THIS MAY SAVE A LIFE!
A tour bus driver drives with a bus full of seniors down a highway, when he is tapped on his shoulder by a little old lady.
She offers him a handful of peanuts, which he gratefully munches up.
After approximately 15 minutes, she taps him on his shoulder again and she hands him another handful of peanuts. She repeats this gesture about eight times.
At the ninth time he asks the little old lady why they do not eat the peanuts themselves, whereupon she replies that it is not possible because of their old teeth, they are not able to chew them.
"Why do you buy them then?" he asks puzzled.
Whereupon the old lady answers, 'We just love the chocolate around them."
Pregnant Bride
A visitor was strolling along the coastal area one morning. During his walk he came upon a fellow, fishing pole clutched in his hands, sound asleep against the side of a huge coastal rock. Just then the pole began to jerk violently.
"Hey, there!" cried the visitor as he roused the fisherman. "Look out there! You have a bite."
"So I do," yawned the drowsy one glancing out at the water. "If you don't mind, will you pull in the line for me?"
The visitor, somewhat surprised, did as he was requested.
"Now, mister," continued the fisherman, "put some fresh bait on the hook and cast the line out for me."
Again the visitor complied. After doing so he turned to the lazy angler. "You know," he declared, "anyone as lazy as you ought to get married and have a son to do these things for him."
"That's a good idea," beamed the fisherman. "Know where I could find a pregnant woman?"
War is War
Once at the time of the world war, the soldiers were looting all villages, of food, wine and women. Before they could enter one such village, the villagers decide to scoot, except for one young man, who had a 80-year-old grandmother. So the soldiers found the one occupied house and tore inside. "Bring us some food!" they demanded.
The young man said, "But I have only half a loaf of bread."
"War is War, bring us the food!"
So he gives his last morsel of food.
"Bring us some wine!"
"But I doubt if there is any in the house, you know how things are these days!"
"War is War, bring us the wine!"
So the young man manages half a bottle and gives it to them.
"Now, bring us a woman!"
"But everyone has left the village. The only female here is my 80 year old grandmother!!"
"War is War, bring her to us!"
The old woman is brought and she's so frail and weak that the soldiers decide against it and say, "We'll let you off this time.'"
Granny says, "The hell you will, War is War!"
Toilet Encounter
Frank was barely sitting down when he heard a voice from the other stall saying, "Hi, how are you doing?"
He's not the type to start a conversation in the restroom, but he don't know what got into him, so he answered, somewhat embarrassed, "Doing just great!"
And the person in the other stall said, "So, what are you up to?"
What kind of question is that? At this point, Frank was thinking this was too bizarre, so he said, "Uhhh, I'm like you, just traveling!"
At this point he was just trying to get out as fast as he could, when he heard another question, "Can I come over?"
This question was just too weird for Frank, but he figured he could just be polite and end the conversation. He told the person, "No... I'm a little busy right now!!!"
Then he heard the person say nervously, "Listen, I'll have to call you back. There's an idiot in the other stall who keeps answering all my questions!"
Private Secretary
Police was investigating the mysterious death of a prominent businessman who had jumped from a window of his 9th-story office.
Nancy, his voluptuous private secretary could offer no explanation for the action but said that her boss had been acting peculiarly ever since she started working for him, a month ago.
"After my very first week on the job," Nancy said, "I received a raise. At the end of the second week he called me into his private office, gave me a lovely black nightie, five pairs of nylon stockings and said, 'These are for a beautiful efficient secretary.'
"At the end of the third week he gave me a fabulous mink stole. Then, this afternoon, he called me into his private office again, presented me with this fabulous diamond bracelet and asked me if I could consider making love to him and what it would cost."
"I told him that I would, and because he had been so nice to me, he could have it for just 500 bucks, although I was charging all the other guys in the office one thousand. That's when he jumped out the window."
Santa`s Dream
Once Santa kept having the same weird dream everynight, so he went to a doctor.
Doctor: What was your dream about?
Santa: I was being chased by a vampire!
Doctor: (giggles quitely) So... what is the scenery like?
Santa: I was running in a hall way.
Doctor: Then what happened?
Santa: Well that's the weird thing. In every single dream, the same thing happened. I always come to this door, but I can't open it. I keep pushing the door and pushing the door, but it wouldn't budge!
Doctor: Does the door have any letters on it?
Santa: Yes it did.
Doctor: And what did these letter spell?
Santa: It said "Pull"
IMAGINE ONE THOUSAND thousand thousand thousand bytes. A terabyte, if you will. But more than just that―a milestone in storage capacity that hard drive manufacturers have been chasing for years. After more than a decade of living in a world of gigabytes, the bar has finally been raised by Hitachi's terabyte-capacity Deskstar 7K1000.
Being first to the terabyte mark gives Hitachi bragging rights, and more importantly, the ability to offer single-drive storage capacity 33% greater than that of its competitors. Hitachi isn't banking on capacity alone, though. The 7K1000 is also outfitted with a whopping 32MB of cache―double what you get with other 3.5″ hard drives. Couple that extra cache with 200GB platters that have the highest areal density of any drive on the market, and the 7K1000's performance could impress as much as its capacity.
Has Hitachi achieved a perfect balance of speed and storage with its Deskstar 7K1000? We've tested it against nearly 20 competitors―including its closest 750GB rivals from Seagate and Western Digital―to find out.
When a terabyte isn't
By now I've no doubt been heckled by someone insisting that the 7K1000 doesn't actually offer a full terabyte of storage capacity. This person probably sounds like the comic book guy from The Simpsons, but don't dismiss him. He has a point, sort of.
According to the International System of Units (SI), a terabyte consists of 1,000,000,000,000 bytes―10004, or 1012. Windows confirms that the 7K1000 delivers 1,000,202,240,000 bytes, which is more than it needs, so what's the comic book guy on about?
Look a little closer, and you'll see that while the 7K1000 does indeed offer over a trillion bytes, that capacity only translates to 931 gigabytes. For an explanation of why, we have to delve into the always exciting world of numerical systems. SI units are built on the same base 10 decimal system we've been using since grade school. Computers, however, use a binary base 2 system. So, while a kilobyte in decimal is 1,000 bytes, a kilobyte in binary translates to 1,024 bytes. A binary terabyte, then, is not 1,0004, but 1,0244, or 240.
Multiplying that out, a binary terabyte yields 1,099,511,627,776 bytes, which is why the 7K1000 falls short of a thousand gigabytes. The drive would actually need 1,024 gigabytes to achieve terabyte status in the binary world. This translation problem isn't unique to the 7K1000, either. Virtually all hard drives advertise their capacities in SI units, so their actual capacities fall short of binary expectations.
Back in the day, the gap between decimal and binary capacity wasn't big enough to ruffle feathers. Gigabyte drives were only "missing" 24 megabytes, and that was easy to swallow. However, higher capacities widen the disconnect between decimal and binary, leading the terabyte 7K1000 to pull up 69GB short. If you take out multimedia files, 69GB is probably more than enough capacity for what most of us have on our hard drives, so it's hardly a drop in the bucket.
To help ease the confusion surrounding the PC's base 2 binary system, various standards bodies are pushing a set of alternative binary prefixes. A terabyte would remain one trillion bytes, while "tebibyte" would denote 1,099,511,627,776 bytes. Needless to say, that hasn't caught on yet. However, as growing hard drive capacities increase the amount of space "lost" in binary to decimal conversion, the tebibyte's time may come.
The drive
Now that we have the math sorted out, it's time to take a look at the Deskstar. Not that there's much to see.
The 7K1000 looks like just about any other desktop drive. Only a couple of characters on the label serve as evidence of its monstrous capacity. Hard drives don't need to score high on artistic impression, of course, but I'm continually surprised to see manufacturers wrapping their flagship products in the same generic skin as budget models. You'd think the reigning capacity king would have a little more flair, but there's nothing to visually set the 7K1000 apart from other Deskstar models or even competitor drives.

To see what makes the 7K1000 special, you have to dig into the drive's spec sheet. Terabyte capacity is obviously what makes this drive unique, but how it gets there is also important. The 7K1000 uses five platters to achieve its industry-leading capacity, perpendicularly packing an impressive 200GB onto each disk. These 200GB platters give the 7K1000 a higher areal density than competing drives that typically feature 188GB platters, and since higher areal densities can lead to better performance by allowing the drive head to access more data across the same physical area, the Deskstar is nicely set up for speed.
Copious amounts of cache should also help the 7K1000 in the performance department. Serial ATA hard drives typically come with either 8MB or 16MB of onboard cache, but the Deskstar packs a whopping 32MB thanks to a single Hynix memory chip. Hitachi didn't add capacity to the Deskstar by turning the drive into a clumsy minivan, then; they built the hard drive equivalent of an Audi RS4 Avant.
With the 7K1000 breaking new ground in cache size and capacity, it's almost amusing to see the drive hanging onto an old-school molex power connector. Power plug flexibility isn't a problem, of course, and it may actually come in handy for those looking to deploy the drive in extremely large storage arrays, since power supplies typically only come with a handful of SATA power connectors.
A RAID array might be a good idea if you actually have a terabyte's worth of data you'd like to store on the 7K1000. That's a lot to lose, and despite the fact that Hitachi covers the drive with a three-year warranty, that warranty will only get you a replacement drive if yours fails―it won't restore your data.Labels: 1000, computer, gigabytes, hard disk, memory, terabyte
