And the one on the left is the Caviar Black, of the dull green ancestry)<\/p>\n<p>The Hitachi 2TB 7K3000 drive boasted the highest-density 667GB platters for most of last year, when the rest of 2TB drives used 4-5 platters rather than 3 as this one.\u00a0 It even features higher-density platters than the 3TB version which uses five 600GB platters.<\/p>\n<p>This specific drive is still one of the most attractive 7200rpm 2TB drives when it comes to several features that other drives currently on the market do not offer:\u00a0 3-year warranty, relatively high overall reliability due to consumer reports, 64MB cache, only 3 platters of high density for faster sequential reads and writes, better compatibility with WinXP and legacy BIOS motherboards, and an attractive price tag.\u00a0 The fact that it uses only 3 platters means that the drive has less moving parts and heads, which usually translates to lower internal friction or heat output affecting operating temperatures, less noise due to less moving parts, and higher overall durability.<\/p>\n<p>&nbsp;<\/p>\n<p>HGST (Hitachi Global Storage Technologies) provided a data sheet with some specifications for the 7k3000 series, here:<\/p>\n<p><a href=\"http:\/\/www.hgst.com\/tech\/techlib.nsf\/techdocs\/155901D3B251D9A9862577D50023A20A\/$file\/DS7K3000_ds.pdf\" onclick=\"_gaq.push(['_trackEvent','download','http:\/\/www.hgst.com\/tech\/techlib.nsf\/techdocs\/155901D3B251D9A9862577D50023A20A\/$file\/DS7K3000_ds.pdf']);\" >http:\/\/www.hgst.com\/tech\/techlib.nsf\/techdocs\/155901D3B251D9A9862577D50023A20A\/$file\/DS7K3000_ds.pdf<\/a><\/p>\n<p>However, many still wanted more specific information as to the number of platters used.\u00a0 More importantly, many owners felt betrayed by a hard drive utility program reporting only 32MB cache rather than 64MB as Hitachi stated.\u00a0 The good news that will finally put this suspicion to rest is that the specific utility program, CrystalDiskInfo, was updated to version 4.6.2, and now discloses the buffer size as &#8220;Unknown&#8221;

proof enough &#8211; as to how many platter sides the drive actually uses.\u00a0 First, before diving into the details, here&#8217;s a snapshot of the hard drive information shown by HD Tune:<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter  wp-image-30775\" title=\"4\" src=\"http:\/\/i2.wp.com\/alienbabeltech.com\/main\/wp-content\/uploads\/2012\/07\/4.png?resize=356%2C313\" alt=\"\" srcset=\"http:\/\/i2.wp.com\/alienbabeltech.com\/main\/wp-content\/uploads\/2012\/07\/4.png?resize=356%2C313 594w, http:\/\/alienbabeltech.com\/main\/wp-content\/uploads\/2012\/07\/4-300x263.png 300w\" sizes=\"auto, (max-width: 356px) 100vw, 356px\" data-recalc-dims=\"1\" \/><\/p>\n<p>(by the way, like CrystalDiskInfo, it shows &#8220;N\/A&#8221;

to &#8220;full&#8221; here, so that there&#8217;s a more thorough testing of the drive:<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter  wp-image-30777\" title=\"6\" src=\"http:\/\/i1.wp.com\/alienbabeltech.com\/main\/wp-content\/uploads\/2012\/07\/6.jpg?resize=394%2C302\" alt=\"\" srcset=\"http:\/\/i1.wp.com\/alienbabeltech.com\/main\/wp-content\/uploads\/2012\/07\/6.jpg?resize=394%2C302 563w, http:\/\/alienbabeltech.com\/main\/wp-content\/uploads\/2012\/07\/6-300x230.jpg 300w\" sizes=\"auto, (max-width: 394px) 100vw, 394px\" data-recalc-dims=\"1\" \/><\/p>\n<p>\u00a0Then place a check mark in the box for &#8220;Short Stroke&#8221;

only reaching 32 degrees Celsius at the most, it still runs about 1-2 degrees hotter than the Caviar Black.\u00a0 Heck, 32 degrees still makes it one of the coolest drives that I have ever had my hands on (out of dozens of different 7200-15000rpm drives in my possession)!<\/p>\n<p style=\"text-align: left;\">Regarding RAID compatibility &#8211;
