Solid-state disk OCZ ARC 100 with capacity of 240 GB: review and testing

At the present moment the segment of solid state drives is full of all sorts of drive models. Many IT-companies have lineups of SSD-drives of various sizes and performance. One of the leaders in the number of all possible variations of such high-speed data storage devices takes well-known company OCZ Storage Solutions. Such popularity has appeared primarily due to the fact that in most cases its products are focused on the high-speed systems for gamers and enthusiasts, but at the same time they are not cheap.

OCZ ARC 100 (ARC100-25SAT3-240G)

Now the company offers low cost model of SSD-drives. It is worth noting that the low cost is a quite relative concept, because everything is relative. Thus, in this article we present to your attention a relatively inexpensive, but interesting enough SSD OCZ ARC 100 with capacity of 240 GB.

Specification can be characterized as sufficiently detailed. Here the manufacturer provided details about the operating temperature and limits of vibration and shock loads. A special attention should be paid to the maximum operating temperature of the device which is equal to 70°C. This value is high enough, and it shows the possibility of using the disk even in compact systems that have some problems with cooling. Given the thickness of 6.7 mm, it can be used even in Ultrabooks with high-performance processors. Speed characteristics are a bit modest when compared with the OCZ VECTOR 150, but the cost is uniquely more pleasant.

Traditionally, the maximum speed of the solid-state drives depends on the capacity:


120 GB

240 GB

480 GB

Max consistent read speed, MB/s




Max consistent write speed, MB/s




Random read of 4 KB blocks, IOPS

75 000

75 000

75 000

Random write of 4 KB blocks, IOPS

80 000

The tested model with capacity of 240 GB takes a golden mean in performance, but the speed dispersion is not as significant as it was when considering the disks from other families.

Packaging and content

OCZ ARC 100 (ARC100-25SAT3-240G)

SSD-drive comes in a cardboard box of compact dimensions. Color design of the front side is identical to the drive, which creates a certain style and individual awareness of SSDs from one line. The additional information contains only the capacity of new item (240 GB).

OCZ ARC 100 (ARC100-25SAT3-240G)

The back has the basic information regarding the characteristics of OCZ ARC 100 with capacity of 240 GB, as well as basic information about the benefits of solid-state drives in this series. In addition, here is indicated by a small advertising product description in twelve languages.

In order to increase the attractiveness the developers set a low price for the device, but this is not reflected on its configuration. It is minimal and includes only the disk, so you may need screws and/or adapter for mounting in slot of 3.5'' devices.

Design and features

OCZ ARC 100 (ARC100-25SAT3-240G)

The case of the model OCZ ARC 100 is made of aluminum, which provides a fairly good durability and stylish appearance. The only decoration is a blue sticker on the front side. It indicats the series and manufacturer.

OCZ ARC 100 (ARC100-25SAT3-240G)

On the reverse side you will notice the label comprising all of the basic technical information about the device. Here are: the model name, serial number, power options, as well as logos, confirming the passage of the device of various certifications. Along the edges there are four mounting holes for mounting the drive in a 3.5-inch adapter.

It is not the first time when we notice that developers set special thermal spacers for heat dissipation on the aluminum body of the disc. Due to this the temperature of controller will be within the acceptable range that will positively affect the life cycle.

Key control role performs controller OCZ (Indilinx) Barefoot 3 M10 labeled as «IDX500M10-BC». The main features of this chip are:

  • the presence of two computational processors (ARM Cortex and OCZ Aragon);
  • reduced frequency of ARM-based processors, thus reducing the power consumption;
  • support for encryption using 256-bit AES-algorithm;
  • 8-channel memory controller.

This controller is almost twin brother of Indilinx Barefoot 3 installed in OCZ Vertex 150 with capacity of 240 GB, but there are some differences. In particular we are talking about the frequency of ARM-based processors, which in lower in the test drive.

The memory chips are placed on both side of the board. Chips produced by Toshiba labeled «TH58TEG7DDKBA4C», made on 19-nm process technology with multi-level-cell (MLC) are applied. A total number is 16 banks with capacity of 16 GB each. Total amount is 256 GB. 240 GB are allocated for the needs of the user. Reserved 16 GB are used to maintain high performance and correct operation of the disc.

Power control is provided by chip Texas Instruments TPS652510, which is responsible for synchronous voltage conversion.

Two chips of company Micron with FBGA-code "D9PSH" act as cache memory. Each of them has a capacity of 2 Gb/s (256 MB) and runs with the frequency of DDR3-1600 MHz with voltage of 1.35 V.

OCZ ARC 100 (ARC100-25SAT3-240G)

SSD-drive comes formatted for NTFS file system. In fact the user has a slightly smaller amount of free space: 223 GB instead of 240 GB stated. This is connected with the ubiquitous transfer of decimal values.
