Both WD Caviar Black drives also showed strong write performance--the 2TB drive had a write speed of 138.1MB/Sec and the 1TB version saw 133.7MB/Sec. For read speeds, a total of five drives managed speeds that exceeded 140MB/Sec: The WD RE4 2TB lead the pack at 155.8MB/Sec, followed by the WD Caviar Black 2TB (148.9MB/Sec), Seagate Barracuda XT 2TB (147.5MB/Sec), Seagate Constellation ES 2TB (145.1MB/Sec), and the WD Caviar Black 1TB (142.8MB/Sec). As far as CrystalDiskMark's sequential write speeds are concerned, the trend we've seen with the previous tests continues--with the fastest drives being the Seagate Barracuda XT 2TB (142.7MB/Sec), Seagate Constellation ES 2TB (138.4MB/Sec), WD RE4 2TB (138.8MB/Sec), WD Caviar Black 1TB (131.3MB/Sec), and WD Caviar Black 2TB (128MB/Sec). As to the general-purpose drives, the Seagate Barracuda LP 2TB is once again the leader at 116.8MB/Sec. The same five performance and enterprise drives are also once again the leaders on CrystalDiskMark's sequential read test, but they are also joined here by the WD RE4-GP (157.3MB/Sec). As a matter of fact, the top four drives here are all WD drives, with three in particular having standout performance: the WD Caviar Black 1 TB (193.6MB/Sec), WD Caviar Black 2TB (179.8MB/Sec), and the WD RE4 (177.3MB/Sec). No surprises here either with the best-performing general-purpose drive: the Seagate Barracuda LP 2TB had a read speed of 119.9MB/Sec.
