Western Digital Caviar Green 2.5 TB SATA III Intellipower 64 MB Cache Bare/OEM Desktop Drive - WD25EZRX

I have 10 western digital and all of them are great. It is not the exception. Fast, huge capacity,good price, etc. I recomend it

My background - very experienced computer user. I have built them from scratch and play around with them all the time.I was excited about the prospect of this drive... energy efficient, SATA 3, 64MB Cache, 2.5 TB - sounds great. Even paid for overnight delivery.Unfortunately, the one I got worked sometimes, not others. Got messages around 'bad sectors'. Could not fix. Worked fine as an externally attached hard drive (most of the time). Did not work at all internally when connected to SATA cables.Sunday, I gave up and bought a Seagate Barracuda Green 2 TB drive at BestBuy. Connected the SATA cables and works flawlessly. I was up and running in less than ten minutes.I have had plenty of Western Digital drives in the past, but, this is my first "dud" from them. So sometimes you get a bad drive. It happens. Not happy about this drive, but, I wont necessarily exclude WD from the future. But, if the Seagate continues to run great, they will be my first choice.I will update this review if the Seagate goes down. (It would only be fair.)

The packaging was suitable for this kind of product.the disk is fast enough for my purpose (archiving).Connecting it to the computer was tricky, though.Have in mind that drives above 2,2TB cannot be addressed as MBR but as GPT.This may cause issues with older bios and MBs (like mine). A workaround is to connect the disk via USB.Windows XP is able to work with GPT through additional software.Windows 7 does not have any issues about that.

I bought the 2.5 terabyte drive and installed it in a 64bit windows 7 box as a data only drive. After booting windows I used the windows disk manager to initialize the drive as a GPT partition. It did so but only reported 280GB. I check the bios and the drive was showing up as a 301GB drive. I wrote WD tech support for help on this and got no reply. So after a couple of days of waiting for a resolution, I tried using GPARTED to create the partitions. GPARTED could see the full 2.5 terabytes, but it would not let me create any new partitions, so I deleted the existing partition windows 7 had created and used GPARTED to re-initialize the drive as a GPT drive. I was then able to create a single NTFS partition using the full drive size.I can't give any opinion on the longevity of this drive, but it does run quite and my transfer speeds were good. The price was great. I only gave this drive 4 stars because the tech support seems non-existent. I hope documenting my experience may help someone else with a similar problem installing these drives as a non-booting data drive.Reducing this to 2 stars. I bought two of these to use as backup drives and the both failed within a year. I would stay away from their green drives.

I purchased this drive based on good experiences with other Western Digital Drives. Unfortunately, this one had problems on three computers so I called WD Technical Support and after several tests it was determined that the hard drive had "too many bad sectors" to complete a low level test of the drive. It is going back to Amazon. I have two other WD green drives that have no problems so this might just be a lemon. Thus, the three stars rather than 1. It is still a hassle exchanging drives.

Overall this is a very good drive. Reasonably fast, quiet, and a very good price in terms of $ per gigabyte. My only complaint is something other potential purchasers should be aware of on THIS AND ANY OTHER DRIVE LARGER THAN 2.2TB in size. Unfortunately "MBR" (Master Boot Record), the venerable tried and true method of partitioning hard drives is limited to partitioning drives no larger than 2.2TB in size. Using MBR to partition this or any other drive in excess of 2.2TB will work, but will result in the drive space in excess of the 2.2TB limit becoming unusable. On this particular drive, by the time differing size calculation methods and system reserve space is taking into account, I paid for approximately 250gb of storage space that I could not initially access.Fortunately Windows (in my case Windows 7) has a built in solution for partitioning drives larger in size than 2.2TB. It is called "GPT" (or GUID Partition Table) and it represents the updated replacement for the "MBR" partitioning method. "GPT" appears as an available partitioning option when using the Windows disk management tool (and I am sure many other 3rd party partitioning tools).All well and good? Not quite. There is another catch. While the "GPT" partitioning method can be read from and written to by virtually any modern motherboard, you will not be able to use a "GPT" partitioned disk as a BOOT DISK unless the motherboard firmware specifically supports it. At the time of this writing (11/12) the vast majority of motherboards currently in use, plus a large number of "modern" motherboards currently for sale here on Amazon (as well as all other retailers) are still based on some form of PC BIOS (Basic Input Output System) and inherently cannot support a "GPT" partitioned disk as a boot drive. To boot from a GPT partitioned disk the motherboard must be using UEFI (Unified Extensible Firmware Interface) as it's control firmware. As time progresses UEFI will become the standard for motherboard control firmware, but for the time being... be aware of buying this or any other hard drive that exceeds 2.2TB in size if your intention is to use it as your system boot drive.

Un 2.5 dans le titre un 3.5 dans les caractéristiques. .... et un 3.5 dans le carton que dire .... limite de l arnaque

I ordered the 2.5TB model WD25EZRX and received the smaller, cheaper and slower 2.0TB WD20EARX. It is now on the way back for a replacement and I'm sure Amazon will sort it out, but best to double check what you receive is what you have ordered! Interesting note is that this model (WD25EZRX) is no longer listed on the Western Digital website as a current model. In fact WD no longer offer the 2.5TB Caviar Green's....Update: received another 2.0TB model, so now no longer likely to be a one-off. This one is obviously also going back.

Für gewöhnlich sind Festplatten mit 7200rpm bedeutend lauter als 5400er. Ich habe eine ältere 7200er mit der WD25EZRX ersetzt und staune, dass diese in keinster Weise einen störenden Geräuschpegel erzeugt und mit der "Lärmentwicklung" einer 5400er mithalten kann. Meine ehemalige Festplatte habe ich in ein externes Gehäse eingebaut, da mich deren Lautstärke weniger interessiert.Zudem ist die WD25EZRX sehr sehr schnell. Ich habe für das Übertragen von ca 1,1TB via SATA II nur etwas über eine Stunde gebraucht. Bei kleineren Datenmengen (unter 1GB, von SSD auf die HDD) schafft es Win7 nicht einmal mir ein Statusfenster einzublenden, weil die Daten einfach so durch die Kabel brettern. In meinen Augen ein Quantensprung in Punkto Speed, Lautstärke und Hitzekompensation.Insgesamt ein sehr zufriedenstellendes Produkt, das seinem Preis gerecht wird.(Würde ich mich noch ein wenig besser auskennen, hätte ich euch mehr zum lesen gegeben :) )

Die Lieferung erfolgte recht schnell. Die beiden HDD je 2,5TB wurden in die Synergy NAS installiert und bin mit der Ausführung sehr zufrieden. Sie erfüüllen ganz die an sie gestellten Erwartiungen. Die Lautwstärke wie von anderen Käufern kann ich nicht bestätigen. Diese Platten sind relativ leise, bzw. sind sehr gut in der NAS gekapselt, aber nicht zu stark, sodaß die Temperatur gleichbleibend niedrig ist , trotz hoher Leistung über mehrer Stunden Dauertransfer von Daten. Auch der Tauschund die neue Synchronisierung war ohne Probleme durchgeführt worden, ohne nennenswerte Geräusche und Temperaturen zu produzieren..Würde die Platten wieder kaufen.

Habe zwei diese Platten aufgrund der guten Bewertungen, des großen Fassungsvermögens und der hoch angepriesenen Technologie gekauft.Eine der beiden gab nach circa 10 Minuten betrieb den Geist auf und wurde nicht mal mehr vom BIOS erkannt. Zurück geschickt und neue bekommen.Die Tauschplatte läuft seit dem Problemfrei, jedoch hat nach circa 1 Monat betrieb (täglich ~5h betriebszeit) die Zweite der ursprünglichen Platten Fehler. Lesen und schreiben geht zwar noch aber sie hängt sich zwischendurch auf und die SMART-Werte explodieren.Nun rette ich meine verbliebenen Daten auf ein paar alte 1T Platten von Samsung, welche nach 2 Jahren noch laufen wie neu...Von daher das von drei Platten (bis jetzt) nur eine Fehlerfrei funktioniert gibts auch nur ein drittel (abgerundet) der Sterne.Schade, für mich war WD immer eine Qualitätsmarke.
