Reactor Final Thoughts

The Corsair Reactor R60 has the makings to be a very solid entry level drive for a very low price. Currently, some retailers are selling this drive for $104 with Mail-in-rebates, or $134 without. It still outperforms contemporary drives without breaking the bank, helping SSDs finally ease into the lower price segments of the market where they can keep dropping prices and increasing performance.

This "solid entry level" SSD also has its share of problems. Many users complain of the drives not showing up in BIOS or disappearing after restarts and requiring multiple shutdowns to be seen again. Others users accuse the Corsair Reactor of silent data corruption; this includes myself. The first drive I received slowly corrupted data, eventually damaging my Windows partition beyond repair. What is worse is that this problem is difficult to diagnose due to its already mentioned silence. Even on CHKDSK or in the S.M.A.R.T. data, errors refuse to reveal themselves. The signs I received were programs not starting and requiring re-installation, BSoD's, Windows needing repair, and documents no longer opening or having massive errors in them.

Corsair R60 Conclusion

For the price, the performance is good. It may not keep up with the likes of the SandForce controller, but even the cheapest of those drives starts at a price $70-80 above the Corsair Reactor R60. And yet this drive still outperforms the traditional storage in random reads and writes by a good amount with 4K reads in the 17MB/s range and writes in 15MB/s range. This drive has quite good sequential read speeds at 240MB/s, and its sequential write speeds at 108MB/s. This leaves things to be desired, but who can complain with that price?

I find the appearance to be a moot point as this drive will be going inside your system hopefully never to see the light of day until it is replaced, but I really do enjoy the dark brushed aluminum look they gave this drive. It's not too flashy and would fit perfectly inside of a Corsair 800D case.

With no moving parts that can be damaged by drops, the metals used to encase it can be thinner and therefore lighter. For those of us used to dealing with Traditional hard drives, they may feel flimsy, but in my time dealing with it, I found it to be very sturdy. If problems do arise, Corsair has quick and efficient customer service on both its website and forums that will take care of you and your drive throughout its 3 year warranty. If you prefer to deal directly with real people, you can even call their customer service (888-222-4346), and they will gladly help you resolve your problems.

Functionality is as it should be: it provides extra performance in day-to-day life over traditional storage but is priced to fit in the mainstream market.

The value of this drive at its current price of $134.00 ($104 after rebate for a limited time) makes this a great entry level drive, but its flaws with silent data corruption and not being able to be detected by the BIOS really hurts it. One of the positive things is that the Corsair kit includes a 2.5" to 3.5" conversion system so that it is easy to mount in your existing 3.5" drive bays without spending extra money.

If Corsair releases new firmware that corrects the data corruption issues and helps with the data disappearance act this drive does, then it really could have an entry level winner on its hands, priced aggressively, and hopefully bringing Solid State Drives to the masses at last.

Hi Austin, good review. Unluckily for Corsair, I never consider their SSDs as a good option because their drives don't match the price and/or performance of the competition.
On the Cons you mentioned low 4k speed, and I think for whoever wants to buy a SSD for OS, 4k read/write performance is the key to achieve better speeds.
At the value, you gave a 6.0, but in the conclusions it says it has a pretty good entry cost. Shouldn't the BIOS and performance issues affect directly on the performance and functionality scores? Or why did you put a 6 on value?

I took into consider the issues in almost all of the points. I feel that as customers buy this drive for storage of OS and most likely important files (although you should always have a backup) that the value of the drive is greatly diminished if it cannot do that function regardless of speed.

Hello, nice review as usual!
May I recommend you also test both the OCZ Vertex LE (Limited Edition) and the Vertex 2 ?

This was Austin's project, but I am presently testing the 120GB OCZ Vertex 2 SSD.

if it is not asking too much could you also test in parallel the Vertex LE (Limited Edition)?
This because there are many confusion around the web and although they seems to perform similar it would be nice for the customer to understand which one of these two is the fastest!
I trust Benchmarkreviews!!

But some of you know good Raid controller optimized for SSD and Trim commands similar to the SSD or not to spoil them in time??

Hmmm.. The purpose of a disk drive is to reliably store and retrieve data. If it corrupts data, it fails on its fundamental purpose. WHo cares about performance at that point. I'd have had a difficult time giving the drive a score any higher than a 1 unless the eval unit was defective out of the box.

Page 10 of 11 needs some serious editing... :(

Also.... a hard drive that corrupts your data? How does that deserve a 7? Did you contact Corsair about that? What did they say?

I did and it was replaced, my secondary drive as of now has not had the errors, but only time will tell if this drive also has problems. I feel that give a drive a completely terrible rating based on one personally experience is bad, but that the issues should be known and taken into consideration. I plan to keep updates going if further problems are found but for now this drive seems to be doing well, although I continue to have occasional BIOS problems.

7 Points - A bad joke.

The Corsair Reactor R60 SSD is definitely unable to work in a professional environment. I had one and only got problems with the non-detection by BIOS after reboot bug. After readings this article, i know that i had the data destruction, too. I didn´t recognized it, i always thought the errors i got were Windows or Software bugs. An ureliable hard drive is a piece of very expensive junk.

A rating of 0-1 would be adequate, until Corsair admits the bugs and fix them with a firmware update or callback of the defective drives.
