The Best SSDs and HDDs For Your Money: June 2012: 14 recommended SSDs at or below $1/GB!
The Crucial M4 256GB SSD is recommended as the best SSD for $200, with a price per GB of only $0.78/GB!
The Best SSDs and HDDs For Your Money?
By that, I mean the drives that offer the best performance, reliability and/or most capacity at a given price.
Why would you want that?
Because you want the best bang for the buck, the best possible drive for your hard-earned money and the highest performance, reliability and capacity possible!If you have the time…
Reading SSDs/HDDs reviews are a lot of fun. However, most of us don’t have the time to do the research and just want to know the best option for our budget.
This is where this article comes in, by recommending to you the best SSDs and the best hard drives for your money, at various price points.
Keep in mind:
1. This list is based on the best U.S. prices from NewEgg and/or Amazon that I’ve seen as June 20th 2012. Prices and availability change everyday. I can’t keep up with accurate pricing everyday, but I can suggest to you great drives that you won’t regret buying.
2. All prices are based on new drives prices, no used or open box drives are listed; they might be a good deal but come with trade offs such as limited return policy, limited warranty, etc.
This article is in four parts:
1. The Best Solid State Drives (SSDs) For Your Money
2. The Best Hard Disk Drives (HDDs) For Your Money
3. RAID 0,1,5 and 10: A quick and easy summary
4. Conclusion and future SSDs/HDDs.
The Best SSDs For Your Money:
SSD FAQ:
If you wondering “Who are SSDs for?”, if you want a quick recap on what a SSD is, wonder about reports of SSDs slowing down over time or want to learn more about TRIM and/or TRIM with RAID, I invite you to read our SSD FAQ.
June Update:
14 recommended SSDs at or below $1/GB and many price cuts!
- Corsair: Considering that the Crucial M4 and other SSDs from competitors offer higher performance and/or higher reliability at lower prices, I no longer recommend Corsair Force 3 and Force GT SSDs. As for the Corsair Performance Series Pro line-up, the Plextor M3 and M3 Pro are offered at similar prices, offer similar/better performance and come with a longer 5 years warranty.
- Crucial: Just like in April compared to the February update, the M4 series SSDs all dramatically went down in price compared to April, selling for well under $1/GB and are all terrific deals considering their good performance and high reliability.
- Intel: Intel 330 series: Based on a SandForce 2nd generation controller, with slower NAND than the 520 series, Intel launched the 330 series, with pretty competitive prices. 520 series: The prices on the 520 series went down quite a bit since the last update.
- Kingston: HyperX: All models have gone down significantly in price, with the 90GB, 120GB and 240GB selling for $1/GB! HyperX 3K: Kingston recently launched their HyperX 3K line-up of SSDs, which uses the same SandForce controller as the “old” HyperX SSDs, but 25nm NAND that’s rated for 3K writes, as opposed to 25nm NAND that’s rated for 5K writes in the HyperX SSDs. Even if you write 10GB to your SSD everyday (on the high end for the average user), your SSD will last you over 8 years with 3K writes. Their performance is pretty much identical and considering their lower prices, they are great choices.
- Mushkin: Unfortunately, since the last update, the reliability of Mushkin SSDs took a nosedive. Due to this, I’m no longer recommending Mushkin SSDs for now.
- OCZ: Agility 4: Following the Vertex 4, which offers tremendous write performance, but unfortunately poor read performance, OCZ launched the Agility 4, with even lower read performance. With the current prices which aren’t competitive for its level of performance and OCZ poor reliability record, I’m currently not recommending the Agility 4 SSD.
- Plextor M3: Prices on the M3 models went down quite a bit, while prices on the M3 Pro haven’t changed much since the last update unfortunately. Plextor M3 and M3 Pro SSDs also offer some of the lowest power consumption for SSDs, making them ideal for notebooks.
- Samsung 830 series: Prices on the Samsung 830 series have dropped considerably since April, with the 128GB and 256GB models hanging around $1/GB.
The SSD Comparative Table:
The SSD comparative table allows you to quickly compare SSDs based on capacity, performance, reliability, price per GB and price, which allows you to figure out which SSD is the best one for your needs.
- Ratings are calculated based on website reviews, the wonderful AnandTech’s SSD Tool, failure rates published by Marc Prieur on hardware.fr, customer reviews and specifications. These are estimates, but at worse, they shouldn’t be off by more than one point.
- Read performance weights for ~60% of the performance rating and write performance for ~40% of it, seeing as the average user’s SSD will experience much more reads when loading the OS/programs/games/various data. compared to writes when installing programs/games/working, saving data and the like.
- Note that performance ratings are only comparable for similar capacity. That is, a “7″ 64GB SSD offers similar performance to another “7″ 64GB SSD, but not to a “7″ 128GB SSD. Generally, when comparing SSDs within the same line-up, higher capacity SSDs offer higher performance than smaller capacity SSDs.
- Only SSDs with a competitive Performance, Reliability and/or Price (or $/GB) are included in this comparative table. If a SSD isn’t this comparative table, it’s simply because its performance/reliability is lower or its price is higher than the competition.
- Performance and reliability scores are not related.
- P: Performance, R: Reliability: On a scale from 1 to 10, higher is better. “~” are used to indicate estimates and “?” are used for scarce data. W: Warranty: In years
- You’ll find in Bold: Performance of 8.5+, Reliability of 9+, Warranties of 5 years and a price per GB of $1.20/GB or lower.

Share your feedback on the SSD comparative table
Seeing as the SSD comparative table is a relatively new addition to the article, some of you to disagree with my numbers. If that is the case, I invite you to leave a comment and to respectfully explain why you disagree, using factual data to back up your claims. If I am indeed mistaken, I’ll make you sure to update the data in the table.
Also, if you have any suggestion to improve the SSD comparative table, let me know.
Reliability:
Reliability varies within a brand from one series to another and varies within a series from one capacity point to another. Reliability has more to do with specific series at a specific storage capacity than just brands or series themselves.
For example, do not buy lets say a 180GB Force 3 SSD from the Corsair brand because you heard good things about the brand (Corsair) or the series (Force 3) or the 120GB model. Instead, buy a Corsair Force 3 180GB because you heard good things about that specific model from that specific brand with that specific storage capacity.
This explains why I’ll sometimes recommend some models with a specific storage capacity from a line-up that are reliable but not other models from the same line-up with a different storage capacity that aren’t as reliable.
After all, part of my job is to help you figure out which specific models are reliable and which ones are to avoid. If you have any doubt about the reliability of a specific model that isn’t listed in the table, feel free to ask me in the comments why I didn’t list it.

Same as the previous recommendation, simply with twice the storage capacity.
Updating the SSD firmware
Recommended to get the latest bug fixes and the best performance possible out of your SSD.
Before you start using your SSD, I strongly urge you to update the SSD’s firmware to get the latest bug fixes and the best performance. Make sure to read the instructions available on each update page, in order to understand how to properly update the firmware.
Most SSDs have newer firmware available than the one that they are shipped with, so make sure to double-check your SSD’s firmware version and to update it if’s not the latest.
If you update your SSD’s firmware after starting to use it, make sure to backup your data beforehand, as something could go wrong during the update process and you could lose the data on the SSD.
If you have questions regarding firmware updates, contact the manufacturer or visit their support forums.
If a drive isn’t listed here, it’s either because I am unaware of a recent firmware release or because the drive does not need a firmware update (i.e. it ships with the latest one).

The Best Hard Drives For Your Money
June 2012 update:
Performance
Performance wise, the latest Seagate Barracuda hard drives top the charts, followed by the Western Digital Caviar Black and the Samsung F3 hard drives tied for 2nd and the Hitachi drives in last place. Keep in mind that the performance difference between each hard drive isn’t significant enough to make a perceivable impact in the vast majority of situations.
SATA II 3.0Gb/s vs SATA III 6.0Gb/s: No performance difference for hard drives!
SATA 3.0 Gb/s (SATA II) and SATA 6.0Gb/s (SATA III) refer to the speed of the connection between the drive and the motherboard.
However, the best hard drives reach about 210MB/s (or 1.68Gb/s) in best scenarios. SATA 3.0Gb/s is plenty enough to handle that and for hard drives, SATA 6.0Gb/s does not offer any performance advantage, since the hard drives can’t even max out a SATA II 3.0Gb/s connection.
Only SSDs take advantage of SATA 6.0Gb/s due to their higher transfer rates.
In other words, if you take two otherwise identical hard drives, the SATA III model will not be faster than the SATA II model. SATA III for hard drives is just a marketing scheme 
Hard Drive Failure Rates:
From Marc Prieur, of hardware.fr, here are the hard drives failures rates according to a French e-tailer as of May 2012:
- Samsung 1.23%
- Western Digital 1.63%
- Seagate 1.89%
- Hitachi 3.95%
The failure rates are based on parts sold between April 1st 2011 and October 1st 2011, for returns before April 2012, which represents 6 months to one year of usage. The statistics per brand are based on a sample of at least 500 sales.
Do note that although these numbers don’t paint the complete picture of world wide failure rates, but they are still an interesting sample to look at.
All hard drives and all SSDs are prone to failure though, which is why you should Have a Backup System that you can rely on!
Prices of hard drives: Not much of a change since April
Prices of hard drives have not moved significantly since our last update in April. Whether this is due to higher demand, manufacturers who are making more profits or both, is debatable.
The Best Hard Drives For Your Money:

- It’s fast and inexpensive at 3TB for $155, but it offers below average reliability.
- $195 – Western Digital Caviar Black 2 TB 7200 RPM
– It offers lower performance, but higher reliability than the Seagate hard drives, as well as a longer 5 years warranty. This is why I recommend it as the best 2TB hard drive.
Lower performance/lower power consumption “Green” hard drives, ideal for storing media, backups, etc.:
- $100 – Seagate Barracuda Green 1.5TB
- $120 – SAMSUNG EcoGreen F4 HD204UI 2TB
- $145 – Western Digital Caviar Green 2.5TB
- $159 – Western Digital Caviar Green 3 TB
RAID 0,1,5 and 10: A quick and easy summary
I’ve been asked by a few of you to explain RAID and the different modes in simple terms. In short, RAID consists of combining two or more hard drives (Or SSDs) to improve performance and/or reliability.
While there are other modes than 0, 1, 5 and 10 (1+0), these are the main ones that usually come integrated on motherboards (Not all motherboards support RAID) , so they are the modes that most of you have access to, hence why I’ll focus on these. Let’s get started!
An important note on using RAID for data loss protection:
Hard drives and SSDs do fail and RAID is not perfect. Sometimes, multiple drives will fail at once (Due to a faulty power supply, power surge, etc.). RAID has limits and is not a 100% fool proof solution for data backup.
It should only be used as one of many steps to protect your data, along with a Backup System that you can rely on!
Note:
In most cases, with motherboard’s integrated RAID controller, you must set up RAID within the BIOS and/or disk manager (i.e. Intel Matrix) prior to installing the OS. Consult your motherboard manual for details on how to set up RAID.
RAID 0:
Using a minimum of two drives and as many as you can install (3,4,5,6,etc.), the data is spread across all the drives, basically combining their read and write performance into one ultra-fast array.
The easiest and cheapest option to improve performance, you keep 100% of the combined drives capacity, but if any drive fails, you lose all data.
Important:
The more drives that you have in your RAID 0 array, the more likely it is to fail. You also get diminishing returns as you add more and more drives:
- Two drives, get a theoretical 100% I/O performance gain but double risk of failure.
- Three drives, get a theoretical 50% further performance gain but triple risk of failure.
- Four drives, get a theoretical 25% further performance gain but quadruple risk of failure.
- Five drives, get a theoretical 20% further performance gain and so on…
So you’ll want to avoid putting critical data that you can’t afford to lose on a RAID 0 array or at the very least, you’ll want to back it up somewhere else as well, since this is the least reliable solution, even less than a single drive.
RAID 1:
Using two drives, the second drive is a live backup of the first one, being an exact copy of it.
You lose a bit of write speed compared to a single drive (due to the overhead of copying the same data in real-time to two different drives), do gain read performance (Since the OS can read from both the drives) but you only get the capacity of one of the two drives (Two 1TB drives in RAID 1 =1TB total capacity).
The main pro is that you get a higher level of redundancy/reliability, compared to a single drive.
If one drive fails you do not lose data, you are still able to use the PC, but you will need to replace the drive and rebuild the RAID array before regaining redundancy and data loss protection from RAID 1.
RAID 5:
Requires a minimum of three drives. Unlike RAID 1 where data is identical on every drive, with RAID 5, data is spread across the drives, with parity bits spread across the drives in a way that if one drive fails, the RAID array will continue to function without any apparent change, other than some performance loss.
However, like with RAID 1, if you lose a drive, you’ll need to replace it before regaining redundancy and data loss protection from RAID 5.
RAID 1 vs RAID 5:
Both RAID 1 (mirroring or duplexing) or RAID 5 (striping with parity) offer good data redundancy should a single drive in a RAID array fail. The major difference however can be found in the system performance between RAID 1 and RAID 5.
RAID 5 experiences more heavy write overhead because of the additional parity data that has to be created and is then written to the disk array. RAID 1 does not experience this overhead.
Read performance, on the other hand, is usually better with a RAID 5 setup. This gets even better if your RAID 5 array has more than 3 disk.
RAID 5 read performance increases with more drives in an array because the more drives there are, the more read/write heads there are, and RAID 5 arrays have the awesome ability to read simultaneously from all the drives at the same time.
RAID 1 only has two drives by nature and is therefore limited in the number of read/write heads.
So in short, if all you want is decent redundancy and don’t care that much about performance, RAID 1 will be just fine. If you want more read performance (For faster applications launch, faster OS and game loading) and capacity (since RAID 1 is limited to two drives in most cases and more would be somewhat pointless), RAID 5 is the best out of the two.
RAID 10 (1+0):
However, if you want top notch performance and redundancy, RAID 1+0 (or 10, same thing) is the way to go. Basically, it’s a combination of RAID 1 redundancy with RAID 0 performance.
While RAID 1+0 is possible with two drives, four drives is preferable if you want the performance benefits.
