In this review PCSTATS will be testing out Seagate's 2TB, 6Gb/s SATA III Barracuda XT hard drive. This 3.5" desktop hard drive features an increased 64MB onboard cache where other 2TB drives only have 32MB and it supports Native Command Queing (NCQ). The Barracuda XT is the performance oriented drive in Seagate's stables, a spindle speed of 7200RPM gives it a healthy maximum sustained data rate of 138MB/s.
The majority of PC users out there have regular mechanical hard drives in their computers, it’s going to be a long time before SSDs replace them. Hard drive companies like Seagate know this and they’re not going to stop improving the technology, with the introduction of the new SATA 3 interface we’re starting to see hard drives to go with it. The first company out the door with one was Seagate, and it’s a big one coming in at 2 Terabytes in size called the Barracuda XT, and that’s what I’ve got for review today.
HDD, SSD oder SSHD ?
Wir haben bereits einige SSD und HDD Reviews auf OCinside.de vorgestellt und testen seit geraumer Zeit die Kombination aus Solid State Drive und Hard Disk Drive in einem Laufwerk - die sogenannte SSHD.
Die Vorteile der SSHD liegen klar auf der Hand: Der Preis liegt um ein Vielfaches unter einer SSD mit identischer Kapazität.
Nun stellt sich die Frage, ob die SSHD zumindest partiell mit einer SSD mithalten kann oder ob sie eher auf dem Niveau einer herkömmlichen Festplatte liegt.
Seagate hat uns die aktuellste Seagate ST2000DX001 SATA3 Desktop SSHD bestehend aus einer 2 TB Festplatte mit 8 GB MLC Speicher zur Verfügung gestellt, die wir uns im heutigen Testbericht genauer ansehen werden.
Seagate 2TB ST2000DX001 SATA3 SSHD Testbericht
storage space is the one thing computers will never have enough of. Yet as hard drives slowly grow into single-digit Terabyte territory, a single architectural decision implemented years ago makes it impossible for most PCs to even recognize HDDs larger than 2.1TB in size! On the PCSTATS test bench today is Seagate's 3TB, 6Gb/s SATA III Barracuda XT hard drive which gets around the 2.1TB desktop storage capacity limitation by creating two partitions (2.1TB + 0.9TB) with the aid of Seagate's free DiskWizard software.
Seagate just released what is probably the largest external hard drive on the market today, a 3TB desktop drive called the FreeAgent GoFlex Desk. Like other GoFlex products it’s, for lack of a better word, flexible. The GoFlex comes with USB 2.0 connection but your can purchase USB 3.0 or FireWire if you prefer. It works on PC or Mac and comes with several programs from Memeo for Backup, Syncing, Sharing and transferring large files. So read on to learn more..
Seagate has now introduced two generations of their Momentus XT solid state hybrid drive (SSHD) which combined the larger storage capacity of a traditional hard drive with the faster transfer rates of a solid state drive. This fusion of technology offered an improvement over standard drives and moved performance closer to a SSD. The third generation is available now, and Seagate is calling this generation the Laptop SSHD or Laptop Thin SSHD, depending on the thickness of the unit.
Seagate's Momentus XT is a 2.5" notebook drive of a half-Terabyte in capacity that stands out from the crowd because it contains 4GB of SLC NAND flash. The NAND flash is used as sort of a 'fast access repository' to store commonly used data, though at 4GB, the SSD portion of this hybrid drive accounts for only 0.8% of its total storage capacity. The two platter, 7200RPM Seagate Momentus XT posts an average read latency of 11.0ms, write 13.0ms. Seagate's 3Gb/s SATA II ST95005620AS drive retails for round $156 USD / £90 GBP and requires no special drivers or software.
Hard drives with solid state cache storage, also known as hybrid drives, have been around for awhile. They are popular with laptop users but until now, those that have equipment designed to work only with 7mm high drives have been out of luck. Seagate's latest SSHD has been redesigned to a smaller, 7mm form factor as well as improved performance. See how it compares to the previous generation Momentus XT drive.
Seagate is certainly one of the titans when it comes to PC storage options - both consumer and enterprise. It makes sense for them to use their considerable infrastructure to make their mark on the SSD market segment - something they've been slow to do. We found performance on our Seagate 600 240GB drive to be very good with the Link_A_Media Devices (LAMD) LM87800 controller handling all the heavy lifting. The specifications of 550MB/s reads and 450MB/s writes were hit without a problem and even on incompressible data, speeds were solid. IOPS performance was very good as well, exceeding the 80,000/70,000 reads/writes by a bit to place in the upper portion of the comparison list...
Solid state drives have come down significantly in price over the last few years, so it's now cheaper than ever to upgrade your PC. While 120/128 GiB units offer the best compromise between price and capacity in most cases, some users may opt for a 480 GiB model instead if extra storage space is required. Today, we are going to look at two of the latest 480 GiB models; the Seagate 600 and the Kingston HyperX 3K.
