Rotational Vibration Safeguard (RVS)

One of the greatest hindrances to hard disk performance is vibration. Like a needle on a record, the disk drive’s head must try to follow narrow data tracks in order to read (or write) information. These problems are particularly acute in multi-drive systems, because drives tend to be installed alongside each other, in arrays. The vibration caused by the rotation and seek activities of nearby drives can affect the whole array, progressively disturbing the operation of each drive in the system. The drop in performance can be significant. That's why the Deskstar NAS hard drive has an advance Rotational Vibration Safeguard (RVS) that anticipates disturbances and counteracts them, maximizing performance in the most arduous conditions. If the RVS sensors feel a vibration rippling through the drive, they send a signal to the actuator that controls the head’s position. The actuator then compensates for the disturbance, counteracting it with an equal and opposite force. In this way, the head is able to 'ride' the vibration and stay on track, helping to prevent data loss or corruption.

All 4 drives were DOA

Pros: Seemed like a decent price at the time

Cons: All 4 drives were DOA, currently filing 4 RMAs

Other Thoughts: These were shipped as a 4-drive retail bundle - 4 retail boxes inside a HGST labeled brown box. I had previously ordered 2 single drives and both of those were detected correctly

No sold yet

Pros: I have been using these hard drives for 4 days and every time I measure the speed is less than 160 MBS (raid 1).
The first day I put them to a test but the software told me that they did not pass the test (Long generic), but I made another test with a different one but he told me that if they passed the test (I'm confused). But they are working fine but so loud.

Cons: So Loud,

Other Thoughts: I'm really not satisfied because I thought they were faster but I do not know if it's the Raid card that I have but I think I'll return them and buy the WD Red Pro, because the warranty is 5 years, these are only 3, and they are more faster like 200mbs which is not very good

excellent drives

Pros: good price:capacity ration; good performance; excellent reliability in my experience in NAS systems

Cons: not really any I've experienced

Other Thoughts: generally HGST NAS Drives like this work really well in my experience. They are my go-to part for the last few years. I've got 2Tb units still in service after 3-5+ years and they are still going strong. Certainly recommended parts.

Very Good HDD

Pros: -4TB at a pretty good price, if you can buy on sale, although during sales, the higher capcity varients are often a better value.
-7200 RPM, SATA 3.0
-Arrived in very sturdy packaging, Seagate & WD could learn from these guys! LOL!

Cons: -None really

Other Thoughts: -I honestly think the entire HDD industry needs to embrace large on-board cache as a necessity, people don't buy drives in 4TB+ Capacity to store small files under 128MB (Currently even the highest-end Enterprise HDDs from the likes of Seagate & WD max-out at 256 MB of cache), I think at a bare minimum all large capacity HDDs should have 1 GB of onboard cache, which would drastically increase transfer speed for medium-sized files and actually justify SATA 3.0 existing. Yes you could set up a caching solution with a SATA SSD in an array, however that's inconvenient, cumbersome and not worth-the-cost for my purpose for these drives.
Just leaving my thoughts, these are great drives, I own 4 now, 1 in my server, 2 in my desktop (Game Library) , 1 for back-up.

HGST hard disks have been good to me over the years.

Pros: Two of the disks formatted cleanly, and a detailed scan by ChkDsk found no bad sectors. The third disk was DOA and is being replaced by Newegg.

Cons: One of three disks was DOA. The platters rotated, but the disk was not recognized by Windows in Device Manager. I know someone energizes HGST hard disks before they are sold because the SMART data always indicates a small amount of use, but a more detailed testing regime might prevent the retailer and the user from having to contend with a DOA unit and its associated costs.

Other Thoughts: I heartedly recommend HGST hard disks; they work well for the length of the warranty, and on the rare occasions when there has been a problem HGST tech support has taken care of the situation.

Terrific Drives

Pros: Super Reliable
FAST- for NAS

Cons: they aren't free

Other Thoughts: I have two of these as a RAID array in my QNAP NAS, love it. If you look at BackBlaze's reports these HGST drives are as reliable as you will find, and I have to say they are indeed very fast for a NAS solution. I run SMART tests twice monthly and performance tests every month. No issues at all. Great drives.
