Product delivered is not a working piece Kindly give the number of the customer service so that i can contact for warranty claims

It is just stopped working after a few months

Potrzebowałem średniej wielkości dysk do domowego NASa, ten miał oceny i opłacalność. Wydaje mi się, że jest trochę głośniejszy niż sugerowały opinie, ale to nadal lekko zauważalne pyknięcia.

いつ届くのか、やや心配しましたが、ちゃんと届きました。NASへの設定は簡単にできました。動作音も気にならず、静かに動いています。

الهارد جميل جدا جدا ومستورد وأفضل بكثير من الهاردات المحلية

Works great- The best brand ever

I hate to review components like these until I've had them a long time, but now is probably the time for harddrive buying in general. First of all, to those who are wondering, no the 5640 RPM is not a typo. The official specs sheet says that's what it runs at. I think this helps it find a better balance between 5400 RPM power efficiency and 7200 RPM responsiveness. It claims to run cool and it does seem to do so. One lucky surprise is that it's quiet. A lot of larger harddrives intended for NAS or other RAID systems don't really try to be that quiet. According to the spec sheet it's officially 24dBA idle, 28dBA access. That's insane. I can't measure it with digital precision, but I can say it's one of the least annoying sounding drives I have used in a long time. Even many 5400 RPM 2.5" harddrives bother my ears these days (SSDs have spoiled me!) It doesn't seem to have quite the same "whoosh" sound of the actual platters spinning that normally bothers me if a drive is at all close enough to hear. (How did I survive harddrives in the 90s??? I don't know!) This thing is almost whisper quiet and putting my ear right up to it can still make it hard to hear. I think maybe the 5640 RPM contributes to this — likely it strikes a better balance in regards to sonic properties. My best guess is vibrations don't interfere with each other as much or something to that effect. And even the "grinding" when it's accessing data is quieter than most. I went ahead and wrote this review now in part because I just really want to emphasize how much quieter this drive is compared to most. As another piece of good news, this entire series is made with CMR — that is classic magnetic recording — rather than SMR (shingled magnetic recording.) A lot of larger drives in this sort of range use SMR because it's cheaper, but it also is significantly slower on any writes bigger than the cache size — which is probably going to be any decent sized transfers at all. I also see a lot of claims that SMR drives last significantly less actual usage hours (which might make sense since they must rewrite every single block that changes for even a small write.) Right now I have more confidence in a CMR drive to hold up past the 1.5 year mark that seems to come up a lot in reviews and complaints for SMR drives. Speeds did dip down to something like 160MB/s for the final average (instead of the 215MB/s in the specs) for a huge transfer operation, but all in all this drive strikes a lot of great balances. Only time will tell on reliability, but this is a good line.
