When compared directly to two of its competitors within the 500GB category, we find the Samsung HD501LJ has nearly identical specs as the Hitachi and Seagate drives. The only major differences is a read seek time advantage and lower power consumption at idle for the Hitachi drive and an additional two years of warranty coverage for the Seagate drive.

Samsung has 17 variations of the T166 product series released at this time with a choice of PATA or SATA interfaces and 8MB or 16MB cache schemes. Capacities for the T166 series range from 80GB to 500GB. Our review unit is at the top of Samsung's model lineup with a 500GB capacity and SATA 3Gbps interface. This capacity is made possible by three 167GB platters spinning at 7200rpm with a 16MB cache. The current street price for this unit is around $109 making it a bargain in the 500GB market. The Hitachi and Seagate drives sell for $139 and $119 respectively.

Feature Set


The external casing design of the SpinPoint T166 series is based on the industry standard 3.5" form factor platform with pertinent part number and warranty information embossed on a white sticker on the top of the casing. Samsung quotes a 600,000 hour Mean Time Between Failure rate that is significantly less than other drives in this category, and near-line enterprise SATA drives that hover around a 1 million to 1.2 million hour MTBF rating.

Of course, MTBF ratings are meaningless if your drive fails within a few hours of operation or a few days outside the warranty period, as is known to happen on occasion. We normally pay very little attention to MTBF ratings and instead focus on the manufacturer's stated lifetime expectancy for the drive and warranty coverage - the longer the better. Samsung lists the life expectancy of this drive under normal operating conditions to be around five years and provides a three year warranty.


The SpinPoint T166 SATA family ships with Serial ATA data and power connectors only. There is no support for the 4-pin Molex power connector designed for use with older ATX power supplies. To the left of the data and power connectors is an eight pin jumper block. This jumper block will determine whether the drive operates in Master, Slave, or Select Cable mode if you are using a PATA model; for SATA models this jumper block has no effect.

The PCB is openly visible on the bottom of the drive as in previous series and contains a Marvell controller chipset and Samsung's own memory module. In the past we have seen Samsung utilize ESMT (Elite Semiconductor Memory Technology) memory which was always surprising given the size of Samsung's memory business.

    All the best ones are. Ever heard of Intel? It's a big company, they go by the ticker INTC. Check them out. Of course, Supermicro is American too, and are the best with Intel in terms of reliability. Fancy them both being American, huh?


    LOL. You're funny! Intel doesn't even make motherboards.

    Of course build quality/reliability has come down over the years (as it has in almost all manufacturing sectors), but this has been done very consciously to lower cost so please don't pretend the U.S. is special in this regard.

    Intel doesn't make motherboards? Is this an episode of the Twilight Zone? How can two people believe this. Well, I must be drugged or something, because I would have sworn I had several Intel motherboards running and about 15 that are part of my collection that are for show.

    Why do you post nonsense that can be easily disproven? Go to their site, I'll help you since you're obviously not too sharp http://www.intel.com/products/motherboard/index.ht...">http://www.intel.com/products/motherboard/index.ht... .

    Fancy that they are just as delusional as I am. At least if I'm insane, I'm in good company (no pun intended).

    I know this is an old comment, but I just had to comment on this one...Intel mainboards are not actually made by Intel...never have been to my knowledge. All Intel mainboards are designed by Intel, however; Intel contracts all manufacturing out to Foxconn.

    Intel boards are really made overseas. People do not realize Foxconn makes a lot of stuff in the computer industry.
  • snor - Monday, July 9, 2007 - link

    Actually, Foxconn produces Intel's motherboards.
  • TA152H - Tuesday, July 10, 2007 - link

    And you are getting this information from where??????

    Pardon my ignorance. Who are these two manufacturers?
  • TA152H - Tuesday, July 10, 2007 - link

    You couldn't get that from the first message?

    Supermicro and Intel. They are widely regarded as the most reliable in the industry, and my personal experience with them does nothing to disprove it. Strangely, my personal experience with Epox is very good too, and they are Taiwanese, but this is not something I have seen widely accepted. So, I guess it's just a fluke. I also don't know what's happened to them. If I were going to buy an AMD based motherboard, I would pick them, but they don't seem to be selling much anymore. Again, I'm pretty sure I was just lucky with them, since they aren't known for reliability. But, sometimes it's better to be lucky than to be smart.

    Just read the Newegg reviews. This Samsung drive is the most highly rated 500GB hard drive on Newegg over Seagate and Western Digital. A company is not going to sell hard drives that are unreliable, maybe your luck is just bad or something.
  • TA152H - Monday, July 9, 2007 - link

    Newegg reviews generally aren't written by people three years after they buy a hard drive. So, it's not too useful.

    I've had this Samsung hard drive sitting in my Newegg cart for awhile, but frys had an awesome deal for the 4th of July where they were selling Maxtor 500GB SATA3 16MB Cache Retail hard drives for $90...it's suppose to arrive tomorrow but damn, now I wish I would have waited and bought this Samsung instead.

    BTW, frys still has the deal going on. http://tinyurl.com/2ozqpr">http://tinyurl.com/2ozqpr

    I've heard the 500GB Maxtor hard drives are rebadged Seagate 7200.10 drives since Seagate bought Maxtor up while ago. I'll find out tomorrow when UPS delivers it.
