Customer Review: A very good drive for the price
Summary: 4 Stars
This is a review of the Hitachi 1 TB Internal Hard Drive (OS02860)
Basic specs are included in the product description. It is a 1TB 7200 rpm drive with 32 MB Cache. It comes in a retail packaging. The drive is in an anti-static bag, and suspended by plastic holders for protection during delivery and handling. It comes with 4 drive screws, and does not come with a SATA cable.
I purchased this drive when it went for $45 on one of those gold box deals. I need to increase the disk storage space for my workstation, so I am playing with a few different ones to see which ones suit my needs best.
What I need are disks for:
1. I need a drive for file storage; require immediate access to these files. I work with a lot of different file types, which include word processing, picture files (JPG, TIF, RAW), video files (SD, HD, mp4, VOB) for text, picture, and video editing.
2. I need a backup of this drive (manual backup) onto another drive (in the same computer); I run it almost like RAID1, but I manually backup these drives.
3. Automatic backup of this drive onto NAS box running RAID1.
This is a very quiet drive. I think this may be a different model than my other Hitachi drives, which are relatively louder than this one (I have to verify it later). It also runs relatively cool at 33 C during these testings, which means that it is less susceptible to heat damage from use over time (one of the primary causes of hard drive failure is overheating).
Firstly, as a single partition, this drive will come out as 931 GB. (You can skip this paragraph if you understand why a 1TB drive is now just over 900GB after installation.) This is due mainly to the ambiguity of the nomenclature. Briefly (and without going too much into the science), electronic memory circuits such as hard drives and memory chip sizes use a binary architecture, and this means that the number of addressable storage locations is based on the power of 2. Therefore, memory sizes are NOT integer multiples of 1000 (or 10^3), but of 1024. This magic number 1024 is based on 2^10 (read as "two to the power of 10," which is equal to 1024), and because this is approximately 1000, the prefix symbol K (or kilo) was used for convenience. Bottom line is that this drive has 10^9 Bytes (or 1,000,000,000 Bytes, which can be termed as one "Giga" Byte), which is 977 x 10^6 KB, which is 954 x 10^3 MB, which is 931 GB. So if you were wondering where the 69 GB of data storage went, it got lost in the math of ambiguous nomenclature.
Bottom line is that this drive is cheap, fast, and quiet (for a 7200rpm drive). If you need to upgrade your desktop computer's hard drive, I highly recommend this drive.
If you would like to see some benchmark results, read on (warning: geek alert):
I formatted the drive into two separate NTFS partitions for speed testing.
Using a disk benchmark utility, I got a pretty linear transfer rate up to 60% of the drive, with an average transfer rate of 99 MB/s. It started to decline down to 65 MB/s near the inside of the platters.

Inner Half of Platter

Using transfer of real files (large files), I was able to get about 43 MB/s write speeds. A 92GB folder took 36 minutes to transfer to this drive. For read speeds, I was able to get 58 MB/s for the same file folder. Though this is fast, it is not the fastest I've seen. For example, I've seen over 80 MB/s read speeds with a Seagate 1TB 7200.11 drive and a WD Caviar Black 1TB. I'm planning on testing this drive under various applications (various RAID configurations, in a NAS box).
Overall, for the price, this Hitachi is a very good drive. It can serve as a very nice drive for primary storage and for backups. For the price, (about 50 each) these are excellent drives. Only time will tell how reliable they are.
