I have a buddy with two of these drives to sell, he's asking $225 for both. Put them in RAID0 and watch your computer fly. Drives were manufactured just over a year ago.

Description:
The exploding growth of enterprise data storage puts tremendous pressure on IT managers, who must accommodate ever-greater volume with ever-tighter budgets. This increased need for enterprise storage, coupled with the decline in IT budgets, creates a need for reliable, low-cost solutions. Enter Serial ATA (SATA), a new interface developed with enterprise storage in mind. Some hard drive companies design desktop-class hard drives with the SATA interface, but WD is going one better. To meet the demands of enterprise storage, Western Digital is the only company to combine an enterprise-class hard drive with the SATA interface to meet all the demands of the enterprise environment—reliability, performance, and reduced cost.

A NEW BREED OF HARD DRIVE
Serial ATA is poised to replace Parallel SCSI in the mid-range, but only if there's a drive that can meet the performance and reliability requirements of that market. That drive is the WD Raptor! The WD Raptor is a new class of hard drive that matches SCSI performance and reliability and provides simplified connectivity, all at up to 30 percent less cost than Parallel SCSI drives.

WD RAPTOR PRODUCT BENEFITS

Built for speed, the WD Raptor has 10,000 RPM rotational disk speed and 5.2 ms average data seek times.
Built for reliability, it has a rugged, enterprise-class mechanical platform with high-end bearings and actuator.
Built to last, this Enterprise SATA (ESATA) hard drive is made for years of high-performance operation around the clock. MTBF has been calculated at 1.2 million hours.
Built with a backing, WD Raptor ESATA hard drives carry Western Digital's five-year warranty.
Built for value, WD Raptor is priced up to a third lower than Parallel SCSI enterprise hard drives.

Are they used?

Yes, they're used, and I just finished testing them - they're both working 100% with 0 bad sectors.

Why so much for a used drive?

JoeBoomz
05-21-2005, 12:29 PM
Tell me what YOU think they're worth.

Jim Jones
05-21-2005, 03:07 PM
Considering they are $149 new at memex I think $115 - $120 would be more realistic.

JoeBoomz
05-21-2005, 03:32 PM
Hmm, my bad, I didn't check MemEx's price because OEMDepot usually beats the shit out of them for pricing.

So at MemEx you'd be paying ~$160 (after Tax). We'll call these ones $130 each or $250 for both - that may be a bit more fair for everyone involved.

Raptors don't really devalue that much because they're a very unique part (as far as hard drives go) and they have a 5-year manufacturer warranty. At a MTBF longer than 135 years, the drives really never die. I've gone through a ton of them and have yet to see one dead.

I'll admit the original asking price was a bit unreasonable and apologize to everyone.

Now are you interested in picking one up Jim? :)

You sure you gone through a ton of them?? I went through two WD Raptors and both of them died a nasty death. The troubles to get replacement/warranty on these are not worth the hassle...

Personally, I will never buy a WD again.

where did u get them from?
i also heard that WD has a higher failure rate than seagate to my surprise, this drive really seems interesting in raid

killer drives very fast and reliable woth every penny good luck

I think I'm going to stick with 15K SCSI drives. Thanks.

Sorry be a little off topic, hope this is OK to post (delete if not) as I am looking to get 2 x Raptors (albiet 74GB ones)...

But anyone know when the next generation/size of Raptors are coming out?

Gah, those things are too loud for me. The Raptors run nice and quiet.

I haven't heard anything on a newer bigger Raptor, sorry. I'm running 2 74's right now in RAID0 and they're superb drives. Quieter than the 36's and slightly faster.

I couldn't tell you where he originally picked the drives up from, my guess would be either Memory Express or OEMDepot. Those two places usually have the best prices.

I'm positive that I've gone through a ton of these ;) I've worked with 4 different companies in the past two years as a technician (between moving from Edmonton to Calgary and finding a company that makes me personally the happiest) and each of them sold tons of Raptors. Looking at the return/RMA history, these drives fail very rarely - I'd go so far as to say you may have some issues with your power supply or something that killed both of your drives. I have no reservations about putting these drives in RAID0 and trust my data to both drives. I'd agree with you that WD had a bad run of IDE hard drives when the 120JB's first came out but overall they have a decent product. I hold firm that the Raptors are the best hard drives on the market though ;)


All THAT said, cmon, someone give these drives a good home ;)

Haha, yeah but the bunker is sound proof.

Becuase it seems to me that this statement could be misinterpreted - I would like to make it clear to any potential purchaser that the theoretical MTBF (mean time between failures) of 1.2 million hours for these drives does not mean in any way that they will last for 135 years. I believe you need to look at a drive MTBF with its intended service life (typically the warranty period) which should be five years for this drive. Then you would be able to say that if you replaced the drive every 5 years with another - theoretically it would take 1.2 million hours (136.89 years) before you would experience a drive failure. That being said - The raptors are the most reliable SATA drives that you can buy.

We're these drives purchased with 90 day OEM warranties or the full five year warranty?

JoeBoomz

Thanks for the clarification on MTBF. The fact that WD is willing to warranty these drives for a 5-year period indicates that they're confident in the drives' construction and that they expect very few, if any, failures.

I'm 99.99999% sure these drives do have that 5-year warranty (I haven't heard of an only 90-day OEM warranty available on the Raptor drives), I'll check the drive serial numbers myself next time I'm at the shop to verify that they do have the 5-year on them and will let you know here.

JoeBoomz

I stopped by the shop tonight and checked the serials while I was there. Both have the 5-year warranty on them and are covered until 2009. Crazy.

Bump.

Sorry guys, I was away and the PM box filled right up. If you tried sending me a (DECENT) offer but couldn't please try again now. These drives are still available.

Buddy wants these gone. $225 for both. Interested parties please PM me.
