 1 TB per platter from Samsung

In the midst of CeBIT Samsung could be found demoing a prototype of a very unusual 2 TB 3.5 inch hard drive. It only has two platters, each of which is a record 1 TB! Up until now, the maximum density per platter was 750 GB (from various manufacturers).

Even though just a prototype, the drive already had the model number HN-D201RAE. In terms of specifications, Heise reports that it is a 5400 rpm drive with 32 MB of cache and a Serial ATA 6 Gb/s interface. This drive will be the first model in the forthcoming Samsung Spinpoint F6 Egogreen range and should be joined by 3 and 4 TB drives in due course. Samsung didn’t give any precise dates for availability, saying simply that the drives would be out sometime this year.

1 TB, 2.5 inch drive, 12.5 mm

In the more immediate future, Samsung was also showing a 1 TB hard drive for laptop. With just two platters, it will be the first 9.5mm 2.5 inch drive. Note that while Seagate did announce a 2.5 inch 1 TB drive on two platters, it was exclusive to the range of external GoFlex hard drives. The Samsung drive, the Spinpoint M8, has a spec of 5400 rpm, 8 MB of cache and a Serial ATA 3 Gb/s interface. Availability has been announced for April.

 Western Digital buys Hitachi GST

Consolidation of the hard drive market is continuing. After Seagate’s purchase of Maxtor in 2005, now Western Digital have bought the Hitachi storage subsidiary, Hitachi GST (itself historically born out of the IBM storage subsidiary, that was initially a joint venture and then taken over entirely by Hitachi).

The acquisition is for a total of USD 4.3 billion, USD 3.5 billion of which is in cash, with the Hitachi group also obtaining stock in Western Digital worth USD 750 million (10%). Western Digital say that the new company won’t change its name. We don’t yet know if the Hitachi GST brand will still be used or not. In Hitachi GST, Western Digital, who took the no.1 spot on the hard drive market from competitor Seagate in 2010, is getting a brand that is relatively well established on the enterprise and server markets, a sector dominated by Seagate. Hitachi GST was no.3 overall in the hard drive sector in the last quarter of 2010 with 18% of market share (31% and 29% for WD and Seagate respectively). This means that, with this acquisition, Western Digital will now be selling one hard drive in two worldwide!

 Seagate Barracuda XT 3 TB

In July last year, Seagate was the first to launch a 3 TB drive, the FreeAgent GoFlex Desk. It was in fact an external hard drive with a Barracuda XT 3 TB, which hadn’t yet been announced as an internal drive. This has now been done!

The Seagate Barracuda XT 3 TB has an SATA 6 Gb/s interface and a 64 MB cache. Seagate has announced maximum sustained speeds of 149 MB/s, against 138 MB/s for the 2 TB version. This increase in performance can be explained by the higher density – Seagate is now using 600 GB platters rather than 500 GB.

Note that Seagate supplies software designed to get around the 2 Tib / 2.2 TB limitations if you aren’t using a UEFI bios and Windows 7/Vista 64-bit for a boot drive or simply Windows 64-bit for a data drive. Like the ASUS Disk Unlocker , Disk Wizard creates another virutal drive with the drive space beyond the limit supported by your system.

 Tested: Samsung EcoGreen F4 2 TB

We have just added the F4 version of the Samsung EcoGreen to our 2 TB hard drive comparative. In comparison to the EcoGreen F3, this version has a higher density with 3 x 667 GB platters instead of 4 platters at 500 GB. This is also the first Samsung range to adopt Advanced Format 512e.

Hitachi, Samsung, Seagate and Western all have hard drives with 2 TB capacities. What performance do they give? You’ll get your answer in this comparison of 9 models:

- Hitachi 7K2000 (HDS722020ALA330)
- Samsung EcoGreen F3 (HD203WI)
- Samsung EcoGreen F4 (HD204UI)
- Seagate Barracuda LP (ST32000542AS)
- Seagate Barracuda XT (ST32000641AS)
- Western Digital Caviar Green (WD20EADS)
- Western Digital Caviar Green (WD20EARS, 3 platters)
- Western Digital Caviar Green (WD20EARS, 4 platters)
- Western Digital Caviar Black (WD2001FASS)

After announcing its first 3 TB general consumer hard drive, the Deskstar 7K3000, Hitachi has launched the enterprise version of the same product, the Ultrastar 7K3000. Broadly, the spec is the same (7200 rpm, 64 MB of cache) and Hitachi has announced an average access time of 8.2 ms for sustained speeds of 152 MB/s.
While the Deskstar was released in 1.5, 2 and 3 TB versions, only the 2 and 3 TB versions are available here, with the 3 TB model using 5 platters.

Of course, as an entreprise product, the Ultrastar 7K3000 is available in Serial ATA 6 Gb/s and SAS 6 Gb/s versions, with or without data encryption and has been announced with an MTBF of 2 million hours. 600,000 read head load/unload cycles are given, which is the same as for the Deskstar 3 TB but double the lower capacity versions. The error rate is ten times lower, going from 1 in 10 to the power of 14 to 1 in 10 to the power of 15. The guarantee on these Ultrastar models is for 5 years, against 3 for the Deskstars.
