The warranty is 5 Year Manufacture Warranty which can be claimed by going on WD.com under warranty claim. If you purchase from us Serverpartdeals and you have a failure we would be happy to assist you in getting a quick replacement. As a seller of these drives, we do not see failure rates to be alarming. More often with Enterprise Drives you have the quality to last you past 5 years of use. Shipping is also very important to make sure there is no damage to your drives, hence we use suspended HDD boxes custom made for these drives do avoid failure and intern warranty claims.

**Q: What is the date of manufacture?**
A: The drives I purchased were manufactured about a month before I received them. I believe these drives are still manufactured in the same factories which belonged to Hitachi before they were bought out by WD. But I don't know whether the particular drive you are looking at was on stock at Amazon or the supplier for longer than that. However, I would suggest you don't need to worry about the manufacturing date, as the warranty will start on purchase date. Let me tell you, these are the best and most reliable drives you can buy. I have Ultrastars running in my servers since over 10 years (yes, never replaced), none of those ever failed me.

**Q: What is the year of manufacture?**
A: I guess it depends on amazon's stock. Mine were manufactured a month before I received them. If you order now I'm confident you get 2020 drives.

**Q: s this hard drive work with desktop pc ?**
A: Yes

### ⭐⭐⭐⭐⭐ Review
*by M***R on 8 December 2020*

This is an enterprise-quality drive --- a big investment in reliability and huge capacity. This is the first drive I've purchased with more than 6-TB (my preferred drives to date have been Western Digital Black 6TB drives). I have to say, I'm largely a convert. One little gotcha -- as a newer drive, and one aimed at the enterprise market, the screw holes for mounting the drive are not the same as the standard ones used on 500-GB to 6-TB drives of years past. Two are the same, and two are different on the sides, and similarly on the back. So while it's plug compatible (as a SATA drive) some mounting brackets are not compatible with it. I have an older Mac tower with four disk slots (mounting brackets not compatible) and an external RAID array enclosure with 4 disk slots (mounting insertion completely compatible). So, buyer beware ... look at the pictures of where the mounting screw holes are, and make sure they match your setup (the change is readily visible ... not a slight misalignment, but some holes missing, some extra threaded holes).
