2TB và larger drives may be all the rage these days, but that doesn’t mean 1TB drives should be ignored. Take a look at Western Digital’s latest Caviar blue 1TB drive – it costs less than a 2TB drive and has more than enough storage for most folks. What’s not khổng lồ like? Read our review.
Western Digital’s Caviar xanh line sits between the company’s high-end Caviar Black và the slower value-oriented Caviar Green. The blue drives have very similar performance khổng lồ the black drives on average, except they come with a three-year limited warranty instead of the Black’s five-year (best in class). The đen drives typically have a larger buffer as well; for example, the WD1002FAEX black has a 64MB cache vs. The 32MB cache of our WD10EALX Blue. Compared lớn the Greens, the Blues have a higher rotational speed (7200RPM vs. ~5200RPM) which equates lớn better performance. In essence, the xanh is Western Digital’s bread-and-butter drive.The WD10EALX’s technical highlight is its 6Gb/s interface, which is the latest SATA III standard.

The WD10EALX has an eye-catching xanh label. Aside from that, physically the drive is quite similar to lớn most 3.5-inch desktop hard drives on the market.

The back of the drive has SATA & power connections in addition to lớn four jumper pins. Jumpers are almost never used in modern hard drives; Western Digital does not say anything about their functionality. It is possible they are used for advanced diagnostics at the factory.

The bottom of the drive has an inward-facing green circuit board. This is a common design characteristic of modern hard drives; the circuit board sits against the metal toàn thân of the hard drive và uses it as a heatsink. Another benefit is that the smooth bottom of the circuit board promotes superior airflow; this can be important in the confinement of a cramped desktop case, especially if it sits next to lớn other hard drives.

The Western Digital Caviar xanh is very easy to take apart if you have a T-8 Torx screwdriver at the ready. After removing four screws, the circuit board is easily removed, exposing the inward facing components, and a vibration isolating foam pad.

Western Digital uses a Marvell 88i9045-TFJ2 controller on the Caviar Blue, which is also seen on the 600GB Velociraptor. Paired up with this SATA 6.0Gbps controller is a 64MB Samsung K4H511638G chip, which contradicts the 32MB figure quoted on the WDC spec sheet. Looking at the drive’s reported specifications in CrystalDiskInfo shows 32MB of cache, meaning Western Digital could just be using a larger chip (cheaper in volume purchases) and not utilizing the entire amount.
A lower capacity drive will typically always thua trận to a higher capacity hard drive with the same rotational speed; this benchmark shows no deviation from this rule. The WD10EALX’s 130MB/s average is respectable, however, & on par with Western Digital’s numbers.
Random transfer numbers are more important than sequential, as random reads and writes cosplay the bulk of everyday hard disk activity. The WD10EALX still lags behind though not by a significant margin.
The WD10EALX puts up a good fight here, soundly beating the Hitachi 7K3000 3TB và Seagate Barracuda XT 3TB by about 15% khổng lồ 25% in reads; it gets pushed back to last place when it comes lớn writes, however.
Write latency is a measure of a drive’s responsiveness. The WD10EALX has a noticeably higher average latency than all of the other drives. The other drives in this comparison have a higher data density per platter, so they have an inherent advantage in this area.
These numbers are in line with the other benchmarks thus far in terms of measuring up khổng lồ other drives. The WD10EALX is not slow by any means.
These last synthetic benchmark tests are server-side measurements, forcing the drive khổng lồ respond lớn multiple demands at once. These benchmarks also áp lực NCQ (Native Command Queuing) capabilities and use scaled loads ranging from a queue depth of 1 to 128.

The best way to describe the WD10EALX’s performance is surprising. It handily outperforms the seemingly bogged-down Seagate Barracuda XT 3TB & fends off the Hitachi 7K3000 3TB until the queue depth reaches 16-32, at which point the 7K3000 pulls ahead. The Western Digital RE4 2TB và Caviar black 2TB are untouchable. For a 1TB drive, the WD10EALX did quite well.
StorageMark 2010 is our custom trace benchmark, designed to lớn more accurately simulate the load a typical computer user would place on the drive.
In this kiểm tra we include: playing one 720P HD movie in truyền thông Player Classic, one 480P SD movie playing in VLC, three movies downloading simultaneously through iTunes, & one 1080i HDTV stream being recorded through Windows truyền thông media Center over a 15 minute period. Higher IOps và MB/s rates with lower latency times are preferred. In this trace we recorded 2,986MB being written to lớn the drive & 1,924MB being read.
The WD10EALX does not do well here compared khổng lồ the other drives. These results correspond with the IOMeter 4K write latency tests earlier in this review; latency is the name of the game for this benchmark và the WD10EALX simply isn’t able khổng lồ keep up.
Our next real-life kiểm tra covers disk activity in a gaming environment. Unlike the HTPC trace, this one relies heavily on the read performance of a drive. Khổng lồ give a simple breakdown of read/write percentages, the HTPC thử nghiệm is 64% write, 36% read, the Productivity test is 59% write and 41% read, while the gaming trace is 6% write & 94% read. The thử nghiệm consists of a Windows 7 Ultimate 64-bit system pre-configured with Steam, with Grand Theft tự động 4, Left 4 Dead 2, and Mass Effect 2 already downloaded & installed. The trace captures the heavy read activity of each trò chơi loading from the start, as well as textures as the game progresses. In this trace we recorded 426MB being written to lớn the drive và 7,235MB being read.
The pattern continues – while the WD10EALX is not bad on its own, it’s not competitive with the 2TB and 3TB drives. Notice the 3TB drives take the cake in this, indicating a high platter mật độ trùng lặp từ khóa corresponds with better read performance.
Our last real-life test covers disk activity in a productivity scenario. For all intents và purposes this thử nghiệm shows drive performance under normal daily activity for most users. This chạy thử includes: a three hour period operating in an office productivity environment with 32-bit Vista running Outlook 2007 connected to lớn an Exchange server, website browsing using Chrome & IE8, editing files within Office 2007, viewing PDFs in Adobe Reader, and an hour of local music playback with two hours of additional online music via Pandora. In this trace we recorded 4,830MB being written to the drive và 2,758MB being read.
The WD10EALX muscles out the Seagate Barracuda XT 3TB nicely in this test; the other drives remain ahead however. Despite its second-to-last place finish, the WD10EALX would still be a good choice for an everyday hard drive – as the rest of the benchmarks have shown, its performance is quite respectable in nearly all scenarios for a 1TB drive.
As a two-platter drive, the WD10EALX enjoys relatively low power nguồn consumption for a 3.5-inch desktop hard drive spinning at 7200RPM. The 5.47W idle number is especially impressive; compare this to the 7.56W idle of the Seagate Barracuda XT 3TB. The 8.11W random read number is noticeably higher than Western Digital’s quoted 6.8W but nothing lớn get too concerned over.
Western Digital Caviar blue drives come with a three-year warranty standard, which is what a typical 3.5-inch desktop hard drive comes with. Those looking for a longer warranty period should step up khổng lồ the Caviar đen series, which offer a five-year (best in class).
Western Digital offers an advanced replacement program with its hard drives; they will cross-ship a new drive with a credit card hold.
The WD10EALX is a respectable 1TB drive from a performance standpoint. Although its performance is not on par with modern 2TB và 3TB drives from Western Digital & competitors, it’s not that far off.
The WD10EALX’s Achilles heel compared khổng lồ the larger drives is its higher average latency, which is detrimental to its read & write performance. It also has lower platter density, which hurts its data transfer performance. The differences shown in this reviews would only come out in extreme usage scenarios; for everyday use, most people will not notice a difference.
