I don't know if SSD is more reliable or not, but the price it is selling now is simply too expensive.

Is that extra speed worth so much money? I don't think so, personal opinion though.
*
Don't you mean the price of buying it is too expensive?

It's not about the sequential read/write performance, which is only about 3x or 4x the best that HDDs can offer. It is the access times, which is about 0.1ms and extremely fast compared to HDD's +10ms times; about 100x difference. For operations that involves tons of random reads and writes, like when on boot, SSDs are very responsive. If it takes you long minutes to boot up or do a virus scan that you would like to reduce by a lot, SSDs can do it.

My Seagate 80GB IDE hdd from 2002 is still functioning!

This make me think about SSD, able to last that long even with no moving parts? hmm.gif

It is more of a QC issue. Theoretically, the NAND storage is good for at least ten years. Most of the failures at this time, isn't related to the actual NAND storage. Most of it is probably due to firmware, manufacturing defects or poor QC.

Agree, however I mean the price gap between SSD and HDD, I cannot justify it by the speed difference.
The price gap is simply too large for people to get the SSD.

Then we'll just have to poison them by making them experience the difference. The addiction to speed might be enough to get them to open their wallets. brows.gif

Which is a safer way of storing photos? In a HDD in a computer or an External HDD? Thanks.

If it's a 3.5", it is probably internal, as you can get a good PSU and you don't move the HDD around. If it's a 2.5", it should handle the stress of being mobile. I'm still using a 2.5" external HDD that is more than three years old.

I purchased the Seagate Barracuda 2TB and 3TB yesterday. And my Windows is installed into an SSD I got yesterday. SSD is awesome. The HDD is so far so good too.
*
You bought them despite the article I had linked reporting that the Seagate Barracuda XT 3 TB had a failure rate of 9.70% and the Seagate Barracuda XT 2 TB had a failure rate of 7.53%? You are a brave man but kudos for sticking to your favourite brand. While I have little doubt that the data in the article is good, it also isn't a world-wide representative nor does it account for changes over time.

I wish you luck. smile.gif

I'm doubtful about Seagate. Their warranty is only 1 year, which I think is too short for a HDD. I may not like warranties but having a warranty this short doesn't sound like they are confident with their product. Then again, I don't like WD Green drives very much with their power saving features but has 2 year warranty so it can be very indecisive on which to choose since we only have 2 companies left in the world manufacturing HDDs. wink.gif
*
When I disabled the Windows setting for HDD power saving, my pair of three year old WD Greens complied without updating their original firmware.

It doesn't matter which manufacturer it was. Very few 3.5" HDDs will survive a proper fall, and it is still chancy even with 2.5" HDDs. When handling HDDs, it is best that you treat them like glass, eggs or any other fragile goods, because they are in fact fragile.

As for repairs, the original manufacturers won't do it for you. For them, it is far cheaper to give you a brand new HDD. For you, it is also far cheaper and quicker to accept a brand new HDD. If you do want to attempt to retrieve the data, you'll need to fork out a lot of money, wait a long while, and still face the possibility of some partially recoverable data or absolutely no recoverable data.

Moving on from this disaster, it would be cheaper to buy two or more HDDs and duplicate your data between the two.

Just a discussion, a "fall down" or "dropped" HDD, shouldn't be the data on the disk itself is still intact? or electromagnetism on the disk itself (that storing the data) will be loss on the disk due to the fall?

As I reckon, when the HDD is not in operation (when carried along), a dropped could means damage the mechanical part of the HDD, as head is parked during idle (non-operation), there shouldn't be any scratches on the disk.
*
Assuming that was true, the data recovery centres are doing a poor job of communicating that potentially crucial information to would-be clients. Then again, it might be to milk the most out of their clientele by not differentiating an easy job from what may be a very difficulty job.

JiesonJason, was your external HDD powered when it fell?

*
The cable alone means nothing. It is the USB 3.0 cable and the USB 3.0 ports on both ends that allows USB 3.0 do its magic. If your desktop or laptop or ext HDD doesn't have USB 3.0, you might as well forget about it until you get replacements or workarounds.

Assuming that you do have the required components, the external HDD should perform about the same as an internal HDD; do not expect miracles.

The problem with HDDs is that they can suddenly fail and all your "precious" goes to the grave with it. Unless you have two HDDs for redundancy (with identical data on both drives). icon_rolleyes.gif

This is the path I choose, two HDDs. It's very convenient to have everything available on disk and not having to mess with hundreds of DVDs. flex.gif

I just hope that my rig won't get electrocuted. blush.gif I should look into a 2TB ext HDD for offline backup.

2TB is equivalent to almost 400 4.7GB DVDs, and you'll probably need more than 400 DVDs to burn 2TB of anime because the files won't fit in nicely. With 3TB, it'll be equivalent to 600 DVDs, and 800 DVDs for 4TB (when they come out).

Actually, I'm also in a dilemma. Initially looking at 3TB drives but I heard that there will be some incompatibility problems with the Microserver. So now looking at 2TB variants. For the same price, I can either get the Hitachi 2TB or the WD Red. I believe warranty wise both are the same. The only thing that is pulling me back is the Red is 5400rpm while the Hitachi is 7200rpm.
*
Ignore the RPM. 5400RPM may seem slow, but it is perfectly serviceable for most needs. Furthemore, gigabit ethernet has a speed limit of 100MB/s, which 5400RPM drives can exceed.

just checked the RE4 price it is very expensive compare to Black. dilemma  sad.gif
I am looking also at blu-ray disk, would the disc be durable for long term storage compare to hdd?
*
Blu-ray is likely to be more fragile than DVD. You know how SSD's write lifespan has reduced as they keep on shrinking the circuitry? Blu-ray has a lot tinier data holes than DVD do. Unless they have some new technique to maintain or improve on the lifespan I wouldn't bet my family photo albums on it.

I would buy the Reds instead of RE4 or Black. Much lower initial cost and replacing failed drives would be a lot less painful. You could buy two Reds for almost the price of one RE4, with which you could RAID-1!

thx for the info.. was thinking to get wd red but many said that in NAS they would perform.. if only for single home use better try seagate 3tb... but 3 years warranty scheme would buy me in...
*
For single home use, high performance HDDs are also unnecessary for a few reasons.
  1. SSDs are far better performers and the capacity/price has become fairly affordable; 120 GB should satisfy most users.
  2. Even if you do not want to buy an SSD for some reason, the average performance HDDs of today are still plenty fast.
  3. You are likely to be bottlenecked at 1 Gbps Ethernet (125 MB/s), USB 2.0 (30MB/s), 100 Mbps Ethernet (12.5 MB/s), 5 Mbps Unifi (0.625 MB/s) and so on.
  4. With multiple internal HDDs or external USB 3.0 HDDs that have similar performance, you could transfer at full speed but you will rarely do it nor need that kind of performance.

The three years warranty and out-of-the-box compatibility for (potential) NAS usage (which is not the average home use) are fair reasons to buy the WD Red. The only remaining issue is the cost.

Hi, does Toshiba DT01ACA Series  suitable for NAS and which is better when compared with WD red.
*
The Toshiba HDD isn't designed for NAS usage.

If you want to buy a HDD for NAS, the WD Red is better. The WD Red also has better paper specifications than Toshiba's HDD.

Funnily enough, the WD Red is also superior to the WD Green in all respects, including power consumption, on paper. Maybe it is due to the platter technology used in the currently available models.

Well, in terms of performance Green should be still better. The reason why Red is better in power consumption, temperature, life time is due to NASware. Don't forget you are paying an extra RM50 on top of the Green drives, and most of the time the Red will spin at 5400 rpm (which contribute to lower power consumption as well)..

Lowest price i manage to find in Penang is RM379 at official WD outlets. For some reason, other distributors and computer shops are selling at a higher price.  hmm.gif
*
Greens spin at 5400RPM too, but WD won't tell you that. smile.gif

And the platter data density has a very strong effect in sequential read/write performance.

http://www.tomshardware.com/reviews/red-wd...nas,3248-4.html

But I didn't know that it had worse access times than the Greens. sad.gif

I guess that is how WD intends to keep the Greens more attractive for non-RAID use. When the Greens gets updated with the same platters that the Reds are using now, the Greens should have better performance than the Reds.

It's quite simple, really. Most of a drive's power is consumed by the motor that spins the disk inside the drive. Reduce the speed of the disk, and you reduce the amount of power required. However, Western Digital doesn't want to say that they're selling 5,400 RPM drives — those became second class in the desktop market years ago. Instead, they rate the drive's speed as "IntelliPower" and take pains to emphasize that there are other factors that affect performance.

Western Digital has caught a lot of flak for withholding the rotation speed of the Green Power, especially when the product was first launched and the marketing material listed the rotation speed as 5,400-7,200 RPM. This led some to speculate that the rotation speed changed dynamically during use — which would have been an impressive engineering feat had it been true. The reality is revealed by a sentence that Western Digital added to the description of IntelliPower: "For each GreenPower™ drive model, WD may use a different, invariable RPM." In other words, Western Digital reserves the right to release both 5,400 RPM and 7,200 RPM drives under the Green Power name — without telling you which are which.

We were able to confirm that our 750 GB Green Power had a spindle speed of 5,400 RPM by analyzing its sound spectrum. Why sound? Sound is vibration; the pitch of the sound corresponds to the frequency of the vibration. Hard drives vibrate at the speed of their motor, so they produce a noise at the same frequency as their rotation speed. Our sample had a sharp spike at exactly 90 Hz (cycles per second). Multiplying that number by 60 (to get cycles per minute) yielded a measured rotation speed of 5,400 RPM.
