HGST Ultrastar He10 | HUH721010ALE600 (0F27452) | Power Disable | 10TB SATA 6.0Gb/s 7200 RPM 256MB Cache 3.5in HDD | 512e | Enterprise Hard Drive (Renewed)

I will not purchase from MD Tech again, and I would advise everyone to stay clear. The review is still 5-star because the original drives from a different seller are great. I've had mixed experiences with these drives. The first two that I ordered were great, worked with no issues whatsoever and have been running basically non-stop for years now. The second pair I ordered from MD Tech (to switch from RAID 0 to R10) were not recognized by my UEFI. Thought it might be a cable issue, so I pulled one of the originals that was working perfectly, and plugged in the new drive to the same cables, still not recognized. Tried the old drive with the new cables just to be sure it wasn't a bad connection that fried the drive or something, old drive worked fine. This happened with both of the newer drives.

I've been using the HGST WD Ultrastar DC HC530 14TB Data Center HDD (Renewed) for a few months now, and here's my honest take on it. Pros: Massive Storage: With 14TB of space, this drive can handle an impressive amount of data. Whether you're running a data center or just need a ton of personal storage, this HDD has got you covered. Performance: The 6Gb/s SATA interface provides solid data transfer speeds. I've noticed that large file transfers and backups are relatively quick, which is crucial for my needs. Reliability: Despite being a renewed product, it has been running smoothly without any hiccups. The HGST brand has a good reputation for durability and reliability, and this drive lives up to that standard. Cons: Noise Level: This HDD is a bit noisier than I'd like. During heavy read/write operations, there's a noticeable hum. It's not a deal-breaker, but if you're sensitive to noise, it might be something to consider. Heat Generation: It does run a bit warm. I've had to ensure proper ventilation in my setup to avoid overheating issues. Investing in a good cooling system might be a good idea if you plan to use this drive extensively. Renewed Product: While mine has been working fine, there's always a bit of a gamble with renewed products. Make sure to check the seller's return policy just in case. Overall, the HGST WD Ultrastar DC HC530 14TB HDD offers excellent value for its storage capacity and performance. It's especially great if you're on a budget and need a high-capacity solution. Just keep in mind the potential for noise and heat, and you should be good to go!

Nearly burned my house down! These drives don’t power on from a standard sata power connector and require a special molex to sata connector. No big deal I thought, plug it in and what happens? The computer chassis immediately turns glowing red and smoke is pouring out of every fan. I moved as quickly as I could to pull the power cord out of the back but before I could it has fried my motherboard (maybe the cpu and memory too, not sure yet) and the power supply. Not to mention my whole house smells like a electrical fire. I’m sure I’ll get a refund on the drives but what about the computer you just torched? Update: 8/17 - Company has promptly contacted me, issued refund, and is investigating the photos and damage before calling back to update me on any other information. Out of fairness to them for so quickly promptly contacting me directly I'll continue updating this review with progress from the company 8/19: They’ve issued a refund but have been entirely radio silent about covering the cost of the new computer I have to build since their fault part torched mine. Update 8/28: shipped those clunkers back, but just to update the company will issue a maximum damage benefit of $250. So if risking your computer, office, home or other property potentially burning down is worth $250 in amazon credit then by all means go ahead and get these. For the record I purchased both, and BOTH were defective, the support rep said in thousands of drives this had never happened but I had two drive failures in one box. I tested the second one in a different environment with a different power supply and it also instantly shorted out and started smoking. The support rep was very pleasant but ultimately couldn’t help replace everything and who has the time to for that hassle

Bought 2. The drives were individually packed and sealed in electrostatic bag. No signs of use, so externally like new. They were used for 6.5 years based on S.M.A.R.T log, no errors in the log (i don't know if those can be cleared) max temp on one was 61'C and 48'C on the other. Did read only scan using badblacks software and no errors reported. I think it's a good deal, they are silent, you can hear the head moves but the spin is silent. I think (personal philosophy) that is better to buy used high quality enterprise grade drive than cheap brand new of general user one from last say Seagate. Those are Japanese designed, made in Thailand. The SMART also reported 100% helium.

Working great one month in. I would recommend them for the price as backups. I bought 5 of these drives. 4 are in use in a Qnap Tr-004 working hard in a RAID 5 hardware setup. The 5th drive is a backup to the Qnap. They are working great. These disks are a great deal for the money and I would buy them again, and have.... (with a couple of caveats, see below) I give this a 'solid 4+ star' because of two issues: First, the drive model numbers advertised here are NOT the same as what I got. The advertised product is a _____ALE600 model number... what I received was a _____ ALE604 model number. The ALE604 model has a slightly higher failure rate long term.... The rating gets a tiny 'ding' for not being the exact same model number. Second, the first 4 drives I received had between 53,500 and 54,500 hours on them (I didn't bother to check the 5th). That's 6.2 years of use. So, they get another tiny 'ding' in the rating for being a bit old.... even a 'refurbished' hard drive. If these are being used for a critical backup, that's a lot of time on a hard drive to count on them in a crisis. I do not think these are a good idea as a primary drive as they are very used with a lot of 'mileage' on them already (unless you get lucky and get one that was stored as a 'cold' spare). If they had a couple less years of use, and were the exact model number advertised, these would get 5 stars. But if you know what you are doing with hard drives (and that these might have a lot (extreme amount) of mileage (hours) when you get them), these are great for the price. I would recommend them. I would buy again, but with 5 of these 10TB models, and 4 in a Raid 5 array, I'm set for half a decade at least (I hope). Update January 24th: All 5 drives performing well after 6 hard weeks of use.

I checked these after reciept and found no errors on the drives. Having 14TB added to my home server has been great. Now I can run my PC backups to the server and not worry about space issues. Performance is great through SATA. Installation was the norm for a Hard Drive, just a few screws and two plugs.

I've been buying 8GB USB backup drives for seemingly forever. We go through about 6 a year. I was buying them when they were on sale at the local Costco, but they've stopped carrying them. There are other suppliers of course, but it seems the costs of those drives has gone up a lot since the last batch I bought. So the search started for alternatives. For the most part, the duty is a year of light backup use, then they get moved to offline archive (read: stored in a fireproof cabinet) until/unless some of the archived data is needed. Seems like the perfect job for this recycled drive. So I bought one to try in parallel service before changing all of them. First, the drive arrived packaged well, and is cosmetically perfect. Other reviewers have reported some minor scratching or tool marks from prior service. This example has none. Not even a fingerprint. It's in a sealed antistatic bag. Had I not known that it's a recycled/refurbished drive, it could easily pass as brand new based on first impression. Powering it on was painless, with no need to play with power supply pins to avoid any inhibits that some others have mentioned. I suspect that's a 'feature' totally dependent on the particular power supply you have. Reading the stored stats from the drive reveal that it's been power cycled less than 20 times, and the service hours are well short of 50% MTBF, both indicators that this will be good in our service. Limited by the USB interface to the workstations, the read and write speeds aren't stellar. No fault of the drives of course, and based on the duty here (overnight incremental backups) those aren't really important to us. The drive was quickly identified when connected, and was scrubbed again before formatting. The drive itself is very quiet even just sitting exposed on a desktop mat during those operations. I anticipate rotating this drive into service in about a month. Based on our current arching rate, this 12TB drive should last a full year in service before it goes to storage. I'll call this demo a success for us if there are no issues during that time. Again, this is hardly a tough duty especially for an enterprise-class drive. The review will be updated if problems are discovered during the demo period. ----- Yes, I am aware that the local workstation archive method is not what others might recommend. Things would be faster and certainly more physically secure using a NAS array with ethernet. The actual service requirements make that tough. So each workstation has its own archive. I'm winding the business down and firing clients as fast as we can. Less than two active years to go, plus seven years records retention after the lights go off.

Been using it for like a year and a half now and haven’t had any issues with it at all. Currently moving it to a new system for a home NAS and expect many more years of amazing performance from it.
