HGST Ultrastar He10 10TB SATA 6Gb/s 7200 RPM 256MB Cache 3.5-Inch Enterprise Hard Drive (HUH721010ALE604) (Renewed)

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!

I had my doubts with some few negative feedback on the item, but I had faith in knowing decades of previous machines I had built on Hitachi drives. Upon arrival and installation, i was pleasantly relieved that it worked great right out of the box. Unlike previous drives, I did have to use the dongle adapter to bypass the new remote power down system standards, but once I did, it registered immediately and formatted fine. Tested rigorously three times using surface tests overnight. 100% functional no bad sectors nor a single error warnings. Proceeded to copy my old drive and it was going at 180mb/s during that write process. Overall a great unit. Read head clicking is somewhat more noticeable in random read operation but that’s been normal for most modern Hitachi HGST drives. Heat properties are fine too. File copying took 3 hours, for 3.5GB of information. No warnings for heat related issues and PC fans stayed nice and stable. 10Gb is a lot of storage! $78, Hitachi drive quality, I will take it!!

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

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.

Got one of these refurbished and it's been running without any issues for months now. The 10TB capacity is kind of insane for what you pay and it formatted and set up without any drama at all. Just a heads up that some sellers apparently ship drives with connection quirks so definitely check reviews on the specific seller before you buy. Mine came through fine and copies files at a solid speed for storage and backups. Pretty good deal overall if you do your homework.

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.

PROs Purchased 6 drives all were 10TB HUH721010ALE600, have firmware LHACT38Q. Average of power on 8067 hours or 336 days and 3 hours. Lowest received was 501 hours (20 .875 days) most were in the range of 9500 hours. Power cycle count was between 16-17 when I received drives. All passed extended 18-hour SMART battery of tests. ☼ Quiet ☼ Looks to be and feels to be in good shape, clean. ☼ Synology RS1221+ recognizes and works with them, it doesn't complain about these drives as many RS and XS series can and do, I've been very fortunate in my cautious selections to use. I've included this to assist other Synology owners with this specific model in locating working drives - ( as of 10-27-2023. /w DSM 7.2-64570 x. ) If all turns out well, I'll be bookmarking this seller and watching offerings. Caution to NAS owners. I don't care what drive source you use, make sure if it's worth keeping have several tried and tested backup plans to fall back on, anything can die for any reason. CON: ►►I don't recall seeing any power cables in my 6 boxes but as advertised, however, might be nice to have for a future use when a system won't handle these drives natively. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Initially, I started out using: WD Red Pros, after 5 years of running they still have no issues and are still in service. I added Seagate Iron Wolf Pros, after 2 years of running no issues, still in service. Now adding WD/HGSTs. - they're looking promising. (Have tried WD Gold Enterprise, those things are tanks but expensive.) I'm keeping the Red Pros and Iron Wolf Pros engaged as I integrate these HGSTs and start stressing them just in case, though I'm bit more that optimistic now than before and hope I've found a reputable source that doesn't deal in garbage. 03-14-2024 Update - Still going strong on all 6 drives with 24/7 operation in NAS, no errors on RAID5 patrols and things seem to be quite happy. Going strong for the rest the of the mentioned WDs and SGs too.

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.
