G.Skill 25S2-64GB 64GB SSD 2.5-inch Hard Drive

This is hard drive appreciation week here at TweakTown, or so it seems. Over the next few days we will have a slew of platter and flash based drives reviewed on the site that are all designed for notebook systems. Yesterday we started off with the Crucial SLC based 32GB SSD and are following it up today with another SLC based drive from G.Skill.

G.Skill is known for their high performance enthusiast memory, but like many "memory" companies, when RAM became unprofitable they looked to broaden their product lines. One area that many of these companies made a straight line for was expanding their flash memory products. This eventually led to solid state drives and ultimately caused the price of these drives to start to fall rapidly.

As it sits now, the score is 10 to 7 in the favor of the consumer. The companies are able to make a little bit of profit on the SSDs and more consumers are able to afford the technology, thanks to the cycle of increased production, decreased costs. Essentially, everything we predicted in the State of Solid State article is happening on the timeline we said it would.

Today we are looking at the G.Skill 64GB SLC drive. The drive is a rebadged Samsung drive like the four we reviewed in various levels of RAID back in June for DVNation.com. The difference between then and now is that the G.Skill 64GB drive cost just a little more than the 32GB model did when that article was written. At that time, the 32 and 64GB Samsung drives were the fastest hard drives available, an area we will cover over the next week after reviewing the latest and greatest SLC and MLC drives to be released over the last two months. Today we are covering the G.Skill FS-25S2-64G in detail; let's have a look and see how she performs.

Specifications, Availability and Pricing

G.Skill 25S2-64GB 64GB SSD 2.5-inch Hard Drive

All of our benchmark software lists the G.Skill FS-25S2-64GB as a Samsung drive without any mention of G.Skill by name. If you have never seen the packaging and the drive came in an OEM system, you may never know it came from G.Skill at all. Some may take offence to this, but since I have already tested the Samsung MCBQE32G5Mpp-0VA00, Samsung's 32GB version of the FS-25S2-64GB, I already know the performance of the drive and don't look down at the practice at all. G.Skill offers this drive in 32, 64 and 128 GB capacities.

When it comes to specifications, the 100 MB/s read speed stands out as does the 80 MB/s write speed. There are other advantages to SSDs besides their high sustained read and write speeds. The biggest advantage over platter based drives is the access times for both read and write speeds along with advanced shock protection and a wide range of operating temperatures.

By using the TweakTown Shopping Channel, we were able to find the G.Skill FS-25S2-64GB for as low as 625 U.S.D. at Newegg. This is lower than the competing Samsung product which lists for 699 Dollars at Newegg. OCZ uses the same drive as their SLC offering and it is listed at 779 Dollars, so the G.Skill version is quite a bargain when compared to others in this category. Going through the list of 64GB drives at Newegg, there are some competing products that may give the FS-25S2-64GB a run for the money. But you will have to check back to see how they perform over the coming weeks.

The Packaging

G.Skill 25S2-64GB 64GB SSD 2.5-inch Hard Drive

Our sample arrived in the retail packaging. As you can see G.Skill places a circle sticker over the capacity size check box you so can clearly see which model is inside of the package.

The side of the package lists all of the specifications.

The back of the package is exactly like the front side.

A small feature lists is shown on the other side.

Once everything is pulled from the package we see that the drive is secured very well in the box and with plenty of room for the accidental shipping company drop.

The G.Skill FS-25S2-64GB

G.Skill 25S2-64GB 64GB SSD 2.5-inch Hard Drive

Here we see the top of the drive and G.Skill's label. The drive is clearly labeled as a 64GB drive which came in very handy when swapping drives around here at the lab.

It is very difficult to show the level of detail of the laser engraving on the bottom of the drive, but it is absolutely stunning.

The side of the drive has all of the mounting holes where they should be located. The drive on top is a standard platter based notebook drive, 9.5mm tall.

On the back we see the SATA and power connectors where they should be. This is important since some users will want to mount this drive in a desktop or server using a backplane.

Today we are comparing the G.Skill FS-25S2-64GB to a couple of other 2.5 inch drives that are either widely used in the industry or previously reviewed here at TweakTown.

Hitachi 7K100: The 7K100 is a 100GB notebook hard drive that was used by several notebook manufacturers. This is the drive that came with my Lenovo T60.

Hitachi 7K500: The 7K500 is the first 500GB notebook drive to hit the market. Unfortunately the drive is 12 millimeters tall and can only be used in a small number of notebooks. A standard notebook drive is only 9.5mm tall.

Western Digital Scorpio Black: The WD Scorpio Black is a past award winner here at TweakTown and we found it to be one of the best platter based notebook drives available. At the time of review the 320GB version was the fastest platter based 2.5 inch notebook drive on the market.

Crucial CT32GBFAB0: The Crucial SLC SSD is one of the early technology solid state drives and will provide a great example of just how far solid state has progressed.

Read Tests

The Crucial CT32GBFAB0 was quite a bit quicker than the G.Skill SLC drive in the STR Read test. If you have already read the Crucial review, you'll know this doesn't exactly carry over to real world performance.

Write Tests

G.Skill 25S2-64GB 64GB SSD 2.5-inch Hard Drive

In write speed the G.Skill was able to keep up with the fast platter based drive and put a hurting on the Crucial SLC drive. In the all important minimum write speed the G.Skill drive showed its dominance against all competitors.

Access time is a where solid state drives excel and here the G.Skill outperformed the Crucial drive by a large margin, even when scaled down to SSD levels.

Write Tests

Passmark Advanced Multi-User Tests

Many users complain that I/O Meter is too complicated of a benchmark to replicate results so my quest to find an alternative was started. Passmark has added several multi-user tests that measure a hard drives ability to operate in a multi-user environment.

The tests use different settings to mimic basic multi-user operations as they would play out on your server. Variances is read / write percentage as well as random / sequential reads are common in certain applications, Web Servers read nearly 100% of the time while Database Servers write a small amount of data.

The Workstation test is the only single user environment and will be similar to how you use your system at home.

G.Skill 25S2-64GB 64GB SSD 2.5-inch Hard Drive

The Samsung version of this drive is considered and sold as an enterprise drive. As you can see, that level of performance has carried over to G.Skill's offering. The G.Skill 25S2-64GB gave us the best workstation / server benchmark scores to date.

Final Thoughts

Let's knock the OEM / ODM thing out first. There are several companies that are selling the Samsung drive, including Samsung. This is common in the computer hardware world and easy to sort out for the end user and hardware reviewer. Basically, what the end user will want to do is, if the product is deserving, purchase the one that has the lowest cost and the longest warranty. Luckily the G.Skill variant has the lowest cost when compared to the Samsung and OCZ drives and by a large amount.

When it comes to performance the G.Skill SLC based drive is the benchmark in which all others should be compared. The drive is fast in all of our benchmarks, a task that is not exactly easy to do, as we proved in the Crucial SLC review. It isn't going to matter if you are running a large database or installing this drive in your notebook, the drive is simply fast and everything you run off of it will benefit from faster load times and overall "snappiness".

The only real downfall is in the price. Just as SSDs are guaranteed to have very low access times, they are also guaranteed to cost more per Gigabyte them their platter based competitors. To extend that, the SLC drives cost a great deal more than the MLC drives but offer a longer lifespan and in most cases faster performance.
