We have run busTRACE 8.0 and selected its feature to 'Send a single CDB to a storage device.' What follows is a description of the commands that we sent and actual screenshots of the data that is returned from the drive. To help you better understand the benefit of this capability, we have hooked up an Hitachi SAS 36GB hard drive to our LSI PCI Express SAS Host Bus Adapter. You can simply click on one of our many predefined CDBs or build and send your own user defined CDB. Many powerful features, included with busTRACE 8.0, is its ability to send any Command Descriptor Block (CDB) to a storage device. Click here for details on our latest busTRACE version. Р’В® More Drive Reviews.This web page refers to our older busTRACE 8.0. However, its low-cost Deskstar sibling looks incredibly tempting. This Ultrastar drive is horribly expensive and delivers little in return. ThereРІР‚в„ўs no way we can recommend a drive that we havenРІР‚в„ўt seen, but we reckon the 2TB Deskstar would be worth a long, hard look. Going out on a limb, we have to think that the 2TB Deskstar drive will deliver performance that is very similar to the Ultrastar yet the price is much, much lower, undercutting the WD Caviar Black by a startling Р’Р€95. The Hitachi has lower idle power draw than the WD, but you have to assume that an Ultrastar in a server environment wonРІР‚в„ўt be doing much in the way of idling if it's working for its living. In all of those respects, the Ultrastar looks fairly limp next to the WD Caviar Black. This leaves the 2TB drive as a storage drive where performance is less important than it might otherwise be and the focus shifts to noise levels and price. If youРІР‚в„ўre looking for speed РІР‚вЂњ and who isnРІР‚в„ўt? РІР‚вЂњ you really should have an SSD for your boot drive. The question is how much emphasis you put on the performance of your hard drive. Take all those tests together and the Hitachi comes out as the loser in terms of performance but the margin of defeat varies depending on the type of task you are performing. On the write side of things, the Ultrastar holds up its end in the sequential write test but in the 512KB and 4KB tests it falls behind significantly. The classic synthetic HD Tach 3 benchmark test shows the Ultrastar in a good light with an average read speed that nearly matches the Caviar Black and an average write speed that is faster than the WD drive.Р”В¬rystalDiskMark delivered more nuanced results, with a gap opening up in the three read tests that show the Hitachi to be slower than the WD. We also dragged the 2TB WD Caviar Black out of the cupboard for some back-to-back tests.

We tested the Ultrastar using a Core i7-based PC running Windows 7 Professional. You have to wonder about the value of that extended warranty as current trends suggest that a replacement 2TB drive will be worth pennies by 2014.Р”Р„nd, as it happens, WD offers a five-year warranty on its desktop Caviar Black drives. The Ultrastar, however, gets a whopping five-year warranty. One figure we can easily understand is that the warranty for Deskstar is three years. The WD Caviar drive only uses four platters and it's noticeably more quiet than the Hitachi when running. The nominal capacity of 2TB yields a true 1863GB once the drive has been formatted. The hardware in both the Ultrastar and Deskstar drives is essentially the same, with five platters and ten heads, 32MB of cache, a 7200rpm spin speed and a 3Gb/s Sata interface. It makes the Deskstar look amazingly cheap, while the Ultrastar appears to be rather expensive. If you find a 2TB Caviar Black on sale for Р’Р€169, you can be sure it's the old version with 16MB of cache, but the difference between what Hitachi and WD are both now charging seems ridiculous. To put that in context, the 2TB WD Caviar Black drive with 64MB of cache cost Р’Р€204 at launch and has actually risen slightly in price since then to around Р’Р€215 now. Imagine our shock when we discovered that the Ultrastar sells for a pricy Р’Р€243 while the Deskstar has a tiny price tag of Р’Р€130. Imagine our mild surprise when we opened the box Hitachi sent us and found a 2TB Ultrastar A7K2000 rather than the Deskstar 7K2000 that we had expected. That statement may have been accurate, depending on your definition of РІР‚ВshippingРІР‚в„ў, but we received a 2TB 7200rpm WD Caviar Black - reviewed here in September, and it has taken Hitachi this long to deliver its own 2TB drive.
