5.0 out of 5 stars Very fast, faster than SanDisk Extreme, but high power use. 22 Jun 2013
By Stephanie Sullivan - Published on Amazon.com
Be sure to read the last update. The original review is below:

This is the first "Big Name" pure SSD drive from a mainly hard disk manufacturer. Up to now they have all come from memory, chip (Intel) or flash drive (SD, USB thumb drive, etc) manufacturers. Samsung makes more memory, flat screens, and other "stuff) than hard drives, so I put them in the memory/chip manufacturer category. Their SSD's are also excellent.

The drive itself is quite thin. This is the 7mm version and it's also available in the ultra-thin 5mm thckness. It should work well in most ultra-thin laptops. The idle (1W) power consumption is more like a conventional 5400rpm drive so battery life in Laptops and mobile devices may not be helped much.

I'm thinking that in the speed vs power tradeoff, Seagate went for speed. This might be a better choice for a desktop where power savings isn't so important.

I just installed the 480GB ST480HM000 for a client in a Dell Precision laptop. It is a very fast drive. I own a Sandisk Extreme purchased fall 2012 in my own Dell Precision laptop and this drive is noticeably faster out of the box. Both are on Windows 7 64bit with 8GB or better RAM.

My continuing concern with SSD hard drives is the flash memory has limited lifetime with writes. This concern decreases as the technology improves over time and I expect this SSD will be better than the older one in my own laptop.

Installation was simple. I used the (Apricorn DriveWire USB 2.0 to IDE/PATA/SATA Universal Hard Drive Adapter ADW-USB-KIT (Red) to clone the client's old drive. I got the latest version of the EZ-GIG copying software (4.13 at this time). EZGig and Apricorn make the cloning process simple but is flexible for custom layout changes.

The only issue I had in cloning the drive was I needing to change the drive mode in the BIOS to IDE instead of ACHI. After the drive was cloned I was able to install the drive and change the bios setting back to ACHI. This drive was not recognized until I did this.

I'll update this review in a few weeks as the drive gets settled-in on my client's PC.

I hope this helps someone.

Update Aug 17 2013:

The Seagate 600 I installed is still operating well and without the noticeable slowdown that sometimes seems to happen with SSD drives over time. It is operating completely uneventfully.

Update August 20, 2013:

A note about warranty and OEM drives.

I was called today by Bryce Stoops of the Seagate Corporate Escalations Team. We had a good conversation and he clarified Seagate's OEM Policy and how it is supposed to work. What Seagate means by a OEM drive is the drive is sold to a systems integrator like Dell or HP and they have an agreement where all warranty claims go through the integrator. These drives sometimes have custom firmware.

The "bare drives" typically sold by Amazon are not OEM drives. Third parties selling through Amazon may sell them, for example, from a manufacturers excess stock.

This became an issue for me when I had warranty problems reported in my review of the Seagate Momentus XT 750GB ST750LX003. These were eventually resolved, but made it certain that warranty matters when things go wrong.

Seagate drives are great, but on those rare occasions where problems come up warranty matters.

Update: December 12, 2013
My client is still very happy with the Seagate 600. It is still "wicked fast". Power isn't an issue since his huge Dell laptop is rarely used on battery. It's more a desktop replacement.

Other SSD's are out now that are a little faster, little larger, use less power and are a bit less expensive like the Samsung 840 EVO.

Update: December 25, 2013
I noticed the price of the 480GB model has dropped about $70!!! This makes it about $40 less than the Samsung mentioned above rather than about $30 more and much more competitive.

Update: February 7, 2014
I have checked the pricing again and the Seagate 600 480GB model is now at about $342. The comparable Samsung 840 EVO is only about $310 reversing the price ratio by about $32 in favor of the Samsung.

5.0 out of 5 stars Solid SSD performance 15 Jun 2013
By James T. Peeples - Published on Amazon.com
The Good:

Speed. Crazy fast drive, compared to my WD 1TB SATA 6Gbps hard drive:
--sequential reads are 272 percent faster
--sequential writes are 254 percent faster
--random reads are 5,529 percent faster (yes, you read that right--over 5 thousand percent faster)
--random writes are 4,473 percent faster

--small drive, very thin
--seems well made and is a physically attractive unit

The Bad:

After installing the SSD, I had system lockups and general instability. I was able to resolve the issue by changing the BIOS SATA mode from AHCI to IDE. Be aware this unit doesn't play well with AHCI. (For reference, my motherboard is a Gigabyte GA-Z77-D3H.)

Edited to add: after installing Intel Rapid Storage Technology (IRST) drivers, and configuring the SSD to accelerate the system HDD, the system stability issues have been resolved, and the boot time for Windows 7 has been cut down to 11 seconds from the original 23 second boot process. I have also altered my rating accordingly from 4 to 5 stars. I would now recommend this unit to anyone wanting an SSD to speed their system.


The real strength of this size SSD is as a system boot drive, with the OS and a very few of your most frequently accessed programs loaded on it. For most users, it will not be large enough to be a single stand-alone drive for a modern system. However, if you combine this SSD along with a larger normal hard drive, you can get the best of both worlds, the speed of the SSD along with a decent amount of storage for your computing needs.

1.0 out of 5 stars drive will give bogus SMART errors in many motherboards 11 Jan 2014
By D. B Weber - Published on Amazon.com
I am a computer repairman with 42 years experience. I saw the one star reviews regarding SMART errors and decided to test the drive in a handful of systems I had laying about. Yes, some motherboards complained about SMART errors on boot. Strange, one motherboard would not see the drive when booting Linux but saw it in Windows. The SMART capability list says it can do error logging but it doesn't remember the test logs. However, the drive surface tested OK despite SMART errors. So the SMART errors are bogus and Seagate needs to fix the firmware. Asking users to update their motherboard BIOS is just wishful thinking on Seagate's part and runs the risk of bricking the system. So if it works for you fine. If it complains, box it up and send it back. Don't accept a refurbished drive under warranty from Seagate. It will give the same SMART errors.

5.0 out of 5 stars Buy one 20 Feb 2014
By Chris Peterson - Published on Amazon.com

This is one of the least expensive ways to drastically enhance the performance of your computer. Whether you are browsing the web, doing office work, gaming, or developing software this drive has been magic for me so far. I deal with a lot of read/write actions and I/O when programming for work.

I have been able to consistently get 500mb/s throughput out of this drive on my HP laptop. This is at least 20X faster than even the Seagate SSHD that I have (8 GB flash memory SS +750GB hard disk).

I put my old 90GB OCZ Vertex SSD in my wife's 2009 MacBook Pro and it is like new now.

5.0 out of 5 stars Wow! 26 Jan 2014
By Cliff - Published on Amazon.com
Verified Purchase
From a barely functioning PC, to one with the fastest boot and functioning that I have ever seen. All in one installation! The process of installing it is an interesting thing in itself. After doing it for the first time, I discovered that I had been ignoring backup with no apparent motivation other than treating it as a nuisance.

I had to ask for some help to get the right caddy cable. Luckily I had taken a disk image onto DVDs. Without that it would have been awful. Just installing the disk brings up a whole world of options that I was unaware of. Besides the fact that this Seagate has rated as the fastest read and write speeds around is a plus, the process of buying and installing it is the education that raises an awareness of what is possible. Now with dual drives, my HP takes care of backup effortlessly in a way that an external drive cannot (if you remember you are lucky and end up with outdated backups that require a huge recovery exercise to reinstall everything.

Buy one. Do it!
