But there is once again a lack of picture and sound quality. Such a reflective panel with weak contrast and extreme viewing-angle dependency doesn't even belong in a cheap device. The two speakers don't exactly call for shouts of celebration, either. A meager selection of ports joins the list. In the year 2012 we can expect a USB 3.0 port, can't we? The Windows installation stuffed full of bloatware makes us even more unsympathetic.( Acer Aspire 2930 Battery )

But if you're looking for an attractive and high-performing multimedia notebook, you can definitely give the EasyNote LS11HR-167GE a chance. Higher quality 17-inchers like the HP Pavilion dv7-6b02eg cost at least a few 100 Euros more.( Acer Aspire 1410 Battery )
Intel SSD 520 series with the SandForce ControllerThe Intel 520 series aspires for the top with its modified firmware and SandForce controller. According to Intel the 520 series stands above the crowd in terms of performance thanks to the extensive testing and optimizing of the controller. In addition, the new models will also offer the usual SandForce features: automatic data compression and 256 bit encoding.( Acer Ferrari 1000 Battery )

The Intel 520 series makes use of synchronized 29F16B08CCME2 NAND chips (25 nm format). According to Intel, the power consumption of the drives is 850 mW (during use) and 600 mW (idle).( Acer AS09B56 Battery )

The new SSDs offer a wide range of capacities: 60, 120, 180, 240 and 480 GB. The 120, 180 and 240 GB models are available in the 7 mm format (our test model was 9.5 mm thick with the removable plastic case - similar to the old Intel 320 SSD).The Intel 520 SSDs have 5 years warranty. Intel seems to believe that the new 520 models are far more reliable than their predecessor (the 510 series - 3 years warranty).( Acer AS09D31 Battery )

The SSD 510 models are relatively expensive: 149$ (60 GB), 229$ (120 GB), 369$ (180 GB), 509$ (240 GB) and 999$ (480 GB). Buyers will be happy to know that the 120 GB model of the new series is available in some shops at a slightly higher price than an OCZ Vertex 3.( Acer BATBL50L8H Battery )

The high-end Intel test model proved its worth in our benchmarks. In the ATTO benchmark, the model placed at the top of our database of previously-tested SSDs. The Vertex 3 (not directly comparable system) can only start to match the performance of the 520 series after 128 KB. The old 510 series can only hold its own in the read test starting at 16 KB.( Acer Aspire 1810T Battery )

The sequential read rates of the test model are as good as that of the OCZ Octane, Vertex 3 or the old 510 series. The write rate of the new 520 SSD is trumped by two other SSDs: the Intel 510 series and the OCZ Octane. The old Intel 510 series is around 6-7% faster (very small difference), whereas the OCZ Octane SSD is miles ahead - 18-38% faster.( Acer BT.00803.015 Battery )

The 4k performance in all the benchmarks was very good; the test model performed especially well during parallel access (Queue Depth). In fact, in this area, the 520 test model left its competition behind in the dust.( Acer LC.BTP01.017 Battery )

The access times of the test model is not so impressive. This is also the case with other SandForce models. We believe that this is due to automatic compression of data on the SandForce drives. The OCZ Octane and Samsung SSD 470 deliver better results in this area. However, there is no clear indication how this affects everyday performance.( Acer LC.BTP01.019 Battery )

Our first test is the copy benchmark from the AS SSD tool: the Intel SSD copied the test ISO file extremely fast. The test model delivered an impressive 368 MB/s - 40-65% faster than other high-end SSDs. Sadly, the OCZ Octane took the lead in the program and game copy tests. ( Acer AS09D34 Battery )

The new SSD scored noticeably lower in the PCMark 7 program benchmark. The Octane is a mere 2% overall and about 4% slower in the System storage test. The old 510 series is about as fast, whereas the old Samsung 470 SSD is overall 7% slower and 12% slower in the Disk test.( Acer AS09D36 Battery )

The PCMark Vantage test showed the first signs of degrading in the test model. When Windows 7 was installed on the SSD, the device could score a meager 45,907 points in the HDD test. The Octane scores 46% higher - significantly faster. However, running the HDD test on a freshly formatted 520 SSD increases the score to a respectable 72,999 points.( Acer AS09D56 Battery )

The measurements from the IOMix and Workstation profiles of the Iometer tool are more reliable: the Intel SSD can reach new highs with a small 10 GB partition. The closest competitor is the Vertex 3, however, as the system of the Vertex 3 is not directly comparable to that of our test model, the Vertex 3 may actually be able to perform faster. On average, the Octane and the SSD 510 series were 41% and 33% slower than the new Intel 520 test model.( Acer AS09D70 Battery )

The program profile of the h2benchw benchmark also attested to the amazing performance of the new 520 series. The test model scored 194.8 points and thus placed itself at the same level as an Agility 3 SSD (also equipped with a SandForce controller). The old 510 series was 8% slower.( Acer AS09F34 Battery )

In addition to well-known benchmark, we also tested with a variety of practical tests to measure the everyday performance of the test model. The SSD can boot into Windows 7 in 28 seconds. In comparison the old Samsung 470 SSD can complete the same task in 30 seconds. The new 520 series was a mere 2 seconds faster in this test.( Acer LC.BTP00.052 Battery )

We also measured the time it took for the test model to load Battlefield 3 in single player mode. The SSD required (on average) 19 seconds to reach the intro video. The older Samsung 470 SSD, the Intel 510 series and the Octane also required 19 seconds to reach the intro video. In comparison, a desktop hard disk requires a long 75 seconds (on average) to load the game.( Acer Ferrari 1003 Battery )

The true potential of the modern SATA 3 SSDs is revealed when copying big files. We copied the game folder of Supreme Commander: Forged Alliance (7.29 GB, 2251 files) in 47 seconds with the Intel 520 test model. This is significantly faster than the old Samsung 470 SSD which required 67 to 167 seconds (depending on the attempt).( Acer Ferrari 1003WTMi Battery )

A special feature of the SandForce controller is the automatic compression of data. The better a SSD can compress data, the faster it is. In the AS SSD compression benchmark, ( Acer Ferrari 1004WTMi Battery )one can clearly see the high performance of the SSD. The old Intel SSD 510 (with Marvell controller) reaches similar values in this test. The new SSD 520 reached 300 MB/s (write rate - not compressed data) to 485 MB/s (perfectly compressed data). Intel claims that most files can be compressed around 60%. This means that the test model should deliver write rates of 400 MB/s or more on average.( Acer Aspire 3100 Battery )

The Intel 520 SSD is well-equipped for heavy use, thanks to "Trim" support and the optimized function of the SSD toolbox, . ( Acer Aspire 3102 Battery )We strained the SSD with the IOMix profile (Iometer tool) for more than 2 hours. The average transfer rates during the test dropped from 230 MB/s to 163 MB/s. In the first hour, the performance drop to an average of 200 MB/s is not worthy of mention. However, at the end of the test, the transfer rate dropped to 100 MB/s. In the AS SSD compression benchmark, the read performance also dropped significantly (with poorly compressed files) to 300 MB/s.( Acer Aspire 3102NWLMi Battery )

We tested the Intel 520 SSD in a Sandy Bridge laptop. We had to use an adapter to install the SSD in the optical drive slot, and this lead to a significant loss in performance. The drive reached a mere 64% of the performance of a SATA 3 desktop (CrystalDiskMark 3). The loss in performance is obvious as the old Samsung 470 SSD scored higher than the test model. In fact, for older systems we recommend the use of older and cheaper SATA 2 SSDs.( Acer Aspire 3102WLMi Battery )

The Intel 520 test model (240 GB version) has proved its worth in multiple tests and time and again, it landed in the top tiers of our database. Intel aims to offset the issues of reliability of SandForce-based SSDs by extensively modifying and testing the firmware used by the SandForce controller. The buyer will have to wait a few months to see how effective this procedure really was. As the controller is already relatively mature, we can conclude that most of the major problems have been dealt with.( Acer Aspire 3103 Battery )

An upgrade to the new 520 series from the older 510 series can not be recommended. The difference in everyday performance is not tangible. Even a few older SATA 2 SSDs can hold their own in certain tests, such as loading Battlefield 3. However, buyers ready to make the switch from a standard HDD to a high-end SATA 3 SSD will find the Intel 520 SSD a delight.( Acer Aspire 3104 Battery )

The Intel 520 series is not cheap. Sadly for Intel, the performance of their new series is not much higher than that of an OCZ Vertex 3. As such, a few shops are selling the 120 GB 520 SSD for a slightly higher price than the Vertex 3, and we believe that they are right in doing so.( Acer Aspire 3104WLMiB120 Battery )

ReviewSpecifications.HP has given its popular Pavilion dm4 the Beats treatment, painting the entire chassis black and giving the keyboard a menacingly cool red backlight. But good looks aren't the only reason to pick up this unique laptop. The HP Pavilion dm4-3090se Beats Edition also sports a fast Core i5 processor, a hybrid hard drive, and, of course, Beats Audio speakers. Better yet, at $899, this machine costs $25 less than a similarly configuredstandard-edition dm4.( Acer Aspire 3104WLMiB80 Battery )

Editor's Note: While our version of the dm4 had a 20GB SSD, HP has since updated the notebook to include a 32GB SSD for the same price.

Design
Click to EnlargeYour eye can't help but be drawn to the Pavilion dm4 Beats Edition's fire-engine red Beats Beats Audio logo in the center of the dm4's all-black aluminum lid. The notebook's hinges sit in dark chrome-lined housings, and a red-and-white Beats Audio lies in the laptop's rear. It's a great look, but the lid quickly picks up fingerprints.( Acer Aspire 3690 Battery )

Like the exterior, the dm4 Beats Edition's interior is all black, but the palmrest has a nicer soft-touch finish. Universal Power Battery Pack Bank for iPhone 4 4sToo bad HP didn't extend this treatment to the lid. The deck slopes gently inward, giving way to the keyboard with its glossy black keys and red backlighting. A chrome power button and a black Web browser launch button rest in the top left corner of the notebook deck. In the right corner below the keyboard sits an unobtrusive black fingerprint reader.Overall, we liked the subtle curves of this laptop's design, but the inside was also a fingerprint magnet.
