Toshiba 4TB Enterprise Internal Hard Drive – MG Series 3.5" SATA HDD for Server, Storage, 24/7 Operation, Hyperscale, Cloud (MG04ACA400E)

Hard drives work as intended. However, I'm not entirely sure if they will last as some of them came with broken plastic covers. Clearly took some abuse before packaging and in transport. Hope it will not impact their long-term performance.

I purchased 5 of these HDDs, all arrived DOA. And later I noticed a Used HDD always became available on the listing when I returned mine... Then I started to check the serial numbers and realized I received the same previously known bad HDDs. More than once. Do not by USED HDDs here.

I use it as an external drive. Far cheaper than the equivalent size in made for external use drives.

Noisy. But, It has the capacity that I want and the speed that I want. I Transferred over 12 TB in less than a day and have indexed all the files and created numerous sub folders. It formatted and connected without any problems.

It vibrates noticeable when on a large wooden table. It gets warmer for my expectations and it does work flawless! What I don't understand is why there is no Toshiba label like in the Amazon picture. The label is like off brand, like I would print myself if not motivated to a better label. Kind of shocking but then again what do I care about the sort of a label, my worry is reliability, ability to read and transfer data with no mistakes. Windows 10 I use (x32 bit) is definitely not up to the task, though. Sometimes I think that Windows 10 is not the best to transfer data but the hard drive is flawless!!! I switched to win 10 x64 and had no problems at all, except for windows 10 being too over protective (good luck trying to disable the antivirus (successfully) on windows 10 x 64). Why does it vibrate? Motor, materials and the hard rubber standoffs. I put it into an Amazon enclosure and the vibration vanished (although the enclosure itself has problems with weak fan and rubber standoffs). I purchased a temp reader on Amazon to have a better understanding of operating temperature. With that type of disk size one must be vigilant but I never had a failed Toshiba drive yet and certainly don't expect it with this hard drive. Thank you Toshiba and Amazon!!! Incredible quality. Thank you Amazon and Amazon delivery person/system!!!! Jan 23 2024 I made few corrections to the text above, Windows 10 x64 works very well, that unswitchable sob antivirus keeps interacting, tried everything; the Toshiba hard drive is FLAWLESS (have I said FLAWLESS?). I purchased a 3.5" hard drive travel/storage case on Amazon and I am glad I did: while travelling, I kept praising myself for not being cheap and buying the protective case, the name is Orico, please look it up on Amazon, well worth the money even if you don't travel, for travellers it is an absolute must have. Again, Toshiba hard drives, all of them are the best quality, I have never (have I said already NEVER?) lost a Toshiba hard drive and have a whole tub of NotToBeMentionedByName hard drives, everything you can name is in that sorry tub-RIP, kept for historical purposes. Yes, you bet, I keep trying to advertise the Toshiba Hard drive, no matter what capacity; they do always work- have I said, FLAWLESS???

Normally I use the N300 series but my latest NAS devices is not compatible with them. These however, it is. This is a new attempt for me and have no real experience with these drives but based on the amazing success of the N300 NAS drives, I bought these with confidence and so far, loaded no problem, formatted, configured RAID 5 and copied 20TB onto them as a test and so far so good.
